varnishhist: Varnish request histogram

NAME
varnishhist - Varnish request histogram
SYNOPSIS
varnishhist [-b] [-C] [-c] [-d] [-I regex] [-i tag] [-m tag:regex ...] [-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 show- ing the distribution of the last N requests by their processing. The value of N and the vertical scale are dis- played 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. -m tag:regex only count transactions where tag matches regex. Multiple -m options are AND-ed together. -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.
