Aggregate zope munin graphs
Munin with munin.zope is a handy tool if you want to monitor your Zope instance. But it starts to be annoying when you have too many zeoclients and too many projects on one server. Using munin aggregate functionality you can create nice, human readable graphs reusing your existing data.
With the newest version of munin.zope you have 4 different plugins:
- ZServer threads
- ZODB activity
- Zope cache parameters
- Zope memory usage
Using aggregation you can end like this:
What it does? It takes data from multiple zeoclients (in this case every project from A-E have 4 zeoclients) and renders only total amount per project.
Here is munin.conf which does this trick:
[Server1;projectA]
address 127.0.0.1
[Server1;projectB]
address 127.0.0.2
[Server1;projectC]
address 127.0.0.3
[Server1;projectD]
address 127.0.0.4
[Server1;projectE]
address 127.0.0.5
[Server1;Aggregated]
