How to debug ODENOS

Refer to the following debugging tools:

Java

• jconsole for CPU/memory/thread monitoring
• Remote debug using Eclipse
• Memory Analyzer(MAT) for Eclipse for memory usage check

Python

• winpdb for debugging python like Eclipse remote debugger.

Other tools

• ODENOS CLI for interactive CRUD operations with ODENOS REST APIs and stress testing.
• Uncomment "monitor" or "monitor.logging" options in etc/odenos.conf.
• ODENOS monitor to generate message sequence diagram.
• Redis CLI to check pubsub-related messaging.
• zkCli for checking statuses of remote objects (RemoteObject).

Tips

• If some strange behaviors are observed, type "./odenos stop" and check if all the ODENOS processes (Linux processes) have been terminated successfully ("ls /tmp" or "ps a").
• Check if Redis server (tcp port 6380) is running.
• Check if ZooKeeper server (tcp port 2181) is running (it runs in ODENOS's JVM as an embedded data base, unless you comment out "zookeeper.embed" in "etc/odenos.conf".
