Built-in Monitoring Packs

GridNMS ships with ready-made monitoring packs so that monitoring works the moment a device lands in the right class. A pack bundles the data points to collect (SNMP values, on a timer) and the tabs they add to the device detail page.

This page is a reference for the two bundles that ship out of the box:

  • Core bundle — vendor-neutral monitoring for routers, switches, servers, and UPSs.
  • UniFi bundle — Ubiquiti UniFi access points and cloud gateways.

Polling intervals below are how often each value is read. Counters (bytes, packets, errors) are read frequently and turned into per-second rates; descriptive values (system description, VLAN list) are read less often.


Vendor-neutral packs built on standard SNMP MIBs, so they work across most enterprise network gear.

Pack Target class Monitors Adds tabs
Core Network Network Devices Interfaces, traffic, errors, neighbors Interfaces · Neighbors · System Info
Core Router Router ARP, routes, BGP/OSPF peers, L2 neighbors ARP · Neighbors · BGP · OSPF · Routes
Core Switch Switch MAC address table, VLANs MACs · VLANs
Core Server Servers CPU, memory, disk Resources
Core UPS UPS Battery status, runtime UPS Status

The foundation pack for any SNMP device — per-interface throughput, packets, and errors, plus topology neighbor discovery.
