Graph a Metric

You can select metrics and create graphs of the data using the CloudWatch console.

CloudWatch supports the following statistics on metrics: Average, Minimum, Maximum, Sum, and SampleCount. For more information, see Statistics.

You can view your data at different granularities. For example, you can choose a detailed view (for example 1 minute), which can be useful when troubleshooting. You can choose a less detailed view (for example, 1 hour), which can be useful when viewing a broader time range (for example, 3 days) so that you can see trends over time. For more information, see Periods.

Create a Graph

To graph a metric

  1. Open the CloudWatch console at https://console.aws.amazon.com/cloudwatch/.

  2. In the navigation pane, choose Metrics.

  3. On the All metrics tab, type a search term in the search field, such as a metric name or resource name, and press Enter.

    For example, if you search for the CPUUtilization metric, you see the namespaces and dimensions with this metric.

  4. Select one of the results for your search to view the metrics.

  5. To graph one or more metrics, select the check box next to each metric. To select all metrics, select the check box in the heading row of the table.

  6. To view more information about the metric being graphed, hover over the legend.

  7. Horizontal annotations can help graph users quickly see when a metric has spiked to a certain level, or whether the metric is within a predefined range. To add a horizontal annotation, choose Graph options, Add horizontal annotation:

    1. For Label, type a label for the annotation.

    2. For Value, type the metric value where the horizontal annotation appears.

    3. For Fill, specify whether to use fill shading with this annotation. For example, choose Above or Below for the corresponding area to be filled. If you specify Between, another Value field appears, and the area of the graph between the two values is filled.

    4. For Axis, specify whether the numbers in Value refer to the metric associated with the left Y-axis or the right Y-axis, if the graph includes multiple metrics.

      You can change the fill color of an annotation by choosing the color square in the left column of the annotation.

    Repeat these steps to add multiple horizontal annotations to the same graph.

    To hide an annotation, clear the checkbox in the left column for that annotation.

    To delete an annotation, choose x in the Actions column.

  8. To get a URL for your graph, choose Actions, Share. Copy the URL and save it or share it.

  9. To add your graph to a dashboard, choose Actions, Add to dashboard.

Update a Graph

To update your graph

  1. To change the name of the graph, choose the pencil icon.

  2. To change the time range, select one of the predefined values or choose custom. For more information, see Modify the Time Range for a Graph.

  3. To change the statistic, choose the Graphed metrics tab. Choose the column heading or an individual value, and then choose one of the statistics or predefined percentiles, or specify a custom percentile (for example, p95.45).

  4. To change the period, choose the Graphed metrics tab. Choose the column heading or an individual value, and then choose a different value.

  5. To add a horizontal annotation, choose Graph options, Add horizontal annotation:

    1. For Label, type a label for the annotation.

    2. For Value, type the metric value where the horizontal annotation appears.

    3. For Fill, specify whether to use fill shading with this annotation. For example, choose Above or Below for the corresponding area to be filled. If you specify Between, another Value field appears, and the area of the graph between the two values is filled.

    4. For Axis, specify whether the numbers in Value refer to the metric associated with the left Y-axis or the right Y-axis, if the graph includes multiple metrics.

      You can change the fill color of an annotation by choosing the color square in the left column of the annotation.

    Repeat these steps to add multiple horizontal annotations to the same graph.

    To hide an annotation, clear the checkbox in the left column for that annotation.

    To delete an annotation, choose x in the Actions column.

  6. To change the refresh interval, choose Refresh options, and then select Auto refresh or choose 1 Minute, 2 Minutes, 5 Minutes, or 15 Minutes.

Duplicate a Metric

To duplicate a metric

  1. Choose the Graphed metrics tab.

  2. For Actions, choose the Duplicate icon.
