Trying to setup memory usage monitoring for Nagios using the
check_snmp_mem.pl from Nagios SNMP plugin.
I could not even get it working from the command line, I mean I go to
/usr/lib/nagios/plugins and run the script, it gets a "No response from remote host" error.
[root@nagios plugins]# ./check_snmp_mem.pl -H rhel01 -C public -N -w 90,20 -c 99,30 Argument "v6.0.1" isn't numeric in numeric lt (<) at ./check_snmp_mem.pl line 319. ERROR: Description table : No response from remote host "rhel01".
Any SNMP configurations required on the monitored server?
