[Xymon] RRD files are too big

[Mills,David (HHSC Contractor)]

Hey, Folks...

I posted on this issue a few months ago (cf http://lists.xymon.com/archive/2017-November/045048.html),  but still need help.

I migrated / upgraded from Xymon 4.3.3 on a Solaris 10 host to a Linux host (RHEL 6) using the Terbithia binaries (4.3.28), and things have been doing well for the most part. Unfortunately the new RRD files are massively bigger than the original ones on the old server, causing a lot of space issues on the file system.

The old RRD files took up around 38KB each (avg.) but the new ones are fairly uniform at 400+KB each.

Can anyone please tell me how to get those big files down-sized back to something much closer to the old sizes? Or, perhaps, someone can point me at the parameters Xymon uses that determine the RRD file sizes?

FWIW, this is a representative listing of one host's RRD files:
