Nagios XI - Mass Delete Old RRD Files

Mass Delete Old RRD Files

This KB article will show you how to run a script to delete all RRDs (and their respective XML files) under /usr/local/nagios/share/perfdata that have not been written to in 5 days, that also includes hosts/services that have been DOWN for more than 5 days, please be aware of that limitation.

Steps

Establish a terminal session to your Nagios XI server as the root user.

Execute the following commands:

cd /tmp
wget https://assets.nagios.com/downloads/nagiosxi/scripts/delete_old_rrds.sh
sh delete_old_rrds.sh 

You will be prompted to confirm that you want to proceed. Once you answer yes the script will output all the files it deletes onto the screen. If you are using an SSH terminal session through a program like Putty you may need to increase your output buffer to see all of the results as there may be a lot of output.
