For some reason, I get alarms on nodes that are down. On a daily basis (every night around 02:30) I get one uei.opennms.org/nodes/dataCollectionFailed for each of these nodes.
SNMP data collection on interface x.x.x.x failed with 'Timeout retrieving SnmpCollectors for x.x.x.x for / x.x.x.x: SnmpCollectors for x.x.x.x: snmpTimeoutError for: / x.x.x.x '.
I want to keep these "dead" nodes in the database since they might be switched back on again. It’s not a big issue but since I really like the “Nodes with Pending Problems” box, it’s annoying.
What have I missed in the configuration?
