NAME
varnishhist - Varnish request histogram
SYNOPSIS
varnishhist [-b] [-C] [-c] [-d] [-I regex] [-i tag] [-n varnish_name]
[-r file] [-V] [-w delay] [-X regex] [-x tag]
DESCRIPTION
The varnishhist utility reads varnishd(1) shared memory logs and presents
a continuously updated histogram showing the distribution of the last N
requests by their processing. The value of N and the vertical scale are
displayed in the top left corner. The horizontal scale is logarithmic.
Hits are marked with a pipe character ("|"), and misses are marked with a
hash character ("#").
The following options are available:
-b Include log entries which result from communication with a
backend server. If neither -b nor -c is specified,
varnishhist 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, varnishhist acts
as if they both were.
-d Process old log entries on startup. Normally, varnishhist
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.
-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.
-w delay Wait at least delay seconds between each update. The default
is 1. file instead of displaying them. The file will be
overwritten unless the -a option was specified.
-X regex Exclude log entries which match the specified regular
expression.
-x tag Exclude log entries with the specified tag.
