Notifications: content send via http endpoint

InfluxDB 2 Checks & Notifications
,
1

Hello,

I made an notification using a http-Endpoint… Its working fine, but all information from the table row are send although only few should be send. I want to drop not necessary information and used the drop function. A check in the raw data show that the drop function works well, but I guess that this is only functioning for the data send to the bucket _monitoring, while some lines before in the code the information was already send to the http-Endpoint.

My question would be: How I can control the information that are send over the http-Endpoint?
Greetings

import "influxdata/influxdb/monitor"
import "influxdata/influxdb/v1"

data = from(bucket: "HeatMetering")
    |> range(start: -30m)
    |> filter(fn: (r) => r["_measurement"] == "Netz")
    |> filter(fn: (r) => r["_field"] == "TempFlow_C")
    |> aggregateWindow(every: 30m, fn: mean, createEmpty: false)

option task = {name: "Flow Temp monitoring", every: 30m, offset: 0s}

check = {_check_id: "0871667070d13000", _check_name: "Flow Temp monitoring", _type: "threshold", tags: {}}
warn = (r) => r["TempFlow_C"] < 74.0
messageFn = (r) => "${r._check_name} hat Status: ${r._level}"

data |> v1["fieldsAsCols"]() |> monitor["check"](data: check, messageFn: messageFn, warn: warn)
    |> drop(
        columns: [
            "_measurement",
            "_check_id",
            "_level",
            "_source_measurement",
            "_source_timestamp",
            "_start",
            "_stop",
            "_time",
            "_type",
            "DeviceId",
            "User",
        ],
    )

does anybody had an idea what can I test? I’m using a App that will notify me when the Alert is true… but beside the important information “TempFlow_C”, all standard information listed below are send via the http endpoint and shown in the App. With that big amount of information, the relevant information will not be recognized fast as it should be.

_Check_Id
_Check_Name
_level
_Version
_measurement
_Notification_Endpoint_Id
_Notification_Endpoint_Name
_Notification_Rule_Id
_Notification_Rule_Name
_Source_Measurement
_Source_timestamp
_Start
_Status_Timestamp
_Stop
_Time
_Type

The solution I found was to make the check and alerting only as a task… with the standard alert procedure from InfluxDB Clould seems there is no way to get rid of the listed standard entries.
