varnishscoreboard

Display Varnish tasks

Manual section:1

SYNOPSIS

varnishscoreboard [-h] [-n <dir>] [-t <seconds|off>] [-V]

DESCRIPTION

The varnishscoreboard utility displays scheduled tasks managed by the thread pools workers in the varnishd cache process. It can report ongoing, waiting and queued tasks with some information about them. In addition to tasks, it accounts for the number of idle workers, threads without a task to run.

In order to keep track of tasks, thread_pool_track needs to be enabled. Only a limited amount of tasks can be tracked and the amount of memory allocated to tracking is controlled by the vst_space parameter.

OPTIONS

The following options are available:

-h Print program usage and exit
-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.
-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.
-V Print version information and exit.
--optstring Print the optstring parameter to getopt(3) to help writing wrapper scripts.
