Thanks. Still no luck.
I am running this on a linux machine.
$ python tutorial_server_data.py
Create database: tutorial
Create a retention policy
Write points #: 4320
ResultSet({})
Result: ResultSet({})
myclient2 = InfluxDBClient(host, port, user, password, 'tutorial')
query = 'SHOW MEASUREMENTS'
result = myclient2.query(query)
result
ResultSet({'(u'measurements', None)': [{u'name': u'server_data.cpu_idle'}]})
