SYNOPSISvarnishlog [-a] [-b] [-B] [-c] [-C] [-d] [-D] [-g <ses‐
sion|request|vxid|raw>] [-h] [-i taglist] [-I <[taglist:]regex>] [-L
limit] [-n name] [-N filename] [-P file] [-q query] [-r filename] [-T
seconds] [-v] [-V] [-w filename] [-x taglist] [-X <[taglist:]regex>]
<query expression>
OPTIONS
The following options are available:
-a When writing output to a file, append to it rather than over‐
write it.
-b Only display transactions and log records coming from backend
communication.
-B Output binary data suitable for reading with -r.
-c Only display transactions and log records coming from client
communication.
-C Do all regular expression and string matching caseless.
-d Start processing log records at the head of the log instead of
the tail.
-D Daemonize.
-g <session|request|vxid|raw>
The grouping of the log records. The default is to group by
vxid.
-h Print program usage and exit
-i taglist
Include log records of these tags in output. Taglist is a
comma-separated list of tag globs. Multiple -i options may be
given.
If a tag include option is the first of any tag selection
options, all tags are first marked excluded.
-I <[taglist:]regex>
Include by regex matching. Output only records matching taglist
and regular expression. Applies to any tag if taglist is absent.
If a tag include option is the first of any tag selection
options, all tags are first marked excluded.
-L limit
Sets the upper limit of incomplete transactions kept before the
oldest transaction is force completed. A warning record is syn‐
thesized when this happens. This setting keeps an upper bound on
the memory usage of running queries. Defaults to 1000 transac‐
tions.
-n name
Specify the name of the varnishd instance to get logs from. If
-n is not specified, the host name is used.
-N filename
Specify the filename of a stale VSM instance. When using this
option the abandonment checking is disabled.
-P file
Write the process' PID to the specified file.
-q query
Specifies the VSL query to use.
-r filename
Read log in binary file format from this file.
-T seconds
Sets the transaction timeout in seconds. This defines the maxi‐
mum number of seconds elapsed between a Begin tag and the End
tag. If the timeout expires, a warning record is synthesized and
the transaction is force completed. Defaults to 120 seconds.
-v Use verbose output on record set printing, giving the VXID on
every log line. Without this option, the VXID will only be given
on the header of that transaction.
-V Print version information and exit.
-w filename
Redirect output to file. The file will be overwritten unless the
-a option was specified. If the application receives a SIGHUP
the file will be reopened allowing the old one to be rotated
away.
-x taglist
Exclude log records of these tags in output. Taglist is a
comma-separated list of tag globs. Multiple -x options may be
given.
-X <[taglist:]regex>
Exclude by regex matching. Do not output records matching
taglist and regular expression. Applies to any tag if taglist is
absent.
-k num Only show the first num log transactions (or log records in -g
raw mode)
XXX: Not yet implemented
-s num Skip the first num log transactions (or log records if in -g raw
mode)
XXX: Not yet implemented
SIGNALS
· SIGHUP
Rotate the log file (see -w option)
· SIGUSR1
Flush any outstanding transactions
