Open Stack

How did you install Gnocchi?

 

It’s not part of OpenStack anymore. In local.conf:

 

enable_plugin gnocchi https://github.com/gnocchixyz/gnocchi.git

CEILOMETER_BACKEND=gnocchi

GNOCCHI_DEPLOY=uwsgi

 

The DEPLOY option is not mandatory, but it has the advantage that all of Gnocchi’s logging can be viewed with journalctl.

If you did that, what happens when you launch the Gnocchi services?

 

In addition to that, I had to manually populate the database with Ceilometer’s resource types:

 

ceilometer-upgrade --noskip-gnocchi-resource-types

 

 

 

The documentation is a bit lacking. Ceilometer produces samples and publishes them through the Gnocchi publisher driver (/opt/stack/ceilometer/ceilometer/publisher/gnocchi.py). When a sample arrives for a resource that doesn’t exist in the Gnocchi data store yet, the publisher creates it first, then adds the sample. If you don’t have the resource types in Gnocchi, this fails and you have no data at all.

 

I’d like to know how you make progress (private communication OK). I managed to set everything up, but the samples come in with a huge delay, with the effect that my alarms have insufficient data. This is on a master clone of DevStack. Perhaps you can help me figure out what’s wrong!

 

Bernd.

Subject: [Openstack] [Ceilometer] Unable to retrieve data from ceilometer

 

Hi Everyone, 

 

Problem: Not able to get data from Ceilometer. 

 

Description:

 

Installed Openstack using Devstack. 

 

Enabled ceilometer plugin and enables services such as ceilometer-agent-notification, ceilometer-agent-central and ceilometer-api. The services are running along with the default openstack service that comes with devstack. 

 

Configured (/etc/ceilometer/) pipeline.yaml with: 

- notifier://

- gnocchi://

for all the meters in the file. 

 

I haven't tried the publishing method http:// as I am fairly new to it. 

 

With pike, I have read that the command "ceilometer" is deprecated and we have to use gnocchi. 

 

Tried using gnocchi but unable to get the gnocchi.meterd.service and gnocchi.statd.service started. 

 

Please help me with any documentation that would provide some material to move further with my attempt to install and run ceilometer, gnocchi and get the data from them. 

 

It would really helpful to know how and where the metering samples are built and can I access them?

Thanks and Regards
Gautham
