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, printers, and UPSs — nothing to download, nothing to install. For specific vendors — Cisco, Juniper, Fortinet, Palo Alto, Aruba, APC, and dozens more, plus an API-based integration for Cisco Meraki — download a vendor pack bundle instead.

Built in vs. downloaded

Everything on this page is already installed and applies the moment a device lands in the matching class — there’s nothing to upload or import. A vendor pack bundle is different: it’s an optional download that adds vendor-specific extras (CPU, memory, environment sensors, and so on) on top of what’s already here. Packs apply through device classes either way — put a device in a class (or let discovery classify it), and every pack attached to that class is inherited automatically. You can enable, disable, or tune individual data points per class — see Enabling & Disabling Data Points.

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

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

Pack	Target class	Monitors	Adds tabs
Core Network	All Classes	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 Printer	Printer	Supply levels, trays, output bin, page counts, cover/marker status	Supplies · Trays · Output & Covers · Usage · Status

Core Network

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

It is attached to the All Classes root, so every device class inherits it and any SNMP device gets interface metrics without you attaching anything. The data points below come from standard MIB-2, which effectively every SNMP device implements — including printers, servers, and appliances that have no vendor pack of their own.

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

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

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

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

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

Core Printer

Standards-based monitoring for any network printer — HP, Brother, Canon, Xerox, and generally any make or model that speaks the Printer MIB (RFC 3805) and Host Resources MIB, which is nearly all of them. There’s no vendor-specific bundle to download for printers; this is the whole story.

Data point	Type	OID	Interval
Printer Status	SNMP walk	1.3.6.1.2.1.25.3.5.1.1	2 min
Device Status	SNMP walk	1.3.6.1.2.1.25.3.2.1.5	2 min
Supply Name / Level	SNMP walk	1.3.6.1.2.1.43.11.1.1.6 / .9	5 min
Supply Max Capacity	SNMP walk	1.3.6.1.2.1.43.11.1.1.8	10 min
Input Tray Name / Media / Level / Max Capacity / Status	SNMP walk	1.3.6.1.2.1.43.8.2.1.13 / .12 / .10 / .9 / .11	5 min
Output Bin Name / Capacity / Status	SNMP walk	1.3.6.1.2.1.43.9.2.1.7 / .4 / .6	5 min
Cover Status	SNMP walk	1.3.6.1.2.1.43.6.1.1.3	2 min
Marker Status	SNMP walk	1.3.6.1.2.1.43.10.2.1.15	2 min
Lifetime Page Count	SNMP walk	1.3.6.1.2.1.43.10.2.1.4	5 min
Power-On Page Count	SNMP walk	1.3.6.1.2.1.43.10.2.1.5	10 min
Console Alert Lights	SNMP walk	1.3.6.1.2.1.43.17.6.1.4	2 min

Supply levels report per cartridge (toner, ink, drum, and so on — however many the printer has), so a multi-color printer reports each color separately. Trays and output bins are the same shape: one reading per physical tray or bin the printer reports. Interface traffic for a printer’s network port comes from Core Network, which every class inherits automatically.

Customizing or extending

Built-in packs are a starting point, not a limit. You can:

• Tune any data point’s interval or disable it per class — see Enabling & Disabling Data Points.
• Add a vendor — import a ready-made bundle for Cisco, Juniper, Fortinet, Palo Alto, MikroTik, F5, Synology, and dozens more — including an API-based bundle for Cisco Meraki — see Vendor Pack Bundles.
• Build your own pack for hardware not covered here — see Building a Monitoring Pack.
• Set thresholds on any collected metric to raise events — see Events & Alerts.
