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 Core bundle that ships out of the box: vendor-neutral monitoring for routers, switches, servers, and UPSs. For specific vendors (Cisco, Juniper, Palo Alto, and more), download a vendor pack bundle.

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.

Core bundle

Section titled “Core bundle”

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

Core Network

Section titled “Core Network”

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

Data point Type OID Interval
System Description SNMP get 1.3.6.1.2.1.1.1.0 5 min
Interfaces (ifTable) SNMP walk 1.3.6.1.2.1.2.2 5 min
Interface Rx/Tx Bytes (64-bit) SNMP walk 1.3.6.1.2.1.31.1.1.1.6 / .10 1 min
Interface Rx/Tx Bytes (32-bit) SNMP walk 1.3.6.1.2.1.2.2.1.10 / .16 5 min
Interface Rx/Tx Packets SNMP walk 1.3.6.1.2.1.2.2.1.11 / .17 1 min
Interface Rx/Tx Errors SNMP walk 1.3.6.1.2.1.2.2.1.14 / .20 1 min
CDP Neighbors SNMP walk 1.3.6.1.4.1.9.9.23.1.2.1.1 5 min
LLDP Neighbors SNMP walk 1.0.8802.1.1.2.1.4.1.1 5 min

Discovered CDP/LLDP neighbors feed the Topology & Neighbors views.

Core Router

Section titled “Core Router”

Layer-3 visibility on top of Core Network: the ARP and routing tables plus dynamic routing-protocol peers.

Data point Type OID Interval
ARP Table SNMP walk 1.3.6.1.2.1.4.35.1 5 min
Routes SNMP walk 1.3.6.1.2.1.4.21.1 5 min
BGP Peers SNMP walk 1.3.6.1.2.1.15.3 1 min
OSPF Neighbors SNMP walk 1.3.6.1.2.1.14.10 1 min
LLDP Neighbors SNMP walk 1.0.8802.1.1.2.1.4.1.1 5 min
CDP Neighbors SNMP walk 1.3.6.1.4.1.9.9.23.1.2.1.1 5 min

Core Switch

Section titled “Core Switch”

Layer-2 tables for switches.

Data point Type OID Interval
MAC Address Table SNMP walk 1.3.6.1.2.1.17.4.3.1 5 min
VLANs SNMP walk 1.3.6.1.2.1.17.7.1.4.3 5 min

Core Server

Section titled “Core Server”

Host resource monitoring via the standard UCD-SNMP MIB (Net-SNMP).

Data point Type OID Interval
CPU Load SNMP get 1.3.6.1.4.1.2021.10.1.3.1 1 min
Memory Free SNMP get 1.3.6.1.4.1.2021.4.6.0 1 min
Disk Free Space SNMP get 1.3.6.1.4.1.2021.9.1.7.1 5 min

Core UPS

Section titled “Core UPS”

Battery health via the standard UPS MIB.

Data point Type OID Interval
Battery Status SNMP get 1.3.6.1.2.1.33.1.2.1.0 2 min
Runtime Remaining SNMP get 1.3.6.1.2.1.33.1.2.3.0 2 min
