perfsonar development work

[David Schmitz <>]

Hi all,

from the discussions in the last week about the new schema for 
the Input Errors/Packet Drops MA the following conclusions were drawn:

For the implementation which will start soon on Monday
the schema described by the following example instance and rnc files
will be used:
http://anonsvn.internet2.edu/svn/nmwg/branches/snmp/rnc/errors.rnc
http://anonsvn.internet2.edu/svn/nmwg/branches/snmp/rnc/discards.rnc
http://anonsvn.internet2.edu/svn/nmwg/branches/snmp/example_instances/errors
http://anonsvn.internet2.edu/svn/nmwg/branches/snmp/example_instances/discards

This version of the schema is similar to the already existing schema for
the utilization MA.


In the future a new version for the schema will be used, which will be a 
unified approach comprising any possible metric covered by SNMP data
collection, i.e. utilization, input errors, drops, and any further SNMP 
metric.

The development of this later used schema version is ongoing work.
Currently, there are the following open issues:

- use of supportedEventType parameter instead of eventType element 
  in store file (metadata config file).
- support of multiple event types in one metadata block?
- new time formats for select parameters, in addition to UNIX/ISO formats
- issues concerning the chaining of metadata elements 


Regards,
David
