Interface GridTracingSpi

All Superinterfaces:

GridSpi

All Known Implementing Classes:

GridJxinsightTracingSpi

@Apache20LicenseCompatible
public interface GridTracingSpi
extends GridSpi

SPI provides pluggable tracing facility for GridGain. System runtime intercepts main implementation methods and notifies this SPI. Implementation of this SPI should provide any necessary processing of interception callbacks like collecting statistics, searching for patterns, passing further to external monitoring console, etc.

GridGain comes with one default implementation:

• GridJxinsightTracingSpi - receives method call notifications from local grid and informs JXInsight Tracer.

               String methodName,
               Object[] args,
               @Nullable
               Object res,
               Throwable e)

This callback is called right after target method interception.

Parameters:

cls - Callee class.

methodName - Callee method name.

args - Callee method parameters.

res - Call result. Might be null if call returned null or if exception happened.
