Yes. Although larousse is getting old, and the install running on it is too. We might want to do a reinstall before that.
Fedora Core 2 actually, should I ask Solar to upgrade it to FC3 so ? :o)
Reusing gmetad data is probably a better idea, the data in nagios and ganglia would be the same. One of the problems is that we will have to code a nagios plugin that cache the gmetad data to avoid multiples queries (we probably dont want to query gmetad for cpu, then for memory then for nfs call, then for each disk space usage).
I don't know ganglia too well, but this seems like the best option to investigate. If ganglia is flexible and uncomplicated enough to add new metrics easily, then this could certainly work.
Tim Starling added a metric for NFS server calls. So we can probably add some more stuff.
Can we use SNMP for devices that support it, and use ganglia for the rest?
In my experience, SNMP is nice and easy for things that the standard net-snmpd supports, but it gets nasty beyond that, i.e. if you want to add things yourself...
In my experience, adding new measures in snmp is easy. You have to add the script that return data, then it generates the oid accordingly. Debian got some nice examples in the snmd.conf .
Can we start installing snmpd on all servers to at least get some basic data ? :o)
cheers,
