VARNISHNCSA(1)            BSD General Commands Manual           VARNISHNCSA(1)

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

SYNOPSIS
     varnishncsa [-a] [-b] [-C] [-c] [-D] [-d] [-I regex] [-i tag] [-n varnish_name]
                 [-P file] [-r file] [-V] [-w file] [-X regex] [-x tag]

DESCRIPTION
     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 pro-
                 cess entries which are written to the log after it starts.

     -I regex    Include log entries which match the specified regular expression.  If
                 neither -I nor -i is specified, all log entries are included.

     -i tag      Include log entries with the specified tag.  If neither -I nor -i is
                 specified, all log entries are included.

     -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.
