+## 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`.

 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
-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.

+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.

 # Running Telegraf as a Windows Service

-If you have tried to install Go binaries as Windows Services with the **sc.exe**
-tool you may have seen that the service errors and stops running after a while.
+Telegraf natively supports running as a Windows Service. Outlined below is are
+the general steps to set it up.

-**NSSM** (the Non-Sucking Service Manager) is a tool that helps you in a 
-[number of scenarios](http://nssm.cc/scenarios) including running Go binaries
-that were not specifically designed to run only in Windows platforms.
+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):

-## NSSM Installation via Chocolatey
+   ```
+   > C:\Program Files\Telegraf\telegraf.exe --service install
+   ```

-You can install [Chocolatey](https://chocolatey.org/) and [NSSM](http://nssm.cc/) 
-with these commands
+5. Edit the configuration file to meet your needs
+6. To check that it works, run:

-```powershell
-iex ((new-object net.webclient).DownloadString('https://chocolatey.org/install.ps1'))
-choco install -y nssm
-```
+   ```
+   > C:\Program Files\Telegraf\telegraf.exe --config C:\Program Files\Telegraf\telegraf.conf --test
+   ```

-## Installing Telegraf as a Windows Service with NSSM
+7. To start collecting data, run:

-You can download the latest Telegraf Windows binaries (still Experimental at 
-the moment) from [the Telegraf Github repo](https://github.com/influxdata/telegraf).
+   ```
+   > net start telegraf
+   ```

-Then you can create a C:\telegraf folder, unzip the binary there and modify the 
-**telegraf.conf** sample to allocate the metrics you want to send to **InfluxDB**.
+## Other supported operations

-Once you have NSSM installed in your system, the process is quite straightforward.
-You only need to type this command in your Windows shell
+Telegraf can manage its own service through the --service flag:

-```powershell
-nssm install Telegraf c:\telegraf\telegraf.exe -config c:\telegraf\telegraf.config
-```
+| 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     |

-And now your service will be installed in Windows and you will be able to start and
-stop it gracefully

+# 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"]

+- Reference ID - This is the refid and name (or IP address) if available, of the

+- 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.

 - `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:
+```
+[[inputs.cloudwatch.metrics]]

+
+  ## Dimension filters for Metric (optional)
+  [[inputs.cloudwatch.metrics.dimensions]]

+- 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

-# Elasticsearch plugin
-
-#### 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]
+[[inputs.elasticsearch]]
+  servers = ["http://localhost:9200"]
+  local = true
+  cluster_health = true

-    servers = ["http://localhost:9200"]
-
-    local = true
-
-    cluster_health = true
+  ## Optional SSL Config
+  # ssl_ca = "/etc/telegraf/ca.pem"
+  # ssl_cert = "/etc/telegraf/cert.pem"
+  # ssl_key = "/etc/telegraf/key.pem"
+  ## Use SSL but skip chain & host verification
+  # insecure_skip_verify = false
 ```
