perfSONAR User Q&A and Other Discussion

[Daniel Manzo <>]

Hi all,

 

I am currently running perfSONAR v4.0 on RHEL 7.3. I was previously having problems with postgresql-9.5 and pscheduler, but now those are resolved and both are running smoothly. However, I cannot access the toolkit from HTTP, only HTTPS. Also, when I access the web page, I am getting “Error loading test listing: Internal Server Error” underneath the “Test Results” section. I have checked the logs, and I’m not seeing any real evidence where this problem could be located.

 

Here is something that does not look good to me, especially since Cassandra is running (clean_esmond_db.log):

No handlers could be found for logger "esmond.api.perfsonar.api_v2"

Unable to connect - presuming stand-alone testing mode...

Traceback (most recent call last):

  File "./util/ps_remove_data.py", line 74, in <module>

    from esmond.api.perfsonar.api_v2 import EVENT_TYPE_CF_MAP

  File "/usr/lib/esmond/esmond/api/perfsonar/api_v2.py", line 65, in <module>

    raise ConnectionException(error_msg)

esmond.cassandra.ConnectionException: 'Unable to connect to cassandra. Please verify cassandra is running.'

This also worries me (from meshconfig-agent.log):

2017/06/28 14:16:55 (16717) WARN> perfsonar_meshconfig_agent:145 main::__ANON__ - Warned: Use of uninitialized value $address in exists at /usr/lib/perfsonar/bin/../lib/perfSONAR_PS/RegularTesting/Tests/BwctlBase.pm line 384.

Also, esmond.log shows this error multiple times:

2017-06-28 14:22:17,198 [ERROR] /usr/lib/esmond/esmond/api/perfsonar/api_v2.py: Unable to connect to cassandra. Please verify cassandra is running.

 

Any and all help is appreciated. I’m guessing there must be a problem with esmond, but unsure where to start.

 

Thank you,

Dan Manzo
