perfSONAR User Q&A and Other Discussion

["Garnizov, Ivan" <>]

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,
