With -Q SECS, fping emits information for the just finished interval. This is good for long-running fping processes where one would like to get an update on recent results, ignoring missing responses from older intervals. This seems appropriate for use with other software like netdata or smokeping.
But for short(er)-running fping processes, e.g., during a change window, it may be more interesting to get a status update since the beginning of the change window, i.e., the start of fping. Adding a comma followed by the keyword "cumulative" to -Q SECS (i.e., -Q SECS,cumulative) changes the interim reports to output the current per system overall statistics, unless -N is used, too.
The new syntax is documented in fping.pod and added to fping -h output.
Four tests are added:
