perfSONAR User Q&A and Other Discussion

["Garnizov, Ivan" <>]

Dear Debbie,

 

I see your inquiry as twofold:

-          You are having an issue with pscheduler test coordination

-          There is a bug in pscheduler on activating debugging mode for api

 

Your report about the bug will be reported to the pS Development team.

On the issue with pscheduler tests coordination please share your pscheduler request and pscheduler output.

An additional assistance to us would be, if you execute the pscheduler request with --debug options.

(Example)

pscheduler task --debug <<your test request here>>

 

As a workaround for the bug, you found, I would suggest to just run the commands below with sudo:

-          Activate debug: pscheduler debug on

-          Deactivate debug: pscheduler debug off

 

Regards,

Ivan Garnizov

Subject: [perfsonar-user] debugging pscheduler

 

I’ve been trying to work out why my two new perfsonar boxes can’t run througput tests with each other. My main clue is this in the logfile (both systems show the same error):

Apr  2 15:22:15 res-dtn journal: pscheduler-api INFO     Denied 2620:0:e01:8001::10 POST https://res-dtn.techservices.illinois.edu/pscheduler/tasks/b20f8a9a-502b-4070-8625-daf960bebc1e
Apr  2 15:22:16 res-dtn journal: pscheduler-api INFO     Denied 2620:0:e01:8001::10 POST https://res-dtn.techservices.illinois.edu/pscheduler/tasks



So I turned on debugging for the api in one of them, hoping to get more details about what was failing, with this command:


 pscheduler debug on api

which I found on this page:

http://docs.perfsonar.net/troubleshooting_overview.html


and got this in the log file:

Apr  2 15:58:14 res-dtn journal: pscheduler-api ERROR    Exception: IOError: [Errno 2] No such file or directory: '/run/pscheduler-server/pscheduler-api-debug'

Apr  2 15:58:14 res-dtn journal: pscheduler-api ERROR    IOError: [Errno 2] No such file or directory: '/run/pscheduler-server/pscheduler-api-debug'

Should I be able to turn on API debugging with that command, or did I need other settings?
