Hello Szymon,

I succeeded in publishing and performing measurements on local vmware hosts. But I still don't know why it failed  when executing the same commands on my cloud hosts (I've already turned the firewall off on both cloud hosts).

I have two cloud hosts and they both have public ip addresses, one ip address is 82.157.120.181 and the other is 49.232.21.90. 

On host "82.157.120.181", I executed the command:

# pscheduler task throughput --source 82.157.120.181 --dest 49.232.21.90

And I got a Failed result as shown below:

Then, I executed # pscheduler monitor on both hosts, and I got two different results:

on host "82.157.120.181", the result is:

but on host "49.232.21.90", the result is:

When I executed "psconfig publish template.json " on host 82.157.120.181, and "psconfig remote add "http://82.157.120.181/psconfig/template.json" " on host 49.232.21.90, if also failed to get the remote template.

I am wondering why this happened, maybe it's because I didn't configure HTTPS? Looking forward to your reply.

Is it possible that the cloud has some firewall in front of it that could block perfSONAR ports?

you can also try running "pscheduler troubleshoot 49.232.21.90" to perform basic pscheduler troubleshooting between the two hosts

Does $ curl -vk http://82.157.120.181/psconfig/template.json work for you  on host 49.232.21.90 ? If not the host will not be able to consume the configuration.

Please also look at /var/log/perfsonar/psconfig-pscheduler-agent.log to see if there are any errors that can tell more

Regards,
