#FreeNAS app for Splunk

This repo contains a FreeNAS app for Splunk®

##FreeNAS

http://www.freenas.org/

FreeNAS is a powerful, flexible home storage system – configured by you, for your needs.

Note - This should also work for a vanilla FreeBSD host, and FreeNAS 10 but only basic testing done

###ZFS The Z File System, or ZFS , is an advanced file system designed to overcome many of the major problems found in previous designs.

##Splunk®

Free Splunk Download Link

Splunk Enterprise is the leading platform for real-time operational intelligence. When you download Splunk Enterprise for free, you get a Splunk Enterprise license for 60 days that lets you index up to 500 megabytes of data per day.

When the free trial ends, you can convert to a perpetual Free license or purchase an Enterprise license to continue using the expanded functionality designed for multi-user deployments.

##Dashboards

###System Info

This Dashboard contains information on the FreeNAS system(s)

##Inputs

For this app to work completely the REST API Modular Input is required, install the REST app first (thanks to the awesome Damien Dallimore)

###FreeNAS API

http://api.freenas.org/index.html

This app utilises the FreeNAS api for some data.

Check either inputs.conf, or if you are a novice you can just change the details in the “data inputs” section of Splunk.

You will need to configure for your environment;

• Your FreeNAS IP address or host name
• Your FreeNAS ROOT password (currently the FreeNAS API only allows the root user)

###.SH files There are several .sh scripts in /TA-SH_files_for_FreeNAS directory that need to be placed on a persistent dataset on the FreeNAS server with a cron job associated with them, set to run every few minutes.

https://doc.freenas.org/9.3/freenas_tasks.html

these scripts output to “logger” - which is the syslog output

Also once copied over this command may be your friend :)

chmod 777 foo.sh

###Syslog

You need to configure FreeNAS to log to a central server (Splunk®) for the data to be ingested, point to port 1514 e.g.

192.168.1.2:1514

###Local Weather input - REST api (Optional)

To compare local temps with system temps I added a json API input via openweathermap

Its free to signup - edit inputs.conf with your location information and appid (API key)

##VERY IMPORTANT NOTE

This app is work in progress

Please submit issues, improvements patches to github - http://j-c-b.github.io/freenas_splunk/

App is available directly on Splunkbase https://splunkbase.splunk.com/app/2940/#/overview

##TODO

• Snapshot script and dashboard for success / fail
• ZFS related goodness for pools and datasets
• Improve dashboard search efficiency
• Use ipmiOutput for host data input
