Network Discovery
« on: August 23, 2018, 11:25:53 am »

Hi,

I have a structured network with 42 remote networks in vpn. I installed netxms on star-center and activated active and passive discovery. I detected 37 networks and relative devices on network out of 42. All the networks are reachable from the netxms server but, even after some time, I can not detect the missing ones. I have included the complete subnets of the remote networks in the discovery ranges.
Any suggestions ?

Hi,

there could be multiple reasons for that - firewall issues, no SNMP devices within subnets (needed for passive discovery), etc. Active discovery can take long time if subnets are big. You can try to set debug level to 6 and check messages with DiscoveryPoller prefix.

Best regards,
Victor
