Analyzing log records

Analyzing log records means to compare log records using specified symptom databases that are loaded in memory. The Log and Trace Analyzer provides a default log analyzer which takes data from a log file, compares it to rules or a set of rules in a symptom database, and returns an array of objects representing the solutions and directives for the matched symptoms. Once a log file is analyzed, the solution is reported in the Analysis Result pane, giving the customer advice on resolving the reported problem.

  1. To analyze a particular log record, in Log view, select it from the list of Log Records.
  2. Right-click, then select Analyze > Default Log Analyzer.
  3. To analyze multiple log records, use the CTRL key to select the records. Right-click and select Analyze > Default Log Analyzer.
  4. To analyze all log records, right-click, then select Analyze All > Default Log Analyzer
  5. If a match is found in the symptom database, the record is highlighted in blue and the solution information appears in the Analysis Result tab:

    analysis result tab selected on left side and analysis result (directive) displayed on right side

Note: The Log and Trace Analyzer provides a set of tools that can be used to implement additional log analyzers that can be plugged into the workbench and used within the Log and Trace Analyzer. See the document on Creating an Analysis Engine.
