Profiler
|
|
^^^^^^^^
|
|
|
|
The detailed description of the profiler and its config options is available at
|
|
`Profiler docs <https://docs.openstack.org/osprofiler/latest/user/index.html>`_.
|
|
|
|
|
|
Using Profiler
|
|
^^^^^^^^^^^^^^
|
|
|
|
To start profiling Manila code, the following steps have to be taken:
|
|
|
|
#. Add the following lines to the ``/etc/manila/manila.conf`` file (the
|
|
profiling is disabled by default).
|
|
|
|
.. code-block:: console
|
|
|
|
[profiler]
|
|
connection_string = redis://localhost:6379
|
|
hmac_keys = SECRET_KEY
|
|
trace_sqlalchemy = True
|
|
enabled = True
|
|
|
|
Examples of possible values for ``connection_string`` option:
|
|
|
|
* ``messaging://`` - use oslo_messaging driver for sending spans.
|
|
* ``redis://127.0.0.1:6379`` - use redis driver for sending spans.
|
|
* ``mongodb://127.0.0.1:27017`` - use mongodb driver for sending spans.
|
|
* ``elasticsearch://127.0.0.1:9200`` - use elasticsearch driver for sending spans.
|
|
* ``jaeger://127.0.0.1:6831`` - use jaeger tracing as driver for sending spans.
|
|
|
|
#. Restart all manila services and keystone service.
|
|
|
|
#. To verify profiler with manilaclient, run any command with ``--profile <key>.``
|
|
The key (e.g. SECRET_KEY) should be one of the ``hmac_keys`` mentioned in
|
|
manila.conf. To generate correct profiling information across all services
|
|
at least one key needs to be consistent between OpenStack projects.
|
|
|
|
.. code-block:: console
|
|
|
|
$ manila --profile SECRET_KEY create NFS 1 --name Share1 --share-network testNetwork --share-type dhss_true
