VARNISHTOP(1)             BSD General Commands Manual            VARNISHTOP(1)

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 continu-
     ously updated list of the most commonly occurring log entries.  With suitable filter-
     ing 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 pro-
                 cess 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.

     -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
