Hi,
It seems that you do not have extended-utm-log enabled on the foritgate under the webfilter profile.
You can also to genereate the results from the Traffic log like this:
SELECT $flex_timescale AS hodex,
COUNT(*) AS totalnum
FROM $log-traffic
WHERE $filter
AND `catdesc`=' Job Search'
AND `action` IN (' accept' ,' close' )
AND `utmevent` IN (' webfilter' , ' banned-word' , ' web-content' , ' script-filter' , ' command-block' , ' script-filter' )
AND `utmaction`=' passthrough'
GROUP BY hodex
ORDER BY hodex ASC
After then you create a Table Chart - not Line chart as the following - set the Display mode to LINE:
Have a fun! :)
