    hello,
      
      
      I am trying to create a perfsonar infrastructure for a school
      project, but i am a bit lost in the documentation about how to
      install and configure the different components.
      
      
      I want to have a central management node on a VM and several
      raspberry pi that send test result to the central management node.
      
      
      
      I successfully installed the toolkit with the full iso and I added
      the central-management bundle, and installed perfsonar-testpoint
      on raspbian on my pi.
      
      
      I tried to add some tests from the web UI but I can see the test
      in the raspi log with journalctl, but nothing in the test-result
      section on the web UI.

      I don't really understand how the templates work, and if I need to
      install maddash over pscheduler, or can I get the test results in
      the standard web interface?

Dear Joel,

The very general idea would be to have (see also http://docs.perfsonar.net/install_options.html):

1) measurement nodes (in your case RPi) where you install either a full Toolkit (then you have GUI) or just perfsonar-testpoint bundle that gives you the measurement node with CLI able to participate in a centrally managed mesh. There will be no local data storage.

2) central archive + Maddash where you install perfsonar-centralmanagement bundle (includes archive and dashboard). You don't install a Toolkit here. The archive will store the data coming from measurement nodes and Maddash will present them. This host will also be used to publish mesh configuration template.

Before you start any mesh configuration I suggest you test and verify:

- nodes are able to run tests between them (from CLI commands)

- necessary ports are open on FW in order to run tests and access the central server (see http://docs.perfsonar.net/manage_security.html)

Then you may approach to configure your mesh. See "Managing Multiple Hosts with pSConfig" sections in documentation but for a quick guide look at "MaDDash Quick Install Guide" link in "Displaying Measurements with MaDDash" section.

regards,
