+**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 its 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.
+
 **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

-### 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.

 # 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.
 
-**NSSM** (the Non-Sucking Service Manager) is a tool that helps you in a 
+1. Obtain the telegraf windows distribution
-[number of scenarios](http://nssm.cc/scenarios) including running Go binaries
+2. Create the directory `C:\Program Files\Telegraf` (if you install in a different
-that were not specifically designed to run only in Windows platforms.
+   location simply specify the `-config` parameter with the desired location)
+3. Place the telegraf.exe and the telegraf.conf config file into `C:\Program Files\Telegraf`
+4. To install the service into the Windows Service Manager, run the following in PowerShell as an administrator (If necessary, you can wrap any spaces in the file paths in double quotes ""):
 
-## NSSM Installation via Chocolatey
+   ```
+   > C:\"Program Files"\Telegraf\telegraf.exe --service install
+   ```
 
-You can install [Chocolatey](https://chocolatey.org/) and [NSSM](http://nssm.cc/) 
+5. Edit the configuration file to meet your needs
-with these commands
+6. To check that it works, run:
 
-```powershell
+   ```
-iex ((new-object net.webclient).DownloadString('https://chocolatey.org/install.ps1'))
+   > C:\"Program Files"\Telegraf\telegraf.exe --config C:\"Program Files"\Telegraf\telegraf.conf --test
-choco install -y nssm
+   ```
-```
 
-## 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 
+## Other supported operations
-**telegraf.conf** sample to allocate the metrics you want to send to **InfluxDB**.
 
-Once you have NSSM installed in your system, the process is quite straightforward.
+Telegraf can manage its own service through the --service flag:
-You only need to type this command in your Windows shell
 
-```powershell
+| Command                            | Effect                        |
-nssm install Telegraf c:\telegraf\telegraf.exe -config c:\telegraf\telegraf.config
+|------------------------------------|-------------------------------|
-```
+| `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

+# HTTP listener service input plugin
+
+The HTTP listener is a service input plugin that listens for messages sent via HTTP POST.
+The plugin expects messages in the InfluxDB line-protocol ONLY, other Telegraf input data formats are not supported.
+The intent of the plugin is to allow Telegraf to serve as a proxy/router for the /write endpoint of the InfluxDB HTTP API.
+When chaining Telegraf instances using this plugin, CREATE DATABASE requests receive a 200 OK response with message body `{"results":[]}` but they are not relayed. The output configuration of the Telegraf instance which ultimately submits data to InfluxDB determines the destination database.
+
+See: [Telegraf Input Data Formats](https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_INPUT.md#influx).
+Example:  curl -i -XPOST 'http://localhost:8186/write' --data-binary 'cpu_load_short,host=server01,region=us-west value=0.64 1434055562000000000'
+
+### Configuration:
+
+This is a sample configuration for the plugin.
+
+```toml
+# # Influx HTTP write listener
+[[inputs.http_listener]]

+  service_address = ":8186"

+# Iptables Plugin
+
+The iptables plugin gathers packets and bytes counters for rules within a set of table and chain from the Linux's iptables firewall.
+
+Rules are identified through associated comment. Rules without comment are ignored.
+
+The iptables command requires CAP_NET_ADMIN and CAP_NET_RAW capabilities. You have several options to grant telegraf to run iptables:
+
+* Run telegraf as root. This is strongly discouraged.
+* Configure systemd to run telegraf with CAP_NET_ADMIN and CAP_NET_RAW. This is the simplest and recommended option.
+* Configure sudo to grant telegraf to run iptables. This is the most restrictive option, but require sudo setup.
+
+### Using systemd capabilities
+
+You may run `systemctl edit telegraf.service` and add the following:
+
+```
+[Service]
+CapabilityBoundingSet=CAP_NET_RAW CAP_NET_ADMIN
+AmbientCapabilities=CAP_NET_RAW CAP_NET_ADMIN
+```
+
+Since telegraf will fork a process to run iptables, `AmbientCapabilities` is required to transmit the capabilities bounding set to the forked process.
+
+### Using sudo
+
+You may edit your sudo configuration with the following:
+
+```sudo
+telegraf ALL=(root) NOPASSWD: /usr/bin/iptables -nvL *
+```
+
+### Configuration:
+
+```toml
+  # use sudo to run iptables
+  use_sudo = false
+  # defines the table to monitor:
+  table = "filter"
+  # defines the chains to monitor:
+  chains = [ "INPUT" ]
+```
+
+### Measurements & Fields:
+
+
+- iptables
+    - pkts (integer, count)
+    - bytes (integer, bytes)
+
+### Tags:
+
+- All measurements have the following tags:
+    - table
+    - chain
+    - ruleid
+
+The `ruleid` is the comment associated to the rule.
+
+### Example Output:
+
+```
+$ iptables -nvL INPUT
+Chain INPUT (policy DROP 0 packets, 0 bytes)
+pkts bytes target     prot opt in     out     source               destination
+100   1024   ACCEPT     tcp  --  *      *       192.168.0.0/24       0.0.0.0/0            tcp dpt:22 /* ssh */
+ 42   2048   ACCEPT     tcp  --  *      *       192.168.0.0/24       0.0.0.0/0            tcp dpt:80 /* httpd */
+```
+
+```
+$ ./telegraf -config telegraf.conf -input-filter iptables -test
+iptables,table=filter,chain=INPUT,ruleid=ssh pkts=100i,bytes=1024i 1453831884664956455

+By default this plugin is not configured to gather metrics from mesos. Since a mesos cluster can be deployed in numerous ways it does not provide any default
+values. User needs to specify master/slave nodes this plugin will gather metrics from. Additionally, enabling `slave_tasks` will allow
+gathering metrics from tasks running on specified slaves (this option is disabled by default).
