Hi ChanJin Park,

 

Please note pS 4.0 has still not reached final release state, so it should be expected to have some deficiencies.

You have to keep in mind and understand, that pS 4.0 will bring a totally new experience on test coordination and test trigger process. Namely pS team introduces a new scheduler service – pscheduler.

From your email it does not become clear, if the remote system is also pS4.0 RC2 deployment.

In all cases information about the events and possible issues should be sought in /var/log/pscheduler/pscheduler.log

 

To be able to further help you it would be nice, if you can provide us with the configuration in /etc/perfsonar/meshconfig-agent-tasks.conf

Please make sure you remove the password fields, if there are any.

 

With regards to your verification test: As I have noted the pS 4.0 introduces a new coordination mechanism/tool pscheduler. Your test currently demonstrates only that your system is still able to coordinate a measurement with older pS releases.

 

Dear ChanJin Park,

In addition to what Ivan has just written 1 minute interval between throughput tests is a bit too challanging both for host and the network. Consider limiting it to less frequent tests (we usually run them every few hours).

You may want to look at /var/log/httpd and /var/log/esmond for some errors

Are the regular test processes visible when you do ps -ef | grep pscheduler?

Regards,
