Changing the monitor threshold
A changing monitor threshold generates events whenever a counter value changes,
regardless of the type of change. This type of threshold is usually used to indicate
state changes, such as zoning changes. Because change monitor thresholds
include no boundaries, no illustration is provided.
Installing Fabric Watch
The installation of Fabric Watch involves the installation of a license on each switch
where you want to enable Fabric Watch. A license may have been installed in the
switch at the factory. If not, contact your IBM sales representative to obtain a
license key.
Fabric Watch requires a 2109 switch with Fabric OS version 2.2 or later. A Fabric
Watch license can be installed either through Telnet commands or through the IBM
StorWatch Specialist.
Installing Fabric Watch through Telnet
1. Log onto the switch by Telnet (see the User’s Guide provided with the hardware
for details), using an account that has administrative privileges.
2. To determine whether a Fabric Watch license is already installed on the switch,
type
licenseShow
on the Telnet command line.
