python influxdb check success boolean

[Bra1nsen]

Dear Developer,

how can one check back if the data reached influxdb cloud 2.x?

I use something like that:

        write_api = client.write_api(write_options=SYNCHRONOUS)
        p = influxdb_client.Point("Kameradom").field("Temperatur", temperature).field("Druck", pressure)
        write_api.write(bucket=bucket, org=org, record=p)

I just would like to get an boolean if write_api worked or not.

Sorry I know its not the right place to ask something like that but you guys can answer that within 30 seconds while I would have to google for 4 hours.Thanks

Hi @Bra1nsen,

thanks for using our client.

If the write_api.write(bucket=bucket, org=org, record=p) doesn't throws an error it means that data was successfully written.

thanks for the quick response.

I just want to add a function, which reboots the weather station once if data isnt arriving. I need some kind of a boolean return or similiar. thanks ahead

You can use something like this:

from datetime import datetime

from influxdb_client import WritePrecision, InfluxDBClient, Point
from influxdb_client.client.write_api import SYNCHRONOUS

with InfluxDBClient(url="http://localhost:8086", token="my-token", org="my-org", debug=False) as client:
    p = Point("my_measurement") \
        .tag("location", "Prague") \
        .field("temperature", 25.3) \
        .time(datetime.utcnow(), WritePrecision.MS)

    try:
        client.write_api(write_options=SYNCHRONOUS).write(bucket="my-bucket", record=p)
        reboot = False
    except Exception as e:
        reboot = True

    print(f"Reboot? {reboot}")

great thanks

Hey bednar. I would like to add some kind of condition, so that it only reboots, if the data is not sent for longer than 5 minutes/ exception persists.

I tried:

	except Exception as e:
		time.sleep(300)
		reboot = True	

in hope that the reboot boolean stays false after the try: works again, but after the 300s the reboot gets true.

I need something like, if Exception holds on for 5 minutes: reboot = True. thank you

You can keep datetime when the exception shows and compare this date with actual time.
