How dows one go about handlingSNMP OID of interfaces changes

[alform2000]

Greetings.
It is a sad fact of life that SNMP OIDs of network interface for a wide variety of interface can and DO change across reboots, OS/Firmware upgrades etc.
In MRTG one could specify interfaces by IP, but i appears that cacti cannot. Ouch. Manual tracking of the changes *NOT* being an option (I monitor hundresds of devices) , how to cope with this? I'd be willing to run a cron script on a few minute basis and upgrade the graphs definition, but cacti internal are a deep mistery to me.....

Advanced Thanks,

I really haven't every looked at it, but isn't the autom8 plugin what you are looking for?

We usually keep those interfaces by using ifDescr as the "real" index. This is done by

Code: Select all

<index_order>ifDescr:ifName:ifHwAddr:ifIndex</index_order>

in the XML.
Not verified, but when moving the ifIP in front of that, you _may_ receive what you want. Don't flame me, if I'm wrong
