Ok the action I wanted to perform was for HA I.e execute a scenario like VM boot and in parallel in a separate process , ssh and restart controller node for instance I thought periodic task would be useful for that. I guess I need to look at some other way of performing this Ajay

Actually that method is not used in Rally yet, except Rally as a Service part that doesn't work yet. As a scenario developer I think you should be able to find everything here: https://github.com/stackforge/rally/tree/master/rally/benchmark So I really don't the case when you need to pass something to periodic task.. It's not that "task" Best regards, Boris Pavlovic On Fri, Nov 21, 2014 at 3:36 AM, Ajay Kalambur (akalambu) <akala...@cisco.com<mailto:akala...@cisco.com>> wrote: Hi I have a question on /rally/openstack/common/periodic_task.py It looks like if I have a method decorated with @periodic_task my method would get scheduled in separate process every N seconds Now let us say we have a scenario and this periodic_task how does it work when concurrency=2 for instance Is the periodic task also scheduled in 2 separate process. I actually want only one periodic task process irrespective of concurrency count in scenario Also as a scenario developer how can I pass arguments into the periodic task Ajay _______________________________________________ OpenStack-dev mailing list OpenStack-dev@lists.openstack.org<mailto:OpenStack-dev@lists.openstack.org> http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
