snmp traps

[hanya.radwan]

most snmp traps services aren't working as before(before upgrade to 2014 R1.0)
one snmp service at nagios 2014 R1.0 returns the following error:
External command error: Bad SIZE syntax (OCTETSTRING): At line 203 in /usr/share/snmp/mibs/HPOV-NNM.txt
Bad parse of OBJECT-TYPE: At line 203 in /usr/share/snmp/mibs/HPOV-NNM.txt

Timeout: No Response from 10.202.6.23:161.

and from test command, it gives the following error:
COMMAND: /usr/local/nagios/libexec/check_snmp -H 10.202.6.23 -P 2c -C public -o numberOfSessions.6 -u sessions --rate --rate-multiplier 300 -w 5: -c 1:
OUTPUT: Cannot create temporary filename

and from server returns the following:
[root@nms ~]# /usr/local/nagios/libexec/check_snmp -H 10.202.6.23 -P 2c -C public -o numberOfSessions.6 -u sessions --rate --rate-multiplier 300 -w 5: -c 1:

Looks like what I suspected, check_snmp does not have permissions to write to the directory where it will keep it's temp check files. Can you try running that command as root? Did you change the directory where that plugin places those files?:

It appears to happen specifically with --rate.

Code: Select all

/usr/local/nagios/libexec/check_snmp -H 10.202.6.23 -P 2c -C public -o numberOfSessions.6 -u sessions --rate --rate-multiplier 300 -w 5: -c 1

[hanya.radwan]

the command gives the following:
[root@nms ~]# /usr/local/nagios/libexec/check_snmp -H 10.202.6.23 -P 2c -C public -o numberOfSessions.6 -u sessions --rate --rate-multiplier 300 -w 5: -c 1

also check_snmp has the following permission

[root@nms ~]# ll -d /usr/local/nagios/var/check_snmp
drwx------ 2 nagios nagios 4096 Jun 9 20:48 /usr/local/nagios/var/check_snmp

[sreinhardt]

The with those permissions, the apache user, which is part of the nagios group would never be able to create or modify files in that directory. Try the following:

Code: Select all

rm -rf /usr/local/nagios/var/check_snmp/*
chmod ug+rw -R /usr/local/nagios/var/check_snmp/

Now both apache(test command button) and nagios core can add\modify\remove files in that directory.

[hanya.radwan]

i did the command and the permissions becomes as the following:

[root@nms ~]# ll -d /usr/local/nagios/var/check_snmp
drwxrw---- 2 nagios nagios 4096 Jun 9 21:12 /usr/local/nagios/var/check_snmp

[sreinhardt]

That looks much better. Are you able to successfully run the command from nagios core now? Preferably by letting it be scheduled or by running an immediate check and not via the test command button?

the same error:

Again, please do not use the test command button, this is run via the apache user and will often have issues overwriting files created by the nagios and root users, as it is now.

As for these, the response should be identical between cli and running from the XI interface. Just to confirm, these are from the same system? I also note that your first command returns proper results, however the second times out due to the system not responding, this is very indicitive of either differing systems when running the command or network issues. Please try the following command.

Code: Select all

cd /usr/local/nagios/libexec
su - nagios ./check_snmp -H 10.202.6.23 -P 2c -C public -o numberOfSessions.6 -u sessions --rate --rate-multiplier 300 -w 5: -c 1:
