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

Let us know if you have problem with the script.

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 ;
