Event log file formats

Content Gateway supports the following log file formats:

  • Standard formats, such as Squid or Netscape (see Using standard formats)
  • Content Gateway custom format (see Custom format)

In addition to the standard and custom log file format, you must choose whether to save log files in binary or ASCII. See Choosing binary or ASCII.

Important: Event log files consume a large amount of disk space. Creating log entries in multiple formats at the same time can consume disk resources very quickly and affect proxy performance.

When IPv6 is enabled, Event log entries are normalized to IPv6 format.

For example, “10.10.41.200” is logged as “::ffff:10.10.41.200”.

To filter on a client at “10.10.41.200” in a custom log, use:

<LogFilter> 
<Name = "IPv6_Test_Machine"/>
<Condition =
"chi MATCH ::ffff:10.10.41.200"/>
<Action = "ACCEPT"/>
</LogFilter>
