Hi,
Depending of the Ceph version you can have the files in different places,
but in any case is easy to search the file "module.py" in any of your
manager hosts, the results will show you the location of the manager
plugins.
In Nautilus they are in "/usr/share/ceph/mgr/"
You can see the active manager using the command "ceph -s"
A good source of information to see what is happening is the manager log
file (in var/log/ceph) in the manager host,
You can change the log level to debug using:
ceph daemon <your-mgr> config set debug_mgr 20/5
restore the log level:
ceph daemon <your-mgr> config set debug_mgr 1/5

Hi,
I did the steps as suggested in the documentation, but the plugin still
can not run.
I have tried to get the mgr module path but there is no configuration
option for that. Do you know how can I know what is the path?
And is there any command to get details on the active manager? Just to
make sure it is running on my host.
Thanks,

Hi Rima,
- Review documentation:
https://docs.ceph.com/docs/master/mgr/modules/#creating-a-module
- Take a look at one example, in this folder you can find several of them:
https://github.com/jmolmo/ceph/tree/master/src/pybind/mgr
Hello: is the most simple manager module
ssh: the most updated
And ... be sure that your manager module files are located in the same
host where the active manager is running.

Hi there,
I have been trying to add a new plugin to the ceph mgr but can't seem to
figure out why it is not working.
I have created a directory under /ceph/mgr/ and added the module.py file
there. Afterwards I added the plugin's name to the file
/usr/share/ceph-ansible/roles/ceph-mgr/defaults/main.yml under
ceph_mgr_modules field. But when I run "ceph mgr module enable
<plugin-name>" I get this error: Error ENOENT: module 'newplugin'
reports
that it cannot run on the active manager daemon: (pass --force to force
enablement).
Did anyone try this before and can share some insights.
This matter is urgent to me so I would really appreciate any help I can
get.
Thank you

I had a lot of trouble getting plugins to work, since they needed
py-libs that I did not (yet) have.
Python tracebacks are logged in the ceph-mgr log file.
And there is was usually quite fast clear what the problem was.
Big chance that ceph-mgr is not loading you plugin due to loading errors
but the traceback in the log should give you more info.

New subject: New Ceph Plugin - assistance
Thank you! The logs did help but I had to add log_to_file (as true) in the ceph.conf in
order to see it.
The plugin was successfully installed and did run as expected and could produce output as
desired and implemented in the code. However, I tried to write a new function, but
unfortunately it produced an error, but when I restored the working code I could not
enable the plugin again. Now it says: " Error ENOENT: all mgr daemons do not support
module 'newplugin', pass --force to force enablement".
I tried restarting the ceph-mgr, and made sure to do all the steps I did before, but seems
that it's still stuck on this error.
Do you have any ideas of what might help? Could this be a bug in ceph?
BTW I am using nautilus
