i'm not sure what rabbitmq has to do with gnocchi since gnocchi itself 
does not utilise rabbitmq? you mean ceilometer? here? which queues are 
growing in rabbitmq?

what is your error? gnocchi:// is just an alias for direct:// publisher 
so it won't change much.

is it safe? i'm not sure if backporting newer ceilometer code will work 
with gnocchiv2.1. that said, i don't recommend you use gnocchiv2.1 as i 
would say only starting in gnocchiv3 is it actually usable (my personal 
opinion). if you backport newer dispatcher but use gnocchiv3+ or 
gnocchiv4, it should work but you should probably understand the code 
before doing so.

backlog in gnocchi? if you mean when you run 'gnocchi status', the 
values never stop growing, then i would say 1) only gnocchiv3+ is usable 
2) add more metricd workers 3) gnocchiv4 is better than gnocchiv3.

Re: [Openstack-operators] Ocata instance snapshot

[Saverio Proto]

Hello Ignazio,

do you mean the instance has booted from volume ?

when is booted from volume this 0 bytes glance image is created
together with a cinder snapshot.

I wrote about it for my openstack users here:
https://help.switch.ch/engines/documentation/backup-with-snapshots/

I think that is by design. Also my opinion is that the current design
with booting from volumes or images and different snapshotting paths
is very confusing for the users. That is why I had to write that page.

Re: [Openstack-operators] [dev] [doc] Operations Guide future

[Alexandra Settle]

Hey Blair,

Thanks ( I appreciate your offer of assistance. We are in full swing at the 
moment. The spec is very close to being merged. You can view that here: 
https://review.openstack.org/#/c/472275/ 

I am still looking for someone who can help us out with the pandoc conversion. 
I am happy to go through it with said individual.

Cheers,

Alex

I can't realistically offer much time on this but I would be happy to
help (ad-hoc) review/catalog/clean-up issues with export.

Agreed, need to maintain discoverability.

[Openstack-operators] Ocata instance snapshot

[Ignazio Cassano]

Hi All,
using ocata dashboard I am trying to create instance snapshots.
If the instance has an attached volume, the image created is empty.
If the instance does not have an attached volume, the image created is not
empty.
This is by design or I must change my configuration ?

Regards
Ignazio
