Re: Please check the data collection configuration for this node.

I have a few nodes that just have ICMP configured. When I go to node and select resource graphs I can graph the latency of the pings for that device. Even this functionality doesn't work for the switch. It appears to be connected to HP Procurve switches as I've added a second node for a switch in one of our warehouses and it exhibiting the same behavior.

I am running version 22.0.2 of Opennms. Unfortunately I don't fully understand your second question.

Hi Robert,

without configuring SNMP you probably won't see graphs for your device. Unless it's some very unusual system all network devices use SNMP for data collection. You wrote that snmp walk is working and that you already had defined the snmp community in opennms but removed it now. I would propose to add it again and then try

tail -f provisiond.log

followed by a rescan of the node (from the node's page in the GUI). There should be entries in provisiond.log when opennms tries to contact the node using snmp. If this is working, then check collectd.log. You may probably need to search for the nodes nodeid or his primary IP address. You can also check the DB how the node is defined

echo "select * from node where nodeid=xxx;" |psql
echo "select * from ipinterface where nodeid=xxx;" |psql

The first query is just to be sure you have the correct device. The  output from the second sql statement should show the IP you use for polling the node, e.g. for which you defined the snmp community, and issnmpprimary should have the value 'P'.

BTW:

-       What version of opennms are you working with?

-       Is there a package in datacollection-config, in collectd defining the data you want to have and is the node in the correct package, defined by ip or category or something else?
