We've got two xymon servers running 4.3.0-0.20090209. The clients are mostly hobbit 4.2.0. The goal was for the servers to run in parallel and stay in sync. I don't know if I did something wrong, but we're having a problem with the trend graphs and rrd. The rrd-status.log is full of messages like:
2009-05-19 12:26:02 RRD error updating /var/opt/hobbit/rrd/myhost.mydomain/la.rrd from 10.15.50.111: illegal attempt to update using time 1242750061 when last update time is 1242750061 (minimum one second step)
Each client has BBDISP="0.0.0.0" BBDISPLAYS="10.15.50.10 10.15.50.12" in it's config so that it's sending data to both servers.
Both servers have the same in their hobbitserver.cfg file.
Doing this made sense to me so that if one server went down, it would still be getting client data. Also, we can disable/enable things on one server and the other show the appropriate status. Only one server is running bbpage, however.
Did I configure things incorrectly for multiple servers or is there a deeper problem?
Thanks, Ken

Hi,
we had a similar setup, but dropped it in favor of a single server, basically because it was too hard to keep the list of disabled (blue) services in sync. (The server is an ESX VM so unlikely to die anyway.)

Your problem is that you have two hobbitd_client processes running. Both servers receive "client" reports and will decompile them into separate disk/vm/... tests. The results are then also sent to the other server.
You could try either to disable the hobbitd_client module on one server, or remove the other server in each server's BBDISPLAYS setting. Both approaches have their drawbacks, though.
