3.1.2 Matrix Server Administration Guide

Chapter 13: Configure Device Monitors 179

Timeout and Frequency: These fields are set to the default values for the

type of device you have selected. Change them as needed.

The other monitor parameters are dependent on the type of monitor that

you are creating.

•

DISK monitor. At the “Monitor partition” prompt, specify a partition

on the disk. The monitor will periodically attempt to read the first

block of this partition to determine whether the disk is operating

normally. Type the full partition name such as /dev/sda1.

•

CUSTOM monitor. At the “User probe script” prompt, specify the

pathname to the probe script to be used with the monitor. See

“Custom Scripts” on page 209 for information about writing probe

scripts.

•

SHARED_FILESYSTEM monitor. At the “Filesystem” prompt, select the

filesystem that is to be monitored. The “Filename” parameter is

optional. Enter the name of a file that the monitor probe should open

and attempt to read to determine the health of the filesystem. The

filename should be relative to the mount point of the filesystem. When

the filesystem is mounted, the mountpath will be prepended to the

filename to determine the complete filename path that should be

probed.

If you do not enter a filename, Matrix Server will create a file that will

be used by the monitor probe. The file will be named

MxS/<serverIP>/<monitor_name>, where <serverIP> is the dotted

decimal IP address of the hostname for the server, and <monitor_name>

is the name assigned to the

SHARED_FILESYSTEM device monitor.

The following example shows a

monitor created on the server r18.
