I have the same problem/requirement.
What I want to do is to have predictions for counts of events in the timechart that is split by country, using trellis chart. Is there a way? The normal BY clause doesn't output anything when adding PREDICT
Thanks but the example did not support an actual by-clause
| stats count by sourcetype
| map search="search index=_internal sourcetype=$sourcetype$ | timechart count as $sourcetype$ | predict $sourcetype$"
| stats values(*) as * by _time
I need predict to support "timechart count as $sourcetype$ by host" for example.
