[mrtg] ifOperStatus and if-template problem

[Jakub M]

Hello,

I have a small problem with generating proper cfg file. I want to
monitor a link status for my devices. I have made a template for
cfgmaker, but when I run mrtg with a generated cfg, I don't get any
results (no values on charts)

I run cfgmaker like this:

cfgmaker --show-op-down --global "WorkDir:
/home/user/Scripts/bunch/out/" --global "Options[_]: growright, gauge"
--if-template=link.template public at 192.168.xxx.xxx > mrtg.cfg



When I do normal snmpwalk, I get

IF-MIB::ifOperStatus.1 = INTEGER: up(1)
IF-MIB::ifOperStatus.2 = INTEGER: up(1)
IF-MIB::ifOperStatus.3 = INTEGER: down(2)
IF-MIB::ifOperStatus.4 = INTEGER: up(1)
...

My template file looks like this:
