We are configure some AIX servers and looks from SNMPwalk, we can capture RAM and SWAP usage etc.
The status information shown is "alarm at 15" but the performance data shown is different. Can this be adjusted?

Here's what the output looks like when you click on the overview.

Perhaps I should be using something else? This was taken from what a Linux check would've looked like.

20MB is not a big difference. This could be caused by the rounding or maybe, the value could have changed by the time you performed the second check (from the CLI). I am not able to recreate the issue in-house as I don't have an AIX test box. I ran the same plugin against a CentOS box and it seemed to work as expected - the values from the "Advanced" tab and the CLI matched.

Can you test the plugin against a Linux box to see if you will experience the same issue?

What is the version of the plugin that you are currently using?

Code: Select all

/usr/local/nagios/libexec/check_snmp_storage_wizard.pl --version

The difference is due to me running the screen grab at different times. I am not worried about that. I am just looking at the "alarm at 15" status information vs. what is shown in the advanced tab.

For Linux Machines we are using "Check_xi_service_snmp_linux_storage" for RAM.
which is using the same underline command and that is ok.

Code: Select all

# /usr/local/nagios/libexec/check_snmp_storage_wizard.pl -H smisdhadma01 -C nagios --v2c -m 'Memory' -w 80 -c 90
Memory buffers: 1%used(429MB/64428MB) (<80%) : OK

Code: Select all

# /usr/local/nagios/libexec/check_snmp_storage_wizard.pl --version
check_snmp_storage version : 1.3.3

Went back and looked at the command further and turns out it was the -v1 switch....

Code: Select all

# /usr/local/nagios/libexec/check_snmp_storage_wizard.pl -H edmnim02 -C nagios -m 'RAM' -w 80 -c 90
System RAM: 98%used(4284MB/4352MB) (>90%) : CRITICAL

Are you saying that it's now working properly for you?

Posted: **Mon Jun 15, 2015 3:10 pm**

Yes, I've removed the -v1 from the check command and it is working right for me now. Thank you.

Great, glad to hear that! I'll be marking this as resolved and locking the topic.
