Devstack has removed the USE_PYTHON3 variable[1][2] and now always uses Python 3. [1] https://review.opendev.org/c/openstack/devstack/+/920658 [2] Commit 5412dbfe7b797149f1f68100de8003b1876398fe Change-Id: I5e7559346781e2ced34671ae2229a3440b7ea163
python-observabilityclient
observabilityclient is an OpenStackClient (OSC) plugin implementation that implements commands for management of Prometheus.
Development
Install your OpenStack environment and patch your openstack
client application using python.
# if using standalone, the following commands come after 'sudo dnf install -y python3-tripleoclient'
su - stack
# clone and install observability client plugin
git clone https://opendev.org/openstack/python-observabilityclient.git
cd python-observabilityclient
sudo python setup.py install --prefix=/usr
Usage
Use openstack metric query somequery
to query for metrics in prometheus.
To use the python api do the following:
from observabilityclient import client
c = client.Client(
'1', keystone_client.get_session(conf),
adapter_options={
'interface': conf.service_credentials.interface,
'region_name': conf.service_credentials.region_name})
c.query.query("somequery")
List of commands
openstack metric list - lists all metrics openstack metric show - shows current values of a metric openstack metric query - queries prometheus and outputs the result openstack metric delete - deletes some metrics openstack metric snapshot - takes a snapshot of the current data openstack metric clean-tombstones - cleans the tsdb tombstones
List of functions provided by the python library
c.query.list - lists all metrics c.query.show - shows current values of a metric c.query.query - queries prometheus and outputs the result c.query.delete - deletes some metrics c.query.snapshot - takes a snapshot of the current data c.query.clean-tombstones - cleans the tsdb tombstones
