varnishtop - Varnish log entry ranking
varnishtop [-1] [-b] [-C] [-c] [-d] [-f] [-I regex] [-i tag] [-n varnish_name] [-r file] [-V] [-X regex] [-x tag]
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.
