Hello, @prakasha. You need to increase the disk space on the Nagios server by either cleaning up some log files or resizing the hard drive:

Here's is a useful command to show top 10 largest files on the system:

find / -type f -print0 | xargs -0 du | sort -n | tail -10 | cut -f2 | xargs -I{} du -sh {}

After you clean up some space I recommend updating the Fusion to the latest version and then lowering the "data retention period" under system settings:
