perfSONAR User Q&A and Other Discussion

[Alan Whinery <>]

As I just shared with Andrew K.:

An unfinished (never to be finished) yet possibly-useful Perl script for fetching owamp results from an old-style-XML perfSONAR MA is at:

http://net.its.hawaii.edu/network-performance/owamp-summary/

it has a couple of unimplemented features that are mentioned in the syntax message, but works as described in the README.

It uses no Perl modules not in most standard Perl base-packages, parsing XML with regex.

In short, what it will do is allow you to ask an MA for all test results in a time period, and return them in a CSV format.

The reason I say "never-to-be-finished" is that even if I spend more time on such things, it would be much better to work with the new MA interface.

YMMV/no warranty, but maybe I can answer questions. It does not quite generalize to fetching bwctl (iperf) results, but there wouldn't be much to do to make that work.

Alan and Andrew,

I am interested in exporting owamp data for the use of statically generating graphs for research documents.  I have some experience interfacing with the SOAP interface and was just curious if there was an alternative option.

Thank You,

Andrew Koerner

It's an interesting time to ask this question, given that the work that
has been done for querying a perfSONAR measurement archive (through the
external interface, rather than SQL), has been mostly with the old
SOAP/XML type interface, and yet the new RESTful interface should be
easier to interface with, so presumably, there may be tools coming.

Can you say what measurement data you want to export, and how often, or
otherwise set up the situation?

I think that you will find many users who agree that an export tool
would be useful.
