[Xymon] RRD files are too big

[Mills,David (HHSC Contractor)]

Thx, Shawn...

I agree that the naming suggests some unique connection info like an IP, but I don’t see any of our IPs embedded into those names. The snippet I offered earlier was from a Windows box. The following is an example from one of our Solaris 11 hosts. Note that the RRD files with "net<digit>" correspond to iface names  net0, ... In the example that follows, the "vnetldc" probably refers to a virtual network interface tag since this host is part of a Solaris LDOM. The trailing hex digits probably have the same identifying function as the four dotted numbers in my original example, though I still don't know what they mean:

Looks like the filenames are generated from information sent by the xymon client running on the host.  I see files with interface names on my Xymon server. These are from a client running on a SPARC Solaris system:

rrd/sahara/ifstat.bge1.rrd
rrd/sahara/ifstat.bge3.rrd
rrd/sahara/ifstat.bge2.rrd
rrd/sahara/ifstat.bge0.rrd

I'm running 4.3.23, RPM package built from source.  These ifstat files are 38K in size.

I would have guessed that the numbers were IP addresses, but you've got two of them in that list starting with zero, and one ending with zero, so if those are IP addresses, there may be an invalid address configured somewhere.  And if they're not IP addresses, then I have no idea what they are, and you may need to look into the client running on the host.

Thanks,
Shawn
