A Windows system resource monitor has been implemented within Altium NEXUS. When resource consumption gets to a level considered to be high, a resource warning indicator appears at the bottom-right of Altium NEXUS. Hover the cursor over the indicator for information about which resource(s) are exceeding associated levels of consumption. Note that the color of the indicator changes to highlight the level of resource consumption.

A warning indicator appears when Altium NEXUS's resource consumption becomes high, and changes color to indicate when action is required.A warning indicator appears when Altium NEXUS's resource consumption becomes high, and changes color to indicate when action is required.

The following resources are monitored:

  • Memory used by Altium NEXUS
  • Count of allocated GDI handles
  • Percentage of allocated global and session atoms

The resource monitor triggers and displays a warning indicator when any of the above resources reach the following levels:

  • < 60% normal level (no resource indicator is displayed)
  • 61% to 75% is considered a high level, indicated by a yellow indicator
  • 76% to 90% is considered a very high level, indicated by an orange indicator. In addition, the message indicates that a restart of Altium NEXUS is advisable.
  • > 90% is considered a critical level, indicated by a red indicator. In addition, the message indicates that a restart of Altium NEXUS is advisable.
Only resources that have exceeded the permissable levels will be included in the hover tip message.
It is important to be aware that Windows has a default limit of 10000 GDI handles available per application, it is strongly recommended that you restart Altium NEXUS when advised to do so.
