Eaa Environment Variables - HP 5920 Configuration Manual

Event type
SNMP_Notification
Action
You can create a series of order-dependent actions to take in response to the event specified in the
monitor policy.
The following are available actions:
• Executing a command.
Sending a log.
•
Enabling an active/standby switchover.
•
Executing a reboot without saving the running configuration.
•
User role
For EAA to execute an action in a monitor policy, you must assign the policy the user role that has access
to the action-specific commands and resources. If EAA lacks access to an action-specific command or
resource, EAA does not perform the action and all the subsequent actions.
For example, a monitor policy has four actions numbered from 1 to 4. The policy has user roles that are
required for performing actions 1, 3, and 4, but it does not have the user role required for performing
action 2. When the policy is triggered, EAA executes only action 1.
For more information about user roles, see RBAC in Fundamentals Configuration Guide.
Runtime
Policy runtime limits the amount of time that the monitor policy can run from the time it is triggered. This
setting prevents system resources from being occupied by incorrectly defined policies.

EAA environment variables

EAA environment variables decouple the configuration of action arguments from the monitor policy so
you can modify a policy easily.
An EAA environment variable is defined as a <variable_name variable_value> pair and can be used in
different policies. When you define an action, you can enter a variable name with a leading dollar sign
($variable_name) instead of entering a value for an argument. EAA will replace the variable name with
the variable value when it performs the action.
To change the value for an action argument, modify the value specified in the variable pair instead of
editing each affected monitor policy.
EAA environment variables include system-defined variables and user-defined variables.
System-defined variables
System-defined variables are provided by default, and they cannot be created, deleted, or modified by
users. System-defined variable names start with an underscore (_) sign, and variable values are set
automatically by the system depending on the event setting in the policy that references the variables.
System-defined variables include the following types:
Public variable—Available for any events.

Description
SNMP_Notification event occurs when the monitored MIB variable's value in an SNMP
notification matches the specified condition. For example, the broadcast traffic rate on
an Ethernet interface is equal to or greater than 30%.
