JASMINe 2008


Managing distributed system is a difficult task

- Configuration

- Distributed platform (SOA

platform/Java EE Cluster)

- Numerous files due to products

assembly (JOnAS = 46 files)�

- Heterogeneous formats (XML,

properties, …)�

- Monitoring- Huge number of events to monitor

– Distributed architecture– Multiple levels

!!! Not manageable by humans !!!


Consequence

- Human actions are error prone- 40% of the interruptions of service- Service interruption cost funding

M $ lost per unavailability hour

- Low reactivity- Administration tasks costly

- Consumes a lot of resources• Human resources : Required skills are rare, > hardware cost• Material resources : Overbooking (estimation in the worst case) �


Strong requirements for a smart tool

- Simplify the administration tasks- Reduce the errors (avoid human errors) �- Improve the reactiveness/QoS

• And so the applications availability

- Minimize the human and material resources cost


Agenda


JASMINe 2008


JASMINe, big picture

- JASMINe Design- Graphic tool for building a

middleware configuration

- JASMINe Deploy- Framework for deploying a

middleware configuration

- JASMINe Monitoring- Tools for performance tracking and

error detection

- JASMINe Self-management- Control loop for Self-optimization &

Self-healing


Agenda


JASMINe 2008


Monitoring activities

- Realtime monitoring- Check the system health, performance analysis,

error detection- High reactivity

- Tactic monitoring- Check the system behavior over a long period of

time• Leaks (memory, threads, connections, …) �• Bottlenecks

- Low reactivity (a few days/weeks)�

- Strategic monitoring- Capacity planning- Very low reactivity (a few months/years)�

MBeancmd for monitoring the JOnAS MBeans

- Available in JASMINe 1.0- Java command (mbean.jar), enables

scripting- Relies on the JMX Remote interface- Capability to :

- get and set MBean attributes- invoke MBean methods- poll any MBean

- Shortcuts for probing the most relevant JOnAS indicators

- Tx,datasource, http connectors, threads pool, jms statistics, …

- File storage (CSV) or database- Replay mode- Graphic console

Error detection

- Relies on the engine rules Drools- Enables to implement the user’s

management policy- A few rules examples :

- Error logs aggregation- Counter aggregation- Cpu overload detection over a significant

period (ignore peak load) �- Memory saturation is close- Datasource bottleneck - Alarms burst filtering- Multiple error events correlation for

determining the in-fault component- Actions : alarm generation, mail sending,

… may be extended

Principles

- Eclipse EMF/GMF for describing the cluster configuration (RCP GUI)�- Jade/OSGi for deploying the configuration across the infrastructure

1. Describe the middleware configuration

2. Deploy the middleware configuration
