Warning

The DevOps Portal has been deprecated in the Q4`18 MCP release tagged with the 2019.2.0 Build ID.

The Heatmaps dashboard provides the information about resource consumption by the cloud environment identifying the load of each node and number of alerts triggered for each node. The dashboard includes heatmaps for the following data:

  • Memory utilization

  • CPU utilization

  • Disk utilization

  • Alerts triggered

Note

The Heatmaps dashboard depends on the following services:

  • DevOps Portal web UI

  • Prometheus service of StackLight LMA

To use the Heatmaps dashboard:

  1. Log in to the DevOps Portal.

  2. Navigate to the Heatmaps dashboard.

  3. Switch between the tabs to select a required heatmap.

    Each box on a heatmap represents a hypervisor. The box widget is color-coded:

    • Green represents a normal load or no alerts triggered

    • Orange represents a high load or low number of alerts

    • Red represents an overloaded node or a high number of alerts

  4. Specify the parameters for the data to be displayed:

    • Use Now, Last 5m, Last 15m, and Last 30m buttons to view data for a specific time period.

    • Use the Custom button to set custom time period. The time value format includes the number from 1 to 99 and a metric prefix that is m for minutes, h for hours, d for days, and w for weeks. For example, 12h, 3d, and so on.

    • Use the Max button to display a maximum value of resources consumption or number of alerts during the selected period of time.

    • Use the Avg button on the Memory, CPU, and Disk tabs to display an average value of resources consumption during the selected period of time.

    • Use the Diff button on the Alerts tab to display the count of alerts triggered since the selected period of time.

      Note

      On the Alerts tab, the 0 count of alerts means that either 0 alerts are triggered or Prometheus failed to receive the requested data for a specific node.
