How to suppress 404 page not found error?

Environment:
APM 10.x
Answer:

 You can uncomment and use this property in the IntroscopeAgent.profile to ignore the 404 errors: 

# The following series of properties lets you specify error messages
# to ignore. For errors with messages matching these filters,
# error snapshots and error metrics will not be generated or sent.  
# You may specify as many as you like (using .0, .1, .2 ...). You may use wildcards (*).  
# The following are examples only.
# Changes to this property take effect immediately and do not require the managed application to be restarted.
#introscope.agent.errorsnapshots.ignore.0=*com.company.HarmlessException*
#introscope.agent.errorsnapshots.ignore.1=*HTTP Error Code: 404*
