centos 6 oid information for net-snmp

  • 772

I am trying to set up nagios core 3 to monitor linux servers using net-snmp, having trouble to find the correct oids for snmp.

mibDepot.com seems to be a good site, but I tried most of them, not working... Any suggestions where to look?

Thanks!

snmp nagios oid centos6

  1. If you have the snmpd installed on your Nagios server (running CentOS 6?) everything is already in place. Then you can start monitoring using the OID-names as well.

    Do a snmpbulkwalk -v 2c -c $COMMUNITY $TARGETSYS to dump a full snmp-listing of the target system.

  2. SNMP is good for network devices. For centos systems look at the nrpe daemon and client.

  3. I dont know what you're trying to do, but I'd start w/ nagios-plugins:

    [alexus@wcmisdlin02 ~]$ rpm -q nagios-plugins
nagios-plugins-1.4.15-2.el6.x86_64
[alexus@wcmisdlin02 ~]$

    then you can use following plugin to make snmp calls

    [alexus@wcmisdlin02 ~]$ /usr/lib/nagios/plugins/check_snmp 
check_snmp: Could not parse arguments
Usage:
check_snmp -H <ip_address> -o <OID> [-w warn_range] [-c crit_range]
[-C community] [-s string] [-r regex] [-R regexi] [-t timeout] [-e retries]
[-l label] [-u units] [-p port-number] [-d delimiter] [-D output-delimiter]
[-m miblist] [-P snmp version] [-L seclevel] [-U secname] [-a authproto]
[-A authpasswd] [-x privproto] [-X privpasswd]
[alexus@wcmisdlin02 ~]$

    I usually start from snmpwalk and then find right oid to check and take it to check_snmp nagios's plugin.
