Time base configuration
The time base specifies the time interval between two samples to be compared. The
fwSetToCustom command allows you to switch from default to custom settings. Valid intervals are
day, hour, or minute. Refer to “Setting Fabric Watch custom and default values” on page 30 for
more information.
Threshold and action configuration
Before you begin to configure thresholds, decide if you want to have different levels of alerts for
E_Ports, FOP_Ports, and FCU_Ports, and configure the ports individually. Always set up thresholds
one fabric at a time and test the configuration before you apply the threshold configuration to more
switches or fabrics.
NOTE
You cannot configure different thresholds for server and storage ports, because threshold
configuration is an area-wide setting and cannot be configured on an element (port).
Monitoring
Do you want to monitor all class areas, or implement the monitoring in incremental stages? If you
monitor class areas incrementally, you should configure Fabric Watch to monitor the classes in the
following order:
1. Monitor Fabric class areas using the thConfig command.
Refer to Chapter 6, “Fabric, Security, SFP, and Performance Monitoring,” for details.
2. Monitor Port class areas using the portThConfig command.
Refer to Chapter 7, “Port Monitoring,” for details.
3. Monitor FRU class areas using the fwFruCfg command.
Refer to Chapter 8, “System Monitoring,” for details.
NOTE
For each class area, there are setting guidelines and recommendations for whether you should
leave the setting at the default or change the settings. If a change is recommended, the reason for
the change and the suggested settings are provided in each of the configuration chapters. The
default settings are listed in these chapters as well.
Post-processing of messages
After you have configured thresholds and alerts, determine to where the messages will be sent.
Then, monitor the messages frequently and take the appropriate actions.
Class, area, and element hierarchy
Fabric elements and events are organized in a hierarchy by class, area, and element. There is a
class, area, and element associated with every monitored behavior. Classes are the highest level in
the system, subdivided into one or more areas. Areas contain one or more elements.
