The Monitoring and Debugging Dashboard (MaDDash) is a tool for collecting large amounts of inherently two-dimensional data and presenting it in visually useful ways. The project consists of the server side that schedules jobs to collect data and a web front-end to display that data. A summary of the collected data is also made available as a JSON REST API. This initial use case was collecting point-to-point network measurements published by perfSONAR and displaying them as an organized collection grids on the web front-end. These were presented with one endpoint as the row and the second endpoint as the column. In principle though, MaDDash can be extended to support any two-dimensional data.

MaDDash is available as an RPM and this is the recommended method of deploying MaDDash on a production host. See our Install Guide for more details.

Contributing There are multiple ways one may want to contribute including:

• Updating the data collector
• Updating the existing web interface
• Writing new clients to the JSON REST API

The subsection are for developers wishing to get involved in one or more of the ways above.

This repository allows you to use Vagrant to create a VM on VirtualBox with the necessary components installed. The default VM is based on CentOS 7 and creates a shared folder in the VM that points at the top-level of your checked-out copy. This allows you to edit files on your base system and have the changes automatically appear in the VM.

1. Install VirtualBox according to the instructions on their site for your system.
2. Install Vagrant according to the instructions on their site for your system.
3. Install the vagrant-vbguest and vagrant-reload plugins with the following commands:

   vagrant plugin install vagrant-vbguest
   vagrant plugin install vagrant-reload
   

4. Clone the MaDDash github repo (including git submodules with --recursive):

   git clone --recursive https://github.com/perfsonar/maddash
   

5. Start the VM with vagrant up. The first time you do this it will take awhile to create the initial VM.

You can login to the VM with the following command:

vagrant ssh

You can start MaDDash with the following:

systemctl start maddash-server

A build was done during VM creation and the version running will be based off the Git copy you have cloned locally. If you want to rebuild the packages and test new changes to the maddash-server run:

cd /vagrant/maddash-server
mvn clean install
systemctl restart maddash-server

For changes to the web UI simply make you changes to the files under maddash-webui.

• Any changes you make to the checked-out code on your host system get reflected in the host VM under the /vagrant directory

• The following symlinks are setup to files in the git copy of the code:

  • /etc/maddash -> /vagrant/vagrant-data/maddash-el7/etc/maddash
  • /usr/lib/maddash -> /vagrant/vagrant-data/maddash-el7/usr/lib/maddash
  • /usr/lib/maddash/maddash-webui -> /vagrant/maddash-webui/web
  • /usr/lib/maddash/maddash-server/target -> /vagrant/maddash-server/target
  • /usr/lib/maddash/maddash-server/bin/*.sh -> /vagrant/maddash-server/bin/*.sh

• Run vagrant reload to restart the VM

• Run vagrant suspend to freeze the VM. Running vagrant up again will restore the state it was in when you suspended it.

• Run vagrant halt to shutdown the VM. Running vagrant up again will run through the normal boot process.

• Run vagrant destroy to completely delete the VM. Running again vagrant up will build a brand new VM.
