• public long lastActivity;

• public long lastActivity();
  
  

Every implementation of SystemThread should update a lastActivity field on each pass through the main loop. For simplification, it might be a time field.
Interfaces GridWorker and IgniteThread are looked as good candidates to extend this interface.

This interface should specify: 

• private static final long systemThreadTimeOut = 5_000;
• public List<SystemThread> systemThreadsList;
• public void register (SystemThread t); to add a system process to watchdog monitoring
• public void unregister (SystemThread t); to remove a system process to watchdog monitoring

...

• public void checkSystemTread (); to check a state of registered system processes
