Which AQL query, when run from IBM Security QRadar SIEM V7.2.8, will show EPS broken down by domains?

  • A. select DOMAINNAME (domainid) as LogSource, sum(eventcount) / ((max(endTime) min(startTime)) / 1000 ) as EPS from events group by domainid order by EPS desc last 24 hours
  • B. select DOMAINNAME (domainqid) as LogSource, sum(eventcount) / ((max(endTime) min(startTime)) / 1000 ) as EPS from events group by domainqid order by FPM desc last 24 hours
  • C. select DOMAINNAME (domainid) as LogSource, sum(events) / ((max(endTime) min(startTime)) / 1000 ) as EPS from events group by domainid order by FPM desc last 24 hours
  • D. select DOMAINNAME (domainid) as LogSource, sum(events) / ((max(endTime) – min(startTime)) / 1000 ) as EPS from events group by domainid order by

Suggested Answer: A 🗳️
You would use single-quotes to define this search string. I believe I had an example in the presentation yesterday I need to fix where I accidently used double- qoutes, which is incorrect.
The AQL search below uses quotes correctly:
select logsourcename(logsourceid) as LogSource, sum(eventcount) / ( ( max(endTime) - min(startTime) ) / 1000 ) as EPS from events WHERE logsourcename(logsourceid) = 'Windows Auth @ 10.10.10.10' group by logsourceid order by EPS desc last 5 MINUTES

Or to snag multiple log sources, for example Windows events, you could use the following: select logsourcename(logsourceid) as LogSource, sum(eventcount) / ( ( max(endTime) - min(startTime) ) / 1000 ) as EPS from events WHERE logsourcename(logsourceid) is ILIKE '%Windows%' group by logsourceid order by EPS desc last 5 MINUTES
