Hi Daniel,

I sent an email (included below.) outlining a measurement with a specific interval done through the API and listed the response, please look at the email below. As for the Web UI measurement here is an example:

{u'result': u'/api/v1/measurement/1044471/result/', u'status': {u'id': 4, u'name': u'Stopped'}, u'msm_id': 1044471, u'interval': 1200, u'description': u'', u'participant_count': 50, u'can_visualise': False, u'resolve_on_probe': False, u'start_time': 1386161734, u'af': 6, u'creation_time': 1386161734, u'is_oneoff': False, u'stop_time': 1386165633, u'all_scheduling_requests_fulfilled': True, u'resolved_ips': [u'2001:7b8:40:1:d0e1:0:0:1'], u'dst_asn': u'12859', u'query': {u'type': u'AAAA', u'class': u'IN', u'value': u'nlnetlabs.nl.'}, u'is_public': True, u'type': {u'id': 7, u'name': u'dns'}, u'dst_addr': u'2001:7b8:40:1:d0e1:0:0:1', u'dst_name': u'2001:7b8:40:1:d0e1::1'}

Robert Kisteleki suggested I send it through to atlas@ripe.net which I did and it has been listed as:
[ripe.net #1113749]
I received a response from Robert Kisteleki (which is the very last email included below), he said it might be a week or later until this gets investigated so he was right on the money :-) .

Thank you for your response and we hope to see this bug(or whatever it is) get squashed :D

P.S. If you could, please include Willem Toorop(Willem@nlnetlabs.nl) in the response as he was the one to mention this limitation to me and the one who suggested I email about this. He also sent an email outlining this issue but heard no response so I'm sure he would like to hear when a resolution to this limitation/bug/whatever has been found.

P.P.S. At the bottom of the first included email is our work around which is get the probes specific to our needs (ipv6/4 etc..) and the chunk them into sizable chunks(50 probes work).

Kind regards,
Warwick Louw

Hello,

Regarding the previous email: Measurements at an interval, below is the Json constructed for the measurement:

{'definitions': [{'description': '', 'use_probe_resolver': False, 'af': 6, 'query_argument': 'nlnetlabs.nl', 'query_type': 'AAAA', 'interval': 1200, 'query_class': 'IN', 'type': 'dns', 'is_oneoff': False, 'recursion_desired': False, 'target': '2001:7b8:40:1:d0e1::1'}], 'stop_time': 1386168052, 'probes': [{'requested': 100, 'type': 'area', 'value': 'WW'}]}

And below is the response:

{"error": {"code": 104, "message": "You do not have enough credit to schedule this measurement."}}

It seems as though it's a trivial mistake, that I might actually not have enough credits to perform this measurement but I'm sure I do since it's a simple DNS query with only 100 probes.

With 50 probes:

{'definitions': [{'description': '', 'use_probe_resolver': False, 'af': 6, 'query_argument': 'nlnetlabs.nl', 'query_type': 'AAAA', 'interval': 1200, 'query_class': 'IN', 'type': 'dns', 'is_oneoff': False, 'recursion_desired': False, 'target': '2001:7b8:40:1:d0e1::1'}], 'stop_time': 1386168333, 'probes': [{'requested': 50, 'type': 'area', 'value': 'WW'}]}

This request is executed as expected. With the following response:
{u'measurements': [...]} (measurement id removed.)

To get past this problem we have been chunking our probes in groups of 50. I just thought you might be interested.

Kind regards,
Warwick Louw

Hi,

Got it, we'll look into this (probably early next week when the best person for this is back).

Regards,
Robert
