Usage metrics and trends

You can monitor usage metrics for a specific device by clicking the Managed devices panel title from the Device management view, and then click the name of the device in the table to display the device details page. Usage metrics are graphically displayed on the Usage panel.

You can customize the panel to show data for metrics that interest you the most.
  • Memory. (default) Memory usage, as a percentage
  • Memory power consumption. Power consumption, in Watts, by all memory modules
  • Processors. (default) Processor usage, as a percentage
  • Processor power consumption Power consumption, in Watts, by all processors
  • Processor temperature. Temperature, in Celsius, for each processor
  • Power consumption. Power consumption, in Watts, by the device

Current usage metrics​

The Usage panel shows the amount available (pale color), highest usage (vivid color), and average usage (black diamond) for each component during the last hour.

Hover over the bar for each component to view more usage details, including the amount available, percentage of average usage, and percentage of maximum usage.
Usage panel
The bar color indicates whether the usage exceeds the thresholds.
  • Green. The actual usage is less than the warning threshold. The default threshold is 80% of the available amount.
  • Amber. The actual usage is between the warning and critical threshold.
  • Red. The actual usage is greater than the critical threshold. The default threshold is 90% of the available amount.

Data for each metric is kept for the last 90 days.

You can see the maximum usage trends over time by clicking the Usage panel title to display the Usage page. This page shows minimum, maximum, and average (black diamond) usage for each component over time. The color (green, amber, or red) indicates whether the maximum usage exceeds the thresholds.

Usage during the last hour is displayed by default. You can change the time span to show usage during the last 24 hours, 30 days, or 90 days. You can also scroll forwards and backwards in time, based on the selected period, using the scroll icons.

Tip
Data is aggregated and assigned to the next unit of time. For example, hourly data from 10:00 – 10:59 is aggregated and assigned to 11:00, and daily data from May 2 24:00 – 23:59 is aggregated and assigned to May 3.

Usage thresholds​

Usage thresholds are enabled by default. When enabled, an alert is raised when a component meets or exceeds its warning or critical threshold for the alert duration. The alert duration is the number of minutes during a specific period that the threshold value must be met or exceeded. For example, if processor temperature has a warning threshold of 80% and alert duration of 4 of 10 minutes, then an alert is raised when the processor temperature exceeds 80% for 4 or more minutes within a 10-minute period.

The minimum interval is 2 minutes within a 5-minute period.

You can set warning and critical usage thresholds and the alert duration for the certain components by clicking the Thresholds tab on context menu from the Settings view and then clicking the row for the component that you want to change.
