.SH NAME
.LP
\fBwork_queue_status\fP - display status of currently running Work Queue applications.

.SH SYNOPSIS
.LP

.SH DESCRIPTION
.LP

\fBwork_queue_status\fP displays the status of currently running Work Queue applications.
When run with no options, it queries the global catalog server to list the currently running
Work Queue masters.  When given an address and a port, it queries a master directly to obtain
more detailed information about tasks and workers.

Hostname and port number of the application.
.IP \(bu 4
Number of waiting tasks.
.IP \(bu 4
Number of completed tasks.
.IP \(bu 4
Number of connected workers.
.IP \(bu 4
Number of tasks currently being executed.
.IP \(bu 4
Timestamp of when there was last communication with the application.

Without arguments, \FCwork_queue_status\FT shows a summary of all of the
projects currently reporting to the default catalog server. Waiting, running,
and complete columns refer to number of tasks:

The \FC-A\FT option shows a summary of the resources observed per task
category.

.fam C

.fi
.hy
.fam
.P

With the -A option:

.IP \(bu 4
Running and waiting correspond to number of tasks in the category.
.IP \(bu 4
Fit-workers shows the number of connected workers able to run the largest task in the category.
.IP \(bu 4
max-cores, max-memory, and max-disk show the corresponding largest value in the category.


The value may have the following prefixes:

.IP \(bu 4
No prefix. The maximum value was manually specified.
.IP \(bu 4
~ All the task have run with at most this quantity of resources.
.IP \(bu 4
> There is at least one task that has used more than this quantity of resources, but the maximum remains unknown.



Finally, the \FC-l\FT option shows statistics of the queue in a JSON object:

.fam C
.nf
.nh
.IP "" 8
$ work_queue_status -l cclws16.cse.nd.edu 9001
{"categories":[{"max_disk":"3500","max_memory":"1024","max_cores":"1",...
