Dear list,

I encountered some cases where the actual time interval between two neighbouring measurements being much larger than the scheduled value.

Have you witnessed similar cases? I appreciate explanations on underlying reasons.

Here goes an example:

from ripe.atlas.cousteau import AtlasResultsRequest

filters = dict(msm_id=1010, probe_ids=[16981], start=1470055258, stop=1470056217)

is_success, results = AtlasResultsRequest(**filters).create()

if is_success:

for mes in results:

print mes.get('timestamp', -1)

The above code requests some built-in ping measurements (240s interval) made by probe 16981 and prints their timestamps. See below for the execution result:

Four measurements are retrieved within the given time range. I noticed that time interval between the 2nd and the 3rd measurement is 479s much larger than the planned value 240s.

How come?

Many thanks for your attention.

Best regards,

wenqin
