Troubleshooting

This section contains information on troubleshooting, common gotchas, and generally things to watch out for.

Testing the Service

A good practice is to hit the :ref:`opendcre-test-command` endpoint after starting up a service. It can also be useful in ensuring that a service is still running. It will only return "ok" if the service is up and running, but note that an "ok" response from the test endpoint does not indicate the lack of errors elsewhere - it only means that the Flask application within the Docker container is running and that it is reachable.

Raising an Issue

If you come across an error or issue with OpenDCRE or just have a question/suggestion about it, please raise an issue for it!

If raising an issue around an error, please include as much context information around it as possible.

Gotchas

scan results unavailable on init

Particularly in cases when there are many devices configured, or where there is high network latency when configuring LAN Devices, one may observe that the initial startup takes some time and scan results are not available. OpenDCRE attempts to enumerate remote devices (e.g. BMCs for IPMI) on init by default, so that it can cache the results for subsequent commands. As such, the initialization process may take a few minutes.

To help mitigate this, some configuration options have been added around LAN-based devices, both for multi-threaded device initialization, and deferring scan to a time post-initialization.

If can results are unavailable for an extended amount of time, or just to validate that there are no errors while the initial scan takes place, one can examine the OpenDCRE log file, as described in the :ref:`opendcre-debugging` section.
