perfsonar development work

["Nina Jeliazkova" <>]

Hi Yee, 

There are some examples on wiki page
http://wiki.perfsonar.net/jra1-wiki/index.php/Measurement_Archive_Protocols

In PerfsonarUI, interface names (and other info) are retrieved by an 
empty MetadataKeyRequest.

<?xml version="1.0" encoding="UTF-8"?>
<nmwg:message id="whatever" type="MetadataKeyRequest"
xmlns:netutil="http://ggf.org/ns/nmwg/characteristic/utilization/2.0/";
xmlns:nmwg="http://ggf.org/ns/nmwg/base/2.0/";
xmlns:nmwgt="http://ggf.org/ns/nmwg/topology/2.0/";
xmlns:select="http://ggf.org/ns/nmwg/ops/select/2.0/";>
  <nmwg:metadata id="meta1">
    <netutil:subject id="iusub1">
      <nmwgt:interface/>
    </netutil:subject>
    <nmwg:eventType>utilization</nmwg:eventType>
  </nmwg:metadata>
  <nmwg:data id="dataID" metadataIdRef="meta1"/>
</nmwg:message>

You could try it at Playground tab on the perfsonarUI (perfsonar.acad.bg). The
response is MetadataKeyResponse consisting of details defined for all
interfaces of the queried MA.

Hope this helps,
Nina
