+
+## v1.0 beta 1 [2016-06-07]
+
+### Release Notes
+
+- `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`.
+
+- All AWS plugins now utilize a standard mechanism for evaluating credentials.
+This allows all AWS plugins to support environment variables, shared credential
+files & profiles, and role assumptions. See the specific plugin README for
+details.
+
+- The AWS CloudWatch input plugin can now declare a wildcard value for a metric
+dimension. This causes the plugin to read all metrics that contain the specified
+dimension key regardless of value. This is used to export collections of metrics
+without having to know the dimension values ahead of time.
+
+- The AWS CloudWatch input plugin can now be configured with the `cache_ttl`
+attribute. This configures the TTL of the internal metric cache. This is useful
+in conjunction with wildcard dimension values as it will control the amount of
+time before a new metric is included by the plugin.
+

 # Graphite:

 The Graphite data format translates graphite _dot_ buckets directly into
-telegraf measurement names, with a single value field, and without any tags. For
-more advanced options, Telegraf supports specifying "templates" to translate
+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.

-#### Separator:
-
-You can specify a separator to use for the parsed metrics.
-By default, it will leave the metrics with a "." separator.
-Setting `separator = "_"` will translate:
+Templates are of the form:

 ```
-cpu.usage.idle 99
-=> cpu_usage_idle value=99
+"host.mytag.mytag.measurement.measurement.field*"
 ```

-#### Measurement/Tag Templates:
+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. _measurement_ is a special keyword that tells Telegraf which

+# 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

+# chrony Input Plugin
+
+Get standard chrony metrics, requires chronyc executable.
+
+Below is the documentation of the various headers returned by `chronyc tracking`.
+
+- Reference ID - This is the refid and name (or IP address) if available, of the
+server to which the computer is currently synchronised. If this is 127.127.1.1
+it means the computer is not synchronised to any external source and that you
+have the ‘local’ mode operating (via the local command in chronyc (see section local),
+or the local directive in the ‘/etc/chrony.conf’ file (see section local)).
+- Stratum - The stratum indicates how many hops away from a computer with an attached
+reference clock we are. Such a computer is a stratum-1 computer, so the computer in the
+example is two hops away (i.e. a.b.c is a stratum-2 and is synchronised from a stratum-1).
+- Ref time - This is the time (UTC) at which the last measurement from the reference
+source was processed.
+- System time - In normal operation, chronyd never steps the system clock, because any
+jump in the timescale can have adverse consequences for certain application programs.
+Instead, any error in the system clock is corrected by slightly speeding up or slowing
+down the system clock until the error has been removed, and then returning to the system
+clock’s normal speed. A consequence of this is that there will be a period when the
+system clock (as read by other programs using the gettimeofday() system call, or by the
+date command in the shell) will be different from chronyd's estimate of the current true
+time (which it reports to NTP clients when it is operating in server mode). The value
+reported on this line is the difference due to this effect.
+- Last offset - This is the estimated local offset on the last clock update.
+- RMS offset - This is a long-term average of the offset value.
+- Frequency - The ‘frequency’ is the rate by which the system’s clock would be
+wrong if chronyd was not correcting it. It is expressed in ppm (parts per million).
+For example, a value of 1ppm would mean that when the system’s clock thinks it has
+advanced 1 second, it has actually advanced by 1.000001 seconds relative to true time.
+- Residual freq - This shows the ‘residual frequency’ for the currently selected
+reference source. This reflects any difference between what the measurements from the
+reference source indicate the frequency should be and the frequency currently being used.
+The reason this is not always zero is that a smoothing procedure is applied to the
+frequency. Each time a measurement from the reference source is obtained and a new
+residual frequency computed, the estimated accuracy of this residual is compared with the
+estimated accuracy (see ‘skew’ next) of the existing frequency value. A weighted average
+is computed for the new frequency, with weights depending on these accuracies. If the
+measurements from the reference source follow a consistent trend, the residual will be
+driven to zero over time.
+- Skew - This is the estimated error bound on the frequency.
+- Root delay - This is the total of the network path delays to the stratum-1 computer
+from which the computer is ultimately synchronised. In certain extreme situations, this
+value can be negative. (This can arise in a symmetric peer arrangement where the computers’
+frequencies are not tracking each other and the network delay is very short relative to the
+turn-around time at each computer.)
+- Root dispersion - This is the total dispersion accumulated through all the computers
+back to the stratum-1 computer from which the computer is ultimately synchronised.
+Dispersion is due to system clock resolution, statistical measurement variations etc.
+- Leap status - This is the leap status, which can be Normal, Insert second,
+Delete second or Not synchronised.
+
+### Configuration:
+
+```toml
+# Get standard chrony metrics, requires chronyc executable.
+[[inputs.chrony]]
+  ## If true, chronyc tries to perform a DNS lookup for the time server.
+  # dns_lookup = false
+```
+
+### Measurements & Fields:
+
+- chrony
+    - last_offset (float, seconds)
+    - rms_offset (float, seconds)
+    - frequency (float, ppm)
+    - residual_freq (float, ppm)
+    - skew (float, ppm)
+    - root_delay (float, seconds)
+    - root_dispersion (float, seconds)
+    - update_interval (float, seconds)
+
+### Tags:
+
+- All measurements have the following tags:
+    - reference_id
+    - stratum
+    - leap_status
+
+### Example Output:
+
+```
+$ telegraf -config telegraf.conf -input-filter chrony -test
+* Plugin: chrony, Collection 1

 - `dimensions` must be valid CloudWatch [Dimension](http://docs.aws.amazon.com/AmazonCloudWatch/latest/DeveloperGuide/cloudwatch_concepts.html#Dimension) name/value pairs

+Omitting or specifying a value of `'*'` for a dimension value configures all available metrics that contain a dimension with the specified name
+to be retrieved. If specifying >1 dimension, then the metric must contain *all* the configured dimensions where the the value of the
+wildcard dimension is ignored.
+
+Example:
+```

+
+  ## Dimension filters for Metric (optional)

+- name: `q-example`, availabilityZone: `us-east-1a`
+- name: `q-example`, availabilityZone: `us-east-1b`

+
+Then 2 metrics will be output:
+- name: `p-example`, availabilityZone: `us-east-1a`
+- name: `p-example`, availabilityZone: `us-east-1b`
+
+If the `AvailabilityZone` wildcard dimension was omitted, then a single metric (name: `p-example`)
+would be exported containing the aggregate values of the ELB across availability zones.
+
 #### Restrictions and Limitations
 - CloudWatch metrics are not available instantly via the CloudWatch API. You should adjust your collection `delay` to account for this lag in metrics availability based on your [monitoring subscription level](http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/using-cloudwatch-new.html)
 - CloudWatch API usage incurs cost - see [GetMetricStatistics Pricing](https://aws.amazon.com/cloudwatch/pricing/)

+# Conntrack Plugin
+
+Collects stats from Netfilter's conntrack-tools.
+
+The conntrack-tools provide a mechanism for tracking various aspects of
+network connections as they are processed by netfilter. At runtime, 
+conntrack exposes many of those connection statistics within /proc/sys/net.
+Depending on your kernel version, these files can be found in either
+/proc/sys/net/ipv4/netfilter or /proc/sys/net/netfilter and will be
+prefixed with either ip_ or nf_.  This plugin reads the files specified 
+in its configuration and publishes each one as a field, with the prefix
+normalized to ip_.  
+
+In order to simplify configuration in a heterogeneous environment, a superset
+of directory and filenames can be specified.  Any locations that don't exist
+will be ignored.
+
+For more information on conntrack-tools, see the 
+[Netfilter Documentation](http://conntrack-tools.netfilter.org/).
+
+
+### Configuration:
+
+```toml
+ # Collects conntrack stats from the configured directories and files.
+ [[inputs.conntrack]]
+   ## The following defaults would work with multiple versions of conntrack.
+   ## Note the nf_ and ip_ filename prefixes are mutually exclusive across
+   ## kernel versions, as are the directory locations.
+
+   ## Superset of filenames to look for within the conntrack dirs.
+   ## Missing files will be ignored.
+   files = ["ip_conntrack_count","ip_conntrack_max",
+            "nf_conntrack_count","nf_conntrack_max"]
+
+   ## Directories to search within for the conntrack files above.
+   ## Missing directrories will be ignored.
+   dirs = ["/proc/sys/net/ipv4/netfilter","/proc/sys/net/netfilter"]
+```
+
+### Measurements & Fields:
+
+- conntrack
+    - ip_conntrack_count (int, count): the number of entries in the conntrack table 
+    - ip_conntrack_max (int, size): the max capacity of the conntrack table
+
+### Tags:
+
+This input does not use tags.
+
+### Example Output:
+
+```
+$ ./telegraf -config telegraf.conf -input-filter conntrack -test
+conntrack,host=myhost ip_conntrack_count=2,ip_conntrack_max=262144 1461620427667995735

+# GrayLog plugin
+
+The Graylog plugin can collect data from remote Graylog service URLs.
+
+Plugin currently support two type of end points:-
+
+- multiple  (Ex http://[graylog-server-ip]:12900/system/metrics/multiple)
+- namespace (Ex http://[graylog-server-ip]:12900/system/metrics/namespace/{namespace})
+
+End Point can be a mixe of one  multiple end point  and several namespaces end points
+
+
+Note: if namespace end point specified metrics array will be ignored for that call.
+
+### Configuration:
+
+```toml
+# Read flattened metrics from one or more GrayLog HTTP endpoints
+[[inputs.graylog]]
+  ## API endpoint, currently supported API:
+  ##
+  ##   - multiple  (Ex http://<host>:12900/system/metrics/multiple)
+  ##   - namespace (Ex http://<host>:12900/system/metrics/namespace/{namespace})
+  ##
+  ## For namespace endpoint, the metrics array will be ignored for that call.
+  ## Endpoint can contain namespace and multiple type calls.
+  ##
+  ## Please check http://[graylog-server-ip]:12900/api-browser for full list
+  ## of endpoints
+  servers = [
+    "http://[graylog-server-ip]:12900/system/metrics/multiple",

+
+  ## Metrics list
+  ## List of metrics can be found on Graylog webservice documentation.
+  ## Or by hitting the the web service api at:
+  ##   http://[graylog-host]:12900/system/metrics
+  metrics = [
+    "jvm.cl.loaded",
+    "jvm.memory.pools.Metaspace.committed"

-
-There are two important details to note about the collected metrics:
-
-1. Even though the values in JSON are being displayed as integers,
-the metrics are reported as floats.
-JSON encoders usually don't print the fractional part for round floats.
-Because you cannot change the type of an existing field in InfluxDB,
-we assume all numbers are floats.
-
-2. The top-level keys' names (in the example above, `"k1"`, `"k2"`, and `"k3"`)
-are not considered when recording the metrics.

+# logparser Input Plugin
+
+The logparser plugin streams and parses the given logfiles. Currently it only
+has the capability of parsing "grok" patterns from logfiles, which also supports
+regex patterns.
+
+### Configuration:
+
+```toml
+[[inputs.logparser]]
+  ## Log files to parse.
+  ## These accept standard unix glob matching rules, but with the addition of
+  ## ** as a "super asterisk". ie:
+  ##   /var/log/**.log     -> recursively find all .log files in /var/log
+  ##   /var/log/*/*.log    -> find all .log files with a parent dir in /var/log
+  ##   /var/log/apache.log -> only tail the apache log file
+  files = ["/var/log/influxdb/influxdb.log"]
+  ## Read file from beginning.
+  from_beginning = false
+
+  ## Parse logstash-style "grok" patterns:
+  ##   Telegraf builtin parsing patterns: https://goo.gl/dkay10
+  [inputs.logparser.grok]
+    ## This is a list of patterns to check the given log file(s) for.
+    ## Note that adding patterns here increases processing time. The most
+    ## efficient configuration is to have one file & pattern per logparser.
+    patterns = ["%{INFLUXDB_HTTPD_LOG}"]
+    ## Full path(s) to custom pattern files.
+    custom_pattern_files = []
+    ## Custom patterns can also be defined here. Put one pattern per line.
+    custom_patterns = '''
+    '''
+```
+
+## Grok Parser
+
+The grok parser uses a slightly modified version of logstash "grok" patterns,
+with the format `%{<capture_syntax>[:<semantic_name>][:<modifier>]}`
+
+
+Telegraf has many of it's own
+[built-in patterns](https://github.com/influxdata/telegraf/blob/master/plugins/inputs/logparser/grok/patterns/influx-patterns),
+as well as supporting
+[logstash's builtin patterns](https://github.com/logstash-plugins/logstash-patterns-core/blob/master/patterns/grok-patterns).
+
+
+The best way to get acquainted with grok patterns is to read the logstash docs,
+which are available here:
+  https://www.elastic.co/guide/en/logstash/current/plugins-filters-grok.html
+
+
+If you need help building patterns to match your logs,
+you will find the http://grokdebug.herokuapp.com application quite useful!
+
+
+By default all named captures are converted into string fields.
+Modifiers can be used to convert captures to other types or tags.
+Timestamp modifiers can be used to convert captures to the timestamp of the
+ parsed metric.
+
+
+- Available modifiers:
+  - string   (default if nothing is specified)
+  - int
+  - float
+  - duration (ie, 5.23ms gets converted to int nanoseconds)
+  - tag      (converts the field into a tag)
+  - drop     (drops the field completely)
+- Timestamp modifiers:
+  - ts-ansic         ("Mon Jan _2 15:04:05 2006")
+  - ts-unix          ("Mon Jan _2 15:04:05 MST 2006")
+  - ts-ruby          ("Mon Jan 02 15:04:05 -0700 2006")
+  - ts-rfc822        ("02 Jan 06 15:04 MST")
+  - ts-rfc822z       ("02 Jan 06 15:04 -0700")
+  - ts-rfc850        ("Monday, 02-Jan-06 15:04:05 MST")
+  - ts-rfc1123       ("Mon, 02 Jan 2006 15:04:05 MST")
+  - ts-rfc1123z      ("Mon, 02 Jan 2006 15:04:05 -0700")
+  - ts-rfc3339       ("2006-01-02T15:04:05Z07:00")
+  - ts-rfc3339nano   ("2006-01-02T15:04:05.999999999Z07:00")
+  - ts-httpd         ("02/Jan/2006:15:04:05 -0700")
+  - ts-epoch         (seconds since unix epoch)
+  - ts-epochnano     (nanoseconds since unix epoch)
+  - ts-"CUSTOM"
+
+
+CUSTOM time layouts must be within quotes and be the representation of the
+"reference time", which is `Mon Jan 2 15:04:05 -0700 MST 2006`
+See https://golang.org/pkg/time/#Parse for more details.

+## Nstat input plugin
+
+Plugin collects network metrics from `/proc/net/netstat`, `/proc/net/snmp` and `/proc/net/snmp6` files
+
+### Configuration
+
+The plugin firstly tries to read file paths from config values
+if it is empty, then it reads from env variables.
+* `PROC_NET_NETSTAT`
+* `PROC_NET_SNMP`
+* `PROC_NET_SNMP6`
+
+If these variables are also not set,
+then it tries to read the proc root from env - `PROC_ROOT`,
+and sets `/proc` as a root path if `PROC_ROOT` is also empty.
+
+Then appends default file paths:
+* `/net/netstat`
+* `/net/snmp`
+* `/net/snmp6`
+
+So if nothing is given, no paths in config and in env vars, the plugin takes the default paths.
+* `/proc/net/netstat`
+* `/proc/net/snmp`
+* `/proc/net/snmp6`
+
+The sample config file
+```toml
+[[inputs.nstat]]
+  ## file paths
+  ## e.g: /proc/net/netstat, /proc/net/snmp, /proc/net/snmp6
+  # proc_net_netstat    = 	""
+  # proc_net_snmp 		= 	""
+  # proc_net_snmp6 		= 	""
+  ## dump metrics with 0 values too
+  # dump_zeros			= 	true
+```

+# rollbar_webhooks
+
+This is a Telegraf service plugin that listens for events kicked off by Rollbar Webhooks service and persists data from them into configured outputs. To set up the listener first generate the proper configuration:
+```sh
+$ telegraf -sample-config -input-filter rollbar_webhooks -output-filter influxdb > config.conf.new
+```
+Change the config file to point to the InfluxDB server you are using and adjust the settings to match your environment. Once that is complete:
+```sh
+$ cp config.conf.new /etc/telegraf/telegraf.conf
+$ sudo service telegraf start
+```
+Once the server is running you should configure your Rollbar's Webhooks to point at the `rollbar_webhooks` service. To do this go to `rollbar.com/` and click `Settings > Notifications > Webhook`. In the resulting page set `URL` to `http://<my_ip>:1619`, and click on `Enable Webhook Integration`.
+
+## Events
+
+The titles of the following sections are links to the full payloads and details for each event. The body contains what information from the event is persisted. The format is as follows:
+```
+# TAGS
+* 'tagKey' = `tagValue` type
+# FIELDS
+* 'fieldKey' = `fieldValue` type
+```
+The tag values and field values show the place on the incoming JSON object where the data is sourced from.
+
+See [webhook doc](https://rollbar.com/docs/webhooks/)
+
+#### `new_item` event
+
+**Tags:**
+* 'event' = `event.event_name` string

Cameron Sparr	4f5d5926d9	Set a timeout for calls to input.Gather Changing the internal behavior around running plugins. Each plugin will now have it's own goroutine with it's own ticker. This means that a hung plugin will not block any other plugins. When a plugin is hung, we will log an error message every interval, letting users know which plugin is hung. Currently the input interface does not have any methods for killing a running Gather call, so there is nothing we can do but log an "ERROR" and move on. This will give some visibility into the plugin that is acting up. closes #1230 fixes #479	2016-05-21 21:39:01 +01:00
