Skyline v1.0.0-beta - the crucible branch¶
The crucible branch had an issue open called Bug #982: Too much in crucible branch
Too much in crucible branch
I have added some pep20, sphinx docs and python package restructuring from @languitar etsy/skyline #93 - https://github.com/languitar/skyline/tree/setuptools - which turns skyline into a python package
The reality was that it was too difficult to reverse engineer all the changes into separate branches, so it continued unabated...
This version of Skyline sees enough changes to worthy of a major version change. That said the changes are/should be backwards compatible with older versions, mostly (best efforts applied) with a caveat on the skyline graphite metrics namespace and running Skyline under python virtualenv.
Conceptual changes¶
The FULL_DURATION
concept is a variable and it is a variable in more ways than
the settings.py context. Conceptually now FULL_DURATION
, full_duration
,
full_duration_seconds
and full_duration_in_hours
are variables in different
contexts. The FULL_DURATION
concept was important in the Analyzer context,
but the concept of the full duration of a timeseries has become somewhat more
variably and is different within different scopes or apps within Skyline. It is
no longer really a single static variable, it is handled quite dynamically in a
number of contexts now.
Etsy to time()
¶
This whats new will cover all the new things that the crucible branch introduces since the last Etsy commit on master of etsy/skyline, although not strictly accrurate, for the purposes of generality it shall be assumed that no one is running the new Skyline features that have not been merged to the Etsy Skyline.
anomaly_breakdown metrics¶
sphinx documentation¶
Performance tuning¶
Process management¶
A number of the apps have had better process management handling added and the
parent process now spawns processes and terminates then if they have not
completed in MAX_ANALYZER_PROCESS_RUNTIME
, ROOMBA_TIMEOUT
and other apps
have this specified too, either using the MAX_ANALYZER_PROCESS_RUNTIME
as a
hardcoded one where appropriate. This handles a very limited number of edge
cases where something that is host machine related causes the Python process to
hang.
Analyzer optimisations¶
algorithm_breakdown metrics¶
Webapp¶
Some simple and basic security was added to the Webapp now it can be enabled to access a MySQL database in the Panorama context.
- Only allow IP addresses in
WEBAPP_ALLOWED_IPS
- There is now a single HTTP auth user
WEBAPP_AUTH_USER
andWEBAPP_AUTH_USER_PASSWORD
- The Webapp can now be served via gunicorn and Apache (or any other HTTP reverse proxy).
