Nagios and random snmp errors Description/Type table

[madhuneal]

Team Greetings,

I'm running Nagios instance on top AWS VPC network, I've open all ports and within ACL and I'm able to see the traffic, but I'm not able to catch the issue and we are firefighting.

This issue is happening daily once random timings.

Please find the configuration details below:

### Process - Storage

define command {
command_name check_snmp_storage
command_line $USER1$/check_snmp_storage.pl -H $HOSTADDRESS$ -C HelloIMin-2 $USER8$ -m $ARG1$ -w $ARG2$ -c $ARG3$ $ARG4$ $ARG5$
}

define service{
use generic-service,graphed-service
host_name STDB02
service_description BACKUP12
check_command check_snmp_storage!"^/backup"!85!90!
}

Are these long distance snmp queries? Sometimes it's best to wrap SNMP into a check_by_ssh or check_nrpe if you're experiencing timeouts and the data is traversing long distances.

If that's not the case - is it true that the check completes successfully sometimes, just not all the time? I'm not totally clear on that.
