Server Heatmap

The Server Heatmap widget is used for visualizing the availability of individual servers. Optionally set which metrics to take into account for the availability of the server or leave it blank for all. Cells will remain green if the current status is healthy, otherwise red or orange depending on the severity of an active incident for that server. Hovering over the cell will provide details on that instance. Like most widgets, you can scope the results to specific instances using a variety of filtering options.

The Server Heatmap widget is useful when:

  • You want to quickly view the current health of the instances on an instance group.

Examples
