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,
