Hi Renan,

Both, Dashboard and configuration beacon are based on the same JSON file, correct?

I have created a JSON file called confmesh.json available on https://193.49.159.188/confmesh.json.

You can see in it that I created 3 entry for hosts(193.49.159.188 on which I have installed persfonar and maddash, 195.221.27.242 which the remote beacon of a partner, and the last called th2-pp-c6-perfsonar-01.renater.fr which will be one on my futur beacon to deployed)

When I execute the generation of configuration for dashboard and configuration to be published for beacon, I have the following errors.

• [root@ix1-pp-c6-perfsonar-01 /]# /usr/lib/perfsonar/bin/generate_gui_configuration

your json file is missing "measurement_archives" section. json file is generated on a central server (Maddash server in your case) based on your mesh description in /etc/maddash/maddash-server/YOUR_MESH_mesh_config.conf (using /usr/lib/perfsonar/bin/build_json -o /YOUR_JSON_LOCATION/YOUR_JSON_FILE.json /etc/maddash/maddash-server/YOUR_MESH_mesh_config.conf). Can you show the YOUR_MESH_mesh_config.conf file?

Then you generate Maddash GUI configuration with /usr/lib/perfsonar/bin/generate_gui_configuration which result in .yaml file consumed by GUI

To make things easier before generating GUI config it's good to clear th default yaml file (/etc/maddash/maddash-server/maddash.yaml) and put there just this content:

# Set the directory where the database will be stored
database: /var/lib/maddash/
##
# Set the host where the REST server listens
serverHost: "localhost"
##
# Activate http and set the port where it listens
http:
    port: 8881
serverHost: localhost
