perfSONAR User Q&A and Other Discussion

[Daniel Manzo <>]

Hi,

 

I am currently running the most recent version of the perfSONAR toolkit on an already existing RHEL 6.8 virtual server for testing purposes. I recently changed the values of max_heap_size and heap_newsize in the file /etc/cassandra/conf/cassandra-env.sh in order to get Cassandra up and running after having problems before. This worked, however, when clicking the “Details” link underneath the test source to see the statistical graph, I am getting an error: “Error retrieving data from the webservice.” I have restarted httpd, postgresql, and Cassandra at times, but it only works when loading the page. After clicking the “Details” link, Cassandra’s status is reported as dead and I get an error. Attached is the Cassandra.log file for when it was reported as running.

 

Best regards,
