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.
What Can Be Monitored
- per-card CPU busy/idle time and context-switch counts
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.
