Monitoring BigIP TMM-Utilization with Nagios and snmp

Hi!

 

 

I found some cacti-scripts at the cacti site to read the tmm-utilization from our bigip-boxes.

 

I turned it into a nagios-plugin for monitoring.

 

 

Here's a blogpost about it, if anyone is interested in such a thing. It supports nagios performancedata for graphing.

    I'm not sure whether it's the same but you can give this link a try: http://www.sladder.org/?p=317

    Hi

     

     

    first of all thanks so much for this plugin, great work!

     

     

    I would like share with you something I have spotted as I have been using this plugin and always getting the same log output

     

     

    "TMM ulitization= 1 "

     

     

    Having a look the script the function to round the variable I think it is not correct

     

     

    Round to integer $tmm_cpu = int($tmm_cpu + .5);

     

     

    This is truncating the decimals with the int casting as you are only adding 0.5 and the number is in a range between 0 and 1, so I have changed it and now it is displaying fine:

     

     

    Round to integer $tmm_cpu = int($tmm_cpu * 100);

     

     

    just multiplying by 100 you get the percentage

     

     

    >xxxx:/usr/local/nagios/libexec ./check_f5_tmm.pl HOST STRING 76 90

    >OK: TMM utilization is 51 | pct=51

     

     

    hope it helps, thanks

    Hi @hiperesfera,

     

    I know its quite an old thread, but really need some help on this. I tried to use above plugin and getting below error

     

    root@76f14f428392:/usr/local/nagios/libexec ./check_tmm_utilization HOST_IP 76 90

     

    Illegal division by zero at ./check_tmm_utilization line 49.

     

    Below is line 49

     

    my $tmm_cpu = (( ($polled_oids_1->{$tmmTotalCyl} - $polled_oids_0->{$tmmTotalCyl}) - ( ($polled_oids_1->{$tmmIdleCyl} - $polled_oids_0->{$tmmIdleCyl}) + ($polled_oids_1->{$tmmSleepCyl} - $polled_oids_0->{$tmmSleepCyl}) )) / ($polled_oid s_1->{$tmmTotalCyl} - $polled_oids_0->{$tmmTotalCyl}) ) * 100 ;
