[Check_mk (english)] Is diskspace cleanup configuration for pnp4nagios in 1.5.0 incorrect?

MikeL · November 8, 2019, 2:02pm

It appears that there is a diskspace cleanup plug-in for pnp4nagios at:

~/share/diskspace/pnp4nagios

cleanup_paths = [
'var/pnp4nagios/perfdata/*/*.rrd',
'var/pnp4nagios/perfdata/*/*.xml',
]

I believe this results in pnp4nagios rrd files being removed if they are older than "maxfile age" in the diskspace cleanup configuration.

The cleanup of rrd files for abandoned hosts seems to be handled by the diskspace cleanup script.

Would it be appropriate to:

rm ~/share/diskspace/pnp4nagios ?

Thanks, Michael

Hi Michael,

What is wrong with the deletion of the “maxfile age” files?

This is the “recommended” behavior to remove old PNP4Nagios files.

Attention if you remove the diskspace file, it is removed from all sites using the same CMK version on this server.

Best regards

Andreas

Hi Andreas,

Thanks for that. I thought diskspace was deleting files based on the file creation time rather than modification time.

I now see that it is using modification time which should be fine for rrd files.

Thanks for your help.
