Usage
=======
To use oslo.reports in a project::
Every long running service process should have a call to install a
signal handler which will trigger the guru meditation framework upon
receipt of SIGUSR1/SIGUSR2. This will result in the process dumping a
complete report of its current state to stderr.
import oslo_reports
For RPC listeners, it may also be desirable to install some kind of hook in
the RPC request dispatcher that will save a guru meditation report whenever
the processing of a request results in an uncaught exception. It could save
these reports to a well known directory
(/var/log/openstack/<project>/<service>/) for later analysis by the sysadmin
or automated bug analysis tools.
