diagnostic extract

In CloudBees CD, a diagnostic extract is a log file portion from a job step, typically describing an error or interesting condition, extracted by a postprocessor and saved for reporting. The postprocessor usually places this information in an XML file in the top-level job workspace directory, and then sets a property that contains the file name. The CloudBees CD postp postprocessor uses file names like diag-2770.xml, where 2770 is the unique identifier for the step. Other postprocessors you may use have a different file name configuration.
