perfSONAR User Q&A and Other Discussion

["Andrew Lake" <>]

Hi Ivan,

Despite appearances, this may or may not be an issue (or at least a temporary one). This usually happens when the ls_registration_daemon tries to register the same record twice. It usually corrects itself the next run when the old record expires. Are you trying to debug a missing record or were you fishing through the logs again and found this?

Thanks,

Andy

Dear perfSONAR developers,

Please give some hints, guides on the case with LSRegistrationDaemon getting 403 Forbidden.

1) Is that a service response from the LS server? I exclude firewall or connectivity issues.
2) What would be the cause of this or in which case and how does one intervene or assist the registration process? Please do not ignore possible actions on the LS server for the resolution of the case.


ERROR> Base.pm:304 perfSONAR_PS::LSRegistrationDaemon::Base::register - Problem registering service. Will retry full registration next time: 403 Forbidden

Best regards,
Ivan

Hi Ty,

In fact I have reported the same issue about my instances. Issue tracker. https://github.com/perfsonar/regular-testing/issues/5
Suddenly out of no reason, without any notable event in the logs the regular_testing service stops collecting the data. I have also noted that a single service restart does not help. You have to follow a graceful restart....meaning:
sudo service regular_testing stop
sudo service postgresql stop
sudo service cassandra restart
sudo service postgresql start
sudo service regular_testing start

This immediately fixes all measurements. I have tested that on 2 hosts.
We still might be in different scenarios, although my issue is also around the latency tests.

Best regards,
Ivan

All my hosts are running the same (lastest) versions of the tools and they're all sync'd with the same NTP sources. Instead of restarting the whole regular testing service, I've taken to killing the individual bwping process, regular testing fires up a new process and everything clears up.
