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
