+
+## v1.6 [2018-04-16]
+
+### Release Notes
+
+- The `mysql` input plugin has been updated fix a number of type convertion
+  issues.  This may cause a `field type error` when inserting into InfluxDB due
+  the change of types.
+
+  To address this we have introduced a new `metric_version` option to control
+  enabling the new format.  For in depth recommendations on upgrading please
+  reference the [mysql plugin documentation](./plugins/inputs/mysql/README.md#metric-version).
+
+  It is encouraged to migrate to the new model when possible as the old version
+  is deprecated and will be removed in a future version.
+
+- The `postgresql` plugins now defaults to using a persistent connection to the database.
+  In environments where TCP connections are terminated the `max_lifetime`
+  setting should be set less than the collection `interval` to prevent errors.
+
+- The `sqlserver` input plugin has a new query and data model that can be enabled
+  by setting `query_version = 2`.  It is encouraged to migrate to the new
+  model when possible as the old version is deprecated and will be removed in
+  a future version.
+
+- An option has been added to the `openldap` input plugin that reverses metric
+  name to improve grouping.  This change is enabled when `reverse_metric_names = true`
+  is set.  It is encouraged to enable this option when possible as the old
+  ordering is deprecated.
+
+- The new `http` input configured with `data_format = "json"` can perform the
+  same task as the, now deprecated, `httpjson` input.
+

+### Release Notes
+
+- In the `kinesis` output, use of the `partition_key` and
+  `use_random_partitionkey` options has been deprecated in favor of the
+  `partition` subtable.  This allows for more flexible methods to set the
+  partition key such as by metric name or by tag.
+
+- With the release of the new improved `jolokia2` input, the legacy `jolokia`
+  plugin is deprecated and will be removed in a future release.  Users of this
+  plugin are encouraged to update to the new `jolokia2` plugin.
+
+- In the `postgresql` and `postgresql_extensible` plugins, the type of the oid
+  data type has changed from string to integer.  It is recommended to drop
+  affected fields until a new shard is started. For details on how to
+  workaround this issue please see [#3622](https://github.com/influxdata/telegraf/issues/3622).

+
+## v1.3 [2017-05-15]
+
+### Release Notes
+
+- Users of the windows `ping` plugin will need to drop or migrate their
+measurements in order to continue using the plugin. The reason for this is that
+the windows plugin was outputting a different type than the linux plugin. This
+made it impossible to use the `ping` plugin for both windows and linux
+machines.
+
+- Ceph: the `ceph_pgmap_state` metric content has been modified to use a unique field `count`, with each state expressed as a `state` tag.
+
+Telegraf < 1.3:
+
+```
+# field_name             value
+active+clean             123
+active+clean+scrubbing   3
+```
+
+Telegraf >= 1.3:
+
+```
+# field_name    value       tag
+count           123         state=active+clean
+count           3           state=active+clean+scrubbing
+```
+
+- The [Riemann output plugin](./plugins/outputs/riemann) has been rewritten
+and the previous riemann plugin is _incompatible_ with the new one. The reasons
+for this are outlined in issue [#1878](https://github.com/influxdata/telegraf/issues/1878).
+The previous riemann output will still be available using
+`outputs.riemann_legacy` if needed, but that will eventually be deprecated.
+It is highly recommended that all users migrate to the new riemann output plugin.
+
+- Generic [socket_listener](./plugins/inputs/socket_listener) and
+[socket_writer](./plugins/outputs/socket_writer) plugins have been implemented
+for receiving and sending UDP, TCP, unix, & unix-datagram data. These plugins
+will replace udp_listener and tcp_listener, which are still available but will
+be deprecated eventually.

+## v1.2.1 [2017-02-01]
+
+### Bugfixes
+
+- [#2317](https://github.com/influxdata/telegraf/issues/2317): Fix segfault on nil metrics with influxdb output.
+- [#2324](https://github.com/influxdata/telegraf/issues/2324): Fix negative number handling.
+
+### Features
+
+- [#2348](https://github.com/influxdata/telegraf/pull/2348): Go version 1.7.4 -> 1.7.5
+
+## v1.2 [2017-01-00]
+
+### Release Notes
+
+- The StatsD plugin will now default all "delete_" config options to "true". This
+will change te default behavior for users who were not specifying these parameters
+in their config file.
+
+- The StatsD plugin will also no longer save it's state on a service reload.
+Essentially we have reverted PR [#887](https://github.com/influxdata/telegraf/pull/887).
+The reason for this is that saving the state in a global variable is not
+thread-safe (see [#1975](https://github.com/influxdata/telegraf/issues/1975) & [#2102](https://github.com/influxdata/telegraf/issues/2102)),
+and this creates issues if users want to define multiple instances
+of the statsd plugin. Saving state on reload may be considered in the future,
+but this would need to be implemented at a higher level and applied to all
+plugins, not just statsd.

 ## Unit Tests

+Before opening a pull request you should run the linter checks and
+the short tests.
+
+### Execute linter
+
+execute `make lint`
+
 ### Execute short tests

-execute `make test-short`
+execute `make test`

-### Execute long tests
+### Execute integration tests

-As Telegraf collects metrics from several third-party services it becomes a
-difficult task to mock each service as some of them have complicated protocols
-which would take some time to replicate.
+Running the integration tests requires several docker containers to be
+running.  You can start the containers with:
+```
+make docker-run
+```

-To overcome this situation we've decided to use docker containers to provide a
-fast and reproducible environment to test those services which require it.
-For other situations
-(i.e: https://github.com/influxdata/telegraf/blob/master/plugins/inputs/redis/redis_test.go)
-a simple mock will suffice.
+And run the full test suite with:
+```
+make test-all
+```

-To execute Telegraf tests follow these simple steps:
-
- Install docker following [these](https://docs.docker.com/installation/)
-instructions
- execute `make test`
-
-### Unit test troubleshooting

 # Telegraf [![Circle CI](https://circleci.com/gh/influxdata/telegraf.svg?style=svg)](https://circleci.com/gh/influxdata/telegraf) [![Docker pulls](https://img.shields.io/docker/pulls/library/telegraf.svg)](https://hub.docker.com/_/telegraf/)

-Telegraf is an agent written in Go for collecting metrics from the system it's
-running on, or from other services, and writing them into InfluxDB or other
-[outputs](https://github.com/influxdata/telegraf#supported-output-plugins).
+Telegraf is an agent written in Go for collecting, processing, aggregating,
+and writing metrics.

 Design goals are to have a minimal memory footprint with a plugin system so
 that developers in the community can easily add support for collecting metrics
-from well known services (like Hadoop, Postgres, or Redis) and third party
-APIs (like Mailchimp, AWS CloudWatch, or Google Analytics).
+.  For an example configuration referencet from local or remote services.

-New input and output plugins are designed to be easy to contribute,
+Telegraf is plugin-driven and has the concept of 4 distinct plugins:
+
+1. [Input Plugins](#input-plugins) collect metrics from the system, services, or 3rd party APIs
+2. [Processor Plugins](#processor-plugins) transform, decorate, and/or filter metrics
+3. [Aggregator Plugins](#aggregator-plugins) create aggregate metrics (e.g. mean, min, max, quantiles, etc.)
+4. [Output Plugins](#output-plugins) write metrics to various destinations
+
+For more information on Processor and Aggregator plugins please [read this](./docs/AGGREGATORS_AND_PROCESSORS.md).
+
+New plugins are designed to be easy to contribute,
 we'll eagerly accept pull
 requests and will manage the set of plugins that Telegraf supports.
-See the [contributing guide](CONTRIBUTING.md) for instructions on writing
-new plugins.
+

+which is installed by the Makefile if you don't have it already.

 1. [Install Go](https://golang.org/doc/install)
 2. [Setup your GOPATH](https://golang.org/doc/code.html#GOPATH)
-3. Run `go get github.com/influxdata/telegraf`
+3. Run `go get -d github.com/influxdata/telegraf`
 4. Run `cd $GOPATH/src/github.com/influxdata/telegraf`
 5. Run `make`

-We'll be adding support for many more over the coming months. Read on if you
-want to add support for another service or third-party API.
+Telegraf is able to parse the following input data formats into metrics, these
+formats may be used with input plugins supporting the `data_format` option:

+
+Both Aggregators and Processors analyze metrics as they pass through Telegraf.
+
+Use [measurement filtering](CONFIGURATION.md#measurement-filtering)
+to control which metrics are passed through a processor or aggregator.  If a
+metric is filtered out the metric bypasses the plugin and is passed downstream
+to the next plugin.
+
+**Processor** plugins process metrics as they pass through and immediately emit
+results based on the values they process. For example, this could be printing
+all metrics or adding a tag to all metrics that pass through.
+
+**Aggregator** plugins, on the other hand, are a bit more complicated. Aggregators
+are typically for emitting new _aggregate_ metrics, such as a running mean,
+minimum, maximum, quantiles, or standard deviation. For this reason, all _aggregator_
+plugins are configured with a `period`. The `period` is the size of the window
+of metrics that each _aggregate_ represents. In other words, the emitted
+_aggregate_ metric will be the aggregated value of the past `period` seconds.
+Since many users will only care about their aggregates and not every single metric
+gathered, there is also a `drop_original` argument, which tells Telegraf to only
+emit the aggregates and not the original metrics.
+
+**NOTE** That since aggregators only aggregate metrics within their period, that
+historical data is not supported. In other words, if your metric timestamp is more
+than `now() - period` in the past, it will not be aggregated. If this is a feature
+that you need, please comment on this [github issue](https://github.com/influxdata/telegraf/issues/1992)

 #### Measurement Filtering

 Filters can be configured per input, output, processor, or aggregator,
 see below for examples.

-* **namepass**: An array of strings that is used to filter metrics generated by the
-current input. Each string in the array is tested as a glob match against
-measurement names and if it matches, the field is emitted.
-* **namedrop**: The inverse of pass, if a measurement name matches, it is not emitted.
-* **fieldpass**: An array of strings that is used to filter metrics generated by the
-current input. Each string in the array is tested as a glob match against field names
-and if it matches, the field is emitted. fieldpass is not available for outputs.
-* **fielddrop**: The inverse of pass, if a field name matches, it is not emitted.
-fielddrop is not available for outputs.
-* **tagpass**: tag names and arrays of strings that are used to filter
-measurements by the current input. Each string in the array is tested as a glob
-match against the tag name, and if it matches the measurement is emitted.
-* **tagdrop**: The inverse of tagpass. If a tag matches, the measurement is not
-emitted. This is tested on measurements that have passed the tagpass test.
-* **tagexclude**: tagexclude can be used to exclude a tag from measurement(s).
-As opposed to tagdrop, which will drop an entire measurement based on it's
-tags, tagexclude simply strips the given tag keys from the measurement. This
-can be used on inputs & outputs, but it is _recommended_ to be used on inputs,
-as it is more efficient to filter out tags at the ingestion point.
-* **taginclude**: taginclude is the inverse of tagexclude. It will only include
-the tag keys in the final measurement.
+* **namepass**:
+An array of glob pattern strings.  Only points whose measurement name matches
+a pattern in this list are emitted.
+* **namedrop**:
+The inverse of `namepass`.  If a match is found the point is discarded. This
+is tested on points after they have passed the `namepass` test.
+* **fieldpass**:
+An array of glob pattern strings.  Only fields whose field key matches a
+pattern in this list are emitted.
+* **fielddrop**:
+The inverse of `fieldpass`.  Fields with a field key matching one of the
+patterns will be discarded from the point.  This is tested on points after
+they have passed the `fieldpass` test.
+* **tagpass**:
+A table mapping tag keys to arrays of glob pattern strings.  Only points
+that contain a tag key in the table and a tag value matching one of its
+patterns is emitted.
+* **tagdrop**:
+The inverse of `tagpass`.  If a match is found the point is discarded. This
+is tested on points after they have passed the `tagpass` test.
+* **taginclude**:
+An array of glob pattern strings.  Only tags with a tag key matching one of
+the patterns are emitted.  In contrast to `tagpass`, which will pass an entire
+point based on its tag, `taginclude` removes all non matching tags from the
+point.  This filter can be used on both inputs & outputs, but it is
+_recommended_ to be used on inputs, as it is more efficient to filter out tags
+at the ingestion point.
+* **tagexclude**:
+The inverse of `taginclude`. Tags with a tag key matching one of the patterns
+will be discarded from the point.

-**NOTE** `tagpass` and `tagdrop` parameters must be defined at the _end_ of
-the plugin definition, otherwise subsequent plugin config options will be
-interpreted as part of the tagpass/tagdrop map.
+**NOTE** Due to the way TOML is parsed, `tagpass` and `tagdrop` parameters
+must be defined at the _end_ of the plugin definition, otherwise subsequent
+plugin config options will be interpreted as part of the tagpass/tagdrop
+tables.

+
+For more information about the binary network protocol see

+set the desired security level in `collectd_security_level`.
+
+Additional information including client setup can be found

+# Dropwizard:
+
+The dropwizard format can parse the JSON representation of a single dropwizard metric registry. By default, tags are parsed from metric names as if they were actual influxdb line protocol keys (`measurement<,tag_set>`) which can be overriden by defining custom [measurement & tag templates](./DATA_FORMATS_INPUT.md#measurement--tag-templates). All field value types are supported, `string`, `number` and `boolean`.
+
+A typical JSON of a dropwizard metric registry:
+
+```json
+{
+	"version": "3.0.0",
+	"counters" : {
+		"measurement,tag1=green" : {
+			"count" : 1
+		}
+	},
+	"meters" : {
+		"measurement" : {
+			"count" : 1,
+			"m15_rate" : 1.0,
+			"m1_rate" : 1.0,
+			"m5_rate" : 1.0,
+			"mean_rate" : 1.0,
+			"units" : "events/second"
+		}
+	},
+	"gauges" : {
+		"measurement" : {
+			"value" : 1
+		}
+	},
+	"histograms" : {
+		"measurement" : {
+			"count" : 1,
+			"max" : 1.0,
+			"mean" : 1.0,
+			"min" : 1.0,
+			"p50" : 1.0,
+			"p75" : 1.0,
+			"p95" : 1.0,
+			"p98" : 1.0,
+			"p99" : 1.0,
+			"p999" : 1.0,
+			"stddev" : 1.0
+		}
+	},
+	"timers" : {
+		"measurement" : {
+			"count" : 1,
+			"max" : 1.0,
+			"mean" : 1.0,
+			"min" : 1.0,
+			"p50" : 1.0,
+			"p75" : 1.0,
+			"p95" : 1.0,
+			"p98" : 1.0,
+			"p99" : 1.0,
+			"p999" : 1.0,
+			"stddev" : 1.0,
+			"m15_rate" : 1.0,
+			"m1_rate" : 1.0,
+			"m5_rate" : 1.0,
+			"mean_rate" : 1.0,
+			"duration_units" : "seconds",
+			"rate_units" : "calls/second"
+		}
+	}
+}
+```
+
+Would get translated into 4 different measurements:
+
+```
+measurement,metric_type=counter,tag1=green count=1
+measurement,metric_type=meter count=1,m15_rate=1.0,m1_rate=1.0,m5_rate=1.0,mean_rate=1.0
+measurement,metric_type=gauge value=1
+measurement,metric_type=histogram count=1,max=1.0,mean=1.0,min=1.0,p50=1.0,p75=1.0,p95=1.0,p98=1.0,p99=1.0,p999=1.0
+measurement,metric_type=timer count=1,max=1.0,mean=1.0,min=1.0,p50=1.0,p75=1.0,p95=1.0,p98=1.0,p99=1.0,p999=1.0,stddev=1.0,m15_rate=1.0,m1_rate=1.0,m5_rate=1.0,mean_rate=1.0
+```
+
+You may also parse a dropwizard registry from any JSON document which contains a dropwizard registry in some inner field. 
+Eg. to parse the following JSON document:
+
+```json
+{
+	"time" : "2017-02-22T14:33:03.662+02:00",
+	"tags" : {
+		"tag1" : "green",
+		"tag2" : "yellow"
+	},
+	"metrics" : {
+		"counters" : 	{ 
+			"measurement" : {
+				"count" : 1
+			}
+		},
+		"meters" : {},
+		"gauges" : {},
+		"histograms" : {},
+		"timers" : {}
+	}
+}
+```
+and translate it into:
+
+```
+measurement,metric_type=counter,tag1=green,tag2=yellow count=1 1487766783662000000
+```
+
+you simply need to use the following additional configuration properties:
+
+```toml
+dropwizard_metric_registry_path = "metrics"
+dropwizard_time_path = "time"
+dropwizard_time_format = "2006-01-02T15:04:05Z07:00"
+dropwizard_tags_path = "tags"
+## tag paths per tag are supported too, eg.
+#[inputs.yourinput.dropwizard_tag_paths]
+#  tag1 = "tags.tag1"
+#  tag2 = "tags.tag2"
+```
+

+plugins.

-
-Telegraf metrics, like InfluxDB
-[points](https://docs.influxdata.com/influxdb/v0.10/write_protocols/line/),
-are a combination of four basic parts:
-
-1. Measurement Name
-1. Tags
-1. Fields
-1. Timestamp
-
-In InfluxDB line protocol, these 4 parts are easily defined in textual form:
-
-```
-measurement_name[,tag1=val1,...]  field1=val1[,field2=val2,...]  [timestamp]
-```
-
-For Telegraf outputs that write textual data (such as `kafka`, `mqtt`, and `file`),
-InfluxDB line protocol was originally the only available output format. But now
-we are normalizing telegraf metric "serializers" into a
-[plugin-like interface](https://github.com/influxdata/telegraf/tree/master/plugins/serializers)
-across all output plugins that can support it.
-You will be able to identify a plugin that supports different data formats
-by the presence of a `data_format`
-config option, for example, in the `file` output plugin:

+# Frequently Asked Questions
+
+### Q: How can I monitor the Docker Engine Host from within a container?
+
+You will need to setup several volume mounts as well as some environment
+variables:
+```
+docker run --name telegraf
+	-v /:/hostfs:ro
+	-v /etc:/hostfs/etc:ro
+	-v /proc:/hostfs/proc:ro
+	-v /sys:/hostfs/sys:ro
+	-v /var/run/utmp:/var/run/utmp:ro
+	-e HOST_ETC=/hostfs/etc
+	-e HOST_PROC=/hostfs/proc
+	-e HOST_SYS=/hostfs/sys
+	-e HOST_MOUNT_PREFIX=/hostfs
+	telegraf
+```
+
+
+### Q: Why do I get a "no such host" error resolving hostnames that other
+programs can resolve?
+
+Go uses a pure Go resolver by default for [name resolution](https://golang.org/pkg/net/#hdr-Name_Resolution).
+This resolver behaves differently than the C library functions but is more
+efficient when used with the Go runtime.
+
+If you encounter problems or want to use more advanced name resolution methods
+that are unsupported by the pure Go resolver, you can switch to the cgo
+resolver.
+
+If running manually set:
+```
+export GODEBUG=netdns=cgo
+```
+
+If running as a service add the environment variable to `/etc/default/telegraf`:
+```
+GODEBUG=netdns=cgo
+```
+
+### Q: When will the next version be released?
+
+The latest release date estimate can be viewed on the
+[milestones](https://github.com/influxdata/telegraf/milestones) page.

+# Telegraf profiling
+
+Telegraf uses the standard package `net/http/pprof`. This package serves via its HTTP server runtime profiling data in the format expected by the pprof visualization tool.
+
+By default, the profiling is turned off.
+
+To enable profiling you need to specify address to config parameter `pprof-addr`, for example:
+
+```
+telegraf --config telegraf.conf --pprof-addr localhost:6060
+```
+
+There are several paths to get different profiling information:
+
+To look at the heap profile:
+
+`go tool pprof http://localhost:6060/debug/pprof/heap`
+
+or to look at a 30-second CPU profile:
+
+`go tool pprof http://localhost:6060/debug/pprof/profile?seconds=30`
+
+To view all available profiles, open `http://localhost:6060/debug/pprof/` in your browser.

+# BasicStats Aggregator Plugin
+
+The BasicStats aggregator plugin give us count,max,min,mean,sum,s2(variance), stdev for a set of values,
+emitting the aggregate every `period` seconds.
+
+### Configuration:
+
+```toml
+# Keep the aggregate basicstats of each metric passing through.
+[[aggregators.basicstats]]
+
+  ## General Aggregator Arguments:
+
+  ## The period on which to flush & clear the aggregator.
+  period = "30s"
+
+  ## If true, the original metric will be dropped by the
+  ## aggregator and will not get sent to the output plugins.
+  drop_original = false
+
+  ## BasicStats Arguments:
+
+  ## Configures which basic stats to push as fields
+  stats = ["count","min","max","mean","stdev","s2","sum"]
+```
+
+- stats
+    - If not specified, then `count`, `min`, `max`, `mean`, `stdev`, and `s2` are aggregated and pushed as fields.  `sum` is not aggregated by default to maintain backwards compatibility.
+    - If empty array, no stats are aggregated
+
+### Measurements & Fields:
+
+- measurement1
+    - field1_count
+    - field1_max
+    - field1_min
+    - field1_mean
+    - field1_sum
+    - field1_s2 (variance)
+    - field1_stdev (standard deviation)
+
+### Tags:
+
+No tags are applied by this aggregator.
+
+### Example Output:
+
+```
+$ telegraf --config telegraf.conf --quiet

+Values added to a bucket are also added to the larger buckets in the
+distribution.  This creates a [cumulative histogram](https://en.wikipedia.org/wiki/Histogram#/media/File:Cumulative_vs_normal_histogram.svg).
+
+Like other Telegraf aggregators, the metric is emitted every `period` seconds.
+Bucket counts however are not reset between periods and will be non-strictly
+increasing while Telegraf is running.
+
+#### Design
+
+Each metric is passed to the aggregator and this aggregator searches
+histogram buckets for those fields, which have been specified in the
+config. If buckets are found, the aggregator will increment +1 to the appropriate
+bucket otherwise it will be added to the `+Inf` bucket.  Every `period`
+seconds this data will be forwarded to the outputs.
+
+The algorithm of hit counting to buckets was implemented on the base
+of the algorithm which is implemented in the Prometheus
+[client](https://github.com/prometheus/client_golang/blob/master/prometheus/histogram.go).
+
+### Configuration
+
+```toml
+# Configuration for aggregate histogram metrics
+[[aggregators.histogram]]
+  ## The period in which to flush the aggregator.
+  period = "30s"
+
+  ## If true, the original metric will be dropped by the
+  ## aggregator and will not get sent to the output plugins.
+  drop_original = false
+
+  ## Example config that aggregates all fields of the metric.
+  # [[aggregators.histogram.config]]
+  #   ## The set of buckets.
+  #   buckets = [0.0, 15.6, 34.5, 49.1, 71.5, 80.5, 94.5, 100.0]
+  #   ## The name of metric.
+  #   measurement_name = "cpu"
+
+  ## Example config that aggregates only specific fields of the metric.
+  # [[aggregators.histogram.config]]
+  #   ## The set of buckets.
+  #   buckets = [0.0, 10.0, 20.0, 30.0, 40.0, 50.0, 60.0, 70.0, 80.0, 90.0, 100.0]
+  #   ## The name of metric.
+  #   measurement_name = "diskio"
+  #   ## The concrete fields of metric
+  #   fields = ["io_time", "read_time", "write_time"]
+```
+
+The user is responsible for defining the bounds of the histogram bucket as
+well as the measurement name and fields to aggregate.
+
+Each histogram config section must contain a `buckets` and `measurement_name`
+option.  Optionally, if `fields` is set only the fields listed will be
+aggregated.  If `fields` is not set all fields are aggregated.
+
+The `buckets` option contains a list of floats which specify the bucket
+boundaries.  Each float value defines the inclusive upper bound of the bucket.
+The `+Inf` bucket is added automatically and does not need to be defined.
+
+### Measurements & Fields:
+
+The postfix `bucket` will be added to each field key.
+
+- measurement1
+    - field1_bucket
+    - field2_bucket
+
+### Tags:
+
+All measurements are given the tag `le`. This tag has the border value of
+bucket. It means that the metric value is less than or equal to the value of
+this tag.  For example, let assume that we have the metric value 10 and the
+following buckets: [5, 10, 30, 70, 100]. Then the tag `le` will have the value
+10, because the metrics value is passed into bucket with right border value
+`10`.
+
+### Example Output:
+
+```
+cpu,cpu=cpu1,host=localhost,le=0.0 usage_idle_bucket=0i 1486998330000000000
+cpu,cpu=cpu1,host=localhost,le=10.0 usage_idle_bucket=0i 1486998330000000000

+# ValueCounter Aggregator Plugin
+
+The valuecounter plugin counts the occurrence of values in fields and emits the
+counter once every 'period' seconds.
+
+A use case for the valuecounter plugin is when you are processing a HTTP access
+log (with the logparser input) and want to count the HTTP status codes.
+
+The fields which will be counted must be configured with the `fields`
+configuration directive. When no `fields` is provided the plugin will not count
+any fields. The results are emitted in fields in the format:
+`originalfieldname_fieldvalue = count`.
+
+Valuecounter only works on fields of the type int, bool or string. Float fields
+are being dropped to prevent the creating of too many fields.
+
+### Configuration:
+
+```toml
+[[aggregators.valuecounter]]
+  ## General Aggregator Arguments:
+  ## The period on which to flush & clear the aggregator.
+  period = "30s"
+  ## If true, the original metric will be dropped by the
+  ## aggregator and will not get sent to the output plugins.
+  drop_original = false
+  ## The fields for which the values will be counted
+  fields = ["status"]
+```
+
+### Measurements & Fields:
+
+- measurement1
+    - field_value1
+    - field_value2

+### Tags:

+No tags are applied by this aggregator.

+
 ```toml
 # Description
 [[inputs.example]]
-  # SampleConfig
+  example_option = "example_value"
 ```

-### Measurements & Fields:
+### Metrics:

-<optional description>
+Here you should add an optional description and links to where the user can
+get more information about the measurements.
+
+If the output is determined dynamically based on the input source, or there
+are more metrics than can reasonably be listed, describe how the input is
+mapped to the output.

 - measurement1
-    - field1 (type, unit)
-    - field2 (float, percent)
- measurement2
-    - field3 (integer, bytes)

+Get the max, mean, and min for the measurement in the last hour:
 ```
 SELECT max(field1), mean(field1), min(field1) FROM measurement1 WHERE tag1=bar AND time > now() - 1h GROUP BY tag
 ```

 ### Example Output:

+This section shows example output in Line Protocol format.  You can often use
+`telegraf --input-filter <plugin-name> --test` or use the `file` output to get
+this information.

+# AMQP Consumer Input Plugin
+
+This plugin provides a consumer for use with AMQP 0-9-1, a promenent implementation of this protocol being [RabbitMQ](https://www.rabbitmq.com/).
+
+Metrics are read from a topic exchange using the configured queue and binding_key.
+
+Message payload should be formatted in one of the [Telegraf Data Formats](https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_INPUT.md).
+
+For an introduction to AMQP see:
+- https://www.rabbitmq.com/tutorials/amqp-concepts.html
+- https://www.rabbitmq.com/getstarted.html
+
+The following defaults are known to work with RabbitMQ:
+
+```toml
+# AMQP consumer plugin
+[[inputs.amqp_consumer]]
+  ## Broker to consume from.
+  ##   deprecated in 1.7; use the brokers option
+  # url = "amqp://localhost:5672/influxdb"
+
+  ## Brokers to consume from.  If multiple brokers are specified a random broker
+  ## will be selected anytime a connection is established.  This can be
+  ## helpful for load balancing when not using a dedicated load balancer.
+  brokers = ["amqp://localhost:5672/influxdb"]
+
+  ## Authentication credentials for the PLAIN auth_method.
+  # username = ""
+  # password = ""
+
+  ## Exchange to declare and consume from.
+  exchange = "telegraf"
+
+  ## Exchange type; common types are "direct", "fanout", "topic", "header", "x-consistent-hash".
+  # exchange_type = "topic"
+
+  ## If true, exchange will be passively declared.
+  # exchange_passive = false
+
+  ## Exchange durability can be either "transient" or "durable".
+  # exchange_durability = "durable"
+
+  ## Additional exchange arguments.
+  # exchange_arguments = { }
+  # exchange_arguments = {"hash_propery" = "timestamp"}
+
+  ## AMQP queue name
+  queue = "telegraf"
+  ## Binding Key
+  binding_key = "#"
+
+  ## Maximum number of messages server should give to the worker.
+  # prefetch_count = 50
+
+  ## Auth method. PLAIN and EXTERNAL are supported
+  ## Using EXTERNAL requires enabling the rabbitmq_auth_mechanism_ssl plugin as
+  ## described here: https://www.rabbitmq.com/plugins.html
+  # auth_method = "PLAIN"

+  ## Optional TLS Config
+  # tls_ca = "/etc/telegraf/ca.pem"

-# Telegraf plugin: Apache
+# Apache Input Plugin

-#### Plugin arguments:
- **urls** []string: List of apache-status URLs to collect from. Default is "http://localhost/server-status?auto".
+The Apache plugin collects server performance information using the [`mod_status`](https://httpd.apache.org/docs/2.4/mod/mod_status.html) module of the [Apache HTTP Server](https://httpd.apache.org/).

-#### Description
+Typically, the `mod_status` module is configured to expose a page at the `/server-status?auto` location of the Apache server.  The [ExtendedStatus](https://httpd.apache.org/docs/2.4/mod/core.html#extendedstatus) option must be enabled in order to collect all available fields.  For information about how to configure your server reference the [module documentation](https://httpd.apache.org/docs/2.4/mod/mod_status.html#enable).

-The Apache plugin collects from the /server-status?auto URL. See
-[apache.org/server-status?auto](http://www.apache.org/server-status?auto) for an
-example. And
-[here](http://httpd.apache.org/docs/2.2/mod/mod_status.html) for the apache
-mod_status documentation.
+### Configuration:

-# Measurements:
+```toml
+# Read Apache status information (mod_status)
+[[inputs.apache]]
+  ## An array of URLs to gather from, must be directed at the machine
+  ## readable version of the mod_status page including the auto query string.
+  ## Default is "http://localhost/server-status?auto".
+  urls = ["http://localhost/server-status?auto"]

-Meta:
- tags: `port=<port>`, `server=url`
+  ## Credentials for basic HTTP authentication.
+  # username = "myuser"
+  # password = "mypassword"

+# Bond Input Plugin
+
+The Bond input plugin collects network bond interface status for both the
+network bond interface as well as slave interfaces.
+The plugin collects these metrics from `/proc/net/bonding/*` files.
+
+### Configuration:
+
+```toml
+[[inputs.bond]]
+  ## Sets 'proc' directory path
+  ## If not specified, then default is /proc
+  # host_proc = "/proc"
+
+  ## By default, telegraf gather stats for all bond interfaces
+  ## Setting interfaces will restrict the stats to the specified
+  ## bond interfaces.
+  # bond_interfaces = ["bond0"]
+```
+
+### Measurements & Fields:
+
+- bond
+  - active_slave (for active-backup mode)
+  - status
+
+- bond_slave
+  - failures
+  - status
+
+### Description:
+
+```
+active_slave
+  Currently active slave interface for active-backup mode.
+
+status
+  Status of bond interface or bonds's slave interface (down = 0, up = 1).
+
+failures
+  Amount of failures for bond's slave interface.
+```
+
+### Tags:
+
+- bond
+  - bond
+
+- bond_slave
+  - bond
+  - interface
+
+### Example output:
