Alert configuration
When Fabric Watch is improperly configured, a large number of error messages can be sent over a
short period of time, making it difficult to find those messages that are actually meaningful. If this
happens, there are a few simple ways to improve the configuration.
When large numbers of unimportant messages are received, examining the source can identify those
classes that need to be reconfigured. To reduce the number of unimportant messages, consider the
following reconfiguration options:
• Recheck the threshold settings. If the current thresholds are not realistic for the class and area,
messages may be sent frequently without need. For example, a high threshold for temperature
monitoring set to less than room temperature is probably incorrectly configured. These messages
could cause other important messages to be missed.
• Examine the notification settings. If you are not interested in receiving messages under certain
conditions, ensure that the notification setting for that event is set to zero.
Brocade recommends using either SNMP trap alerting to your system management console or event
log entry in conjunction with syslog forwarding configured on your switches.
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 43 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 Fabric, Security, SFP, and Performance Monitoring on page 47 for details.
2. Monitor Port class areas using the portThConfig command.
Refer to Port Monitoring on page 65 for details.
3. Monitor FRU class areas using the fwFruCfg command.
Refer to System Monitoring on page 87 for details.
