perfSONAR User Q&A and Other Discussion

[Antoine Delvaux <>]

Hi Cameron,

Accessing jitter data in Esmond is possible, yes.  If you want to try it I would direct you to the Esmond API documentation at https://docs.perfsonar.net/esmond_api_rest.html and this specific GitHub issue: https://github.com/perfsonar/project/issues/1216 

Another possibility, as mentioned by Ivan, is to send your measurement results into and Elasticsearch instance and use Kibana or Grafana to retrieve the data.  If you want to go that path I'd recommend you to have a look at this recording from TechEXtra 2020 perfSONAR day: https://www.youtube.com/watch?v=vmbST3YHenc that demo how to do it. This repository might also contain some useful information on how to set it up all together: https://github.com/perfsonar/archiving-sandbox 

That being said, we're starting development of a future perfSONAR release that should make all of this easier in the future. However we don't currently have any target release date to advertise.

Cheers,

Antoine.

Hello Ivan,

Do you have a recommendation for how to best access the jitter results from esmond? Or will I need to use a separate archiver?

NOTE: resending to include the mailing list.

Thanks,

Hi Cameron,

 

You are correct on the part that perfSONAR agents do collect and store jitter results from latency measurements.

Unfortunately the results of jitter are still not available as perfSONAR graphs. Still we are working on this and are looking to open up the pS architecture with an Elastic implementation, which is in our pipeline.

Subject: [perfsonar-user] Graphing/visualization of jitter in perfSONAR

 

Hello,

 

It seems perfSONAR is able to test and archive jitter levels, but the graphs that are built into the toolkit interface do not seem to include a dedicated visualization of jitter. I am looking at screenshots from this page in the documentation: https://docs.perfsonar.net/using_graphs.html

 

Am I mistaken? Is jitter also visualized in the toolkit web interface? Is the latency visualization intended to report on jitter as well?

 

Thank you,
