Package org.jenkinsci.plugins.cloudstats

Class CloudStatistics.ProvisioningListener

java.lang.Object

hudson.slaves.CloudProvisioningListener

org.jenkinsci.plugins.cloudstats.CloudStatistics.ProvisioningListener

All Implemented Interfaces:

ExtensionPoint

Enclosing class:

CloudStatistics

@Extension
public static class CloudStatistics.ProvisioningListener
extends CloudProvisioningListener

Listen to ongoing provisioning activities.

All activities that are triggered by Jenkins queue load (those that goes through NodeProvisioner) are reported by Jenkins core. This api needs to be called by plugin if and only if the agents are provisioned differently.

Implementation note: onComplete and onFailure are being called while holding the queue lock from NodeProvisioner, so the work is extracted to separate thread.

public void onComplete(NodeProvisioner.PlannedNode plannedNode,
 Node node)

Overrides:

onComplete in class CloudProvisioningListener

onComplete

@CheckForNull
public ProvisioningActivity onComplete(@NonNull
 ProvisioningActivity.Id id,
 @NonNull
 Node node)

Inform plugin provisioning has completed. This is only needed when provisioned outside NodeProvisioner.

The method should be called before the node is added to Jenkins.

onFailure

@Restricted(org.kohsuke.accmod.restrictions.DoNotUse.class)
public void onFailure(NodeProvisioner.PlannedNode plannedNode,
 Throwable t)

Overrides:

onFailure in class CloudProvisioningListener

onFailure

@CheckForNull
public ProvisioningActivity onFailure(@NonNull
 ProvisioningActivity.Id id,
 @NonNull
 Throwable throwable)

Inform plugin provisioning has failed. This is only needed when provisioned outside NodeProvisioner.

No node with id should be added added to jenkins.
