The Network Security appliance continuously gathers and reports relevant data about its utilization. There are recommended levels of utilization, known as rated limits, that are specific to each appliance model. Exceeding these limits can cause reduced malware detection efficacy, packet loss, and queuing errors.
You can use the utilization data as a tool for future capacity planning. When your appliance continuously or critically exceeds the rated limits, prominent messages and event notifications advise you to contact Trellix for guidance.
Utilization data and the associated rated limits are reported in the Appliance Utilization section on the Dashboard in the Web UI and in the show sizing stats CLI command output. On the Dashboard, you can view statistics for the current day, past week, or past month.
The Appliance Utilization section of the Network Security Dashboard includes a verdict that states the utilization zone your appliance is operating in (based on the most recent one-hour average) and recommended actions to take.
The Dashboard section also includes the following charts:
Utilization Summary shows the overall appliance utilization level.
MVX Web Analysis shows the Web pages waiting to be analyzed by the Network Security MVX engine, displayed as a percentage of capacity.
Total Bandwidth (Mbps) shows the total amount of traffic going through the monitoring ports, measured in Mbps. The thresholds are based on the rated bandwidth for the appliance.
In the following example, the appliance is operating in the good zone. Although it exceeded the rated limit for total bandwidth during the reporting period, it was back in the good range at the time the chart was rendered.
Monitor, Operator, or Admin access
