Missing receiver-thoughput-bits value

[wfrischh]

Perfsonar Server: perfsonar.ligo-la.caltech.edu Kernel: 5.14.0-362.12.1.el9 Perfsonar version: 5.0.8-1.el9

We have setup a send/receive throughput test to two servers, perfsonar.ligo-wa.caltech.edu and perfsonar.ligo.caltech.edu. The summary results via the webpage, https://perfsonar.ligo-la.caltech.edu/toolkit/auth/, only reports the send throughput value.

When I replicate this via cli

[root@perfsonar ~]#   pscheduler task throughput -s perfsonar.ligo-la.caltech.edu -d perfsonar.ligo-wa.caltech.edu --reverse

However, the JSON data is showing receiver-throughput-bits as having a correct value

Running the throughput test without --reverse flag via cli returns a Receiver Throughput value:

Configuring Send Only and Receive Only Throughput tests via the webpage also only reports the outgoing throughput value.

Pinging for any updates or additional information needed.

This is being worked on.

Notes for reference

Because the JSON is generated by the participant, older participants won't do the corrected version and will result in zero, even on updated leads.

This might be overcome by making the merged-results method detect and correct for it.

This has been fixed and will be released with 5.1.0.
