1-would you please explain more, I enable embedded report, and summary index for my report and splunk give me a link of that report. what should I do in next step?
2-How put it on dashboard?
3-what happen every time this schedule report run? does it consume disk or cleanup data after summary report generated?
I also check summary index noting there!
to embed report, you have to follow the steps described in the above link, in othe words, put the link in your dashboard.
Summery report use disk space, but not so much, anyway can configure a low retency on your summary index (e.g. 24 hours) so this isn't a problem.
results of the scheduled report are saved in the dispatched folder and they remain there until the validity of these results (usually 24 hours).
About results in the summary indexes, check the scheduled search:
you can see the last execution time and the results of this running; in addition you can manually execute it.
If you continue to have any results, check the search execution (the full search without the last row), with special attention to the time frame that you're using.
