VARNISHNCSA(1)

NAME

varnishncsa -- Display Varnish logs in Apache / NCSA combined log format

SYNOPSIS

varnishncsa [-a] [-b] [-C] [-c] [-D] [-d] [-f] [-I regex] [-i tag]
            [-n varnish_name] [-P file] [-r file] [-V] [-w file]
            [-X regex] [-x tag]

DESCRIPTION

The varnishncsa utility reads varnishd(1) shared memory logs and presents them in the Apache / NCSA "combined" log format.

The following options are available:

-a When writing to a file, append to it rather than overwrite

it.

-b Include log entries which result from communication with a

backend server. If neither -b nor -c is specified,
varnishncsa 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, varnishncsa acts as if they both were.

-D Daemonize.

-d Process old log entries on startup. Normally, varnishncsa

will only process entries which are written to the log after it starts.

-f Prefer the X-Forwarded-For HTTP header over client.ip in the

log output.

-I regex Include log entries which match the specified regular expres

sion. 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.

-P file Write the process's PID to the specified file.

-r file Read log entries from file instead of shared memory.

-V Display the version number and exit.

-w file Write log entries to file instead of displaying them. The

file will be overwritten unless the -a option was specified.

If varnishncsa receives a SIGHUP while writing to a file, it will reopen the file, allowing the old one to be rotated
away.

-X regex Exclude log entries which match the specified regular expres

sion.

-x tag Exclude log entries with the specified tag.
