Removing external parenthesis (not necessary). Co-authored-by: Alex Demidoff <a@demidoff.me>
Removed the bool evaluation for threshold; it was not the intention for the threshold to be converted to 0 or 1, and that was preventing the alert from being auto-silenced when seconds_behind_source went below the threshold value.
