Dear all,

I am in trouble with launching a periodical Ping measurement.

my script is like this, but my measurement always fails. I tried several times with different modification on "interval" and "spread".

one failed example can be reviewed here: https://atlas.ripe.net/measurements/15282285/

It works well when I launch a one-off measurement, but every time I try to launch a periodic measurement with the setting above, it fails all the time.

it probably because the "is_oneoff", "interval", "spread" is set wrong, but I can't find a good example for it.

The idea of this test measurement is to start a Ping test every 1 minute, from UTC-now to 5 minutes later. Thus, I'd like to have 5-set result in this measurement.

Could you help me check where I set wrong?

Many thanks,

Yihao
