run list remotely not showing exec servers...

[Chris]

Im pretty sure I have my scheduling/storage server configured correctly. On test runners of each machine, I see that I am connected to the correct scheduling server too. Ports are open, no firewall exists, etc. When I try to run test remotely on my stand alone client, the list is empty. Below is an exception I noticed in the log when trying to load that Run Test Remotely pop up screen:

I'm assuming this has something to deal with my issue at hand. I can provide more information/details if necessary. Any help with this issue would be greatly appreciated - thanks in advance.

Also wanted to include this snippet found in the error log:

Hi Chris,

Thank you the case details provided.

Once you connected all remote execution clients to the scheduling server and press on Run Remotely all execution clients machines should be listed to choose where to execute the test list.

It is possible that at some point that the scheduling service is not acting normally and it is recommended to restart it from the machine where scheduling server is configured. Then re-connect the project to the scheduling server.

To eliminate the project related problem and test just the remote set up - try to create sample test with 1 or 2 steps in a new test list and run it remotely.

Let me know if this solves the problem and if there is other exception you got there.

Thanks for the information Nikolay. I was able to get it up and running and connected after updating the URL's - i was pointing to localhost on the machine with scheduling/storage when I should have used the host name instead. Also had to point to port 8492; for some reason the default port number was pointing to another number.

Hi Chris,

Thank you for the feedback. I'm glad the case is resolved.

Somehow I have came back across this issue and have had no luck fixing it.I successfully connect to my scheduling server without any issues. When i view the log, i noticed this:

What exactly causes this error: Error trying to populate drone status collection.?

[Nikolay Petrov]

Hi Chris,

I'm sorry to hear that a similar problem is up again.

This problem seems to be related to miss function of the scheduling server. For some reason it does not respond appropriately. Try to restart the scheduling service and the execution agents on the remote machines as well.

I hope this will solve the issue.

Trying that right now - shutting down storage / scheduling / execution on my virtual machine box (VM1), will terminate execution server and close stand alone on my local work station, will Start both storage and scheduling again on VM1, then Configure scheduling server, start everything, then start execution server on VM1, then will go to my work station and open up stand alone, connect project to scheduling, after success will run test remotely and see if VMs appear in list...

[Chris]

After restarting everything, the logs looked good so far until I opened up the stand alone on my machine and viewed the logs and this appeared:

I made sure I opened up this inbound port on my machine. Is there something that I'm missing?

I have my workstation that has a stand alone copy and a virtual machine that has scheduling+storage+run time installed. On both machines, I see test runners properly configured and pointing at the right scheduling connection. On my workstation machine though, I noticed on the Scheduling tab, it is listening on localhost:8009. Is this supposed to be my VM's scheduling service URL? On my Execution tab however, it is pointing  at the correct scheduling connection URL on the VM...

[Nikolay Petrov]

Hi Chris,

If there are active firewall try to stop it to confirm if the closed ports are the problem. All ports that supposed to be open in order the scheduling server to communicate normally with the remote agents are listed at the bottom of this article. 

The recommended port for the scheduling service is 8009 indeed.
