The Services/Graphics section gives a historical overview of a Wazo system’s activity based on snapshots recorded every 5 minutes. Graphics are available for the following resources :
- IRQ Stats
- System Load
- Memory Usage
- Open Files
- Open Inodes
- Swap Usage
Each section is presented as a series of 4 graphics : daily, weekly, monthly and yearly history. Each graphic can be clicked on to zoom. All information presented is read only.
- daily graphs are missing
- weekly/monthly/yearly graphs stop updating
- a mail is sent from cron every 5 minutes about a “bad magic number”
- the machine was forcefully stopped, while munin (responsible for the graphs) was running, resulting in a file corruption
Run the following command:
rm /var/lib/munin/htmlconf.storable /var/lib/munin/limits.storable
The graphs will be restored on the next run of munin, in the next 5 minutes.
