man jmond (Administration système) - jMon distributed resource monitor daemon
NAME
jmond - jMon distributed resource monitor daemon
SYNOPSIS
jmond
[c
-p portc
]
DESCRIPTION
jmond is the daemon part of the jMon Distributed Resource Monitor. The jmon(1) client creates a TCP/IP connection to the jmond daemon running on each of the hosts that are to be monitored. The daemon calculates the resource usage from the /proc filesystem.
OPTIONS
- -p port
- This parameter specifies the port that the daemon should listen on. This parameter is optional, with the default being port 7777.
DIAGNOSTICS
The daemon calculates the resource usage from /proc/stat (CPU info) and /proc/meminfo (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.
For the sake of convenience, the jmond 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 /var/run/jmond.pid.
