VARNISHLOG(1)VARNISHLOG(1)NAMEvarnishlog - Display Varnish logs
SYNOPSISvarnishlog [-a] [-b] [-C] [-c] [-D] [-d] [-I regex] [-i tag] [-k keep]
[-n varnish_name] [-o] [-O] [-m tag:regex ...] [-P file] [-r file] [-s
num] [-u] [-V] [-w file] [-X regex] [-x tag]
DESCRIPTION
The varnishlog utility reads and presents varnishd(1) shared memory
logs.
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 back‐
end server. If neither -b nor -c is specified, varnishlog 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, varnishlog acts as
if they both were.
-D Daemonize.
-d Process old log entries on startup. Normally, varnishlog will
only process entries which are written to the log after it
starts.
-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.
-k num Only show the first num log records.
-m tag:regex only list transactions where tag matches regex. Multiple
-m options are AND-ed together. Can not be combined with -O
-n Specifies the name of the varnishd instance to get logs from.
If -n is not specified, the host name is used.
-o Ignored for compatibility with earlier versions.
-O Do not group log entries by request ID. Can not be combined
with -m.
-P file
Write the process's PID to the specified file.
-r file
Read log entries from file instead of shared memory.
-s num Skip the first num log records.
-u Unbuffered output.
-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 var‐
nishlog 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.
