In my environment it's not (easily) possible to install the Neoload Controller alongside Jenkins on the same host.
Is there a way to invoke Neoload on a different machine via the provided Jenkins plugin? Perhaps using SSH?
NeoLoad does not have to be installed on the Jenkins server. Of course you can install it on a remote machine and use that machine as slave in Jenkins. If it's a Linux machine SSH is a way to connect the slave.
In your NeoLoad Job configuration you just need to setup the path of NeoLoad controller based on your remote machine installation path.
