ifAlias - traffic ** description ** at CISCO

RH 7.3 box []
cacti 0.8.3a

Hi,

sorry IMHO we had this a few times, but I'm a little confused.
I want to generate traffic graphs via SNMP.

by default I got following discription e.g.:
GW-name - Traffic - Se3/3

Ii would be fine to get something like
GW-name - Traffic - Se3/3 - *main ISP pipe - ID676766* - (192.168.1.1)

This means to include " ifAlias - ** description ** ".

I found something that I've to modify "include/snmp_functions.php" to got this.
Is this correct? What I've to do exactly, or is there an easier way.

Why is this not per default active (or included in main code) ?

Sorry for this question, but I'm new as a cacti user. Hope I understand correct

Hope somebody could help me

cheers
Chris

You can modify the default title format that Cacti uses on new traffic graphs by doing the following.

Select "Data Queries" on the Cacti menu, and click "SNMP - Interface Statistics". Depending on whether you are creating your graphs in bits or bytes, select "In/Out Bits" or "In/Out Bytes". Under "Graph Template - Interface - Traffic..." you will see the three titles that Cacti will evaluate (in order) to form the title for new traffic graphs. Feel free to delete these and add your own.

Going by your explaination, you would probably want something like:

Code: Select all

|host_description| - Traffic - |query_ifName| - *|query_ifAlias|* - (|query_ifIP|)

Thanks Ian,

works WELL !!

[Remark for everybody, I run in dozens of Problems under RH8&9 crappy Rel./ - 7.3 works fine => I look forward to Fedora 1.0 (RH9.1)]

Can we modify this php page(I mean polling host page) for adding anoter column to learning which interfaces up or down?
how?

I will end up doing this in some form or another. Instead of adding another column I will probably highlight any such row in red. This is going to have to be added through the XML file structure of data queries somehow and will have to be generic enough to work with other things. I would expect this in the 0.8.4/0.8.5 range of things.

Hi
I have added the code to the as per the instructions and it works well if I create a new interface check, however it has not updated the existing graphs, i.e. it still shows interface ' router_name - traffic ' on the gragh itself even though the Data Query [SNMP - Interface Statistics] shows that all interfaces have the updated appropriate Alias (IF-MIB)

Is there a way to accomplish this without having to remove the existing data sources and starting again?

You might want to uncheck "Use Per-Graph Value (Ignore this Value)" within the graph template , title section

Hi All,

I have noticed that |query_ifAlias| is trucated to 15 characters. Is there a way for the whole string to be used?

What was determined as the way to get the query_ifAlias to show on Graph title?? I've tried adding that to the query section for the interface template i'm using and moved it to the top?? still no go getting that to display?? Any suggestions that i'm missing? or not seeing?

Thanks

First, you must be sure that ifAlias is reported by your target. If not (verify using snmpwalk!), |query_ifAlias| will never be substituted by the correct value. In this case, cacti will use the next title substitution defined by the Data Query for that Graph Template.
This restriction holds for ALL |query_*| Variables. If use use |query_ifAlias| - |query_ifDescr| and ifDescr is empty => NOGO.
