Hello Victoria,

 

Your questions are actually not that simple / basic.

1)      The GUI you refer to is actually part of the pS Toolkit bundle, which is actually the most sophisticated solution we provide. The Toolkit solution incorporates almost all of the features of the pS ecosystem. It is designed to ease the use and hide the complexity behind interdependent services.
Still if you are looking for all the options of the pS solutions, then you’d better consider the core pS components and customize the pS framework to your needs.

To add to this is that the GUI can currently only take you so far and there are a whole bunch of options perfSONAR allows you too set that are not available in the UI. All of the tests are defined in a JSON file we refer to as pSConfig templates (or often call a “mesh file”). More details on that process can be found here: http://docs.perfsonar.net/#managing-multiple-hosts-with-psconfig. There is also a more advanced GUI for defining tests here: http://docs.perfsonar.net/pwa.html


2)      
Refer to point 1 and you’ll understand why the pS Toolkit system is so resource hungry. I am not sure what you mean with “limitations regarding performance”. We do not set limits for the operation of pS services. Actually perfSONAR pS is just the orchestrator of many popular tools for network performance testing. We do not manipulate or limit these tools by any means.

RAM is always the first thing to go, and 4GB is the minimum we suggest. The biggest user of resources is the database that stores the results. This is why many people run the “testpoint” bundle that does not include local storage and send results to a central server. 



3)      
There is no official support for Grafana from pS dev team yet… I am not sure we are going to provide ever such. Still we are working towards opening the pS services to be able to provision data-analysis stacks based on ELK, which also includes Grafana, but we are not there yet.

Just to reiterate, we are moving toward this but are not there yet.

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,
