Sample dashboards and layouts

This guide illustrates additional dashboard configurations you can create by using the Cloud Monitoring API. For additional examples, see Installable dashboards.

When to use the API

The Dashboard API provides you with a way of managing many dashboards at once. While you can use the Google Cloud Console to manage your dashboards, you may find it easier to use the API to manage your custom dashboards in bulk.

You also need to use the API if you want to add the Text, Scorecard, or blank placeholder widgets to your dashboard.

Dashboard layouts

Dashboard in GridLayout

This dashboard shows a GridLayout with three widgets.

Dashboards with Widgets

Dashboard with an XyChart

This dashboard shows a dashboard with a basic XyChart. If you ever used the Google Cloud Console to create charts on dashboards, those charts are instances of the XyChart widget.

Similar to the functionality provided in the Cloud Console, the API provides options to change the chart's PlotType or to configure the chart's view modes.

  "gridLayout": {
    "widgets": [
      {

Dashboard with a basic Scorecard

This dashboard shows a Scorecard without a gauge or sparkline. It shows the Compute Engine CPU utilization, and has two thresholds, one that uses the color yellow to indicate that CPU utilization is over 70%, and one that uses red to indicate that the CPU utilization is over 90%.

Because the current CPU utilization falls below the specified thresholds, it is considered a pass.

{
  "displayName": "Unadorned scorecard",
  "gridLayout": {
    "widgets": [
      {
        "title": "Compute Engine CPU utilization",
        "scorecard": {
          "timeSeriesQuery": {
            "timeSeriesFilter": {
              "filter": "metric.type=\"compute.googleapis.com/instance/cpu/utilization\" resource.type=\"gce_instance\"",
              "aggregation": {
                "perSeriesAligner": "ALIGN_MEAN",
                "crossSeriesReducer": "REDUCE_MAX",
              }
            },
            "unitOverride": "1"
          },
          "thresholds": [
            {
              "color": "RED",
              "direction": "ABOVE",
              "label": "Danger",
              "value": 0.9,
            },
            {
              "color": "YELLOW",
              "direction": "ABOVE",
              "label": "Warning",
              "value": 0.7,
            }
          ]
        }
      },
    ]
  }
}

The dashboard looks similar to the following example:

Example dashboard with a Scorecard widget

Dashboard with a Scorecard with GaugeView

This dashboard adds a gauge to the basic scorecard in the previous example. The GaugeView object can specify an upper and a lower bound, to specify the range of values to show on the gauge. Since the scorecard shows values from 0 to 1, those are reasonable upper and lower bounds. To add the gauge, add the following to the JSON for the basic scorecard:

          "gaugeView": {
            "lowerBound": 0,
            "upperBound": 1,
          },

The following shows the complete modified dashboard specification: The current value is under the thresholds, which are colored appropriately on the gauge.

{
  "displayName": "Gauge scorecard",
  "gridLayout": {
    "widgets": [
      {
        "title": "Compute Engine CPU utilization",
        "scorecard": {
          "timeSeriesQuery": {
            "timeSeriesFilter": {
              "filter": "metric.type=\"compute.googleapis.com/instance/cpu/utilization\" resource.type=\"gce_instance\"",
              "aggregation": {
                "perSeriesAligner": "ALIGN_MEAN",
                "crossSeriesReducer": "REDUCE_MAX",
              }
            },
            "unitOverride": "1"
          },
          "gaugeView": {
            "lowerBound": 0,
            "upperBound": 1,
          },
          "thresholds": [
            {
              "color": "RED",
              "direction": "ABOVE",
              "label": "Danger",
              "value": 0.9,
            },
            {
              "color": "YELLOW",
              "direction": "ABOVE",
              "label": "Warning",
              "value": 0.7,
            }
          ]
        }
      },
    ]
  }
}

The dashboard looks similar to the following example:

Example dashboard with a Scorecard widget with GaugeView

Dashboard with a Scorecard with SparkChartView

This dashboard replaces the gauge in the previous example with a sparkline. The SparkChartView object can create line charts or bar charts on a scorecard. This example uses a line. As long as the value doesn't violate a threshold, it is green. To add the sparkline, replace the gaugeView JSON object in the previous chart with the following:

          "sparkChartView": {
            "sparkChartType": "SPARK_LINE"
          },

The dashboard looks similar to the following example:

Dashboard with a Text widget

This example shows a simple dashboard with a Text widget.

{

    "widgets": [
      {
        "text" {
          "content": "Hello World"
        }
      }
    ]
  }
}

The dashboard looks similar to the following example:

Dashboard with a blank widget

This example shows a simple dashboard with an empty, placeholder widget. Note that only the dashboard's displayName appears in the widget.

{
  "displayName": "Demo Dashboard",
  "gridLayout": {
    "widgets": [
      {
        "blank": {}
      }
    ]
  }
}
