Profile remote applications
Remote profiling is the case when the profiled application and the profiler UI run on different machines, usually on a server and your developer machine.
See also Profile local applications.
1. Install profiler on the remote machine
Download and install profiler to the remote machine.
You can use command line tool to perform helpful profiling operations remotely.
2. Start profiling the application on the remote machine
Start profiling the application.
To ensure it has started with the profiler, check whether the profiler agent log file has been created:
<user home>/.ynp/log/<session name>-<PID>.log
If you want to profile Windows service, then it needs to be restarted. Special notes on profiling a Windows service can be found here.
3. Create new connection to the remote machine
To profile .NET applications running on the remote machine with agent use Profile remote application... action on Welcome screen or in "Profile" menu.

Specify the host name or IP address of the remote machine in the opened "Profile Remote Application" dialog.

Profiler discovers applications running with the profiler agent. Ports in the given range will be scanned. By default the profiler agent port is allocated in the range 10001-10010. If the profiler port was changed with startup option 'port', also change the Profiler agent port(s) field accordingly.
SSH tunnel
If the remote host is not directly reachable you can build SSH tunnel. To do so, navigate to the SSH Tunnel tab and enable SSH tunnel using Use SSH tunnel checkbox.

4. Connect to the remote application
Created connection will appear in the "Monitor Applications" list on Welcome screen under a given name. You can then connect to the application to perform profiling.

If you do not see your application it the list, please read profiling troubleshooting.
Please note that for SSH connections known hosts are not checked, and StrictHostKeyChecking
SSH parameter is set to no
