CPU Utilization can reflect the CPU that performs primary routing functions, or it might be an average of utilizations for all the CMTSs' CPUs. For some CMTS vendors, high CPU utilization adversely affects the performance of cable-modem data forwarding. This is a thresholded value and is displayed in different colors that represent the severity.
CPU Utilization Notes
Please note the following caveats for this graph type:
- By its nature, modem- and channel-based interactions do not apply to graphs of this item.
- Special selection ("strumming"), filtering by frequency, and hovering over a row in the Channels table have no effect on this graph.
- Modulation and channel distribution overlays do not apply.
- All channels in the MAC Domain are displayed, not just those channels used by the selected modem.
- The zoom function works the same as other graphs.
