---------------------------------
Summary: Replace JMX statistics collecting with Karaf Cellar events
Key: UNOMI-136
URL: https://issues.apache.org/jira/browse/UNOMI-136
Project: Apache Unomi
Issue Type: Bug
Components: core
Affects Versions: 1.2.0-incubating, 1.1.0-incubating, 1.0.0-incubating,
1.3.0-incubating
Reporter: Serge Huber
Assignee: Serge Huber
Fix For: 1.3.0-incubating
Currently we use JMX (on top of RMI) to connect to the other cluster nodes and
retrieve their system statistics such as CPU Load, Load Average and Uptime. The
problem with this is that it uses an RMI server internally that caches IP
addresses of cluster nodes, and if the network configuration changes (for
example on a laptop that moves from one network to another), the RMI server
still uses the old cached IP addresses.
The idea is to replace an JMX/RMI based system with one that uses Karaf Cellar
Cluster Events (that use Hazelcast for communication) that will not be subject
to the same issue of IP address caching.
