check_snmp_mem.pl plugin giving wrong results about manubulon-snmp

[dnsmichi]

Hi,

first off, fill in the issue template and show the exact results from the plugin call. Second, I don't use Nagios, if that's a specific requirement.

If you need help on specific SNMP monitoring tasks, either consult GitHub Enterprise support or pick the right community for your tool (Nagios, Icinga, etc.).

That being said, I don't consider this being a bug.

Cheers,
Michael

@DNS already updated the request with requested information. Here the problem is the check_snmp_mem.pl is not showing exact result while looking for the total consumed memory. its showing wrong result

for more details.

The below is the memory consumption information got by "free -h " command

              total        used        free      shared  buff/cache   available
Mem:   16051       11135        1037           5        3879        4581

checked both the ways:

1. with -m

/check_snmp_mem.pl -H xxxxx --login=xxxxxx --passwd=xxxxx --privpass=xxxxx --protocols=sha,aes -m -w 90,90 -c 95,95 -f

Ram : 93%, Swap : 0% : > 90, 90 ; WARNING | ram_used=15360688;14793458;15615317;0;16437176 swap_used=0;0;0;0;0

I think, here its calculating as

(used+ cache)
__________________ * 100
Total

2. without -m

/check_snmp_mem.pl -H xxxxx --login=xxxxx --passwd=xxxxx --privpass=xxxxx --protocols=sha,aes -w 90,90 -c 95,95 -f

Ram : 75%, Swap : 0% : ; OK | ram_used=12260732;14793458;15615317;0;16437176 swap_used=0;0;0;0;0

Here its calculation is
(used)
________ * 100
Total

But actually we need :

[ (used)-(cache)]
___________________ * 100
Total

any suggestion here ?

You can look into the code and analyse its behaviour. I'm not actively maintaining these plugins anymore, but the Perl code should be fairly readable for adjustments and tests.

Hello @vivuu1989 and @dnsmichi . I'm new member here but I recently had the same problem and I solved it changing the check-snmp_mem.pl script. It works with just one output (-m flag is disable right now)

This is the code (you must to change the extension from txt to pl):

check_snmp_mem.txt

I hope it solv your problem.
