F5 BIG-IP Trigger

F5 BIG-IP Trigger
Certified
Enterprise Edition
React when a BIG-IP LTM pool member reaches a specific state

Polls all members of the configured pool at the given interval and fires an execution for each member whose monitored state matches watchedState. The output variables trigger.memberName, trigger.state, and trigger.pool are available in downstream tasks.

type: io.kestra.plugin.ee.f5.poolmember.Trigger

Examples

Alert when a pool member goes down

    host: "{{ secret('F5_HOST') }}"
    username: "{{ secret('F5_USERNAME') }}"
    password: "{{ secret('F5_PASSWORD') }}"
    pool: my-app-pool
    watchedState: DOWN
    interval: PT1M

tasks:
  - id: alert

    message: "Pool member {{ trigger.memberName }} went {{ trigger.state }} in pool {{ trigger.pool }}"

Properties

host *string

BIG-IP hostname or IP address

password *string

BIG-IP password

pool *string

Pool name or full path to watch

username *string

BIG-IP username

allowConcurrent boolean

Defaultfalse

Specifies whether a trigger is allowed to start a new execution even if a previous run is still in progress.

insecure booleanstring

Defaultfalse

Trust all SSL certificates

Set to true to disable TLS certificate validation.

interval string

DefaultPT1M

Formatduration

Polling interval

How often to poll for state changes. Accepts ISO 8601 duration notation, e.g. PT30S for 30 seconds or PT1M for 1 minute.

partition string

DefaultCommon

Administrative partition to target

Defaults to Common when not set.

stopAfter array

SubTypestring

Possible Values

CREATEDSUBMITTEDRUNNINGPAUSEDRESTARTEDKILLINGSUCCESSWARNINGFAILEDKILLEDCANCELLEDQUEUEDRETRYINGRETRIEDSKIPPEDBREAKPOINTRESUBMITTED

List of execution states after which a trigger should be stopped (a.k.a. disabled).

watchedState string

DefaultDOWN

Possible Values

UPDOWNDISABLEDFORCED_OFFLINE

Member state that triggers an execution

The trigger fires once per member that is currently in this state.

when string

Defaulttrue

A condition that determines whether the trigger should run.

A Pebble expression evaluated at trigger time. The trigger fires only when the expression evaluates to a truthy value (true, a non-empty string, a non-zero number). Use this to gate trigger execution on dynamic runtime values such as execution labels, flow variables, or environment conditions.

Outputs

memberName string

Name of the pool member that matched watchedState

pool string

Pool name that was polled

state string

Effective state of the pool member at evaluation time
