Morning all,

>> and I've worked with Nagios for ages and love it above all
>> others,

Like Alan, I used Nagios (version 2) in a past life. It was small and efficient and because we run databases on a cluster, could follow a database around the servers on the cluster - it logs in using tnsnames.ora/Oracle Names aliases. The web interface means almost anyone (with the correct privs) can access the stats and reports. Very nice.

I think it has progressed to V3 now and that there is a fork named Icinga (http://www.icinga.org/) which is reportedly much better in the performance stakes. I haven't tried it (yet!)

Been there, suffered that! Open View from HP is the "monitor of choice". It doesn't use database aliases and when a database fails over onto another cluster node, OV can't follow it unless it was *manually* failed over. I think this is a pretty intrusive monitoring tool - plus it needs a whole slew of privileges and sets up the monitoring user in the database with a password that it remarkably (a) hard coded and (b) the same as the username. Yuk!

Cheers,
Norman.
