Sorry for the replying to an old message, but seems there hasn't been any recent discussion of snmp polling.
I believe I have everything working perfectly with 4.3.18, I see clientdata coming in on my test switch and I am collecting data on the [ifmib] definition in "server/etc/snmpmibs.cfg". What I don't have is trending on that data. I am assuming that is because the data is coming in under to xymon via "client" message versus a "data" message.
To get trends, I assume I could write a xymond_channel worker listening on the client channel and using a filter option to target only "snmpcollect" messages. This would process the raw data, and submit the data I want to trend on via "data" messages ?
Or am I just to bogged in the details and missing something obvious ? Thanks, -Steve

I would like to have an examle of the snmp configuration file: hobbit-snmphosts.cfg--
Here's one:
[osiris.hswn.dk] version=2c community=public ip=172.16.10.100 ifmib={172.16.10.100}
ifmib={*}
hrsystem
hrstorage=(Real Memory)
hrstorage=(Swap Space)
hrstorage=(/)
hrstorage=(/work)
hrtask=<*>To understand how it works, you need to look at the hobbit-snmpmibs.cfg file also. In this file you'll find an [ifmib] section that begins with
[ifmib] keyidx (IF-MIB::ifDescr) keyidx [IF-MIB::ifPhysAddress] keyidx <IF-MIB::ifName> validx {IP-MIB::ipAdEntIfIndex} ifDescr = IF-MIB::ifDescr
Note the different kind of parentheses / brackets ? What these do is they act like an index into the list of network interfaces. So the line "ifmib={172.16.10.100}" means "grab the ifmib data for the network interface whose {IP-MIB::ipAdEntIfIndex} (IP-address) is 172.16.10.100.
If you wanted the statistics from the "eth0" net-interface, you would use "ifmib=(eth0)".
The line that just read "hrsystem" has no index, because this data
- part of the Host Ressources MIB - only has one entry globally (e.g. there is only one count of how many users are logged on).
The "hrtask=<*>" of course means to fetch information about all of the tasks running on the system.
