.SH NOTES
If this program is called as crm_mon.cgi, \fB\-\-output\-as\fR=\fI\,html\/\fR \fB\-\-html\-cgi\fR will
automatically be added to the command line arguments.
.SH TIME SPECIFICATION
The TIMESPEC in any command line option can be specified in many different
formats.  It can be just an integer number of seconds, a number plus units
(ms/msec/us/usec/s/sec/m/min/h/hr), or an ISO 8601 period specification.
.SH OUTPUT CONTROL
By default, a certain list of sections are written to the output destination.
The default varies based on the output format \- XML includes everything, while
other output formats will display less.  This list can be modified with the
\fB\-\-include\fR and \fB\-\-exclude\fR command line options.  Each option may be given multiple
times on the command line, and each can give a comma\-separated list of sections.
The options are applied to the default set, from left to right as seen on the
command line.  For a list of valid sections, pass \fB\-\-include\fR=\fI\,list\/\fR or \fB\-\-exclude\fR=\fI\,list\/\fR.
.SH EXAMPLES
Display the cluster status on the console with updates as they occur:
.IP
crm_mon
.PP
Display the cluster status on the console just once then exit:
.IP
crm_mon \-1
.PP
Display your cluster status, group resources by node, and include inactive resources in the list:
.IP
crm_mon \-\-group\-by\-node \-\-inactive
.PP
Start crm_mon as a background daemon and have it write the cluster status to an HTML file:
.IP
crm_mon \-\-daemonize \-\-output\-as html \-\-output\-to /path/to/docroot/filename.html
.PP
Start crm_mon and export the current cluster status as XML to stdout, then exit:
.IP
crm_mon \-\-output\-as xml
