perfSONAR User Q&A and Other Discussion

[Victoria Villa Valle <>]

Good morning,

We are starting with a migration project from Cisco IPSLA to another type of Software, and one of the options we have been working with for a few months is Perfsonar since being an open source tool with several possibilities (not only IPSLA measurement) it can be used as an evolution of Cisco's legacy tools.

We are starting with tests that report the jitter to us, specifically the icmp jitter and the TWAMP that we see that the tool has (We do not know if there may be any that report the one-way as well as the udp-jitter other than the TWAMP in Perfsonar). We are doing the tests between two ubuntu servers with Perfsonar installed.

 

With these tests, and as new users, we have different doubts :

1) Is possible via GUI configure more “Advanced options” (like DSCP) . We just see the packet rate and size . Is there a different GUI that includes more options?

 

 

2) Our network is made up of many devices, requiring 80K tests (120 probes with 6 different QoS meshed together). Running a single test ( the one shown above) we see that the device suffers in terms of RAM (the equipment is dedicated only for these tests). Are there any limitations regarding performance? Is there a test on how much a Perfsonar agent supports? Sometimes the CPU usage is 1.5%

 

 

3) We have seen that in the latest versions of Perfsonar support for Grafana has been added. Would this be the best way to attack this data? Is there any guide for collecting API data?

 

 

Sorry if they are very basic questions, but we have not found very clear solutions to them, and being new users we are a bit stuck with it.

 

 

Kind regards,
