Seems like the first issue with making this useful with RHOS 3.0 is getting the output. The simplest solution would be to pipe the stderr of our daemons to a hardcoded file. Other more robust solution would be to patch guru meditation code to accept a file to send it's report to. I've posted a patch upstream (see https://review.openstack.org/#/c/84168/) to fix the output issue. I've already tested it with RHOS3.0 packages and it seem to do be working. Once we do a build with this patch, sending SIGUSR1 to a service will result in it dumping the GuruMeditation report to a file called $service_name_gurumeditation_$timestamp where timestamp is the time the report was requested. QE team: Veryfiying this can be done as follows: 1) Send all nova processes SIGUSR1 2) Make sure each one of them creates a /var/log/nova/$SERV_NAME_gurumeditation_$(date +"%Y%m%d%H%M%S") and that the file contains details about running processes threads, configuration etc. In accordance with the Red Hat Enterprise Linux OpenStack Platform Support Policy, the one-year life cycle of Production Support for version 3 will end on July 31, 2014. On August 1, 2014, Red Hat Enterprise Linux OpenStack Platform version 3 will enter an inactive state and will no longer receive updated packages, including Critical-impact security patches or urgent-priority bug fixes. In addition, technical support through Red Hat's Global Support Services will no longer be provided after this date. We encourage customers to plan their migration from Red Hat Enterprise Linux OpenStack Platform 3.0 to a supported version of Red Hat Enterprise Linux OpenStack Platform. To upgrade to Red Hat Enterprise Linux OpenStack Platform version 4, see Chapter "Upgrading" in the Release Notes document linked to in the References section.
