Project at Nagios Exchange
Download plugin:
- Code: Select all
wget https://github.com/glensc/nagios-plugin-check_raid/releases/download/4.0.0/check_raid.pl -O check_raid
chmod +x check_raid
Sample plugin output:
- Code: Select all
# ./check_raid
OK: tw_cli:[c0(9650SE-4LPML): u0:OK, (disks: p0:OK p1:OK p2:OK p3:OK)]
Next step is to add custom EXEC section into SNMPd configuration on the server. It will allow us to retrieve plugin output remotely via SNMP protocol.
We can add it into default configuration file (/etc/snmp/snmpd.conf) or use additional configuration file (/etc/snmp/snmpd.local.conf) which is also parsed by default:
- Code: Select all
#EXEC
exec check_raid /scripts/check_raid
Restart SNMPD to apply configuration and query check_raid plugin remotely:
- Code: Select all
# snmpwalk -c public -v2c server.example.com 1.3.6.1.4.1.2021.8
UCD-SNMP-MIB::extIndex.1 = INTEGER: 1
UCD-SNMP-MIB::extNames.1 = STRING: check_raid
UCD-SNMP-MIB::extCommand.1 = STRING: /scripts/check_raid
UCD-SNMP-MIB::extResult.1 = INTEGER: 0
UCD-SNMP-MIB::extOutput.1 = STRING: OK: 3ware:[c0(9650SE-4LPML): u0:OK, (disks: p0:OK p1:OK p2:OK p3:OK)]
UCD-SNMP-MIB::extErrFix.1 = INTEGER: 0
UCD-SNMP-MIB::extErrFixCmd.1 = STRING:
Finally, you can integrate it as Nagios check using convenient for you method (for example with the help of 'retrieve custom snmp' plugin).
