View metric values in the Metric Explorer

Operational Intelligence calculates aggregations and statistics for CI metric data. The Metric Explorer displays these metric values as metric charts for the CIs in the CMDB. The Metric 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 Metric Explorer provides a canvas to which you can drag various metrics for CIs and create charts. You can place a single metric on the canvas, for an individual metric for a CI. For a more comprehensive chart, you can layer several metrics for a single CI or for different CIs to create a multi-metric chart. In such layered chart, each metric is distinguished by a unique color, which lets you compare metric values across CIs within a specific time range.

Figure 1. Metric Explorer
Dashboard for Operational Intelligence metrics, where you can display charts for selected CI metrics.
To navigate to a CI for which to display metrics:
  • Use Hottest Configuration Items () to quickly access the 10 most anomalous CIs.
  • Use Pinned Configuration items () to create a separate custom list of any CIs from the CMDB and then add the metrics for these CIs to the canvas.
  • Use Business Services () to create a custom list of business services and manual services that let you drill into the CIs of these services. You can then add metrics for these CIs to the canvas.
  • Use CMDB Groups () to create a custom list of CMDB Groups that let you drill into the CIs of these groups. You can then add metrics for these CIs to the canvas.
Operational Intelligence uses the color settings for alert severities such as green, blue, yellow, orange, and red. Operational Intelligence does not track changes to an anomaly score if it is within the green band range. The colors of the dots at the upper left on the CI icons or the non-existence of a dot, signify the following:
  • Grey dot: Metrics are being tracked for the CI, but none of those metrics have ever had an anomaly.
  • Colored dot: Corresponds to the last recorded anomaly score according to the configuration of the color band ranges.
  • No dot: There are no metrics for the CI and there is no data to drill into.
    Note: Pinned Configuration items and Business Services are likely to include CIs for which there is no metric data.

As you create charts, a legend for each chart automatically appears 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 Metric Explorer remain during the session, and once the Metric Explorer is refreshed it returns to its initial state.

Procedure

  1. Navigate to Operational Intelligence > 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. If the time period is longer than a week or earlier than the last week, then average data is displayed.
    Drag subsequent metric to the canvas as follows:
    • In the Drop Metric To Create Chart area, 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. 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.
  5. 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 Displays 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 Displays aggregated average metric values calculated in one hour intervals.
    Aggregated averages are displayed as follows:
    • For data that is up to 8 days old: Displays 10-minute aggregation windows.
    • For data that is up to 94 days old: Displays 10-minutes aggregation windows.
    • For older data: Displays 1-hour aggregation windows.
    Minimum Displays aggregated minimum metric values calculated per one hour time periods.
    Aggregated minimum values are displayed as follows:
    • For data that is up to 8 days old: Displays 10-minute aggregation windows.
    Maximum Displays aggregated maximum metric values calculated for one hour time periods.
    Aggregated maximum values are displayed as follows:
    • For data that is up to 8 days old: Displays 10-minute aggregation windows.
    Raw Displays the raw, unaggregated metric values. These values are kept only for the last 8 days.

What to do next

  • Click Pinned Configuration items (), and then click Add Configuration Item to add to the Metric Explorer any CI that is not displayed by default.
  • Click Business Services (), and then click Add Business Service to add all CIs included in the specified business service.
  • Click CMDB Groups (), and then click Add CMDB Group to add all CIs included in the specified group.
  • Click Remove () next to a CI to remove it from the Metric Explorer.
  • Zoom in or out by changing the default Last Hour time range selection. Select one of the preset time periods to display anomaly scores for the last 6 Hours for example, or specify a custom time period for up to 90 days back.

    To zoom in, 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. The time range of the chart changes accordingly. If there are other charts on the canvas, they are all automatically synchronized to display data for the same time range. Also, the time range in the title bar automatically updates to reflect the new time range.

  • Right-click on a CI in the right-hand side bar and select View Form to open its CI form.
  • Click the Export icon in a chart to download it as a .png or .svg image, or as a .pdf document.
