Summary indexing is a method you can use to speed up long-running searches that do not qualify for report acceleration, such as searches that use commands that are not streamable before the transforming command. For more information, see "About report accelleration and summary indexing" and "Use summary indexing for increased reporting efficiency" in the Knowledge Manager Manual.
sitimechart command is the summary indexing version of the
timechart command, which creates a time-series chart visualization with a corresponding table of statistics. The
sitimechart command populates a summary index with the statistics necessary to generate a timechart report. After you use an
sitimechart search to populate the summary index, use the regular
timechart command with the exact same search string as the
sitimechart search to report against the summary index.
The required syntax is in bold.
- [<bin-options>... ]
- <single-agg> [BY <split-by-clause>] | <eval-expression> BY <split-by-clause>
sitimechart command arguments, either <single-agg> or <eval-expression> BY <split-by-clause> is required.
For descriptions of each of these arguments, see the timechart command.
You can use a wide range of functions with the
sitimechart command. For general information about using functions, see Statistical and charting functions.
collect command to populate a summary index called
mysummary with the statistics about CPU usage organized by host,
... | sitimechart avg(cpu) BY host | collect index=mysummary
collect command adds the results of a search to a summary index that you specify. You must create the summary index before you invoke the
Then use the
timechart command with the same search to generate a timechart report.
index=mysummary | timechart avg(cpu) BY host
