perfSONAR User Q&A and Other Discussion

[Michael Reece <>]

I have a pretty weird problem. All of the testing done on my 6 node mesh is through a central configuration file. But oddly, every single one of the the nodes in my mesh are missing an agent_configuration.conf at the path /perfsonar_ps/mesh_config/etc/

From my understanding, the agent_configuration.conf tells the node where the URL of the mesh.json is located, allowing the nodes to perform the tests. I really don't understand how it is possible for nodes of my mesh to be working with the agent_configuration.conf missing, but I promise you that they are. Moreover, all of my scripts are missing (build_json, generate_configuration, validate_configuration, etc.)

I find this very confusing and don't understand 2 things:

1. Why did my agent_configuration.conf, scripts and basically everything in the directory mesh_config suddenly disappear from all 6 of my nodes?
   
2. How are these nodes able to communicate with MaDDash without an agent_configuration.conf being present?

I wouldn't care so much about this if I wasn't trying to add another node to the mesh and having trouble doing so. I think it may be because the new node doesn't have the agent_configuration.conf but that begs the question of how the other nodes are functioning.

If you would like to see the mesh.json, MaDDash.yaml, or any other file which may help diagnose the problem, please ask and I'll gladly attach it.

Thanks in advance
