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

NAME

       varnishlog - Display Varnish logs

SYNOPSIS

       varnishlog  [-a]  [-b] [-C] [-c] [-D] [-d] [-I regex] [-i tag] [-k keep] [-n varnish_name] [-o] [-O] [-m tag:regex ...] [-P file] [-r file]
       [-s num] [-u] [-V] [-w file] [-X regex] [-x tag]

DESCRIPTION

       The varnishlog utility reads and presents varnishd(1) shared memory logs.

       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, varnishlog 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, varnishlog acts as if they
	      both were.

       -D     Daemonize.

       -d     Process old log entries on startup.  Normally, varnishlog will only process 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.

       -k num Only show the first num log records.

       -m tag:regex only list transactions where tag matches regex. Multiple
	      -m options are AND-ed together.  Can not be combined with -O

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

       -o     Ignored for compatibility with earlier versions.

       -O     Do not group log entries by request ID.  Can not be combined with -m.

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

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

       -s num Skip the first num log records.

       -u     Unbuffered output.

       -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  var-
	      nishlog 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.
