Zabbix - Monitoring
Well, it’s been a long time, but here is another blog post from my side.
Today I am going to talk about Zabbix, it’s a pretty great monitoring Application that is easy enough to install and get running. I am not sure regarding security when it is openly accessible, so if you need that do your research first!
How it works
The basic setup is simple, it’s a glorified key-value storage. You basically just create ‘Hosts’ that are then polled for data. This data is saved for the configured time (usually a year) and can be displayed in various forms (including your standard gnuplot graphs).
This data is then continously analyzed and matched against ‘Triggers’. Triggers themselves are simple equations that get triggered should the expression be true. This can be anything, from a hard coded limit, to a sudden jump in values (for example CPU usage jumping without a reason).
Why I think it is worth to use it in simple situations at least
It is easy to setup (just a few commands on Centos 7), it is rather quick (although not pretty), and it works which is an important property.
