|
Multi backend support
|
|
=====================
|
|
|
|
Make OSProfiler more flexible and production ready.
|
|
|
|
Problem description
|
|
===================
|
|
|
|
Currently OSprofiler works only with one backend Ceilometer which actually
|
|
doesn't work well and adds huge overhead. More over often Ceilometer is not
|
|
installed/used at all. To resolve this we should add support for different
|
|
backends like: MongoDB, InfluxDB, ElasticSearch, ...
|
|
|
|
|
|
Proposed change
|
|
===============
|
|
|
|
And new osprofiler.drivers mechanism, each driver will do 2 things:
|
|
send notifications and parse all notification in unified tree structure
|
|
that can be processed by the REST lib.
|
|
|
|
Deprecate osprofiler.notifiers and osprofiler.parsers
|
|
|
|
Change all projects that are using OSprofiler to new model
|
|
|
|
Alternatives
|
|
------------
|
|
|
|
I don't know any good alternative.

Work Items
|
|
----------
|
|
|
|
To add support of multi backends we should change few places in osprofiler
|
|
that are hardcoded on Ceilometer:
|
|
|
|
- CLI command ``show``:
|
|
|
|
I believe we should add extra argument "connection_string" which will allow
|
|
people to specify where is backend. So it will look like:
|
|
<backend_type>://[[user[:password]]@[address][:port][/database]]
|
|
|
|
- Merge osprofiler.notifiers and osprofiler.parsers to osprofiler.drivers
|
|
|
|
Notifiers and Parsers are tightly related. Like for MongoDB notifier you
|
|
should use MongoDB parsers, so there is better solution to keep both
|
|
in the same place.
|
|
|
|
This change should be done with keeping backward compatibility,
|
|
in other words
|
|
we should create separated directory osprofiler.drivers and put first
|
|
Ceilometer and then start working on other backends.
|
|
|
|
These drivers will be chosen based on connection string
|
|
|
|
- Deprecate osprofiler.notifiers and osprofiler.parsers
|
|
|
|
- Switch all projects to new model with connection string
|
|
|
|
|
|
Dependencies
|
|
============
|
|
|
|
- Cinder, Glance, Trove, Heat should be changed
