Disk Idle Time

[JohnFLi]

After many times of banging my head into the table, I finally figured out how to get check_nt to get perfmon data from Windows.

Code: Select all

./check_nt -H 10.100.5.38 -p 12489 -v COUNTER -l "\\LogicalDisk(C:)\\% Idle Time","%.2f"

and if the server isn't really doing much, the disk will be idle 90+ % of the time. As a result, setting a warning to 80% and criticle to 90% really isn't going to work.

basicly, I need to know when idle time gets below 20%

any ideas?

hmmm, I may have figured it out. Tell me if this looks valid

Code: Select all

check_command                  	web_disk_idle!COUNTER!-l "\\LogicalDisk(C:)\\% Idle Time","%.2f"!-w >20!-c >10

what I think I told it to do was WARN me if idle time gets below 20% and criticle at less than 10%

Change:

Code: Select all

-w >20!-c >10

To:

Code: Select all

-w 20!-c 10

The problem with that, is that if the drive isn't doing much, it's idle time will be close to 100%
What I need to know is when Disk idle time is below 20%.

I have not seen or used < or > with warning and threshold limits, normally it is done with : and ~, such as https://nagios-plugins.org/doc/guidelin ... HOLDFORMAT I'd suggest changing the < to : and trying it out. That should give you a less than 20% usage sends an critical notification, type of scenario.

Box293,
After going over with what you said....
I noticed you had the crit level below the warning.

I did a test with the settings at -w 99!-c 90

I got warnings at 92.21, 97.46 and 92.12
I got a critical at 88.26 and 77.08
and an OK at 99.77


I guess this thread can be closed.
