Description: Monitors CPU process utilization and system process management on ARRIS/Cadant CMTS platforms.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is CADANT-CMTS-PROCESS-MIB?

CADANT-CMTS-PROCESS-MIB is an Arris (formerly Cadant) proprietary MIB reporting CPU process-table and utilization data on the Cadant C4 CMTS. Its per-card CPU table reports recent and total busy time alongside recent and total idle time and idle-time percentage, plus context-switch counts. As a hardware/software-status MIB it lets an administrator watch per-card CPU idle percentage to catch a control-plane card approaching CPU exhaustion before it affects service. It is deployed on Arris/Cadant C4 CMTS platforms in cable operator head-ends. Engineers can download the CADANT-CMTS-PROCESS-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CADANT-CMTS-PROCESS-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Supported Devices

Arris (Cadant) C4 CMTS

Monitoring Examples

An administrator monitors cadIdleCpuRecentPercent per card to catch a CMTS control card trending toward CPU exhaustion before it starts delaying cable modem registration or provisioning.

How to Use in IPNetwork Monitor

Example using cadCpuRecentTime OID:

Select an ARRIS/Cadant C4/E6000 CMT (cable modem termination system) as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type cadCpuRecentTime into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. It reports the total CPU time consumed in the last reporting cycle. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is a Counter64-type OID, Value bounds is the most useful condition here — trigger an alert if utilization exceeds 85%, a common warning threshold before sustained high load affects performance. Click Finish to create the monitor; you can adjust any parameter later.
