Dear all, I have been attempting to use Atlas to launch traceroute measurements recently. Initially, I used ripe.atlas.cousteau to run the measurements in batches, keeping the total number under 10,000 to avoid exceeding the measurement limit. However, only 10% of the measurements returned successful results, while the other 90% showed the status "scheduling denied." Next, I tried launching only 12 measurements in batch, where each measurement contained one traceroute from a specific probe to a designated IPv4 destination. Out of these, 4 succeeded and the other 8 showed the status "specified". Following that, I launched the 12 measurements one by one with 2-second intervals, resulting in a success rate of 6 out of 12. However, when I increased the interval to 3 seconds, the success rate dropped to 4 out of 12. Interestingly, when I created the same measurements for the designated probes and destinations through the web interface, all of them were successful. Below is the Python code I used to launch the measurements: fromripe.atlas.cousteauimport ( Traceroute, AtlasSource, AtlasRequest, AtlasCreateRequest, AtlasResultsRequest, AtlasLatestRequest, ProbeRequest ) traceroute=Traceroute(af=4, target=dstip, description="traceroute subpref ip {} from {}{}".format(dstip, probe_type, probe_value), protocol='ICMP') if probe_type =='asn': probe_value =int(probe_value) source = AtlasSource(type=probe_type, value=probe_value, requested=1, tags={"include": ["system-ipv4-capable"]}) _key = ATLAS_API_KEY_2 for _ inrange(2): atlas_request = AtlasCreateRequest( start_time=datetime.utcnow() + timedelta(random.randint(0, 1)), key=_key, measurements=[traceroute], sources=[source], is_oneoff=True ) (is_success, response) = atlas_request.create() if is_success: print('create_task', dstip, is_success, response) msm_id = response['measurements'][0] return Could you kindly let me know if there might be an issue with my approach or provide any advice on how to improve this process? I would greatly appreciate any guidance. Thank you very much! Best regards, Sun Letong
