Configures logging of individual cache.log messages.
cache_log_message id=<number> option...
cache_log_message ids=<number>-<number> option...
Most messages have _not_ been instrumented to support this directive
yet. For the list of instrumented messages and their IDs, please see
the doc/debug-messages.dox file.
Message ID corresponds to the message semantics rather than message
text or source code location. The ID is stable across Squid
instances and versions. Substantial changes in message semantics
result in a new ID assignment. To reduce the danger of suppressing
an important log message, the old IDs of removed (or substantially
changed) messages are never reused.
If more than one cache_log_message directive refers to the same
message ID, the last directive wins.
Use ids=min-max syntax to apply the same message configuration to an
inclusive range of message IDs. An ID range with N values has
exactly the same effect as typing N cache_log_message lines.
At least one option is required. Supported options are:
level=<number>: The logging level to use for the message. Squid
command line options (-s and -d) as well as the debug_options
directive control which levels go to syslog, stderr, and/or
cache.log. In most environments, using level=2 or higher stops
Squid from logging the message anywhere. By default, the
hard-coded message-specific level is used.
limit=<number>: After logging the specified number of messages at
the configured (or default) debugging level DL, start using
level 3 (for DL 0 and 1) or 8 (for higher DL values). Usually,
level-3+ messages are not logged anywhere so this option can
often be used to effectively suppress the message. Each SMP
Squid process gets the same limit.
