perfSONAR User Q&A and Other Discussion

[Michael Johnson <>]

Hi Jon,

I just tested this on a 4.0.1 host which I upgraded from 4.0. As far as I can 
tell, it's working correctly.

However, the main part of the fix for the ping latency issue was in the 
pscheduler-archiver-esmond package. There was a missing summary window. Also 
note that once you upgrade that, you should see values from that time forward 
(it doesn't retroactively add the missing window on old data).

What version is your perfsonar-archiver-esmond?

On the test host I mentioned, I see:
Version     : 1.0.1.1

By the way, it's expected that "bundle.js" on git may not match the installed version. 
This is because bundle.js  is built using npm and the results are then committed to github. 
However, during the RPM build process, the "bundle" file gets rebuilt.

Thanks,
Michael
