Using the Talk event handler
With the Talk event handler enabled and configured in your
.talk() attribute in your TICKscripts to send alerts to Talk or define
a Talk handler that subscribes to a topic and sends published alerts to Talk.
Send alerts to Talk from a TICKscript
The following TICKscript sends the message, “Hey, check your CPU”, to Talk
whenever idle CPU usage drops below 10% using the
.talk() event handler.
stream |from() .measurement('cpu') |alert() .crit(lambda: "usage_idle" < 10) .message('Hey, check your CPU') .talk() .title('Alert from Kapacitor')
Send alerts to Talk from a defined handler
The following setup sends an alert to the
cpu topic with the message,
“Hey, check your CPU”.
A Talk handler is added that subscribes to the
cpu topic and publishes all
alert messages to Talk.
Create a TICKscript that publishes alert messages to a topic.
The TICKscript below sends an alert message to the
cpu topic any time idle CPU
usage drops below 10%.
stream |from() .measurement('cpu') |alert() .crit(lambda: "usage_idle" < 10) .message('Hey, check your CPU') .topic('cpu')
Add and enable the TICKscript:
kapacitor define cpu_alert -tick cpu_alert.tick kapacitor enable cpu_alert
Create a handler file that subscribes to the
cpu topic and uses the Talk event
handler to send alerts to Talk.
id: talk-cpu-alert topic: cpu kind: talk options: title: Alert from Kapacitor
Add the handler:
kapacitor define-topic-handler talk_cpu_handler.yaml
