VARNISHTOP(1)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 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
