VARNISHNCSA(1) BSD General Commands Manual VARNISHNCSA(1)
NAME
varnishncsa - Display Varnish logs in Apache / NCSA combined log format
SYNOPSIS
varnishncsa [-a] [-b] [-C] [-c] [-D] [-d] [-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 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.
-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 expression.
-x tag Exclude log entries with the specified tag.
