Cacti is ignoring hash marks in interface aliases
- by Matt Simmons
I'm attempting to set up Cacti to monitor a router's interfaces, and I'm having trouble getting the graph templates to show the information that I'd like.
Our interface configuration looks like this:
interface GigabitEthernet3/6
description WalljackNumber # Server info
no ip address
no shutdown
switchport
switchport access vlan 116
switchport mode access
ip dhcp snooping trust
spanning-tree portfast
The "Server Info" string is really just the machine name, and a short relevant description, such as "PolarSprings vmnic2". The important part appears to be that it follows the hashmark.
When I run snmpwalk, I get the proper output:
IF-MIB::ifAlias.230 = STRING: WalljackNumber # Server info
But in Cacti, when I go into the graph templates and set the title to this:
|host_description| - Traffic - |query_ifName| (|query_ifAlias|)
All that shows up in the graph is:
switchname - Traffic - Gi3/6 (WalljackNumber #)
Which strikes me as a little weird. What I suppose MAY be happening is that somewhere in the cacti stream, it's interpreting # as being a comment and stripping everything after, but I'm not sure.
I was hoping someone could tell me that this was a known documented behavior, or that I could change it in a setting that I wasn't aware of. The alternative answer is to change the delimiter from # to something else, but I've got over a thousand lit switchports on an old college infrastructure, and I'm not sure what else might be relying on them.
