Splunk Search

Show hourly count as zero if no data found for all indexes

I have a search:

| tstats count WHERE earliest=-2d@d latest=now index=* by index, _time | makecontinuous span=1h _time | fillnull value=0 count

If I search it by all indexes "*", no empty fields are shown.

If I search by a specific index that I know in fact is missing items, I get 0 for the count, and no index listed in the table.

How about this
| tstats count where index=* by _time span=1h | timechart span=1h max(count) as count | fillnull value=0 count

timechart by default (unless you specify fixedrange=f) creates a row for each time bucket from the beginning of the search period until the end of the search period. So, the timechart creates all the necessary rows, and then fillnull puts a 0 in all empty row.

that doesn't really do it by index though. I tried using timechart before but couldn't get it to specify by index.
