When things go wrong in (production) deployments of OpenStack collecting debug
|
|
data is a key first step in the process of triaging & ultimately resolving the
|
|
problem. Projects like Nova has extensively used logging capabilities which
|
|
produce a vast amount of data. This does not, however, enable an admin to
|
|
obtain an accurate view on the current live state of the system. For example,
|
|
what threads are running, what config parameters are in effect, and more.
|
|
|
|
The project oslo.reports hosts a general purpose error report generation
|
|
framework, known as the "guru meditation report"
|
|
(cf http://en.wikipedia.org/wiki/Guru_Meditation) to address the issues
|
|
described above.
|
|
|
|
Models: These classes define structured data for a variety of interesting
|
|
pieces of state. For example, stack traces, threads, config parameters,
|
|
package version info, etc. They are capable of being serialized to XML / JSON
|
|
or a plain text representation
|
|
|
|
Generators: These classes are used to populate the model classes with the
|
|
current runtime state of the system
|
|
|
|
Views: views serialize models into say JSON, text or xml. There is also
|
|
a predefined view that utilizes Jinja templating system.
|
|
|
|
There will be a number of standard models / generators available for all
|
|
OpenStack services
|
|
|
|
StackTraceModel: a base class for any model which includes a stack trace
|
|
ThreadModel: a class for information about a thread
|
|
ExceptionModel: a class for information about a caught exception
|
|
ConfigModel: a class for information about configuration file settings
|
|
PackageModel: a class for information about vendor/product/version/package information
|
|
|
|
Each OpenStack project will have the ability to register further generator
|
|
classes to provide custom project specific data.
