Ceilometer

Does the latest version support V2 Web API?

Asked by ericshen

I tried http://localhost:8777/v1/resources and it worked, but http://localhost:8777/v2/resources did not work. So Was V2 Web API supported? or with a different port number?

It is strange, it looks like the return is a webpage.

for me, the return is as follows,

HTTP/1.0 404 Not Found

I used restclient plugin in firefox to send rest request, and then get above response, and I don't why V2 did not work.

I check the Ceilometer Grizzly-3 Milestone at 2013-02-22 and found that V2 was support in this release. I used devstack and enable ceilometer in devstack, and I am wondering how can I check the ceilometer version? Also I want to know why V2 did not work. Thanks a lot for any help :)

pip freeze might give you the ceilometer version. b.t.w. you might want to go to #openstack-metering on freenode IRC for quick debug.

Please check if you removed all the old installation of ceilometer and ceilometer client before you running the devstack.
if still error happened, please paste the log of the ceilometer-api and you localrc without credentials.
And also the irc will be the best place since a lot of nice guys are there to help you out. :-)

My localrc is below:

SERVICE_TOKEN=zhu88jie
SERVICE_PASSWORD=zhu88jie
ADMIN_PASSWORD=zhu88jie
# Enable the ceilometer services

The pip freeze related output of ceilometer
-e git+https://github.com/openstack/ceilometer.git@581344b63993a31eed1af72bb384e42ffe32e292#egg=ceilometer-dev
-e git+https://github.com/openstack/python-ceilometerclient@a550dcfa4971df5ef517aa73d2ebc7a6675c72c6#egg=python_ceilometerclient-dev

Output of of ceilometer-api.log when I try to get v2 api:
2013-03-18 15:43:36.746 10082 DEBUG ceilometer.storage [-] looking for 'mongodb' driver in 'ceilometer.storage' get_engine /opt/stack/ceilometer/ceilometer/storage/__init__.py:57

BTW, I did not install any old version of ceilometer and ceilometer client. I installed devstack and then followed the guide to enable ceilometer in localrc as I attached above, and then re-run stack.sh, then the ceilometer was installed.

From the PiP freeze, It looks like the ceilometer and python-ceilometer are on March 5th, can you try the latest version.

should I uninstall the old version of ceilometer? Can you tell me how to uninstall it? I searched in google and did not found any guide of how to uninstall ceilometer, and sorry for such question as i am new to openstack and ceilometer :).

Same error when I use ceilometer command with version 2.

The simplest way is running ./unstack and then deleting the ceilometer and python-ceilometer directory and running ./stack.sh again.
