Zabbix SNMPv2 Netgear Switching monitoring

Monitors Netgear Switching parameters (fastPathSwitching), currently only CPU, memory and spanning tree protocol information exposed by the NETGEAR-SWITCHING-MIB via SNMPv2.

This template is part of RaBe's Zabbix template and helpers collection.

Usage

Download the NETGEAR-SWITCHING-MIB and its dependencies (should be present within the MIB package of your Netgear device)
Place the MIB file(s) into your default MIB directory on the Zabbix server and/or proxy (usually /usr/local/share/snmp/mibs) and make sure that the Zabbix server and/or proxy loads them (see Using and loading MIBs).
Import the Template_SNMPv2_Netgear_Switching.xml into your Zabbix server (click on the Raw button to download).
Add an SNMP interface configuration to your host
Set the {$SNMP_COMMUNITY} macro to your desired community if you don't use public
Add the template to your host (or stack template)
Check if new data arrives

Notes

snmpwalk command

The following snmpwalk command might be helpful for debugging:

snmpwalk -v 2c -c public <HOST> NETGEAR-SWITCHING-MIB::fastPathSwitching

CPU utilization

The CPU utilization is currently only available as a string with 5, 60 and 300 second values (5 Secs ( 13.2483%) 60 Secs ( 11.3541%) 300 Secs (11.2930%) which makes it very hard or impossible to create triggers.

Please open up an issue if you know of an elegant way to either parse and split the item into separate float items or if you find other OIDs which separately expose the values - thanks.

Discovery

Multiple spanning tree protocol instances (`agentStpMstId.discovery`)

Discovery of multiple spanning tree protocol instances (STP MST), including the common and internal spanning tree instance 0.

Item Prototypes
