Usually I insert a node in OpenNMS and then I enable the SNMP on the "Client" (install the client, the security part , restart it and that's it). What happens is that sometimes even if SNMP is working (the SNMP poller is Green), I need to restart OpenNMS if I want to view graphs. Is this the normal behavior?
Is there a way to have graphs without restarting OpenNMS? (update snmp or rescan did not work for me). When I restart OpenNMS I get many threasholds alert and it's a bit painy to restart it ;)
