-## v0.10.2 [unreleased]
+## v1.0 Release Candidate 1 [2016-08-23]
+
+### Release Notes
+
+**Breaking Change** The SNMP plugin is being deprecated in it's current form.
+There is a [new SNMP plugin](https://github.com/influxdata/telegraf/tree/master/plugins/inputs/snmp)
+which fixes many of the issues and confusions
+of it's predecessor. For users wanting to continue to use the deprecated SNMP
+plugin, you will need to change your config file from `[[inputs.snmp]]` to
+`[[inputs.snmp_legacy]]`. The configuration of the new SNMP plugin is _not_
+backwards-compatible.
+
+- Telegraf now supports being installed as an official windows service,
+which can be installed via
+`> C:\Program Files\Telegraf\telegraf.exe --service install`
+
+**Breaking Change**: Aerospike main server node measurements have been renamed
+aerospike_node. Aerospike namespace measurements have been renamed to
+aerospike_namespace. They will also now be tagged with the node_name
+that they correspond to. This has been done to differentiate measurements
+that pertain to node vs. namespace statistics.
+
+**Breaking Change**: users of github_webhooks must change to the new
+`[[inputs.webhooks]]` plugin.
+
+This means that the default github_webhooks config:
+
+```
+# A Github Webhook Event collector
+[[inputs.github_webhooks]]
+  ## Address and port to host Webhook listener on
+  service_address = ":1618"
+```
+
+should now look like:
+
+```
+# A Webhooks Event collector
+[[inputs.webhooks]]
+  ## Address and port to host Webhook listener on
+  service_address = ":1618"
+
+  [inputs.webhooks.github]
+    path = "/"
+```
+
+- `flush_jitter` behavior has been changed. The random jitter will now be
+evaluated at every flush interval, rather than once at startup. This makes it
+consistent with the behavior of `collection_jitter`.

+
+### Release Notes
+
+- net_response and http_response plugins timeouts will now accept duration

+
+## v0.13 [2016-05-11]
+
+### Release Notes
+
+- **Breaking change** in jolokia plugin. See
+https://github.com/influxdata/telegraf/blob/master/plugins/inputs/jolokia/README.md
+for updated configuration. The plugin will now support proxy mode and will make
+POST requests.
+
+- New [agent] configuration option: `metric_batch_size`. This option tells
+telegraf the maximum batch size to allow to accumulate before sending a flush
+to the configured outputs. `metric_buffer_limit` now refers to the absolute
+maximum number of metrics that will accumulate before metrics are dropped.
+
+- There is no longer an option to
+`flush_buffer_when_full`, this is now the default and only behavior of telegraf.
+
+- **Breaking Change**: docker plugin tags. The cont_id tag no longer exists, it
+will now be a field, and be called container_id. Additionally, cont_image and
+cont_name are being renamed to container_image and container_name.
+
+- **Breaking Change**: docker plugin measurements. The `docker_cpu`, `docker_mem`,
+`docker_blkio` and `docker_net` measurements are being renamed to
+`docker_container_cpu`, `docker_container_mem`, `docker_container_blkio` and
+`docker_container_net`. Why? Because these metrics are
+specifically tracking per-container stats. The problem with per-container stats,
+in some use-cases, is that if containers are short-lived AND names are not
+kept consistent, then the series cardinality will balloon very quickly.
+So adding "container" to each metric will:
+(1) make it more clear that these metrics are per-container, and
+(2) allow users to easily drop per-container metrics if cardinality is an
+issue (`namedrop = ["docker_container_*"]`)
+
+- `tagexclude` and `taginclude` are now available, which can be used to remove
+tags from measurements on inputs and outputs. See
+[the configuration doc](https://github.com/influxdata/telegraf/blob/master/docs/CONFIGURATION.md)
+for more details.
+
+- **Measurement filtering:** All measurement filters now match based on glob
+only. Previously there was an undocumented behavior where filters would match
+based on _prefix_ in addition to globs. This means that a filter like
+`fielddrop = ["time_"]` will need to be changed to `fielddrop = ["time_*"]`
+
+- **datadog**: measurement and field names will no longer have `_` replaced by `.`
+
+- The following plugins have changed their tags to _not_ overwrite the host tag:
+  - cassandra: `host -> cassandra_host`
+  - disque: `host -> disque_host`
+  - rethinkdb: `host -> rethinkdb_host`
+
+- **Breaking Change**: The `win_perf_counters` input has been changed to
+sanitize field names, replacing `/Sec` and `/sec` with `_persec`, as well as
+spaces with underscores. This is needed because Graphite doesn't like slashes
+and spaces, and was failing to accept metrics that had them.
+The `/[sS]ec` -> `_persec` is just to make things clearer and uniform.
+
+- **Breaking Change**: snmp plugin. The `host` tag of the snmp plugin has been
+changed to the `snmp_host` tag.
+
+- The `disk` input plugin can now be configured with the `HOST_MOUNT_PREFIX` environment variable.
+This value is prepended to any mountpaths discovered before retrieving stats.
+It is not included on the report path. This is necessary for reporting host disk stats when running from within a container.

+## v0.12.1 [2016-04-14]
+
+### Release Notes
+- Breaking change in the dovecot input plugin. See Features section below.
+- Graphite output templates are now supported. See
+https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_OUTPUT.md#graphite
+- Possible breaking change for the librato and graphite outputs. Telegraf will
+no longer insert field names when the field is simply named `value`. This is
+because the `value` field is redundant in the graphite/librato context.

-}
-```
-
-### Accumulator
-
-The way that a plugin emits metrics is by interacting with the Accumulator.
-
-The `Add` function takes 3 arguments:
-* **measurement**: A string description of the metric. For instance `bytes_read` or `
-faults`.
-* **value**: A value for the metric. This accepts 5 different types of value:
-  * **int**: The most common type. All int types are accepted but favor using `int64`
-  Useful for counters, etc.
-  * **float**: Favor `float64`, useful for gauges, percentages, etc.
-  * **bool**: `true` or `false`, useful to indicate the presence of a state. `light_on`,
-  etc.
-  * **string**: Typically used to indicate a message, or some kind of freeform
-  information.
-  * **time.Time**: Useful for indicating when a state last occurred, for instance `
-  light_on_since`.
-* **tags**: This is a map of strings to strings to describe the where or who
-about the metric. For instance, the `net` plugin adds a tag named `"interface"`
-set to the name of the network interface, like `"eth0"`.

+## Input Plugins Accepting Arbitrary Data Formats
+
+Some input plugins (such as
+[exec](https://github.com/influxdata/telegraf/tree/master/plugins/inputs/exec))
+accept arbitrary input data formats. An overview of these data formats can
+be found
+[here](https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_INPUT.md).
+
+In order to enable this, you must specify a `SetParser(parser parsers.Parser)`
+function on the plugin object (see the exec plugin for an example), as well as
+defining `parser` as a field of the object.
+
+You can then utilize the parser internally in your plugin, parsing data as you
+see fit. Telegraf's configuration layer will take care of instantiating and
+creating the `Parser` object.
+
+You should also add the following to your SampleConfig() return:
+
+```toml
+  ## Data format to consume.
+  ## Each data format has it's own unique set of configuration options, read
+  ## more about them here:
+  ## https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_INPUT.md
+  data_format = "influx"
+```
+
+Below is the `Parser` interface.
+
+```go
+// Parser is an interface defining functions that a parser plugin must satisfy.
+type Parser interface {
+    // Parse takes a byte buffer separated by newlines
+    // ie, `cpu.usage.idle 90\ncpu.usage.busy 10`
+    // and parses it into telegraf metrics
+    Parse(buf []byte) ([]telegraf.Metric, error)
+
+    // ParseLine takes a single string metric
+    // ie, "cpu.usage.idle 90"
+    // and parses it into a telegraf metric.
+    ParseLine(line string) (telegraf.Metric, error)

+## Output Plugins Writing Arbitrary Data Formats
+
+Some output plugins (such as
+[file](https://github.com/influxdata/telegraf/tree/master/plugins/outputs/file))
+can write arbitrary output data formats. An overview of these data formats can
+be found
+[here](https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_OUTPUT.md).
+
+In order to enable this, you must specify a
+`SetSerializer(serializer serializers.Serializer)`
+function on the plugin object (see the file plugin for an example), as well as
+defining `serializer` as a field of the object.
+
+You can then utilize the serializer internally in your plugin, serializing data
+before it's written. Telegraf's configuration layer will take care of
+instantiating and creating the `Serializer` object.
+
+You should also add the following to your SampleConfig() return:
+
+```toml
+  ## Data format to output.
+  ## Each data format has it's own unique set of configuration options, read
+  ## more about them here:
+  ## https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_OUTPUT.md
+  data_format = "influx"
+```

+# Telegraf Input Data Formats
+
+Telegraf is able to parse the following input data formats into metrics:
+
+1. [InfluxDB Line Protocol](https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_INPUT.md#influx)
+1. [JSON](https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_INPUT.md#json)
+1. [Graphite](https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_INPUT.md#graphite)
+1. [Value](https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_INPUT.md#value), ie: 45 or "booyah"
+1. [Nagios](https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_INPUT.md#nagios) (exec input only)
+
+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
+
+These four parts are easily defined when using InfluxDB line-protocol as a
+data format. But there are other data formats that users may want to use which
+require more advanced configuration to create usable Telegraf metrics.
+
+Plugins such as `exec` and `kafka_consumer` parse textual data. Up until now,
+these plugins were statically configured to parse just a single
+data format. `exec` mostly only supported parsing JSON, and `kafka_consumer` only
+supported data in InfluxDB line-protocol.
+
+But now we are normalizing the parsing of various data formats across all
+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 exec plugin:
+
+```toml
+[[inputs.exec]]
+  ## Commands array
+  commands = ["/tmp/test.sh", "/usr/bin/mycollector --foo=bar"]
+
+  ## measurement name suffix (for separating different commands)
+  name_suffix = "_mycollector"
+
+  ## Data format to consume.
+  ## Each data format has it's own unique set of configuration options, read
+  ## more about them here:
+  ## https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_INPUT.md
+  data_format = "json"
+
+  ## Additional configuration options go here
+```
+
+Each data_format has an additional set of configuration options available, which
+I'll go over below.
+
+# Influx:
+
+There are no additional configuration options for InfluxDB line-protocol. The
+metrics are parsed directly into Telegraf metrics.
+
+#### Influx Configuration:
+
+```toml
+[[inputs.exec]]
+  ## Commands array
+  commands = ["/tmp/test.sh", "/usr/bin/mycollector --foo=bar"]
+
+  ## measurement name suffix (for separating different commands)
+  name_suffix = "_mycollector"
+
+  ## Data format to consume.
+  ## Each data format has it's own unique set of configuration options, read
+  ## more about them here:
+  ## https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_INPUT.md
+  data_format = "influx"
+```
+
+# JSON:
+
+The JSON data format flattens JSON into metric _fields_.
+NOTE: Only numerical values are converted to fields, and they are converted
+into a float. strings are ignored unless specified as a tag_key (see below).
+
+So for example, this JSON:
+
+```json
+{
+    "a": 5,
+    "b": {
+        "c": 6
+    },
+    "ignored": "I'm a string"
+}
+```
+
+Would get translated into _fields_ of a measurement:
+
+```
+myjsonmetric a=5,b_c=6
+```
+
+The _measurement_ _name_ is usually the name of the plugin,
+but can be overridden using the `name_override` config option.
+
+#### JSON Configuration:
+
+The JSON data format supports specifying "tag keys". If specified, keys
+will be searched for in the root-level of the JSON blob. If the key(s) exist,
+they will be applied as tags to the Telegraf metrics.
+
+For example, if you had this configuration:
+
+```toml
+[[inputs.exec]]
+  ## Commands array
+  commands = ["/tmp/test.sh", "/usr/bin/mycollector --foo=bar"]
+
+  ## measurement name suffix (for separating different commands)
+  name_suffix = "_mycollector"
+
+  ## Data format to consume.
+  ## Each data format has it's own unique set of configuration options, read
+  ## more about them here:
+  ## https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_INPUT.md
+  data_format = "json"
+
+  ## List of tag names to extract from top-level of JSON server response
+  tag_keys = [
+    "my_tag_1",
+    "my_tag_2"
+  ]
+```
+
+with this JSON output from a command:
+
+```json
+{
+    "a": 5,
+    "b": {
+        "c": 6
+    },
+    "my_tag_1": "foo"
+}
+```
+
+Your Telegraf metrics would get tagged with "my_tag_1"
+
+```
+exec_mycollector,my_tag_1=foo a=5,b_c=6
+```
+
+# Value:
+
+The "value" data format translates single values into Telegraf metrics. This
+is done by assigning a measurement name and setting a single field ("value")
+as the parsed metric.
+
+#### Value Configuration:
+
+You **must** tell Telegraf what type of metric to collect by using the
+`data_type` configuration option. Available options are:
+
+1. integer
+2. float or long
+3. string
+4. boolean
+
+**Note:** It is also recommended that you set `name_override` to a measurement
+name that makes sense for your metric, otherwise it will just be set to the
+name of the plugin.
+
+```toml
+[[inputs.exec]]
+  ## Commands array
+  commands = ["cat /proc/sys/kernel/random/entropy_avail"]
+
+  ## override the default metric name of "exec"
+  name_override = "entropy_available"
+
+  ## Data format to consume.
+  ## Each data format has it's own unique set of configuration options, read
+  ## more about them here:
+  ## https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_INPUT.md
+  data_format = "value"
+  data_type = "integer" # required
+```
+
+# Graphite:
+
+The Graphite data format translates graphite _dot_ buckets directly into
+telegraf measurement names, with a single value field, and without any tags.
+By default, the separator is left as ".", but this can be changed using the
+"separator" argument. For more advanced options,
+Telegraf supports specifying "templates" to translate
+graphite buckets into Telegraf metrics.
+
+Templates are of the form:
+
+```
+"host.mytag.mytag.measurement.measurement.field*"
+```
+
+Where the following keywords exist:
+
+1. `measurement`: specifies that this section of the graphite bucket corresponds
+to the measurement name. This can be specified multiple times.
+2. `field`: specifies that this section of the graphite bucket corresponds
+to the field name. This can be specified multiple times.
+3. `measurement*`: specifies that all remaining elements of the graphite bucket
+correspond to the measurement name.
+4. `field*`: specifies that all remaining elements of the graphite bucket
+correspond to the field name.
+
+Any part of the template that is not a keyword is treated as a tag key. This
+can also be specified multiple times.
+
+NOTE: `field*` cannot be used in conjunction with `measurement*`!
+
+#### Measurement & Tag Templates:
+
+The most basic template is to specify a single transformation to apply to all
+incoming metrics. So the following template:
+
+```toml
+templates = [
+    "region.region.measurement*"
+]
+```
+
+would result in the following Graphite -> Telegraf transformation.
+
+```
+us.west.cpu.load 100
+=> cpu.load,region=us.west value=100
+```
+
+#### Field Templates:
+
+The field keyword tells Telegraf to give the metric that field name.
+So the following template:
+
+```toml
+separator = "_"
+templates = [
+    "measurement.measurement.field.field.region"
+]
+```
+
+would result in the following Graphite -> Telegraf transformation.
+
+```
+cpu.usage.idle.percent.eu-east 100
+=> cpu_usage,region=eu-east idle_percent=100
+```
+
+The field key can also be derived from all remaining elements of the graphite
+bucket by specifying `field*`:
+
+```toml
+separator = "_"
+templates = [
+    "measurement.measurement.region.field*"
+]
+```
+
+which would result in the following Graphite -> Telegraf transformation.
+
+```
+cpu.usage.eu-east.idle.percentage 100
+=> cpu_usage,region=eu-east idle_percentage=100
+```
+
+#### Filter Templates:
+
+Users can also filter the template(s) to use based on the name of the bucket,
+using glob matching, like so:
+
+```toml
+templates = [
+    "cpu.* measurement.measurement.region",
+    "mem.* measurement.measurement.host"
+]
+```
+
+which would result in the following transformation:
+
+```
+cpu.load.eu-east 100
+=> cpu_load,region=eu-east value=100
+
+mem.cached.localhost 256
+=> mem_cached,host=localhost value=256
+```
+
+#### Adding Tags:
+
+Additional tags can be added to a metric that don't exist on the received metric.
+You can add additional tags by specifying them after the pattern.
+Tags have the same format as the line protocol.
+Multiple tags are separated by commas.
+
+```toml
+templates = [
+    "measurement.measurement.field.region datacenter=1a"
+]
+```
+
+would result in the following Graphite -> Telegraf transformation.
+
+```
+cpu.usage.idle.eu-east 100
+=> cpu_usage,region=eu-east,datacenter=1a idle=100
+```
+

+by the presence of a `data_format`
+config option, for example, in the `file` output plugin:
+
+```toml
+[[outputs.file]]
+  ## Files to write to, "stdout" is a specially handled file.
+  files = ["stdout"]
+
+  ## Data format to output.
+  ## Each data format has it's own unique set of configuration options, read
+  ## more about them here:
+  ## https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_OUTPUT.md
+  data_format = "influx"
+
+  ## Additional configuration options go here
+```
+
+Each data_format has an additional set of configuration options available, which
+I'll go over below.
+
+# Influx:
+
+There are no additional configuration options for InfluxDB line-protocol. The
+metrics are serialized directly into InfluxDB line-protocol.
+
+### Influx Configuration:
+
+```toml
+[[outputs.file]]
+  ## Files to write to, "stdout" is a specially handled file.
+  files = ["stdout", "/tmp/metrics.out"]
+
+  ## Data format to output.
+  ## Each data format has it's own unique set of configuration options, read
+  ## more about them here:
+  ## https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_OUTPUT.md
+  data_format = "influx"
+```
+
+# Graphite:
+
+The Graphite data format translates Telegraf metrics into _dot_ buckets. A
+template can be specified for the output of Telegraf metrics into Graphite
+buckets. The default template is:
+
+```
+template = "host.tags.measurement.field"
+```
+
+In the above template, we have four parts:
+
+1. _host_ is a tag key. This can be any tag key that is in the Telegraf
+metric(s). If the key doesn't exist, it will be ignored. If it does exist, the
+tag value will be filled in.
+1. _tags_ is a special keyword that outputs all remaining tag values, separated
+by dots and in alphabetical order (by tag key). These will be filled after all
+tag keys are filled.
+1. _measurement_ is a special keyword that outputs the measurement name.
+1. _field_ is a special keyword that outputs the field name.
+
+Which means the following influx metric -> graphite conversion would happen:
+
+```
+cpu,cpu=cpu-total,dc=us-east-1,host=tars usage_idle=98.09,usage_user=0.89 1455320660004257758
+=>
+tars.cpu-total.us-east-1.cpu.usage_user 0.89 1455320690
+tars.cpu-total.us-east-1.cpu.usage_idle 98.09 1455320690
+```
+
+### Graphite Configuration:
+
+```toml
+[[outputs.file]]
+  ## Files to write to, "stdout" is a specially handled file.
+  files = ["stdout", "/tmp/metrics.out"]
+
+  ## Data format to output.
+  ## Each data format has it's own unique set of configuration options, read

+  data_format = "graphite"
+
+  # prefix each graphite bucket
+  prefix = "telegraf"
+  # graphite template
+  template = "host.tags.measurement.field"
+```
+
+# JSON:
+
+The JSON data format serialized Telegraf metrics in json format. The format is:
+
+```json
+{
+   "fields":{
+      "field_1":30,
+      "field_2":4,

+# Running Telegraf as a Windows Service
+
+Telegraf natively supports running as a Windows Service. Outlined below is are
+the general steps to set it up.
+
+1. Obtain the telegraf windows distribution
+2. Create the directory `C:\Program Files\Telegraf` (if you install in a different
+   location simply specify the `-config` parameter with the desired location)
+3. Place the telegraf.exe and the config file into `C:\Program Files\Telegraf`
+4. To install the service into the Windows Service Manager, run (as an
+   administrator):
+
+   ```
+   > C:\Program Files\Telegraf\telegraf.exe --service install
+   ```
+
+5. Edit the configuration file to meet your needs
+6. To check that it works, run:
+
+   ```
+   > C:\Program Files\Telegraf\telegraf.exe --config C:\Program Files\Telegraf\telegraf.conf --test
+   ```
+
+7. To start collecting data, run:
+
+   ```
+   > net start telegraf
+   ```
+
+## Other supported operations
+
+Telegraf can manage its own service through the --service flag:
+
+| Command                            | Effect                        |
+|------------------------------------|-------------------------------|
+| `telegraf.exe --service install`   | Install telegraf as a service |
+| `telegraf.exe --service uninstall` | Remove the telegraf service   |
+| `telegraf.exe --service start`     | Start the telegraf service    |
+| `telegraf.exe --service stop`      | Stop the telegraf service     |

+# Telegraf plugin: Cassandra
+
+#### Plugin arguments:
+- **context** string: Context root used for jolokia url
+- **servers** []string: List of servers with the format "<user:passwd@><host>:port"
+- **metrics** []string: List of Jmx paths that identify mbeans attributes
+
+#### Description
+
+The Cassandra plugin collects Cassandra/JVM metrics exposed as MBean's attributes through jolokia REST endpoint. All metrics are collected for each server configured.
+
+See: https://jolokia.org/ and [Cassandra Documentation](http://docs.datastax.com/en/cassandra/3.x/cassandra/operations/monitoringCassandraTOC.html)
+
+# Measurements:
+Cassandra plugin produces one or more measurements for each metric configured, adding Server's name  as `host` tag. More than one measurement is generated when querying table metrics with a wildcard for the keyspace or table name.
+
+Given a configuration like:
+
+```toml
+[[inputs.cassandra]]
+  context = "/jolokia/read"
+  servers = [":8778"]
+  metrics = ["/java.lang:type=Memory/HeapMemoryUsage"]
+```
+
+The collected metrics will be:
+
+```
+javaMemory,host=myHost,mname=HeapMemoryUsage HeapMemoryUsage_committed=1040187392,HeapMemoryUsage_init=1050673152,HeapMemoryUsage_max=1040187392,HeapMemoryUsage_used=368155000 1459551767230567084
+```
+
+# Useful Metrics:
+
+Here is a list of metrics that might be useful to monitor your cassandra cluster. This was put together from multiple sources on the web.

+# Ceph Storage Input Plugin
+
+Collects performance metrics from the MON and OSD nodes in a Ceph storage cluster.
+
+The plugin works by scanning the configured SocketDir for OSD and MON socket files.  When it finds
+a MON socket, it runs **ceph --admin-daemon $file perfcounters_dump**. For OSDs it runs **ceph --admin-daemon $file perf dump**
+
+The resulting JSON is parsed and grouped into collections, based on top-level key.  Top-level keys are
+used as collection tags, and all sub-keys are flattened. For example:
+
+```
+ {
+   "paxos": {
+     "refresh": 9363435,
+     "refresh_latency": {
+       "avgcount": 9363435,
+       "sum": 5378.794002000
+     }
+   }
+ }
+```
+
+Would be parsed into the following metrics, all of which would be tagged with collection=paxos:
+
+ - refresh = 9363435
+ - refresh_latency.avgcount: 9363435
+ - refresh_latency.sum: 5378.794002000
+
+
+### Configuration:
+
+```
+# Collects performance metrics from the MON and OSD nodes in a Ceph storage cluster.
+[[inputs.ceph]]
+  ## All configuration values are optional, defaults are shown below
+
+  ## location of ceph binary
+  ceph_binary = "/usr/bin/ceph"
+
+  ## directory in which to look for socket files
+  socket_dir = "/var/run/ceph"
+
+  ## prefix of MON and OSD socket files, used to determine socket type
+  mon_prefix = "ceph-mon"
+  osd_prefix = "ceph-osd"
+
+  ## suffix used to identify socket files
+  socket_suffix = "asok"
+```
+
+### Measurements & Fields:
+
+All fields are collected under the **ceph** measurement and stored as float64s. For a full list of fields, see the sample perf dumps in ceph_test.go.
+
+
+### Tags:
+
+All measurements will have the following tags:
+
+- type: either 'osd' or 'mon' to indicate which type of node was queried
+- id: a unique string identifier, parsed from the socket file name for the node
+- collection: the top-level key under which these fields were reported. Possible values are:
+  - for MON nodes:
+    - cluster
+    - leveldb
+    - mon
+    - paxos
+    - throttle-mon_client_bytes
+    - throttle-mon_daemon_bytes
+    - throttle-msgr_dispatch_throttler-mon
+  - for OSD nodes:
+    - WBThrottle
+    - filestore
+    - leveldb
+    - mutex-FileJournal::completions_lock
+    - mutex-FileJournal::finisher_lock
+    - mutex-FileJournal::write_lock
+    - mutex-FileJournal::writeq_lock
+    - mutex-JOS::ApplyManager::apply_lock
+    - mutex-JOS::ApplyManager::com_lock
+    - mutex-JOS::SubmitManager::lock
+    - mutex-WBThrottle::lock
+    - objecter
+    - osd
+    - recoverystate_perf
+    - throttle-filestore_bytes
+    - throttle-filestore_ops
+    - throttle-msgr_dispatch_throttler-client
+    - throttle-msgr_dispatch_throttler-cluster
+    - throttle-msgr_dispatch_throttler-hb_back_server
+    - throttle-msgr_dispatch_throttler-hb_front_serve
+    - throttle-msgr_dispatch_throttler-hbclient
+    - throttle-msgr_dispatch_throttler-ms_objecter
+    - throttle-objecter_bytes
+    - throttle-objecter_ops
+    - throttle-osd_client_bytes
+    - throttle-osd_client_messages

+# CGroup Input Plugin For Telegraf Agent
+
+This input plugin will capture specific statistics per cgroup.
+
+Following file formats are supported:
+
+* Single value
+
+```
+VAL\n
+```
+
+* New line separated values
+
+```
+VAL0\n
+VAL1\n
+```
+
+* Space separated values
+
+```
+VAL0 VAL1 ...\n
+```
+
+* New line separated key-space-value's
+
+```
+KEY0 VAL0\n
+KEY1 VAL1\n
+```
+
+
+### Tags:
+
+Measurements don't have any specific tags unless you define them at the telegraf level (defaults). We
+used to have the path listed as a tag, but to keep cardinality in check it's easier to move this 
+value to a field. Thanks @sebito91!
+
+
+### Configuration:
+
+```
+# [[inputs.cgroup]]
+  # paths = [
+  #   "/cgroup/memory",           # root cgroup
+  #   "/cgroup/memory/child1",    # container cgroup
+  #   "/cgroup/memory/child2/*",  # all children cgroups under child2, but not child2 itself
+  # ]
+  # files = ["memory.*usage*", "memory.limit_in_bytes"]
+
+# [[inputs.cgroup]]
+  # paths = [
+  #   "/cgroup/cpu",              # root cgroup
+  #   "/cgroup/cpu/*",            # all container cgroups
+  #   "/cgroup/cpu/*/*",          # all children cgroups under each container cgroup
+  # ]
+  # files = ["cpuacct.usage", "cpu.cfs_period_us", "cpu.cfs_quota_us"]
