swap usage

[srikanth.kallu]

Hi,

I am trying to set alerts for swap usage.

I want alrets if 10 % is utilisaed as warning and 20% utilised as critical.

Now how do i set this ?

1. check_nrpe!check_swap!-a '-w 10 -c 20'

or

2. check_nrpe!check_swap!-a '-w 90 -c 80'

Thanks in advance.

i set the alert like this check_nrpe!check_swap!-a '-w 90% -c 80%' (First attachment)

But it still says Ok ( Second attachment )

Hi,

I think there is a bug in checking swap usage.

I have checked this on two of my servers AIX and LINUX

check_nrpe!check_swap!-a '-w 2 -c 1'

or check_nrpe!check_swap!-a '-w 100 -c 99'

but says status os Ok even if it is

SWAP OK - 81% free (820 MB out of 1023 MB)

We are looking into this issue as we speak. We will do some testing and get back to you as soon as we determine what is causing it.

This is not a bug, without adding % after each value, it is actually looking at bytes free not percentage. Please change your command to

Code: Select all

check_nrpe!check_swap!-a '-w 90% -c 80%'

Try it out and let us know. Sorry for the confusion, scottwilkerson had it all correct in the first post.

check_nrpe!check_swap!-a '-w 90% -c 80%'
