Anyone using cloud based monitoring/logging services with Python logging module?

[Malcolm Greene]

Looking for feedback on anyone who's using a cloud based
monitoring/logging service with Python's standard lib logging module,
eg. services such as Datadog, Loggly, Papertrailapp, Scalyr, LogDNA,
Logz.io, Logentries, Loggr, Logstats?
Would appreciate hearing your experience, pros, cons,
recommendations, etc.
Thanks!
Malcolm
