Log-Level Data Service does not seem responsive

[terry07]

I am trying to pull data from the Log-Level Data Service but neither of the following requests seem to be effective:

r = client.request('siphon', 'GET')
r = client.request('siphon-download', 'GET', data={'siphon_name': 'standard_feed', 'hour' : '2018_09_01_17' , 'timestamp' : '20180901170000', 'member_id' : '311', 'split_part' : '8'})

Any ideas?
Thanks in advance.
