If running the latest version(s) of Nagios and the plugins, using mysql,
and gathering trending info, is there a list available of the best
performance tweaks one can make? I seem to read a lot that mySQL is a
resource whore when also on the Nagios server. Some have commented on
seeing significant increases when moving it elsewhere. Others have
mentioned adding lines like "innodb_flush_log_at_trx_commit = 2" into
the mysql config file, while others have also mentioned database
indexes, etc. Of course, for non-DBA's, knowing which databases to
create indexes on (or how to do it without mucking it up) are up for
debate. Log file rotation is always a good one, but this seems to be
built into Nagios 3.x, though I've read of people running Cacti on their
Nagios server as well and Cacti has no default log rotation. So...
perhaps everyone could include the steps they took to resolve various
performance issues... perhaps also including the actual steps taken (ie:
if making indexes, which ones and why) and we can cull them into the
Nagios wiki on NagiosExchange?
