SYNOPSIS

[-b ] [-C ] [-c ] [-d ] [-I regex ] [-i tag ] [-n varnish_name ] [-r file ] [-V ] [-w delay ] [-X regex ] [-x tag ]

DESCRIPTION

The 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, 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, acts as if they both were.

-d

Process old log entries on startup. Normally, 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.
