The Problem: No Management
Companies doing
Management
Companies not
doing Management
3
The Problem: Reasons
• Tools are expensive
• Tools are hard to use
• Tools are normally both
4
The Solution: Tools!
• What? More tools?
• We aim to produce a tool:
– Free
– Very easy-to-use tool
– That does 80% of management tasks
for small to medium networks
5
Goals and Requirements
• Have what the old tool had:
– Web interface, SNMP, maps, color
coded alarms, performance graphs,
alarm logging and notification
•
•
•
•
•
Ease of use
Scalability
Extensibility
Portability
Very low Total Cost of Ownership
6
Immediate Goals
• Everything but ease-of-use
– That will have to come later ...
7
Architecture
• Component-based framework
– For extensibility
– To allow “Visual Building” of
management applications through
plug-in components

Current State & Future
• Initiating production use
– http://artemis.dsc.ufpb.br:8084
• Not easy to use yet but
– Working hard on automatic
configuration
• Very flexible architecture
• About a year away from public
release
