Nagios Support Forum

Hello team,

Am in the process of creating new nagios server as my old nagis server was have performance issue with writing rrd data and log .

now i got 6 hard drives . Suggest me how i can do the raid and partition for nagios , whether i can create a separate partition for performance date write ?.

The underlying disk/partitioning doesn't matter really to Nagios, but in general RAID 0 is going to be quickest. Raid 0 is quick but doesn't offer fault tolerance. You'll want to look into the various types of RAID to find the one that offers you the balance of speed and tolerance you find acceptable. Regarding partitioning I'll point out that most of logs are stored in /usr/local/nagios/var, /usr/local/nagios/share/perfdata stores the RRDs files, and /var/log will have the messages and web server access logs and these could be their own partitions. Note that these locations are defaults in most cases and you may need to adjust for your install.
