A while back I wrote an article on Graphing the LTM with Cacti.  The article was mostly pointed towards installation and configuring a graph from a pre-configured host template.  In this video, I'll show you how to create a graph template to track the WebAccelerator Hit Counts to memory and disk.

A couple of notes before you get started.

  1. To query the WebAccelerator mibs by name, you'll need to create a symlink (see solution 8484).  Once the symlink is in place, you can use snmptranslate -On <object Name> to get the oid string you need to build your data templates.  For our graph template, we need to get the oid string for WA::imcHitCount and WA::hdsHitCount
     [root@golgotha:Active] config # snmptranslate -On WA::imcHitCount . [root@golgotha:Active]
     config # snmpget -v 2c -c public localhost:12406 . WA::imcHitCount.0 = Gauge32: 0 [root@golgotha:Active] config # snmptranslate -On WA::hdsHitCount . [root@golgotha:Active] config # snmpget -v 2c -c public
     localhost:12406 . WA::hdsHitCount.0 = Gauge32: 0
    Now we know the strings, and that the WebAccelerator is responding locally.
  2. The WebAccelerator queries must be directed at port 12406 instead of the standard port (161)
