I used psconfig web admin to create the template, so I used the URL to the json as the remote, here it is:

and here is the yaml file, I didn't edit it, but I see the grids[] is empty while it shows them in psconfig maddash-grid list, do I need to add them manually?

Hi,

this was a stupid error, I used http for the remote add while it was only available on https. Now it has the right URL, the tests run and I can see the results in the archive, but I still don't see my grid, I have an error in the /var/log/maddash/psconfig-maddash-agent.log:

2020/03/02 07:37:38 ERROR pid=19963 prog=main::__ANON__ line=131 guid=B10490FA-5C58-11EA-B0FC-8A8BC0EB086C
msg=Died: Can't use an undefined value as an ARRAY reference at /usr/lib/perfsonar/bin/../lib/perfSONAR_PS/PSConfig/MaDDash/Agent.pm line 245.

I tried to look at the code but I don't know perl and I don't understand where the problem come from

On the central server the Maddash agent is running and is responsible for automatic generation of MAddash config to /etc/maddash/maddash-server/maddash.yaml.

To verify it correctly points to the config run in your central server:

$ psconfig remote list

It should list the path to your local .json psconfig template ffile with the header "=== MaDDash Agent ==="

You may also want to share the generated maddash.yaml file. Did you modify it manually?

Regards,
