Fabric Watch notification types
Enabling e-mail alerts for the Changed threshold state in several areas can quickly result in a
significant amount of e-mail. Fabric Watch discards e-mail alerts when more than 100 are
generated within a minute, which minimizes memory use.

SNMP traps

In environments where you have a high number of messages coming from a variety of switches, you
might want to receive them in a single location and view them using a graphical user interface
(GUI). In this type of scenario, the Simple Network Management Protocol (SNMP) notifications
might be the most efficient notification method. You can avoid having to log in to each switch
individually as you would have to do for error log notifications.
SNMP performs an operation called a trap that notifies a management station using SNMP when
events occur. Log entries can also trigger SNMP traps if the SNMP agent is configured. When the
SNMP agent is configured to a specific error message level, error messages at that level trigger
SNMP traps.
An SNMP trap forwards the following information to an SNMP management station:
•
•
•
•
•
•
You must configure the software to receive trap information from the network device. You must also
configure the SNMP agent on the switch to send the trap to the management station. You can
configure SNMP notifications using the snmpConfig command and you can configure notifications
using Fabric Watch.
For information on configuring the SNMP agent using the snmpConfig command, see the Fabric OS
Command Reference.

RASlog (switch event)

Following an event, Fabric Watch adds an entry to the internal event log for an individual switch.
RASlog stores event information but does not actively send alerts. Use the errShow command to
view the RASlog.

When a counter is in the "in-between" state, Fabric Watch sends an informational SNMP trap.

boundaries and above high, below high, above low, and below low thresholds.
When a counter is above the high threshold or below the low threshold, Fabric Watch sends a
warning SNMP trap except for the power supply area of the environment (ENV), CPU, and
Memory classes. The severity of a Fabric Watch SNMP trap for CPU and memory will always be
informational.
