Has anyone found a decent way out there to monitor GlusterFS volumes? I'm currently using Nagios and Cacti to take care of basic CPU, Load, Memory, and raw Disk I/O. I need to monitor GlusterFS status and making sure all volumes are available.. My test environment is 6 servers with 6 AFR volumes which are each shared between those 2 servers. All volumes are mounted on each server. The checks I'm testing out so far include a simple Bash script that writes the current Unix timestamp and hostname to a file once a minute. This is done by each server on only the volumes that they store. echo "$(uname -n):$(date +%s)" > /mnt/gluster01/CHECK_FILE The Nagios NRPE daemon would then execute a Perl script on each of the clients. This script goes thorugh each of the Gluster mount points comparing the timestamps in the CHECK_FILE to the current system time alarming if the timestamp is off by more than a minute. Another test which hasn't been implimented was checking the contents of the CHECK_FILE with the data that is on the raw disk. Bash code to write timestamps and executed via cron once a minute. (write_timestamps.sh) http://glusterfs.pastebin.com/m5a220a6 Perl code to compare the timestamps which is executed on the client.
