Threshold Area Values
Threshold area values include boundaries and alarms, and apply to all the thresholds within an area.
Changes are stored in the configuration file.
Boundaries
The following boundary information can be modified:
Unit string Represents unit value. Only the default unit strings are supported by
Fabric Watch.
Time base Time period within which a specified event is measured. Can be
from one second to one day. Shorter time periods are more sensitive
to fluctuations and therefore will provide more detailed
information.
Note:
The Time base boundary can only be modified through a
telnet command. The Time base bounder does not apply to
the:
- Transmit performance area
- Receive performance area
- Filter class
Low boundary Minimum value. An event is generated if the element value falls
below this boundary.
High boundary Maximum value. An event is generated if the element value rises
above this boundary.
Buffer size Size of buffer set up to decrease generation of in-between events
due to oscillation of the element value over a boundary.
Alarms
The following alarms can be added or deleted:
ERRLOG Logs errors to switch. If configured properly, sends message to
syslog on daemon.
SNMP-TRAP Sends trap to SNMP agent.
PORT-LOG-LOCK Freezes port log to preserve log information generated at time of
event, for diagnostic purposes.
RAN Sends alarm messages to remote agent.
Note: The RAN alert is only available if the optional Fabric Access
license has been purchased and turned on.
Email Alert Sends alarm messages to the corresponding mail address.
