monitor.notify() function

monitor.notify() sends a notification to an endpoint and logs it in the notifications measurement in the _monitoring bucket.

Function type signature
    <-tables: stream[E],
    data: A,
    endpoint: (<-: stream[{B with _time: C, _time: time, _status_timestamp: int, _measurement: string}]) => stream[D],
) => stream[D] where A: Record, D: Record, E: Record

For more information, see Function type signatures.



(Required) A function that constructs and sends the notification to an endpoint.


(Required) Notification data to append to the output.

This data specifies which notification rule and notification endpoint to associate with the sent notification. The data record must contain the following properties:

  • _notification_rule_id
  • _notification_rule_name
  • _notification_endpoint_id
  • _notification_endpoint_name The InfluxDB monitoring and alerting system uses monitor.notify() to store information about sent notifications and automatically assigns these values. If writing a custom notification task, we recommend using unique arbitrary values for data record properties.


Input data. Default is piped-forward data (<-).


Send critical status notifications to Slack

import "influxdata/influxdb/monitor"
import "influxdata/influxdb/secrets"
import "slack"

token = secrets.get(key: "SLACK_TOKEN")

endpoint =
    slack.endpoint(token: token)(
        mapFn: (r) => ({channel: "Alerts", text: r._message, color: "danger"}),

notification_data = {
    _notification_rule_id: "0000000000000001",
    _notification_rule_name: "example-rule-name",
    _notification_endpoint_id: "0000000000000002",
    _notification_endpoint_name: "example-endpoint-name",

monitor.from(range: -5m, fn: (r) => r._level == "crit")
    |> range(start: -5m)
    |> monitor.notify(endpoint: endpoint, data: notification_data)

The future of Flux

Flux is going into maintenance mode. You can continue using it as you currently are without any changes to your code.

Flux is going into maintenance mode and will not be supported in InfluxDB 3.0. This was a decision based on the broad demand for SQL and the continued growth and adoption of InfluxQL. We are continuing to support Flux for users in 1.x and 2.x so you can continue using it with no changes to your code. If you are interested in transitioning to InfluxDB 3.0 and want to future-proof your code, we suggest using InfluxQL.
