If I had to clear up some space where's a good place to star

Hi Nagios,

If I had to clear up some space where's a good place to start?

Thanks,

Hi Maxwell,

The first thing I would check is the backups directory and remove any unwanted archives. By default, backups are stored in the following directory.

Code: Select all

/store/backups/nagiosxi

Also, check the log files. The following command will list the 10 largest files in /var/log.

Code: Select all

du -a /var/log | sort -n -r | head -n 10

Hi Nagios,

Thanks for the responses. It was actually the fact that I have almost 40GB of perfdata.

Is there a way to limit the amt of perfdata such that /usr/local/nagios/share/perfdata doesn't grow without bound?
Assuming I need to delete stuff. What happens if I start killing off rrd files? I assume the graphs will stop working. Will anything else castostrophic happen?

Thanks,
Max

Hi Max,

The RRD files contain a fixed number of data points to maintain the same size. You may need to increase the disk space on this server. However, you shouldn't need more than 100 GB for a large XI system. It's possible;e to change the settings for the RRD files but you will lose your historical data as the RRD's will need to be re-created.

There is also the possibility that your system has a number of inactive RRD"s consuming space. Follow the guide below to delete old RRD's. Please take a backup before making any changes.
