I have version
I executed the following:
sp_blitzfirst @ExpertMode = 1, @CheckProcedureCache = 1, @OutputType = 'Opserver1'
Below output shows SPID 124 is blocked by SPID 143, however SPID 143 did not show up in any of the output. Is there another way to have sp_BlitzFirst show the info of the blocking_sesesion_id as well, so I can see what query is being executed?
