Hello:
We run nagios 3.0.6 with ndoutils and nagvis for host visualization. We had
some problems with our nagios server a couple of weeks ago and we believe it
is related to mysql performance, we could see that the mysql process was
consumming from 80 to 90 % of the CPU in the monitoring server at certain
times. We could solve the problem by applying a couple of indexes to the
nagios database (the one used by ndoutils) as recommended in thread:
http://www.mail-archive.com/nagios-users@lists.sourceforge.net/msg23943.html
Afterwords we enabled monitoring for the nagios database by using the
check_mysql_health plugin and we see that the index usage for the nagios
database is under 10%. I am not a Database Administrator but I believe this
is a very low index usage.
I would like to konw if anyone has any recommendations about database
indexes applicable to the nagios database for ndoutils/nagvis.
Any tips/hints are appreciated
//Marco
