.TH JMOND 8 "Sep 09, 1999" "" "Linux System Administrator's Manual"
.SH NAME
jmond \- jMon distributed resource monitor daemon
.SH SYNOPSIS
.B jmond
[\c
.BI \-p \ port\fP\c
]
.br
.SH DESCRIPTION
\fBjmond\fP is the daemon part of the jMon Distributed Resource Monitor. The
\fBjmon\fP(1) client creates a TCP/IP connection to the \fBjmond\fP daemon
running on each of the hosts that are to be monitored. The daemon calculates
the resource usage from the \fB/proc\fP filesystem.
.SH OPTIONS
.TP
.BI \-f \ port\fP
This parameter specifies the \fBport\fP that the daemon should listen on. This
parameter is optional, with the default being port \fB7777\fP.
.SH DIAGNOSTICS
The daemon calculates the resource usage from \fB/proc/stat\fP (CPU info) and
\fB/proc/meminfo\fP (memory and swap info). In order to allow this process,
support for the virtual /proc filesystem MUST be compiled into the kernel and
it must be mounted.
.LP
For the sake of convenience, the \fBjmond\fP daemon forks to create a child,
killing the parent. This allows for easy daemon installation using, for
example, the SysVInit startup method. In order to further facilitate this
method, the daemon writes its process id to the file \fB/var/run/jmond.pid\fP.
