500 Internal server error

[SubjectXXX]

Followed the instructions, page loads, but spins, console shows

jquery-3.4.1.min.js:2 GET http://195.47.197.49/_monitoring/api/meetings 500 (INTERNAL SERVER ERROR)

Are there any logs available? Any extra ports that needs to be open?

Could be a problem with line: HTTP server will listen on port: 5000 What exactly does that mean?

You are accessing the webpage, so it should not be an issue with any network port. I suspect some API errors in regard to BBB. Can you post the logs returned by the bbb-monitoring container?

sudo docker logs bbb-monitoring

Multiple:

I see. I suspect this is because you are not using the Moodle plugin, which our server had whilst developing the utility. Nonetheless the issue is with the utility. Fix coming shortly.

How would this monitor connect to Moodle plugin?

I tried triggering conf call via greenlight and Moodle plugin, both times I get 500..

[SubjectXXX]

Triggering call from Moodle returns this error I think:

[greenstatic]

It's possible that the real issue is the API communication. Are you sure you entered the API URL and secret correctly? The URL should be like this: https://bbb.example.com/bigbluebutton/api/ - note the api endpoint and trailing slash.

The secret value you should copy from bbb-conf --secret

[SubjectXXX]

I did double check the docker run command and its correct. Using same secret from Moodle plugin and it works there..

Still this error persists:

Where do you pick out server name? From API response or parsed from URL? It is correct in my case..

Also, since error changed from when I triggered call from greenlight to different one when I triggered it from Moodle, API access seems correct?

Also, accessing that bbb api url gives:

SUCCESS 2.0

Tripple checked entered URL and secret, now via api-mate and its correct..

I have created a new branch with the possible fix: https://github.com/greenstatic/bigbluebutton-monitoring/tree/issue-1

I have also created a preview build to see if we have made any progress. Can you pull greenstatic/bigbluebutton-monitoring:version-0.3.1-beta1 and add to the docker run -e "DEBUG=true". This should enable more verbose logging.

The monitor receives "Moodle data" from the BBB API under metadata, specifically a context string which the Moodle plugin passes to BBB when creating the room. Within this string is the name of the corresponding Moodle course which is displayed on the monitor website.

[SubjectXXX]

It works now, altough few problems:

• could you assume, if you do not have metadata with bbb params, that this room was run from server itself, thus simply writing into Origin Server column server name instead of null?
• Creation column is marked Invalid date on both rooms (one from moodle, one directly from BBB server (greenlight UI))
• Origin context is empty in both cases (Moodle and Greenlight entry point)

Bluring out stuff because of internet, not you per se :)

[greenstatic]

I think there are some major differences between your BBB/Moodle setup and ours in which case I made some invalid assumptions.

Since Origin Server to the best of my knowledge isn't dependent on the Moodle plugin I would say there is something weird going on.

After a short discussion with @matjazp, it seems we have a multilingual Moodle installation which makes the Moodle plugin return a XML context - one (course name) for each language. I assumed this is the same for monolingual installations of Moodle but I guess that was another wrong assumption.

Could you enable the DEBUG=true flag when running the docker container and paste the API responses you get from the server? If you have reservations regarding the contents of the response (names, IP's, domains) you can censor them out or email me the response (my email is on my GH profile/website).

No worries regarding the blurring, but I should mention you forgot the blur your IP from your initial issue post :sweat_smile: - not that it's a big deal, it's just an IP which can be found i.e. on Shodan.

[SubjectXXX]

Hehe, that IP is from this reusable testing machine, so no biggie there 🗡

Anyway, sent you email with api call and you can analyze it there.
