The PingAccess agent for Apache writes its information to the standard Apache error
log, defined in the Apache configuration with the ErrorLog configuration
directive.
All information logged by the agent is prefaced with the string
[paa]. Agent monitoring and performance information is prefaced
with the string [paa-monitoring], and contains information about
how long the agent took to fill a cache request and how long the total policy
decision took.
The LogLevel used by the agent module is taken from the top-level httpd.conf configuration.
