NAME

varnishlog - Display Varnish logs

SYNOPSIS

[-a ] [-b ] [-C ] [-c ] [-D ] [-d ] [-I regex ] [-i tag ] [-k keep ] [-n varnish_name ] [-o ] [-P file ] [-r file ] [-s num ] [-u ] [-V ] [-w file ] [-X regex ] [-x tag ] [tag regex ]

DESCRIPTION

The 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 backend server. If neither -b nor -c is specified, 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, acts as if they both were.
-D
Daemonize.
-d
Process old log entries on startup. Normally, 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.
-k num
Only show the first num log records.
-n
Specifies the name of the varnishd instance to get logs from. If -n is not specified, the host name is used.
-o
Group log entries by request ID. This has no effect when writing to a file using the -w option.
-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 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.

If the -o option was specified, an additional tag and regex may be specified to select only requests which generated a log entry with the given tag whose contents match the given regex
