FPI monitoring category
The FPI category groups areas that measures the thresholds on the performance of the fabric.
lists measures in the FPI category and describes the measure.
MAPS policies
A MAPS policy is a set of rules that define thresholds for measures and action to take when a
threshold is triggered. When you enable a policy, all of the rules in the policy are in effect.
A device can have multiple policies. For example, you can have a policy for everyday use and you
can have another policy for when you are running backups or performing switch maintenance.
However, only one policy can be active at a time. When you enable a policy, it becomes the active
policy and the rules in the active policy take effect.
At any time, one policy must always be active on the switch. You can have an active policy with no
rules, but you must have an active policy. You cannot disable the active policy. You can only change
the active policy by enabling a different policy.
Preconfigured policies
MAPS provides three preconfigured policies. You cannot modify or delete these policies. The
preconfigured policies include the following:
•
dflt_aggressive_policy
Contains rules with very strict thresholds. Use this policy if you need a pristine fabric (for
example, FICON fabrics).
•
dflt_conservative_policy
Contains rules with more lenient thresholds that allow a buffer and do not immediately trigger
actions. Use this policy in environments where the elements are resilient and can
accommodate errors.
This is the default policy unless you specify another policy when you enable MAPS on the
device and migrate from Fabric Watch to MAPS using the mapsconfig --migrate –enablepolicy
policy_name command
•
dflt_moderate_policy
Contains rules with thresholds values between the aggressive and conservative policies.
Although you cannot modify the preconfigured policies, you can create a policy based on these
policies. For more information, refer to
