Usage

Usage

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.

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.

To use oslo.reports in a project, you need to add the following call to setup_autorun() somewhere really early in the startup sequence of the process:

from oslo_reports import guru_meditation_report as gmr

gmr.TextGuruMeditation.setup_autorun(version='13.0.0')

Note that the version parameter is the version of the component itself.

To trigger the report to be generated:

kill -SIGUSR2 <process_id>

Note

On SELinux platforms the report process may fail with an AccessDenied exception. If this happens, temporarily disable SELinux enforcement by running sudo setenforce 0, trigger the report, then turn SELinux back on by running sudo setenforce 1.
