Warning

By executing this script you will lose all historical data explained above, the only way to restore the data is from a backup. It is advised that you create a backup before proceeding as per the Backing Up And Restoring Your Nagios XI System documentation.

 

 

Executing The Script

Establish a terminal session to your Nagios XI server as the root user and execute the following command:

/usr/local/nagiosxi/scripts/remove_historical_data.sh

 

You will first be warned and asked if you want to proceed:

========================
        WARNING!
========================

This script will remove ALL historical perfdata on your system. This action is permanent.
We recommend running the backup script before proceeding.

Do you want to continue? [Y/n]

 

Once you answer y the script will remove all the existing historical data, the output will be similar to:

Proceeding...
Stopping nagios: done.
Stopping ndo2db: done.
Removing historical data from disk...
Removing historical data in Nagios XI database...
Starting ndo2db: done.
Starting nagios: done.
Done.

 

After the script has completed Nagios XI will be operational again without all of the existing historical data.
