Monitor FCIP circuit QoS
FOS v7.4 enhances FCIP QoS monitoring in MAPS to add monitoring of Fibre Channel QoS parameters at circuit
level. The circuit QoS monitoring combined with the tunnel QoS monitoring available since FOS v7.3 provides
additional granularity to monitor the FCIP link performance.
Monitor FCIP circuit RTT and jitter on 7800 and FX8-24
MAPS monitors circuit round trip time (RTT) and jitter statistics in FOS v7.3 on Brocade 7840. FOS v7.4
supports these two FCIP circuit monitoring elements on Brocade 7800 and FX8-24 blade so that they are
available to 8G FC extension platforms.
Fabric Performance Impact monitoring enhancement
FOS v7.4 enhances Fabric Performance Impact (FPI) monitoring to add a new IO_LATENCY_CLEAR state so that
end users can receive notification when latency conditions are cleared. FOS v7.4 enhances FPI monitoring by
adding latency counter monitoring on all ports to detect potential transient spikes of latency conditions. In
addition, FOS v7.4 moves port TX, RX, and UTIL monitoring systems to the FPI category from the Port Health
category in FOS v7.3 and earlier releases so that all potential congestion conditions are reported under the FPI
category.
Slow drain device quarantine action for Fabric Performance Impact monitoring
FOS v7.4 introduces a new MAPS action that automatically isolates slow drain devices when they are detected
by FPI monitoring. This frees up buffer credits for normal devices that are sharing the same links and mitigates
the effect due to presence of slow drain devices in the fabric.
Port toggle action for Fabric Performance Impact monitoring
FOS v7.4 introduces Port Toggle as an action which automatically recovers slow drain device conditions when
they are detected by FPI monitoring. A port toggle, (which is a port disable followed by a port enable) can
recover the ports from some slow drain device conditions or force traffic failover to an alternate path.
FICON notification action
FOS v7.4 introduces FICON notification as a new action that enables MAPS events to be sent to FMS with
detailed event information upon rule violations. FMS CUP can translate these MAPS events into FICON-specific
Health Summary Check reports.
Alert quiet time support
FOS v7.4 introduces a quiet time support for RASLOG and EMAIL alert actions. This feature allows end users to
configure within a rule a period of time not to receive duplicated alerting actions after the first alert has already
been sent.
Usability enhancements
FOS v7.4 has a number of usability enhancements to MAPS. These include:
Allow none to be used as an email address to clear previously configured email addresses in the CLI
•
command mapsconfig.
Enhanced Temperature Sensor monitoring so that actions are triggered on change of Temperature Sensor
•
(TS) states.
Modified FRU monitoring so that the states being monitored are more accurate and useful for operations.
•
An upper limit to the number of rules that can be created in a policy. The maximum number of rules in a
•
policy is dependent on the character length of each rule name.
Flow Vision Enhancements
FOS v7.4 provides the following enhancements to Flow Vision:
All F_Port Flow Monitoring
FOS v7.4 introduces a system predefined learning flow named sys_mon_all_fports to monitor performance on
all F_ports in a switch. Flow learning on all F_ports provides a continuous, automatic, and comprehensive view
of application traffic patterns for all device connections.
