One of the things I like to have in my lab environment is the ability to monitoring all OSes and keep an eye on such things as temperatures, disk space, and other sensors. I was disheartened to find that UnRAID 6 did not have SNMP installed or configured. After some searching I was able to figure out how to get SNMP installed.
First, Log into your UnRAID Web page and Click on Plugins
Next copy and paste the NerdPack Plugin into the URL Field and Click Install. The NerdPack installs the prerequisites that you need to install SNMP. Then you will see a plugin window pop up.
Then we go and reboot the server. This step is not necessary, but I prefer to do this after each plugin install.
Next go to Settings, and Nerd Pack
Find the entry for Perl and click the slider
Click Apply on the bottom
The package manager will launch a window and you see the package install.
Then we go and install the UnRaid SNMP Plugin following the same steps for the previous plugin install.
Login to the host via SSH console and verify that SNMP is working by executing
snmpwalk -v2c -c public localhost
You should see output similar to below.
Now you should be able to import your host into an SNMPD Based monitoring.
