[mrtg] Re: Alternatives to ifDescr

[Kruepke]

Vijay,

You may or may not have have considered this already, so if you have, forgive me...

My preference when doing MRTG config files is to use cfgmaker to get the initial information about the router (or other device) and to make sure that SNMP is working to that device.  Then I manually edit the output of cfgmaker to make it more useful to me.  The PageTop option in the config file allows you to specify exactly the text that should appear at the top of the page (in HTML).  Then you can do anything you want.  In addition, I like to use options like Directory that do not normally appear in cfgmaker output.

Obviously this does not help if you have a LOT of devices or if your problem is not being able to differentiate between the ports/interfaces in the cfgmaker output.  If you are at all Perl-savvy, you can search cfgmaker for the part when it outputs "PageTop" and work from there.

Good luck,
Keith

Subject: [mrtg] Alternatives to ifDescr



Hello,

I'm a new user of MRTG and need some help.

I'm using MRTG to monitor link utilization on a Redstone router but the
output obtained does not indicate the interface slot/port number, only
"Redstone Fast Ethernet" and so on. Upon checking the MIB definitions, it
appears that ifDescr will only output this and I need to use ifName and/or
ifAlias to obtain the slot/port number and the alphanumeric description
associated with that IP interface.

What modifications do I need to do on the cfgmaker and/or mrtg script(s) in
order to obtain the desired output?

Thanks in advance.

- Vijay
