check_centreon_snmp_memory never exclude swap #705

Closed imnotme closed 7 years ago

imnotme commented 7 years ago

Hi, The "-S" option from the "check_centreon_snmp_memory" plugin seems to not working :

[root@monitoring plugins]# ./check_centreon_snmp_memory -H 192.168.0.1 -C public -S Total memory used : 13% ram used : 98%, swap used 0% | used=137334784o size=1051549696o [root@monitoring plugins]# ./check_centreon_snmp_memory -H 192.168.0.1 -C public -S -w 80 -c 90 Total memory used : 13% ram used : 98%, swap used 0% | used=137453568o size=1051549696o [root@monitoring plugins]# ./check_centreon_snmp_memory -H 192.168.0.1 -C public -w 80 -c 90 Total memory used : 13% ram used : 98%, swap used 0% | used=137445376o size=1051549696o [root@monitoring plugins]# ./check_centreon_snmp_memory -H 192.168.0.1 -C public -w 10 -c 90 Threshold (10%) excedeed : total memory used : 13%, ram used : 98%, swap used 0% | used=137449472o size=1051549696o

Plugins version : [root@monitoring plugins]# ./check_centreon_snmp_memory --version Undefined subroutine &main::print_revision called at ./check_centreon_snmp_memory line 99.

Note I have to use this one since the default linux plugin for memory is not working either, I think it's a server issue for this one since the request for .1.3.6.1.4.1.2021.4.13.0 is returning "[noSuchObject]". Does it exit a switch in this plugin to not requesting this OID ?

Could you test with following command:

/usr/lib/centreon/plugins/centreon_linux_snmp.pl --plugin=os::linux::snmp::plugin --mode=memory --no-swap --hostname=192.168.0.1 --snmp-version='2c' --snmp-community='public' --subsetleef=1

Which version of net-snmp and linux do you use ? It shouldn't timeout if the OID is not present.

imnotme commented 7 years ago

Target is Debian 6 (yeah i already know) and net-snmp 5.4.3

(oopsie fat fingered the close button)

garnier-quentin commented 7 years ago

I'll try to install that version. But it seems like a net-snmp bug.

imnotme commented 7 years ago

fwiw, monitoring server use version 5.5 of net-snmp (CES iso, up to date)

garnier-quentin commented 7 years ago

It's not a problem about the client i think.

imnotme commented 7 years ago

Ok. Thanks for quick answers by the way :)

Have you checked the "-S" option from the "check_centreon_snmp_memory" plugin, or is this one deprecated?

garnier-quentin commented 7 years ago

This one is completely deprecated.

garnier-quentin commented 7 years ago

Do you use docker ? https://github.com/centreon/centreon-plugins/issues/708

But someone had the same kind of problem.

imnotme commented 7 years ago

No, no docker used.

On the target server :

snmpget -v2c -c public 127.0.0.1 .1.3.6.1.4.1.2021.4.13.0 iso.3.6.1.4.1.2021.4.13.0 = No Such Object available on this agent at this OID

Found this : https://sourceforge.net/p/net-snmp/bugs/2250/

Edit before posting : i followed the get-response packet, and... blocked by some firewall between probe and probed. Once firewall issue resolved, it worked using the "centreon_linux_snmp.pl" plugins. For instance, check_centreon_snmp_memory still don't care about the "-S" option ;)

garnier-quentin commented 7 years ago

Ok. So the problem is solved. Great!
