I don't beleive NSClient++ has a way of converting values, you would have to write a wrapper script to do that.

Have you reviewed this article?

Hi hsmith,

I have checked it that why i have set MB in my command. but still output was coming in bytes. Can you guide?

What happens if you try this from the command line? It's not going to give you oracle information, but I want to see if it gives the right unit

./check_nrpe -H 172.26.2.13 -c CheckCounter -a "Counter:Memory Available=\\Memory\\Available MBytes" ShowAll MinWarn=500 MinCrit=256

Please find the Out of what you have requested :

[root@VM-NAGIOSXI-TEST libexec]# ./check_nrpe -H 172.26.2.13 -c CheckCounter -a "Counter:Memory Available=\\Memory\\Available MBytes" ShowAll MinWarn=500 MinCrit=256
OK: Memory Available: 4048|'Memory Available'=4048;500;256
[root@VM-NAGIOSXI-TEST libexec]#

It seems like that the check produces the expected output (in MB).
Is this what you were trying to accomplish?

Hi Lmiltchev,

I want to monitor Memory usage (IN MB) of any process using checkcounter with thresholds. But i am getting the output in Bytes. :

[root@VM-NAGIOSXI-TEST libexec]# ./check_nrpe -H 172.26.2.13 -c CheckCounter -a "Counter:oracle_Memory_Usage_inBytes=\\Process(oracle)\\Working Set" ShowAll
OK: oracle_Memory_Usage_inBytes: 1.42291e+009|'oracle_Memory_Usage_inBytes'=1422909440

Also i wanted to set threshold value for CPU usage of any process :

./check_nrpe -H 172.26.2.13 -c CheckCounter -a "Counter:oracel_CPU_Usage_in%=\\Process(oracle)\\% Processor Time" ShowAll
OK: oracel_CPU_Usage_in%: 0|'oracel_CPU_Usage_in%'=0

When you look at the actual counter in Windows, how is it displayed? Can you show us a screenshot?

This second one looks like you spelt oracle wrong -

Hi rkennedy,

checkcounter for CPU is giving correct output, i just want to set value for critical and warning. Main issue is with Process memory usage, i want output in MB,currently its giving out in Bytes.

Got it.

Can you navigate to the Performance Monitor on windows, and when you look at the actual counter, what type is it displayed as? Can you show us a screenshot?

Hi rkennedy,

Today when i was checking the cpu usage of a process, i am getting wrong information :

[root@VM-NAGIOSXI-TEST libexec]# ./check_nrpe -H 172.26.2.137 -c CheckCounter -a "Counter:oracel_CPU_Usage_in%=\Process(oracle)\% Processor Time" ShowAll MaxWarn=80 MaxCrit=90
CRITICAL: oracel_CPU_Usage_in% = 99|'oracel_CPU_Usage_in%none'=99;80;90

but when i am checking for the cpu usage of oracle, its just 25 % usage. but result which i am getting is completely different.

please help to get the correct values?
