The _created auto-created metrics (e.g. for Counter) cause failure of promtool check metrics because of lack of HELP #470
Description
prometheus/client_pythonversion:0.7.1- Python version
3.7.1 promtoolversion from currentHEAD:2.13.0-rc.0
When creating a counter, e.g.
c = Counter('some_counter', "Some counter")
this will create two metrics:
# HELP some_counter Some counter
# TYPE some_counter counter
some_counter_total 4.0
# TYPE some_counter_created gauge
some_counter_created 1.5699349744874952e+09
The output lacks the HELP line for the _created metric. This causes a failure with promtool:
$ curl -s http://localhost:8080/metrics | promtool check metrics
some_counter_created no help text
