Thanks for giving me a place too look.

It is running.

This is a fresh install with some tests added. Did I miss something when installing? Thanks

Hi Thomas,

 

The link you provided shows a failure for the Esmond archiver.

This apparently leads to the issues you report with the pS GUI.

 

So what do you have in the Cassandra logs?

/var/log/cassandra/system.log

 

Are you sure Cassandra service is up and running?

 

Could that be a resource exhaustion problem?

From your messages we can only guess, but do you run the pS Toolkit? How did you install it / what procedure did you follow?

 

 

Regards,

Ivan Garnizov

No, I think it was the migration script (from CentOS . I did reinstall and could manually add the tests and it saved fine.

I have an error in the Test Results  page.

Error loading test listing; measurement archive unreachable:

I did find this in the /var/log/httpd/error_log

Was this a result of a pSconfig command, or some other operation?
