Configuring Kapacitor to Send Alerts to Grafana OnCall

To send an alert from Kapacitor, you can follow these steps:

Create a Kapacitor TICKscript or modify an existing one to define the conditions for triggering the alert. The TICKscript specifies the data source, data processing, and the alert rule. Here’s an example of a simple TICKscript:

stream
    |from()
        .measurement('measurement_name')
        .where(lambda: <condition>)
    |alert()
        .webhook('<webhook_url>')

Replace 'measurement_name' with the name of the measurement you want to monitor, <condition> with the condition that triggers the alert, and '<webhook_url>' with OnCall Integration URL 2. Save the TICKscript file with a .tick extension, for example, alert_script.tick. 3. Start the Kapacitor service using the TICKscript:

kapacitor define <alert_name> -tick /path/to/alert_script.tick
kapacitor enable <alert_name>
kapacitor reload

Replace <alert_name> with a suitable name for your alert. 4. Ensure that the Kapacitor service is running and actively monitoring the data. When the condition defined in the TICKscript is met, Kapacitor will trigger the alert and send a POST request to the specified webhook URL with the necessary information. Make sure your webhook endpoint is configured to receive and process the incoming alerts from Kapacitor.
