+
+## 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.
+

 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 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
-parts of the graphite bucket to combine into the measurement name. It can have a
-trailing `*` to indicate that the remainder of the metric should be used.
-Other words are considered tag keys. So the following template:
+incoming metrics. So the following template:
 
 ```toml
 templates = [
-    "region.measurement*"
+    "region.region.measurement*"
 ]
 ```
 
 would result in the following Graphite -> Telegraf transformation.
 
 ```
-us-west.cpu.load 100
-=> cpu.load,region=us-west value=100
+us.west.cpu.load 100
+=> cpu.load,region=us.west value=100
 ```
 
 #### Field Templates:
 
-There is also a _field_ keyword, which can only be specified once.
 The field keyword tells Telegraf to give the metric that field name.
 So the following template:
 
 ```toml
+separator = "_"
 templates = [
     "measurement.measurement.field.field.region"

+# 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

+# 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

 - 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:
+
+```

-
-#### Plugin arguments:
-- **servers** []string: list of one or more Elasticsearch servers
-- **local** boolean: If false, it will read the indices stats from all nodes
-- **cluster_health** boolean: If true, it will also obtain cluster level stats
-
-#### Description
+# Elasticsearch input plugin
 
 The [elasticsearch](https://www.elastic.co/) plugin queries endpoints to obtain
 [node](https://www.elastic.co/guide/en/elasticsearch/reference/current/cluster-nodes-stats.html)
 and optionally [cluster](https://www.elastic.co/guide/en/elasticsearch/reference/current/cluster-health.html) stats.
 
-Example:
+### Configuration:
 
 ```
-    [elasticsearch]
-
-    servers = ["http://localhost:9200"]
-
-    local = true
-
-    cluster_health = true
+[[inputs.elasticsearch]]

+# 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.

-
-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
+```
