 ### Release Notes

+- 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

 # 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

+### Required parameters:
+
+* `brokers`: List of strings, this is for speaking to a cluster of `kafka` brokers. On each flush interval, Telegraf will randomly choose one of the urls to write to. Each URL should just include host and port e.g. -> `["{host}:{port}","{host2}:{port2}"]`
+* `topic`: The `kafka` topic to publish to.
+
+
+### Optional parameters:
+
+* `routing_tag`:  if this tag exists, it's value will be used as the routing key
+* `compression_codec`: What level of compression to use: `0` -> no compression, `1` -> gzip compression, `2` -> snappy compression
+* `required_acks`: a setting for how may `acks` required from the `kafka` broker cluster.
+* `max_retry`: Max number of times to retry failed write
+* `ssl_ca`: SSL CA
+* `ssl_cert`: SSL CERT
+* `ssl_key`: SSL key
+* `insecure_skip_verify`: Use SSL but skip chain & host verification (default: false)
+* `data_format`: [About Telegraf data formats](https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_OUTPUT.md)
