I am trying to set up a server which I can use to do manual, single
performance tests with public perfsonar servers.
…
Can anyone give a simple example how to run a performance test with an
external, public perfsonar server after installing only perfsonar-tools?

 

Sure.  Starting with a fresh AlmaLinux 9 system:

 

$ curl -s https://downloads.perfsonar.net/install | sudo sh -s - tools

 

…Many lines of output…

 

$ export PSCHEDULER_ASSIST=denv.ps.internet2.edu

$ pscheduler task rtt --source clev.ps.internet2.edu --dest ashb.ps.internet2.edu

Submitting with assistance from denv.ps.internet2.edu...

The PSCHEDULER_ASSIST environment variable  and using the  --assist switch  with pscheduler task are equivalent.

 

As far as I understand in the docs I have to use pscheduler … And even if I install pscheduler-server, I don't get it to work because
the pscheduler-server does not offer any test tools.

 

The pscheduler-server package is one piece of a larger puzzle.  The plug-ins that make it able to understand what the tests are and able to carry them out are packaged separately.  There is a package called pscheduler-bundle-full that will install the server and all its plugins.  It’s not something we officially recommend, but it will give you a standalone, pScheduler-only system.
