Have you tried installing the Agent as I had issues with Unbound until I installed the Agent

See below Steps
https://docs.librenms.org/Extensions/Agent-Setup/
Make sure that systemd or xinetd is installed on the host you want to run the agent on.


#6

We are using SNMP protocol for monitoring.

Also updated some information above , can you check?


#7

Me as well, but like I said I had issues with monitoring unbound until I installed the agent on the affected host.


#8

may be your your host was Linux , My problem is Juniper Firewall


#9

Fixed this problem by changing discovery and poller mempools for junos againt jnxOperatingMemory instead of jnxOperatingDRAMSize
