NAME

       varnishstat - Varnish Cache statistics

SYNOPSIS

       varnishstat [-1] [-x] [-j] [-f field_list] [-l] [-n varnish_name] [-V] [-w delay]

DESCRIPTION

       The varnishstat utility displays statistics from a running varnishd(1) instance.

       The following options are available:

       -1     Instead  of  presenting  of a continuously updated display, print the statistics to
              stdout.

       -f     A comma separated list of the fields to display.  If it starts with '^' it is  used
              as an exclusion list.

       -l     Lists the available fields to use with the -f option.

       -n     Specifies  the  name  of  the  varnishd  instance  to  get logs from.  If -n is not
              specified, the host name is used.

       -V     Display the version number and exit.

       -w delay
              Wait delay seconds between updates.  The default is 1. Can also be used with -1, -x
              or -j for repeated output.

       -x     Displays the result as XML.

       -j     Displays the result as JSON.

       The columns in the main display are, from left to right:

       1. Value

       2. Per-second average in the period since last update, or a period if the value can not be
          averaged

       3. Per-second average over process lifetime, or a period if the value can not be averaged

       4. Descriptive text

       When using the -1 option, the columns in the output are, from left to right:

       1. Symbolic entry name

       2. Value

       3. Per-second average over process lifetime, or a period if the value can not be averaged

       4. Descriptive text

       When using the -x option, the output is:

          <stat>
            <name>FIELD NAME</name>
            <value>FIELD VALUE</value>
            <description>FIELD DESCRIPTION</description>
          </stat>

       With -j the output format is:

          {
            "timestamp": "YYYY-MM-DDTHH:mm:SS",
            "client_conn": {
                "value": 0, "flag": "a",
                "description": "Client connections accepted"
            },
            "client_drop": {
                "value": 0, "flag": "a",
                "description": "Connection dropped, no sess/wrk"
            },
            "LCK.backend.creat": {
                "type": "LCK", "ident": "backend", "value": 1,
                "flag": "a", "description": "Created locks"
            },
            [..]
          }

       Timestamp is the time when the report was generated by varnishstat.

       Repeated output with -1, -x or -j will have a single empty line (\n) between each block of
       output.
