1.4 Using NetworkDevice Scripts

The AppManager for Network Device module provides Knowledge Scripts that can monitor and retrieve statistics about Ethernet interfaces and protocols from the MIB2 (management information base) of the Call Server, Media Gateway, Signaling Server, Media Gateway Controller, and VGMC.

In addition to using the Knowledge Scripts in the Nortel CS category, you can enhance your monitoring efforts by including the following Knowledge Scripts from the NetworkDevice category:

Knowledge Script

What It Does

NetworkDevice_Device_Ping

Checks the availability of network devices that respond to ICMP Echo requests.

NetworkDevice_Host_CPULoaded

This script monitors Nortel CS1000 version 4.50 Media Gateways only.

Accesses the Host Resource MIB to monitor total CPU usage to determine whether the CPU is overloaded.

  • Call Server Do not run this script on a Call Server — it will monitor call capacity usage rather than CPU usage. In version 4.50 devices, the MIB value for the CPU processor load represents call capacity usage. To monitor call capacity usage, use the NortelCS_CallCapacity Knowledge Script.

  • Media Gateway The hrProcessorload value in the MIB is always -1, so the data stream value for this script is always 0.

NetworkDevice_Host_DeviceStatus

This script monitors CS1000 version 4.50 and later devices only.

Accesses the Host Resource MIB to monitor the status and error count for Co-resident Servers, Call Servers, Media Gateways, VGMCs, Signaling Servers, and SIP Gateways.

NetworkDevice_Host_MemoryUsage

Accesses the Host Resource MIB to monitor memory usage on CS1000 version 4.50 and later Co-resident Servers, VGMCs, Signaling Servers, and SIP Gateways.

NetworkDevice_Host_ProcessDown

Accesses the Host Resource MIB to determine whether a specified process is not running on CS1000 version 4.50 and later Co-resident Servers, Call Servers, Media Gateways, VGMCs, Signaling Servers, and SIP Gateways.

NetworkDevice_Host_ProcessUp

Accesses the Host Resource MIB to determine whether a specified process is running on CS1000 version 4.50 and later Co-resident Servers, Call Servers, Media Gateways, VGMCs, Signaling Servers, and SIP Gateways.

NetworkDevice_Host_StorageUsage

This script monitors CS1000 version 4.50 and later devices only.

Accesses the Host Resource MIB to monitor storage usage on the following devices.

  • Call Server This script monitors flash memory storage.

  • Media Gateway This script monitors flash memory storage.

  • VGMC This script monitors floppy disk storage. Flash memory is implemented on the VGMC Host MIB, but the value is always -1, so the data stream value for this script is always 0.

  • Signaling Server This script monitors fixed disk, compact disk, and floppy disk storage.

  • MGC This script monitors fixed disk storage.

  • Linux base server This script monitors Linux file systems for CS1000 version 6.0.

NetworkDevice_Interface_Health

Monitors the parent resource for the interfaces on a network device.

NetworkDevice_IPSubsystem_Util

Monitors the IP subsystem of a network device.

NetworkDevice_LANLink_Util

Monitors the parent resource for the LAN links on a network device.
