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.
