| This ZenPack is only to be used with Cisco Catalyst switches that are running CatOS. It is not intended for monitoring IOS. Monitoring of Cisco switches running IOS can be accomplished using the default plugins/templates provided with Zenoss for monitoring Cisco routers. I personally copy the /Network/Router/Cisco class to /Network/Switch/Cisco and put my IOS switches in that class. I then put any CatOS devices in /Network/Switch/Cisco/Catalyst. |
Description:
The Cisco Catalyst ZenPack provides SNMP-based modeling and monitoring for Catalyst Switch devices running CatOS.
It consists of a modeler plugin called 'zenoss.snmp.InterfaceCatOsMap', which works in conjunction with 'zenoss.snmp.InterfaceMap' to properly map interfaces on Catalyst switches running CatOS.
It also comes with a performance template for monitoring CPU and Memory on Catalyst switches running CatOS.

Configuration:
The ZenPack has the following Device Class:
/Devices/Network/Switch/Cisco/Catalyst
Performance Template "Device":
/Devices/Network/Switch/Cisco/Catalyst/rrdTemplates/Device
Description:
Cisco template that collects cpu and free memory. Has CPU threshold at 90%
Datasources:
| DataSource | Datapoint |
|---|---|
| cpu5min | cpu5min |
| mem5minFree | mem5minFree |
| mem5minUsed | mem5minUsed |
| sysUpTime | sysUpTime |
Graph - CPU Utilization:
| Name | Type |
|---|---|
| CPU Threshold | ThresholdGraphPoint |
| CPU Utilization | DataPointGraphPoint |
Graph - Memory Utilization:
| Name | Type |
|---|---|
| Memory | ThresholdGraphPoint |
| Memory Utilization | DataPointGraphPoint |
| Total Memory | DataPointGraphPoint |
The following transform can be added to the /Perf/Memory class so that threshold messages display the percentage of utilization:
if dev.getRRDValue('mem5minUsed') and dev.getRRDValue('mem5minFree'):
percentUsed = round(dev.getRRDValue('mem5minUsed') * 100 / (dev.getRRDValue('mem5minUsed') + dev.getRRDValue('mem5minFree')))
if re.search('threshold of Memory exceeded', evt.summary):
status = 'exceeded'
if re.search('threshold of Memory restored', evt.summary):
status = 'restored'
evt.summary = "threshold of Memory %s: current value %3.1f" % (status,percentUsed)
evt.message = "threshold of Memory %s: current value %3.1f" % (status,percentUsed)
Installation Requirements:
- Zenoss Versions Supported: 2.5.2, 3.0.3
- External Dependencies: none
- ZenPack Dependencies: The /Devices/Network/Switch/Cisco class needs to be created by hand. I recommend copying /Devices/Network/Router/Cisco to that location. That way switches running IOS can be placed in /Devices/Network/Switch/Cisco and switches running CatOS can be placed in /Devices/Network/Switch/Cisco/Catalyst.
- Installation Notes: restart Zenoss to complete the installation.
