       varnishncsa - Display Varnish logs in Apache / NCSA combined log format


       varnishncsa  [-a]  [-b]  [-C]  [-c]  [-D]  [-d]  [-f]  [-F format] [-I regex] [-i tag] [-n
       varnish_name] [-m tag:regex ...] [-P file] [-r file] [-V] [-w file] [-X regex] [-x tag]


       The varnishncsa utility reads varnishd(1) shared memory logs  and  presents  them  in  the
       Apache / NCSA "combined" log format.

       The following options are available:

       -a     When writing to a file, append to it rather than overwrite it.

       -b     Include  log  entries  which  result  from communication with a backend server.  If
              neither -b nor -c is specified, varnishncsa acts as if they both were.

       -C     Ignore case when matching regular expressions.

       -c     Include log entries which result from communication with a client.  If  neither  -b
              nor -c is specified, varnishncsa acts as if they both were.

       -D     Daemonize.

       -d     Process  old  log  entries  on  startup.   Normally,  varnishncsa will only process
              entries which are written to the log after it starts.

       -f     Prefer the X-Forwarded-For HTTP header over client.ip in the log output.

       -F format
              Specify the log format used. If no format is specified the default  log  format  is
              used. Currently it is:

              %h %l %u %t "%r" %s %b "%{Referer}i" "%{User-agent}i"

              Supported formatters are:

                 %b     Size of response in bytes, excluding HTTP headers.  In CLF format, i.e. a
                        '-' rather than a 0 when no bytes are sent.

                 %H     The request protocol. Defaults to HTTP/1.0 if not known.

                 %h     Remote host. Defaults to '-' if not known.   Defaults  to  for
                        backend requests.

                 %{X}i  The contents of request header line X.

                 %l     Remote logname (always '-')

                 %m     Request method. Defaults to '-' if not known.

                 %q     The query string, if no query string exists, an empty string.

                 %{X}o  The contents of response header line X.

                 %r     The  first  line of the request. Synthesized from other fields, so it may
                        not be the request verbatim.

                 %s     Status sent to the client

                 %t     Time when the request was received, in HTTP date/time format.

                 %U     The request URL without any query string. Defaults to '-' if not known.

                 %u     Remote user from auth

                 %{X}x  Extended variables.  Supported variables are:

                                   Time to the first byte from the backend arrived

                                   Whether the request was a cache hit or miss. Pipe and pass are
                                   considered misses.

                                   How the request was handled, whether it was a cache hit, miss,
                                   pass, pipe or error.

       -m tag:regex only list records where tag matches regex. Multiple
              -m options are AND-ed together.

       -n     Specifies the name of the varnishd instance  to  get  logs  from.   If  -n  is  not
              specified, the host name is used.

       -P file
              Write the process's PID to the specified file.

       -r file
              Read log entries from file instead of shared memory.

       -V     Display the version number and exit.

       -w file
              Write log entries to file instead of displaying them.  The file will be overwritten
              unless the -a option was specified.

              If varnishncsa receives a SIGHUP while writing to a file, it will reopen the  file,
              allowing the old one to be rotated away.

       -X regex
              Exclude log entries which match the specified regular expression.

       -x tag Exclude log entries with the specified tag.

       If  the  -o  option  was specified, a tag and a regex argument must be given.  varnishncsa
       will then only log for request groups which include that tag and  the  regular  expression
       matches on that tag.
