Triggers

You can configure FortiADC to automatically respond to the following trigger events: Security Events, SLB Metric, Period Block IP, HA failover, System Metrics, Schedule, System Events, and Interface Metric. The following table provides more information about the trigger event list.

Trigger

Description

Security Events

Event

Select the security events that will trigger the action.

Rolling Window

Enable to define a Rolling Window Time and Number of Occurence (see below). The Rolling Window Time sets a period of time in which a number of events must take place for an action to be triggered. The number of events that must take place within this period of time is set in the Number of Occurrences option.

Rolling Window Time

Specify the range of time (in seconds) for the rolling window.

Available only when Rolling Window is enabled (see above).

Number of Occurrences

Specify the number of events that must take place before FortiADC will trigger the action.

Available only when Rolling Window is enabled (see above).

SLB Metric

Performance Event

Select the server load balance performance events that will trigger the action.

Comparator

The metric is compared to the Value field according to the selected option:

  • Ge—greater than

  • Le—less than

  • Eq—equal to

The action will be triggered if the specified value satisfies the selected option.

Value

Specify the metric value that the Comparator uses to determine if the metric triggers an action, for example, 2 milliseconds.

Virtual Server

Select the virtual server on which the SLB Metric trigger applies.

Duration

Session duration.

Period Block IP

Period Block IP

Select this trigger to retrieve the Source IP addresses from Period Block list.

HA Failover

Event

Select the HA failover events that will trigger the action.

Rolling Window

Enable to define a Rolling Window Time and Number of Occurence (see below). The Rolling Window Time sets a period of time in which a number of events must take place for an action to be triggered. The number of events that must take place within this period of time is set in the Number of Occurrences option.

Rolling Window Time

Specify the range of time (in seconds) for the rolling window.

Available only when Rolling Window is enabled (see above).

Number of Occurrences

Specify the number of events that must take place before FortiADC will trigger the action.

Available only when Rolling Window is enabled (see above).

System Metrics

Performance Event

Select the system metrics events (average CPU usage, average memory usage, etc.) that will trigger the action.

Comparator

The metric is compared to the Value field according to the selected option:

  • Ge—greater than

  • Le—less than

  • Eq—equal to

The action will be triggered if the specified value satisfies the selected option.

Value

Specify the metric value that the Comparator uses to determine if the metric triggers an action.

Duration

Event duration.

Schedule

Frequency

Select the frequency of the action, that is, whether the action will be executed hourly, daily, weekly, or monthly.

Trigger Minute/Hour

The action will be executed at the specified Hour:Minute.

System Events

Performance Event

Select the system events (bad PSU fan, good device fan, etc.) that will trigger the action.

Rolling Window

Enable to define a Rolling Window Time and Number of Occurence (see below). The Rolling Window Time sets a period of time in which a number of events must take place for an action to be triggered. The number of events that must take place within this period of time is set in the Number of Occurrences option.

Rolling Window Time

Specify the range of time (in seconds) for the rolling window.

Available only when Rolling Window is enabled (see above).

Number of Occurrences

Specify the number of events that must take place before FortiADC will trigger the action.

Available only when Rolling Window is enabled (see above).

Interface Metric

Event

Select the network interface events that will trigger the action.

Comparator

The metric is compared to the Value field according to the selected option:

  • Ge—greater than

  • Le—less than

  • Eq—equal to

The action will be triggered if the specified value satisfies the selected option.

Value

Specify the metric value that the Comparator uses to determine if the metric triggers an action.

Interface

Select the network interface on which the Interface Metric trigger applies.

Duration

Event duration.
