Thanks for all the pointers. Vahric, we're running into this in our lab on a compute host with 135 instances and 12 meters, 3 of which we developed. /Bill On Tue, Jun 14, 2016 at 2:54 PM, Vahric Muhtaryan <[email protected]> wrote: > Hello Bill > > Possible to share how many instance and how many meter per instance you > collecting and getting this error ? > > I guess for scaling purpose , you are talking about this , right > http://docs.openstack.org/ha-guide/controller-ha-telemetry.html > > Regards > VM > > From: Bill Jones <[email protected]> > Date: Tuesday 14 June 2016 at 18:03 > To: "openstack-oper." <[email protected]> > Subject: [Openstack-operators] Scaling Ceilometer compute agent? > > Has anyone had any experience with scaling ceilometer compute agents? > > We're starting to see messages like this in logs for some of our compute > agents: > >> WARNING ceilometer.openstack.common.loopingcall [-] task <function >> interval_task at 0x2092cf8> run outlasted interval by 293.25 sec >> > This is an indication that the compute agent failed to execute its pipeline > processing within the allotted interval (in our case 10 min).
