Hi, for some reason the "scalelight-api"-Container didn't automatically check whether the DB was available and primed - at least in my case.
I needed to do a
./bin/rake db:reset
to create it - that wasn't in the documentation...

I shared the PostgreSQL-Server with greenlight - it uses docker-compose to automatically pull a postgres v9.5 container. So my DATABASE_URL is:

DATABASE_URL=postgresql://postgres:<here_goes_my_password>@db:5432

and "db" is the Service name in a Docker-Compose.yml file for Scalelite and greenlight on one host...

Hi!
im stuck at starting the scalelite API

Hi guys,

Sorry for the silly question.
I have deployed Scalelite, connected 3 bbb servers to it. But I can't understand how to connect moodle and scalelite.

Thank you for any advice!

I'm not completely sure that a mistake in my NFS setup can lead to the problem, but following the steps in the documentation, the BBB server got "permission denied" when executing rsync against NFS mount in scalelite_post_publish.rb.
After some checks i found that scalelite_post_publish.rb should be executed with scalelite-spool as PRIMARY group, or the directory/file creation fails.
I hacked scalelite_post_publish.rb to do this by using the linux command "sg" which execute a command with the primary group changed and the publish copy to scalelite works.

The following are the relevant changed/added lines.

  extra_rsync_string = extra_rsync_opts.join(' ') 
  puts("Adding extra rsync options:  #{extra_rsync_string} ")

  puts("Transferring recording archive to #{spool_dir}")
  system('sg','scalelite-spool', '-c', "rsync --verbose --protect-args #{extra_rsync_string} #{archive_file} #{spool_dir}") \
    || raise('Failed to transfer recording archive')

With some recordings (not all of them) i'm getting this error:

E, [2020-03-24T23:39:20.807958 #6] ERROR -- : Failed to import recording: undefined method `update!' for nil:NilClass
W, [2020-03-24T23:39:20.808126 #6]  WARN -- : /srv/scalelite/lib/recording_importer.rb:31:in `block (2 levels) in import': undefined method `update!' for nil:NilClass (NoMethodError)

i would like to understand why, but i'm concerning where is defined the update! method ?
I can't find it in the code: it's a bug ?

Thanks a lot for your efforts, i'm going addicted with scalelite, but i'm not a ruby developer.

Hi,

Everything works perfect exept recordings :)

I setup 3 bbb server and try to use cifs..
Recordings stay in raw folder in bbb. How can I debug it for finding wrong config..

Thanks in Advance

any help with this?

Hi, when starting to setup scalelite, I thought that it would have been nice to have a tarball of the systemd service files so I wouldn't need to copy&paste them to my system...

I finally went with docker-compose, so I didn't need the files you provided, but maybe someone else would like that, too.

When I mount NFS with this:

mount private_network_ip:/data/recordings /mnt/

Or if I add this to my fstab:

private_network_ip:/data/recordings    /mnt/    nfs    defaults        0 0

When I do:

I get

For example, if you have two servers and there are three meetings running:

server1:    1 Meeting, 50 active users
server2:    2 Meetings, 5 active users

When now a fourth meeting wants to start, it will be on server1, but it would be better on server2, or did I misunderstand something?
Because the server-load is the number of meetings on a server, as seen here: https://github.com/blindsidenetworks/scalelite/blob/master/lib/tasks/poll.rake#L36

and here (only incremented on meeting create):

Hello All,

I had been used Sakai (12.5) with single BigBlueButton in our University for a long time.

After Scalelite v1.0 released, I changed my env single BBB server to scalelite with 9 BBB servers.

Scalelite and BBB servers running successfully. There are no error.

After I changed my env, I edited in sakai.properties

from
bbb.url=https://single-bigbluebutton.xxxxxx.edu.tr/bigbluebutton/
bbb.salt=****

to
bbb.url=https://scalelite.xxxxx.edu.tr/bigbluebutton/
bbb.salt=****

Today, I realized that in some of the courses offered in Sakai, students can access the records on all servers. And any lecturer can delete these records. In fact, instructor only needs to view the records in his/her course.

This occurred only in 39 of the 1880 lessons opened on Sakai.

Is this problem related to Scalellite or Sakai's BBB tool?

Do you have any suggestions?
Thanks in advance.

Hello,

I implemented a BBB cluster, all works fine, but when I'm in a room, if I create a Breakout room, the system redirect the users to the ending page, as something goes wrong.
Are there any parameters to enable or any api value to set to enable this function also using the cluster?

Hello guys,
I'm bit confused.
Regarding this step https://github.com/blindsidenetworks/scalelite#configure-your-front-end-to-use-scalelite, the BBB server URL must be set to http(s)://<scalelite-hostname>/bigbluebutton/.
I.e., we have bbb-1.example.com and scalelite.example.com. Must I execute bbb-conf --setip scalelite.example.com on the BBB server to make it work? After this command, I got an error on BBB server.
Definitely I'm doing something wrong.
Thank you for any help!

We have setup Greenlight frontend pointing to our Scalelite load balancer. Load balancing is working fine and we are able to create sessions on particular servers under LB. However there is an interesting issue. We have 3 servers under LB as per:

$ docker exec -it scalelite-api bin/rake servers
id: e2de6ff5-6955-48ab-9223-3521ced972cc
url: https:///bigbluebutton/api
secret: secret1
enabled
load: unavailable
offline
id: 5a85d300-85be-4f63-9abf-244e6efe18e2
url: https:///bigbluebutton/api
secret: secret2
enabled
load: 0.0
online
id: 56bd3e1e-5051-4d52-b532-53faa2515bd1
url: https:///bigbluebutton/api
secret: secret3
enabled
load: 0.0
online

So as per above server1 is down, server2, server3 are up. With such greenlight while clicking Meeting Rooms we are getting: Invalid BigBlueButton Endpoint and Secret.

in LB logs I can see:

I, [2020-03-22T11:06:22.285650 #6] INFO -- : [b274ee57-e874-429e-841e-01339e566c9c] Started GET "/bigbluebutton/api/getMeetings?checksum=f6a8f514c05306ae634616879116f3245d459dbb" for <LB_IP> at 2020-03-22 11:06:22 +0000

It looks like scalelite is trying to get server meetings from offline server. The same error is when server1 is disabled.

Error is gone when we remove server from LB.

I find it as an issue as LB is reporting online/offline status so should probably not to try getting meeting rooms from offline servers

Hello,

we have a little problem an looking for a solution. At the moment we had 5 BBB server behind scalelite
bbb1 - bbb5. bbb1 - bbb3 are older real hardware devices with 12 cores (not so fast) and bbb4 and bbb5 are very fast virtual devices (8 cores). They are added to scalelite in order of their names.

Now some of our teachers produces recordings in the evening, that results in bbb1 had a lot of ffmpeg jobs and not finshed in the morning. Over night bbb1 had an average load of 15% so not all cores do rendering.

Now my question: Is the a way to change which bbb servers are served first (maybe the order the added?). Or can we change this in another way.

best regards
Sebastian

I had a lot of records, now they are all gone, after changinf the .env route to use scalelite

Hello,

First of all, thank you so much for this great solution specially with the current situation as it is so much in needs.

We have implemented the solution just today and everything worked perfectly and the high load is getting distributed.

One small issue we are facing, as we are using BBB with Moodle, we are not able to find the recording links once it process and published in Moodle, however we can see them on the server.

Could you please help us on this.

Many thanks again.

Best wishes,

Hello,

I've made some tests. I've changed url of redis HOST (127.0.0.1 instead of an external ip) in file /etc/default/scalelite.
I've restarted and it has worked
But if i come back to previous URL with external IP, and restart every, it seems not to use the nex configuration.
example : When i run servers, it show me the error :
Redis::CannotConnectError: Error connecting to Redis on 127.0.0.1:6379 (Errno::ECONNREFUSED)
but bu my conf specify another ip.
I've tried to clean docker images. It may have some cache somewhere...
thanks

Problem:
When you delete a recording from the greenlight (connected to scalelite) webgui, the files are not deleted from the disk on the scalelite server.

Solution:
mount $SCALELITE_RECORDING_DIR in systemd scalelite-api.service

ExecStart=/usr/bin/docker run --name scalelite-api --env-file /etc/default/scalelite --network scalelite --mount type=bind,source=${SCALELITE_RECORDING_DIR},target=/var/bigbluebutton blindsidenetwks/scalelite:${SCALELITE_TAG}-api

In the main README.md in section Configuration -> Environment Variables -> Required there is a little typo in the sample command for SECRET_KEY_BASE:
openssl ran -hex 64 should be openssl rand -hex 64

Hello,

One more issue we are facing is, the scalelite server is loosing it connection with BBB servers between time to time

and then we go back and add them all manually.

Could you please help us on why this is happening and what do we need to check and change?

Thank you so much, it is much appreciated!

Best Wishes,

Using a Moodle instance connected to my Scalelite with 3 servers, we hit this problem:

• the teacher enter into the room from moodle and scalelite point to bbb1
• some students enter the room and are redirected to bbb1
• the teacher got a problem on their firefox, so exit the room and reenter and scalelite point it to bbb3
• all subsequent students goes to bbb3, but the first one remains obviously on bbb1

so the room is splitted onto two servers: is this a right behaviour or i'm missing anything ?

Hi,

Where is our mistake?

Hi all,
I've installed scalelite and 5 bbb servers, connected on the scalelite.. it seems working fine..
I can see rake servers / rake status all perfect..
But I'd like to use scalelite under moodle but it's not satisfied..

First, is it needed to work bbb on scalelite itself? If I write scalelite bbb api/secret on the moodle it si only work on bbb not on load balancer.. If I stop bbb on scalelite, moodle doesn't connect and says server is not reaching... If I use one of my bbb servers, moodle work only with that one and scalelite shows me on that server have some users/meeting on that one only..
So, I can not find a way to load balancing with moodle...

Is there anyone tell me please:

• scalelite need a bbb on same server itself first?
• in moodle, which api address and secret needed? and how can i obtain it for use with scalelite?

any help will be very appreciated..
Thanks..

Hi ,
I want ask something. Can i install scalelite server and postgresql in same server?
If is it true i got an error message.
What is correct DATABASE_URL for env. ?
Here is errors screenshots

In the end_meeting function, the meeting is only removed from the database if the end_meeting call that is send to the BigBlueButton server succeeds.

It should always remove the meeting from the database, regardless of what happends with the end_meeting call

Hello,

Is it possible to set the weight for each server in the pool, for now, Scalelite determine the current server load by the number of connected users then send the request to the least loaded server in the pool, what if I have one server can handle more requests than the others?

Thanks and appreciate your feedback.

Steps I made:
1- Installed Scalelite, Redis, Docker and BBB on a server named "BBBM" for example.
2- Installed BBB on 3 other servers "BBB1, BBB2 and BBB3" for example.
3- Added the 3 servers to the pool and checked them they are all enabled and online.
4- I logged to Moodle and went to BBB plugin and added the link to the main server bbbm.example.com/bigbluebutton and the load balancer secret in "Shared Secret" field.
5- When I try to open any classroom or create I get this error "bigbluebuttonbn/You did not pass the checksum security check".

What I Checked:
1- BBB is working on main server.
2- Checked Scalelite, Docker and Redis ,,etc.
3- Tested connection with the BBB secret on the main server it's working.

Any help?

getMeetings and rake status will crash in case when any of BBB servers (even disabled) do not respond (e.g. offline/maintenace)

Hello,
The scheme on documentation shows a different dns name for each bbb instance. Does it implies to have a public ip for each one ? Or can I use haproxy and clever UDP port forwarding to use a single public ip for all the setup ?
Thanks.

BigBlueButtonBN:
bigbluebuttonbn/You did not pass the checksum security check

demo1.jsp:
Error: getJoinURL() failed
checksumError: You did not pass the checksum security check

Does anyone have idea how to debug this?

Rake shows that connectivity to our bigbluebutton is successful, meaning secrets are correct.

~ $ ./bin/rake status HOSTNAME STATE STATUS MEETINGS USERS LARGEST MEETING VIDEOS bbb01.aih.nsw.edu.au enabled online 0 0 0 0
I have generated SECRET_KEY_BASE as per instructions in /etc/default/scalelite and copied it to Moodle. I pointed scalelite URL to Moodle plugin and Shared Secret copied from the SECRET_KEY_BASE.

hello,

When i try to create a metting on my scalelie, i've got this message :
Could not find any available servers.
This is returned by the API.

When i look my servers, all is allright, the command bin/rake status returns :
Running via Spring preloader in process 8561
HOSTNAME STATE STATUS MEETINGS USERS LARGEST MEETING VIDEOS
server1 enabled online 0 0 0 0
server2 enabled online 0 0 0 0

What can i can check ?

Hello,

finally we are finshed setting up scalelite. Is it possible to uses 2 clients (moodle and greenlight) in front of scalellite. I think the only problem would be, that the meetingid could be the same ore are they unique?

Best regards
sebastian

I get the error below for the scalelite-nginx.service:

Apr 01 20:27:39 sc.aabbccddee.ke docker[7820]: 2020/04/01 17:27:39 [emerg] 7#7: could not build server_names_hash, you should increase server_names_hash_bucket_size: 32
Apr 01 20:27:39 sc.aabbccddee.ke docker[7820]: nginx: [emerg] could not build server_names_hash, you should increase server_names_hash_bucket_size: 32

The actual length of my domain name is sc.aabbccddee.ke (16char). I know I can edit the image (do you recommend?) and fix this in nginx.conf by adjusting the bucket size upwards.

Can you consider raising this value in the container so that it works for slightly longer domain names without having to edit the image manually? For now I have it working using a short domain name but I would like it work with the longer domain name since it is the one reserved for the project.

Hello All,

We are trying setup Moodle with Scalelite. When a user tries to join the session the error "You did not pass the checksum security check" is displayed. I reviewed all the documentation and couldn't find the problem.

If I point the Moodle directly to the BBB server everything works.

As it's just a test, the environment is all http

What am I doing wrong?

Thanks!

is there anyway to remove these warnings?

I'm running a scalelite instance behind an ELB which has the SSL cert. The thumbnail URLs are coming through as HTTP rather than HTTPS causing my site to be marked as insecure.

The Docs just say I need to set up redis, but nothing more...

Good morning.

Sorry to write here, but I don't have very clear where to post doubts.
What I wanted to know is: Is it possible to have the scalalite server connected to a farm of servers with a VPN, and that the only server with a public IP and Public access could be the scalalite server? Or on the contrary, Scalalite server redirects BBB api clients to the available server and all the BBB servers in the farm need to have public access?

Sorry for the silly question, but it is very important for us to know this aspect. Thank you very much and this project is really awesome!!

I think the documentation its too much for someone that comes from just installing bigbluebutton, please, can anyone provide detailed steps to install scalelite, thank you so much .

Also its possible to install it into a VirtualBox server to test?
I have 2 bigbluebutton instalation and I really want to improve the management with scalelite, any help out there?

Thanks a lot

I cant find any mention of Canvas
Can I balance BBB servers and Canvas with this project? how ?

I'd expect http sessions redirected to https on an SSL-enabled web server.

My suggestion is to just change the HTTP server block in /etc/nginx/conf.d/scalelite-ssl.template to redirect clients to the SSL server...

If you think the server should also be available on HTTP, please at least make it configurable for those of us that think otherwise.

Hello,

we had a long time only one bbb server, last friday we finished setting up scalelite. We transfered local redings via script but this doesn't work for every recording. So some recordings are still missing, so I started the tranfer again. Now I see a list of recordings in the spool folder the missing ones too, but it seems that they aren't procced.
The Importer tast is up.

Any Ideas.

This is less a bug/issue than more a general question:

is there any solution for the 'phone number conference join' using scalelite? At the moment the caller needs to know which instance he has to call to join a conference.

A centralized phone number would be much easier for people w/o internet access, but requires the knowledge which extension to forward based on the load balancer.
