perfSONAR User Q&A and Other Discussion

[Alex Moura <>]

It would be useful if there was a some standard format to exchange information about events (e.g.: between TTS, NMS, SDN Controllers etc). 

I wonder if the RFC7970 can be used for this purpose in case there is no other specific alternative available?

Hi Michael,

We have a few long-haul links, and we have at least one network event per day involving these links. In our vision, our SDN controller could be extended to upload these network events to perfSonar via REST or later via CSV file. Then, it would be easier to correlate events.

I will be waiting for this feature! Thanks for your feedback!

Hi Jeronimo,

We have an open issue requesting something similar:
https://github.com/perfsonar/graphs/issues/4

Your request is a little different in that you want to import the data rather than manually entering it, but this seems like a logical feature to add to it. This feature has not yet been planned for a specific perfsonar release, so nothing has happened with it yet. As described, it's pretty involved to add. It might be possible to do a subset of the functionality in a shorter timeframe, but it's unlikely to happen in the near future (4.1 at least is already planned out).
Thanks for the feedback!

Hi All,

I really liked the new perfSonar charts, specially the interactive part of it. I was wondering how complicated would be to add more info to those dynamic charts, to try to correlate with network events. For example, if one of the links flaps (which could add errors to a specific OWAMP test running), how could I reflect that into our charts? This would allow me to easily correlate events.

How complicated would that be in case I have all network events in a CSV or JSON file? I just need to print a dot indicating that something external happened at that time.

Thanks,
Jeronimo
