Here is an example output:

.PP
The result is in the following order:
.sp
.if n \{\
.RS 4
.\}
.nf
    The first output line describes the watchdog cluster information:

    1\&. Total watchdog nodes in the cluster
    2\&. Total watchdog nodes in the cluster with active membership
    3\&. Local node\*(Aqs escalation status
    4\&. Leader node name
    5\&. Leader node host
   
.fi
.if n \{\
.RE
.\}
.sp

.sp
.if n \{\
.RS 4
.\}
.nf
    Next is the list of watchdog nodes:

    1\&. node name
    2\&. hostname
    3\&. pgpool port
    4\&. watchdog port
    5\&. current node state
    6\&. current node state name
    7\&. current cluster membership status
    8\&. current cluster membership status name
   
.fi
.if n \{\

.PP
The
\fB\-\-verbose\fR
option can help understand the output\&. For example:
.sp
.if n \{\
