Servlet header decorator

[Legacy User]

Just curious if anyone noticed a significant performance degradation on the client side when the http servlet header decorator is enabled in your Java Agent Profile or CEM.

Default is false.

# Servlet Header Decorator

# =======================================

# On/Off Switch

#

# ================

# If this Boolean value is set to true, it configures the agent to add

# additional performance monitoring information to HTTP response

# headers.  ServletHeaderDecorator attaches the GUID to each transaction

# and inserts the GUID into an HTTP header, x-wily-info

# This enables the correlation of transaction between Wily CEM and Wily Introscope

1. introscope.agent.decorator.enabled=true

We have been running the Servlet Decorator for three years and the additional header values of the x-wily* has not impacted performance to a point to be a leading issue/cause.

 

Hope this helps,
