Learned Patterns Report

This Service Analytics report displays metrics associated with learned patterns such as the frequency of occurrence and the number of occurrences of the pattern identifier attributes in learned patterns (CI/MetricName by default). You can sort the learned patterns by pattern score, pattern frequency, and pattern size. This report helps you identify higher-frequency occurring alert patterns.

For each alert, alert aggregation combines the associated pattern identifier attributes that represent the alert. It then groups all the pattern identifier attributes for alerts that occur together, to create a learned pattern. The same combination of pattern identifier attributes can exist in multiple learned patterns. Typically, a learned pattern would indicate a single problem. The report displays metrics in a tile format broken by learned patterns.

To display the report, navigate to Service Analytics > Reports > Learned Patterns.

You can use this report to:
  • Allocate resources to the higher frequency occurring alerts to reduce the time for closing a large number of alerts.
  • Allocate resources to larger learned patterns of lower frequency.

Actions:

  • Select a tile to display further details about all the pattern identifier attributes that are associated with the selected tile.
    Column Description
    Configuration Item The configuration item used for the combined pattern identifier attributes.
    Metric Name The metric name used for the combined pattern identifier attributes.
    Frequency The number of times that the combined pattern identifier attributes occurs in the data set.
  • Hover over the pattern number to see the pattern size, pattern frequency, and pattern score details for the pattern.
  • Sort the report by:
    • Pattern Size: The number of combined pattern identifier attributes occurrences in a learned pattern.
    • Pattern Frequency: The number of times that a learned pattern occurs in the data set.
    • Pattern Score: Combined calculation of frequency and size, using the formula:

      Frequency * (Size + 1)

  • Click on a CI link in the Configuration Item column to display the CI form.
