perfsonar development work

[Charaka Palansuriya <>]

Hi Eric, Jeff, Joe and others,

Let me introduce myself. My name is Charaka Palansuriya and I am the 
project leader (as well as a technical developer) for the JISC Network 
Performance Monitoring (NPM) project.

Nicolas mentioned that you are interested in learning more details about the 
JISC-NPM's Alarms Service work. I put together a document that explains the 
following in the context of an Alarms Service for LHC-OPN,

  1) List of alarms conditions to be monitored
  2) List of requirements
  3) Preliminary high level architecture
  4) Brief explanation of the prototype we are
     currently building
  5) Questions (with answers we received so far)

Please note that the work is still at an early stage. We are presently 
proceeding with building a prototype. Based on this experience and feedback 
from LHC-OPN, WiN-Labor, perfSONAR developers such as your selves and others, 
we may alter architectures as well as the underlying design and technology 
used.

Therefore, we would greatly appreciate if you could have a look at the attached 
document and provide feedback to us. In particular, we are looking for

  * Tips on analysing network measurement data (aggregation, any pitfalls?)
  * Performance considerations (how much/often can we query)
  * Ways of alarm notification?
  * What information should an alarm contain?

Thanks in advance for your replies.

Charaka
(On behalf of the JISC-NPM team)
