sitimechart

Hello,

While using sitimechart instead of timechart - The data has been changed.
I would like to calculate an error percentage but the system shows 0 or fields count.

Thanks!

If you would just like to make a timechart, then the timechart command should fit your need better than the sitimechart command. The sitimechart is intended for preparing the data to insert into a summary index so that later on it can be timecharted from the summary index.

Using just timechart:

<your search>
| timechart span=1d avg(errorPercentage) as errorPercentage by Process

If you would like to gather data now into a summary index to produce a timechart very quickly in a later search, you can use sitimechart:

<your search>
| sitimechart span=1d avg(errorPercentage) as errorPercentage by Process
| collect index=yoursummaryindex

Then in a later search:

index = yoursummaryindex <some filter, e.g. for Process=*>
| timechart span=1d avg(errorPercentage) as errorPercentage by Process

The docs page describes the sitimechart usage, but does not explain the meaning of the created fields: https://docs.splunk.com/Documentation/Splunk/9.2.0/SearchReference/Sitimechart
