Automatic execution
You do not have to configure the execution of this manually, ; every Checkmk instance user has a cronjob for the diskspace feature, which gets executed 5 minutes after each hour.
Which files are handled?
When started manually or automatically by a cronjob, the diskspace command behaves like this:
- read in configuration (set in global settings)
- load plugins from ~/share/diskspace
- load custom plugins from ~/local/share/diskspace, if existant existent - yes, you can define additional plugins yourselves
- collect paths and time information of all paths defines defined in loaded plugins
- delete files according to configured settings
...
| that "Cleanup abandoned host files older than" only handles completely missing hosts, not specific missing services, whereas the other two settings would also remove left service files. |
