Lecture Capture Agent Real Time Dashboard

Peakaboo

Moved to https://gitlab.developers.cam.ac.uk/uis/devops/lecture-capture/peakaboo

A real time dashboard for the remote monitoring of Opencast compatible capture agents

To run in development

mkdir config
cp docs/settings.example.json config/settings.json
chmod u+x run
./run

The meteor applcation will build then point a web browser at:

http://localhost:3000

optional: if you get errors at runtime, try installing the node packages:

meteor npm install

To run in in production

Peakaboo has been dockerized so its super straight forward to get this running in a production environment. There are however alternatives to running meteor apps in production but they aren't covered here.

Its highly recomended you run this as a non-root user. Create a new user, a good name would be peakaboo

First generate a valid SSL certificate. You can generate a self signed certificate or you could also use Letsencrypt with certbot https://letsencrypt.org/.

You will also need to create a new .htpasswd file to allow clients to POST images back to peakaboo

move into the docker folder and place your SSL key file and certificate into the Nginx

cd .docker/
cp /path/to/ssl-key.file nginx/my.key
cp /path/to/ssl-cert.file nginx/my.crt
cp /path/to/.htpasswd nginx/.htpasswd

Install docker and docker-compose. Please refer to the latest docker documenation on how to get started on your platform https://docs.docker.com/engine/installation/ https://docs.docker.com/compose/ you can also install the latest docker-compose via pip

pip install docker-compose

In production Meteor apps get their settings from enviroment variables, these can be set in the .bash_profile or exported on the fly. Export your settings JSON and give set the SERVER_NAME to match your DNS hostname of the server.

export METEOR_SETTINGS=$(cat ~/path/to/settings.json)
export SERVER_NAME=peakaboo.example.com

To Build the peakaboo docker container run:

docker-compose build peakaboo

CentOS 6: To divert docker's logs to syslog so that they are auto rotated and don't fill up the disk, make sure /etc/sysconfig/docker has:

other_args="--log-driver=syslog"

Then run peakaboo!

docker-compose up -d

When there's a change peakaboo you can update the docker images by stopping the containers and re building the images

docker-compose stop
docker-compose build peakaboo
docker-compose up -d

Client Side

To send/recieve data from the peakaboo app you will need to use a client that uses the Distributed data protocol from Meteor. You could write your own, or check out the examples in the docs directory: Peakaboo Plugins
