Port persistence

In the case of port monitoring, there is an additional factor to consider. The data collected in port

monitoring can vary a lot over short time periods. Therefore, the port can become a source of frequent

event messages (the data can exceed the threshold range and return to a value within the threshold range).

Fabric Watch uses port persistence for a port event that requires the transition of the port into a marginal

status. Fabric Watch does not record any event until the event persists for a length of time equal to the port

persistence time. If the port returns to normal boundaries before the port persistence time elapses, Fabric

Watch does not record any event.

The port persistence time is measured in seconds, and can be configured. Configuring the port persistence

time to zero disables this feature.

Notification methods

There are five notification methods available through Fabric Watch, but not all notification methods can be

applied to all of the classes. Valid notification methods are represented through the valid alarm matrix.

Fabric Watch provides the following notification methods:

•

”

Switch event (error) log entry

” on page 25

•

”

SNMP trap

” on page 25

•

”

RAPITrap

” on page 26

•

”

Port log lock

” on page 26

•

”

Email alert

” on page 26

To enable event settings, you must set the associated attribute to a nonzero value between one and thirty

one. The exact value you specify determines which event notification method Fabric Watch uses if the event

setting criteria is met.

For details about valid notification methods in the alarm matrix, see ”

Assigning notification methods

” on

page 26.

Switch event (error) log entry

The switch event (error) log holds up to 1024 entries. This error log stores event information but does not

actively send alerts. Use the

ErrShow

command to view the log.

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, then error messages at that level triggers SNMP traps. For

information on configuring the SNMP agent using the

agtCfgSet

command, see the

HP StorageWorks

Fabric OS 5.x command reference guide

.

SNMP trap

The Simple Network Management Protocol (SNMP) performs an operation called a

trap

that notifies a

management station (a workstation that runs network management applications using SNMP protocol)

when events occur.

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 using the

agtCfgSet

command. For more information on this command, refer to the

HP StorageWorks Fabric OS 5.x command

reference guide.

An SNMP trap forwards the following information to an SNMP management station:

•

Name of the element whose counter registered an event

•

Class, area, and index number of the threshold that the counter crossed

•

Event type

•

Value of the counter that exceeded the threshold

•

State of the element that triggered the alarm

•

Source of the trap
