I have a saved search that has a time range of All time. The saved search contains eval and stats functions that I want to apply to certain time ranges only. The saved search is All time because I need to generate the FirstSeen date of an event in the report. I've found I cannot do this and no Statistics are generated.
Example saved search: index="log" | eval Label= case((status="0"),"Other" | stats earliest(_time) as FirstSeen, latest(_time) as LastSeen count values by host Label
When I reference this saved search in another report and specify a time range, in this case the last hour on the hour – no stats are generated.
|savedsearch "Master Report" | where _time>=relative_time(now(), "-1h@h") AND _time<=relative_time(now(), "@h") | table host Label FirstSeen LastSeen
Is it not possible to filter for time ranges when referencing a saved search that has a stats command?
you can apply filter also in the second part of your search adding the command (e.g. appliang a filter to the last seven days):
| seacrh earlies=-7d latest=now
But this solution isn't very performat, indeed it is not recommended because best practices suggest to use always the as short as possible time period!
So I suggest to schedule a search that e.g. every hour or every day (it depends by your data update frequency) writes the results of the "FirstSeen date" in a summary index, so you can use the correct time period for your search and add the value from the summary index, or you can schedule the full search and use its results only from the summary index that is little and very performant.
