NAME

       varnishlog - Display Varnish logs

SYNOPSIS

       varnishlog  [-a]  [-A]  [-b] [-c] [-C] [-d] [-D] [-E] [-g <session|request|vxid|raw>] [-h]
       [-i <taglist>] [-I <[taglist:]regex>] [-k <num>] [-L <limit>] [-n <dir>] [-P  <file>]  [-Q
       <file>]  [-q  <query>]  [-r  <filename>]  [-R  <limit[/duration]>]  [-t <seconds|off>] [-T
       <seconds>] [-u] [-v] [-V] [-w <filename>] [-x <taglist>] [-X <[taglist:]regex>]

OPTIONS

       The following options are available:

       -a     When writing output to a file  with  the  -w  option,  append  to  it  rather  than
              overwrite it. This option has no effect without the -w option.

       -A     When writing output to a file with the -w option, output data in ascii format. This
              option has no effect without the -w option.

       -b     Only display transactions and log records coming from backend communication.

       -c     Only display transactions and log records coming from client communication.

       -C     Do all regular expression and string matching caseless.

       -d     Process log records at the head of the log and exit.

       -D     Daemonize.

       -E     Display ESI transactions and other client transactions.

       -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. 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.

       -k <num>
              Process this number of matching log transactions before exiting.

       -L <limit>
              Sets  the upper limit of incomplete transactions kept before the oldest transaction
              is force completed. A warning record is synthesized when this happens. This setting
              keeps  an  upper  bound  on  the  memory usage of running queries. Defaults to 1000
              transactions.

       -n <dir>
              Specify the varnishd working directory (also known as instance name)  to  get  logs
              from. If -n is not specified, the host name is used.

       -P <file>
              Write the process' PID to the specified file.

       -Q <file>
              Specifies  the file containing the VSL query to use. When multiple -Q or -q options
              are specified, all queries are considered as if  the  'or'  operator  was  used  to
              combine them.

       -q <query>
              Specifies  the  VSL query to use. When multiple -q or -Q options are specified, all
              queries are considered as if the 'or' operator was used to combine them.

       -r <filename>
              Read log in binary file format from  this  file.  The  file  can  be  created  with
              varnishlog  -w  filename.  If  the  filename  is -, logs are read from the standard
              input. and cannot work as a daemon.

       -R <limit[/duration]>
              Restrict the output to the specified limit. Transactions exceeding the  limit  will
              be  suppressed.  The limit is specified as the maximum number of transactions (with
              respect to the chosen grouping method) and an optional time period. If no  duration
              is specified, a default of s is used. The duration field can be formatted as in VCL
              (e.g. -R 10/2m) or as a simple time period without the prefix (e.g. -R  5/m).  When
              in  -g  raw grouping mode, this setting can not be used alongside -i, -I, -x or -X,
              and we advise using -q instead.

       -t <seconds|off>
              Timeout before returning error on initial VSM connection. If set the VSM connection
              is  retried  every  0.5  seconds  for  this many seconds. If zero the connection is
              attempted only once and will fail immediately if unsuccessful. If set to "off", the
              connection  will  not fail, allowing the utility to start and wait indefinetely for
              the Varnish instance to appear.  Defaults to 5 seconds.

       -T <seconds>
              Sets the transaction timeout in seconds. This defines the maximum 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.

       -u     When writing output to a file with the -w option, output data is not buffered. This
              option has no effect without the -w option.

       -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 in daemon mode  the  file  will  be
              reopened  allowing  the  old  one  to be rotated away. The file can then be read by
              varnishlog and other tools with the -r option, unless the -A option was  specified.
              This  option  is  required  when  running  in  daemon  mode.  If the filename is -,
              varnishlog writes to the standard output and cannot work as a daemon.

       -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. Multiple  -X  options  may  be
              given.

       --optstring
              Print the optstring parameter to getopt(3) to help writing wrapper scripts.

SIGNALS

       • SIGHUP

         Rotate  the  log  file (see -w option) in daemon mode, abort the loop and die gracefully
         when running in the foreground.

       • SIGUSR1

         Flush any outstanding transactions

HISTORY

       The  varnishlog  utility  was  developed  by  Poul-Henning  Kamp  <phk@phk.freebsd.dk>  in

       written by Dag-Erling Smørgrav, and later updated by Per Buer and Martin Blix Grydeland.
