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
