All Implemented Interfaces:

GuiceyLifecycleListener

public class StartupTimeDiagnostic
extends UniqueGuiceyLifecycleListener

Startup time report. Timers could count only time AFTER guice bundle creation (with guice bundle itself).

Report hacks dropwizard bundles and managed objects to track all bundles time. Note that it is impossible to track init time of bundles registered before guice bundle.

Entire application startup time (measured since guice bundle creation) is split into 3 chunks:

• init phase - all dropwizard bundle init methods called
• run phase - all dropwizard bundles run methods called (+ time of Configuration and Environment creation); also includes application init method
• web phase - everything after last dropwizard bundle run (including application run method)

To avoid confusion with server startup time - jvm start time is also shown (time from jvm start and before guice bundle creation).

Method Detail

beforeInit

protected void beforeInit(BeforeInitEvent event)

Description copied from class: GuiceyLifecycleAdapter

Special meta event, called before all GuiceBundle configuration phase logic. Bootstrap object is available, but dropwizard bundles (registered through guicey) are not yet registered (note that GuiceBundle is not yet added to bootstrap also because dropwizard calls bundle initialization before registering bundle (and so all dropwizard bundles, registered by guicey, will run before GuiceBundle run).

Overrides:

beforeInit in class GuiceyLifecycleAdapter

Parameters:

event - event object

See Also:

GuiceyLifecycle.BeforeInit

bundlesInitialized

protected void bundlesInitialized(BundlesInitializedEvent event)

Description copied from class: GuiceyLifecycleAdapter

Called after bundles initialization. Note that bundles could register other bundles and so resulted list of installed bundles could be bigger (than in resolution event).

Overrides:

bundlesInitialized in class GuiceyLifecycleAdapter

Parameters:

event - event object

See Also:

GuiceyLifecycle.BundlesInitialized

beforeRun

protected void beforeRun(BeforeRunEvent event)

Description copied from class: GuiceyLifecycleAdapter

Meta event. Called just before guice bundle processing in run phase.

Overrides:

beforeRun in class GuiceyLifecycleAdapter

Parameters:

event - event object

See Also:

GuiceyLifecycle.BeforeRun

applicationRun

protected void applicationRun(ApplicationRunEvent event)

Description copied from class: GuiceyLifecycleAdapter

Called after GuiceBundle.run(io.dropwizard.core.Configuration, io.dropwizard.core.setup.Environment) when guicey context is started, extensions installed (but not hk extensions, because neither jersey nor jetty isn't start yet).

Overrides:

applicationRun in class GuiceyLifecycleAdapter

Parameters:

event - event object

See Also:

GuiceyLifecycle.ApplicationRun
