perfSONAR User Q&A and Other Discussion

Hi Marcos,

The problem is the way that MaDDash queries Esmond so unfortunately splitting the meshes won’t help (which you observed). In Esmond, it does indeed separate your tests but when MaDDash queries Esmond it asks for “all throughput tests matching a given source, destination, and protocol” by default (it also will check ip version, tool and bandwidth if any of those are explicitly set in your pscheduler test definition). It does not currently filter by congestion control algorithm.

If you are feeling adventurous, attached is a file I think will get you closer to what you want. It won’t fix the graphs MaDDash displays, but will fix the nagios checks that color the MaDDash boxes. Copy the attached file to /usr/lib/perfsonar/psconfig/checks/ps-nagios-throughput.json and restart psconfig-maddash-agent. That is the file that tells MaDDash how to build the Nagios check. The updated version has some blocks that pull the “congestion” parameter out of the pscheduler test spec and pass it to the generalized —filter parameter in the Nagios check that tells it to look at the “pscheduler-throughput-congestion” field in esmond. I have not tested this but in theory should work.

Thanks,

Andy

Hi guys. We are creating two throughput meshes to compare BBR and CUBIC, it seems that both tests are running, but maddash was showing the same results on both meshes.

Is this an unsupported scenario? Is there suggested way around?

 

We tried using two different dashboard for each test, but they still show the same information.
