[Openstack-operators] ceilometer gnocchi switch in pike release

2018-02-23 Thread Masha Atakova 

Hi everyone,


I’ve been trying to move my openstack setup from ocata to pike release (I know, it’s almost queens!) and I’ve encountered a problem not really described in the upgrade documentation.


Prior to pike, ceilometer telemetry service was storing the telemetry data on it’s own. Starting from pike, there’s another storage component for that, called gnocchi.

I reconfigured the setup accordingly, to use gnocchi as a storage, but the problem is: ceilometer has multiple types of metrics while gnocchi doesn’t have metric types at all.

And it doesn’t really make sense to store metrics of cumulative type (like compute.node.cpu.kernel.time, switch.port.receive.bytes, energy) and of gauge type (like vcpus, volume.size, image.size) in one place.


Have any of you faced this problem? If yes, what are the workarounds that you’ve found sufficient?

I’ve been thinking about different ways to handle this problem, like converting data before it gets written to gnocchi, but I believe there should be a better solution!


Thank you

[Openstack-operators] [nova] [neutron] Hooks for instance actions like creation, deletion

2017-03-16 Thread Masha Atakova 

Hi everyone,

Is there any up-to-date functionality in nova / neutron which allows to 
run some additional code triggered by changes in instance like creating 
or deleting an instance?


I see that nova hooks are deprecated as of Nova 13:

https://github.com/openstack/nova/blob/master/nova/hooks.py#L19

While it's hard to find the reason for this deprecation, I also struggle 
to find if there's any up-to-date alternative to those hooks.


Thanks

experience? What are the problems you've encountered and how critical 
are they?


Thanks in advance for your responses
