Influxdb3 output health-check
Influxdb3 is available for some time, today I tried to use it and getting errors on health check If I remove health-check-period then everything works.
From documentation system token is needed https://docs.influxdata.com/influxdb3/enterprise/admin/tokens/resource/create/#create-a-system-token
Then u can use curl http://localhost:8181/health --header "Authorization: Bearer apiv3_token" OK
outputs:
influxdb-output:
type: influxdb
url: http://10.81.138.10:8181

token: apiv3_tokenxxxxxxxxxxxxxxxxxxx
batch-size: 1000
flush-timer: 10s
health-check-period: 60s
event-processors:

It looks like influxdb3 returns an OK string as a response on the health endpoint instead of a JSON message.
Influxdb3 is not supported by the library gNMIc uses (https://github.com/influxdata/influxdb-client-go).
There is a separate V3 client lib: https://github.com/InfluxCommunity/influxdb3-go
If you still want to run influxdb3 there might be corner cases where things fail.
