snmp_check not working with text OID after CPAN installation
Posted: Tue Feb 22, 2022 6:26 am
Hi, yesterday I was adding some firewalls on my Nagios.
I added successfully a SonicWall SMA virtual appliance using several SNMP checks, and that was working fine until yesterday at around 10:45.
Note that I copied related MIBs to /usr/share/snmp/mib folder.
My linux history shows that at that time I executed the command CPAN. I had to use CPAN to install Nagios::Plugin but it failed, then I tried Monitoring::Plugin and it failed as well. Lastly, I did yum install perl-Nagios-Plugin (removed today to try to solve my problem).
This was needed to check a Cisco ASR router.
Today I checked Nagios and turns out that all the checks returns
CRITICAL - Plugin timed out while executing system call
My snmp_check command:
and this is one of the checks for that SMA appliance
if I manually execute the command, this shows:
but when I use the numeric OID instead, it works fine
check_snmp v2.3.3 (nagios-plugins 2.3.3)
