[monasca][kolla-ansible] Help for a monasca newbie to get metrics for instances needed
Hi!
I'm trying to explore monasca, but I'm bit lost in how to get metrics from a project/tenant collected. I'm using kolla-ansible in my test setup running ubuntu-source images. Ubuntu release is Yoga.
Monasca seems to be up and running. I can see the default metrics with a appropriate user in the monasca_control_plane project.
cpu.* disk.* io.* load.* mem.* monasca.* net.* ntp.*
And I find measurements in the influxdb, but only metrics/measurements for the openstack hypervisor nodes yet. What I'm missing after searching the existing documentation is how I can enable a plugin as for libvirt for example or whatever the recommendation for monitoring the instances is.
As I have found the plugins directory on the hypervisors under /etc/kolla/monasca-agent-collector/plugins I thought putting a config file like in the documentation [1] for the libvirt plugin and restart the monasca-agent-collector would be sufficient. But all I got was an error message:
2022-09-11 12:22:26,412 | ERROR | collector | monasca_agent.common.util(util.py:529) | Unable to import check module libvirt.py from checks_d Traceback (most recent call last): File "/var/lib/kolla/venv/lib/python3.8/site-packages/monasca_agent/common/util.py", line 520, in load_check_directory check_module = load_module('checksd_%s' % check_name, check) File "/var/lib/kolla/venv/lib/python3.8/site-packages/monasca_agent/common/util.py", line 470, in load_module module_spec.loader.exec_module(module) File "<frozen importlib._bootstrap_external>", line 848, in exec_module File "<frozen importlib._bootstrap>", line 219, in _call_with_frames_removed File "/var/lib/kolla/venv/lib/python3.8/site-packages/monasca_agent/common/../collector/checks_d/libvirt.py", line 20, in <module> import libvirt ModuleNotFoundError: No module named 'libvirt'
As it seems the plugin system dependencies like libvirt-dev are missing. So I assume I have to rebuild the container myself and/or open an issue on opendev.org.
Or is there another way to get metrics for instances?
Next question: even if I had a running libvirt plugin. What has to be done to enable another user in a normal tenant project to use these metrics? Just add the monasca-read-only-user to user(s) which shall be enabled to manage alarm definitions, alarms and notifications? Will the tenant then see or at least use the metrics for his (and only his) project?
I found a lot of high level documentation, (base) installation instructions, hints for developers on how to extend monasca, but nothing beyond the initial setup for monasca newbies like me. I queried the all-knowing, all-seeing trash heap, mailing lists, and the YT academy already. May be I just missed something. So hints are welcome!
BTW. Is the kolla-ansible part of monasca still in active maintenance and development? I stumpled upon the same error as in [2] and I'm getting an HTTP 500 error when trying to open the monitoring overview and is still unassigned.
Thanks in advance!
Kind regards,
Christian Stelter

I have little to no knowledge of the innerworkings of Monasca but I can answer this question as one of the maintainers of Kolla and Kolla Ansible. There is currently no member of the team working on the Monasca integration and the situation is caused by the low maintenance of the upstream, i.e. Monasca itself. We are open to collaboration on fixing the situation but we don't have the bandwidth to do it ourselves.

Thanks for your feedback on the maintenance part! So I will try then to dig into it further myself.
May be someone else can answer the rest. Ceilometer seems to be more popular. But I'm still curious on get monasca running. ;-)
Best regards,
Christian
