VARNISHHIST(1) BSD General Commands Manual VARNISHHIST(1)
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 continu-
ously updated histogram showing the distribution of the last N requests by their pro-
cessing. 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 pro-
cess 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.
