The SD Card on my Raspberry Pi died this week. So I decided that this time, I’d use Salt to manage my Pi and not have to worry about backing up my configuration from the Pi itself as Salt would be managing it for me!

I recently bought a Telstra Prepaid (ZTE MF823) 4G stick to use while I’m out and about. It works great for internet, getting a nice 20Mbits in some locations, but I’ve run into some issues with the IP addressing scheme of the stick’s network.

I recently found out that Telstra has a SMS API, and for now, it’s free to use for up to 1000 SMSes a month for Australians (sorry rest of the world).

In the previous post, I got the Raspberry Pi outputting the values from the temperature sensors via SNMP.

In this post, I’ll be configuring Zabbix to monitor and record these values so that I can see how cold it was last night.
You’ll need to note down the OIDs that were configured on the SNMP agent in the last post so you can use them in this post.

Monitoring the Pi

Adding it in

The Raspberry Pi will need to be monitored in some way by Zabbix in order for us to record the temperatures from the SNMP agent that we’ve set up.
You’ll need to add the Raspberry Pi as a host in Zabbix, and give it an IP address under the SNMP interfaces section. I’ve added the SNMP OS Linux template to monitor the rest of the Pi stats, but that’s not required for monitoring temperatures.
