View metric values in the Metrics Explorer

Operational Metrics calculates aggregations and statistics for CIs metric data. The Metrics Explorer displays these metric values as metric charts for the CIs in the CMDB. The Metrics Explorer lets you overlap any metrics for any CIs in a single chart to create a multi-layered view of metric values across a time range.

About this task

The Metrics Explorer provides a canvas to which you can drag various metrics for CIs and create charts. You can place single metrics, each individually on the canvas. Or, you can layer several metrics for a single CI or for different CIs to create a multi-metric chart, each metric displaying in a unique color. This layering lets you compare metric values across CIs within the same time range. The Metrics Explorer provides a quick access to the 10 most anomalous CIs. However, you can add any CI from the CMDB that has metric data, and then add these CI metrics to the canvas.

As you create charts, a legend for the chart is automatically built underneath the chart. For a single-metric chart, the legend has entries for the aggregations in the chart. For a multi-metric chart, the legend has entries for the metrics in the chart.

Modifications in the Metrics Explorer remain during the session, and once the Metrics Explorer is refreshed it returns to its initial state.

Procedure

  1. Navigate to Event Management > Operational Metrics > Metric Explorer.
  2. Click a CI to drill down to its associated list of metrics ordered by their most recent anomaly scores.
    For each metric, a sparkline displays metric values for the CI for the last hour. Point to the sparkline to display the metric value at each point of time.
  3. Drag a metric to the Drop Metric To Create Chart area on the canvas. Point to the chart to display the exact metric value at each point of time. The metric chart displays data for the specified time period, according to the chart settings. By default, raw data is displayed, unless the time period is longer than a week or earlier than the last week, in which case average data is displayed instead.
    When you drag the second and then a subsequent metric, you can drop it on the canvas as follows:
    • In the Drop Metric To Create Chart area on the canvas so it is displayed individually in a new chart.
    • Onto an existing chart, in the Replace Chart highlighted block to overwrite the existing chart.
    • Onto an existing chart, in the Add Metric highlighted block to overlap it with the existing metrics in the chart.

      When you display multiple metrics in a single chart, the same aggregation selection applies to all the metrics, and statistics settings are not available. For example, if Average is selected in the Chart Settings, then averaged values are displayed for all the metrics in the chart.

  4. Click the Chart Settings icon to toggle the display of statistics and aggregations on the chart. Enabling or disabling an item to add or to remove metrics from a chart, also updates the chart's legend to reflect the change.
    Chart Setting Description
    Show Bounds Displays a computed upper and lower bound for the metric based on learning of past values. The upper and lower bounds always display together.
    Show Anomaly Scores Display anomaly scores on a virtual axis of 0-10. Color code is based on the score thresholds that are defined in the Anomaly Score to Event Severity Map [sa_metric_anomaly_score_to_event_severity_map] table.
    Average Display aggregated average metric values calculated per one hour periods.
    Aggregated averages are displayed as follows:
    • For data that is up to 28 days old: Displays 15-minutes aggregation windows.
    • For older data: Displays 1-hour aggregation windows.
    Minimum Display aggregated minimum metric values calculated per one hour time periods.
    Aggregated minimum values are displayed as follows:
    • For data that is up to 28 days old: Displays 15-minutes aggregation windows.
    • For older data: Displays 1-hour aggregation windows.
    Maximum Display aggregated maximum metric values calculated for one hour time periods.
    Aggregated maximum values are displayed as follows:
    • For data that is up to 28 days old: Displays 15-minutes aggregation windows.
    • For older data: Displays 1-hour aggregation windows.
    Raw Display the raw, unaggregated metric values. These values are kept only for the last week.
  5. Point to a legend item and click its 'X' icon to remove the corresponding metric from the chart, or to disable the corresponding series from the Chart Settings.

What to do next

  • Click Add Configuration Item to add to the Metrics Explorer any CI that is not displayed by default.
  • Click the Remove icon on a CI to remove it from the Metrics Explorer.
  • Zoom in or out by changing the Time Range selection. Select one of the preset time periods to display anomaly scores for the last 6 Hours or the last 1 Day for example, or specify a custom time period for up to 90 days back.

    Highlight a section of a chart by pointing to the upper left corner of the section and dragging the mouse device to the lower right corner of the section, to zoom in. This operation changes the time range of the chart, and if there are other charts on the canvas, they are all automatically synchronized to display data for the same time range. On the Time Range bar, the custom dates are also automatically updated with the new time range.

  • Add a filter to display only a specific set of CIs out of the CIs that are displayed.
  • Click the Export icon to download a chart as a .png or .svg image, or as a .pdf document.
