I am running Zenoss Core 4.2 and had been running SNMP v2c to monitor Red Hat workstations. I have since switched over to SNMP v3, but now have alarms coming in saying that "SNMP agent down", "unable to read processes on device" and "does not publish HOST-RESOURCE-MIB". I can SNMP v3 walk locally on the host as well as on my Zenoss server. I can model the host as well. When I look at the performance data, all the stats show "-nan" so I'm not getting those data points.
When I added SNMP v3 I ran the following:
service snmpd stop
net-snmp-create-v3-user -ro -A snmpv3authPass -a SHA -X snmpv3encPass -x AES snmpv3user
service snmpd start
The output then showed:
adding the following line to /var/lib/net-snmp/snmpd.conf:
createUser snmpv3user SHA "snmpv3authPass" AES snmpv3encPass
adding the following line to /etc/snmp/snmpd.conf:
rouser snmpv3user
I also updated the following fields in Zenoss:
- zSNMPAuthPassword
- zSnmpAuthType
- zSnmpPrivPassword
- zSnmpPrivType
- zSnmpSecurityName
Do I need to additional updates or configuration changes? Did I miss something? Thanks for your help in advance!
