3. Basic Concept
2018/5/19
Use service monitoring data to feed service management decisions
Check if service management decisions have desired effects 3

4. Service Monitoring I HOW TO: enable a service for monitoring
2018/5/19
HOW TO: enable a service for monitoring
Expose data pertinent to certain criteria:
General behaviour (logging)
Performance (call frequency, current/mean processing times...)
Usage (current/mean user count...)
... 4

5. Service Monitoring II Sensor
2018/5/19
Sensor
actual software artefact exposing data about a service
according to one criterion (call frequency, processing time etc.)
Tackle middleware heterogeneity
Middleware-specific layer / concrete sensors
Middleware-agnostic layer / abstract sensors
Harmonisation
Abstract sensors available to all 3 middlewares 5

7. Service Management I HOW TO: make a service manageable
2018/5/19
HOW TO: make a service manageable
Add means to issue service management commands to service, e.g.:
Enable/disable service
Deploy/un-deploy a service
Change behaviour (e.g. employ a rule engine)
(Modify access control?) 7

8. Service Management II Graphical User Interface Browser-based
2018/5/19
Graphical User Interface
Browser-based
Used for monitoring and managing
Lists all monitorable and manageable EMI middleware instances
Retrieves monitoring data
Allows for executing management commands 8

9. Role of Messaging I Use Messaging to retrieve monitoring data

Use Messaging to
retrieve monitoring data
publish(Monitoring Data)
subscribeTo(Monitoring Data of 'X')
