NAME

       varnishtop - Varnish log entry ranking

SYNOPSIS

       varnishtop  [-1]  [-b] [-C] [-c] [-d] [-f] [-I regex] [-i tag] [-n varnish_name] [-r file]
       [-V] [-X regex] [-x tag]

DESCRIPTION

       The varnishtop utility reads varnishd(1) shared memory logs and  presents  a  continuously
       updated  list  of  the most commonly occurring log entries.  With suitable filtering using
       the -I, -i, -X and -x options, it can be used to display a ranking of requested documents,
       clients, user agents, or any other information which is recorded in the log.

       The following options are available:

       -1     Instead  of presenting of a continuously updated display, print the statistics once
              and exit. Implies -d.

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

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

       -f     Sort  and  group  only  on  the first field of each log entry.  This is useful when
              displaying e.g. stataddr entries, where the first field is the client IP address.

       -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.

       -p period
              Specifies the number of seconds to measure over, the default  is  60  seconds.  The
              first  number  in  the  list  is the average number of requests seen over this time
              period.

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

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

       -V     Display the version number and exit.

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

       -x tag Exclude log entries with the specified tag.

EXAMPLES

       The  following  example  displays  a  continuously  updated  list  of  the most frequently
       requested URLs::

       varnishtop -i RxURL

       The following example displays a continuously updated list of the most commonly used  user
       agents::

       varnishtop -i RxHeader -C -I ^User-Agent
