Package com.google.jenkins.plugins.computeengine

Class ComputeEngineMonitor

java.lang.Object

java.util.TimerTask

hudson.triggers.SafeTimerTask

hudson.model.PeriodicWork

hudson.model.AsyncPeriodicWork

com.google.jenkins.plugins.computeengine.ComputeEngineMonitor

All Implemented Interfaces:

ExtensionPoint, Runnable

@Extension
public class ComputeEngineMonitor
extends AsyncPeriodicWork

Periodically checks and maintains minimum instance count for each GCE cloud configuration. This serves as a backup mechanism since minimum instances are normally created automatically when an event happens (example: reaching a milestone in jenkins startup, agent is allocated to a build, etc.)
