By "Search Criteria" and given the comment, I'm guessing you mean the timerange of a search, which you could add to another panel(s) (single value perhaps?) using an additional search. Now since since you cannot have a shared time picker and generate a PDF dashboard, there is some additional work on you the dashboard creator to ensure that the time range of this new search, matches the time ranges of the other searches of the dashboard:
| noop | stats count
| addinfo
| convert timeformat="%FT%T" ctime(*_time)
| eval value = info_min_time. " -> ". info_max_time
| fields value
How this search works line by line is as follows:
| noop | stats count
is a trick to create a search with a single result, using the undocumented "do nothing" noop
command followed by using stats to count that nothing. (There are other documented ways to accomplish a similar result but noop
is a personal favorite )This is a brilliant question and I have been trying to find the answer for this for some time now.
What is the first thing people look at when you hand them the report, the period that the report is generated for???
Unfortunately, it appears that Splunk cannot perform this very very very basic requirement, poor poor poor.
