How to modify catos_interface.php to be able to get IfAlias?

Post by MI1 »

Hi all,

this question was asked inside topic [http://forums.cacti.net/viewtopic.php?f ... s&start=15] about CatOS templates but so far I cant find solution.

We have Cacti 0.8.7g with many templates developed or downloaded from forums. For IOS Cacti is using this part for gathering IfAlias:

Found data query XML file at '/var/www/cacti/resource/snmp_queries/interface.xml'

Code: Select all

<ifAlias>
                        <name>Alias (IF-MIB)</name>
                        <method>walk</method>
                        <source>value</source>
                        <direction>input</direction>
                        <oid>.1.3.6.1.2.1.31.1.1.1.18</oid>
                </ifAlias>
which is fine only for IOS, not for CatOS. For graphing CatOS we use this script:

Code: Select all

cat /var/www/cacti/scripts/cisco_catos_interface.php
<?php

/* do NOT run this script through a web browser */
if (!isset($_SERVER["argv"][0]) || isset($_SERVER['REQUEST_METHOD'])  || isset($_SERVER['REMOTE_ADDR'])) {
   die("<br><strong>This script is only meant to run at the command line.</strong>");
}

I believe this script was develoved by community. The problem is that CatOS script do not have capability to query devices for IfAlias [1.3.6.1.4.1.9.5.1.4.1.1.4] so there is need to add it there.

I started with adding OID to array but that is not enought so if anyone can get me a hand how to impement logic to this? Hints, examples or something I can start with?

Well, it seems that I overlooked that OID is already there but as a portName, anyway Cacti is not albe to show Alias (IF-MIB) as I can see them using snmpwalk. This script is somehow broken...
