MRTG graph for CPU utilization on GTM and LTM

We were using MRTG to monitor the cpu utilization on out older BigIP boxes and have now converted to GTM. Obviously the mrtg graph is now broken and I am going to have to rebuild it.

 

Does anyone know how to generate the graph. It seems as though I have to add a bunch of different oids in order for this to work. This is no small feat since I am a novice at mrtg.

    Have you looked into Cacti? It uses MRTG but has a much better interface and there are a quite a few pre-defined scripts already. Here is a link to the F5 BigIP v9 host template.

    I used it at a large Telco to gather individual port stats on over 200 switches plus several thousand routers.

    I heard good things about cacti, but right now we do not plan on switching to cacti.

     

    I need to get this working quickly.

     

    If someone has created these graphs using mrtg please let me know.

    MRTG is a thing of the past, most users will have Cacti, I strongly recommend you convert.

    2nd that... if you have a spare PC or even a vmware session you can create somewhere, you can load up a copy of cactiEZ in about 10 minutes... That'll give you a full ocpy of Cacti,plus plugins like mactrack, weathermap, discover and also ntop.

    The quick and dirty guide that I use for MRTG is in "Open Source Network Administration" by James Kretchmar

     

     

    It walks you through using cfgmaker (which ships with mrtg) to poll a device and create a config for it.

     

     

    I've not used it for BigIPs, so I can't speak to what sort of mods are required to add F5 mibs, but it does work reasonably well and quickly.

    I made some modifications to the cacti template from the forums to include some of the GTM information, some of the oids you are looking for are included, so you can pull them out of the XML files.
