Data source is working but no data points!

Grafana InfluxDB
#1

Good morning, I’m french, sorry for my bad english.

I want to display somes data from an esp8266 to grafana. I have installed : mosquitto + nodered + influxdb + grafana.

In the debug message of nodered I see my data, I have created an “influxdb out node” to an influxdb database. In grafana when I settings a new database, I have this message : “data source is working”, but on the dashboard I see “No data points” despite various configuration tests. Is somebody can help me ?

Thanks, Christophe.

Please tell us what you have installed it on - which operating system, which
version?

mosquitto + nodered + influxdb + grafana.

Please show us the configuration files you have set up for these.

In the debug message of nodered I see my data, I have created an “influxdb
out node” to an influxdb database. In grafana when I settings a new
database, I have this message : “data source is working”, but on the
dashboard I see “No data points” despite various configuration tests.

Tell us what “configuration tests” you have done and what the results were.

Basically, give us enough information to understand what you have set up, and
to reproduce it for ourselves if necessary.

Regards,

Antony.

I have exactly the same problem !
I have tried several solution in past days, but nothingh works.
os:windows10
Data sent to influxDB Cloud from node-red. No problem
I can see everithyng on InfluxDB CLoud. No Problem
It shows values of temperature and Luminosity from sensors
But when try to configure Grafana Cloud…

  • I put my url: https://eu-central-1-1.aws.cloud2.influxdata.com
  • I put Database (mlBucket. The Bucket name created in influxDB)
  • I put user (my mail addres)
  • I put password (Token conected to mlBucket in influxDB)
    Save & Test - Says Says “Data source is working”

Then I try to create a Dashboard with this Data source, and no data appears.
Also appears “influxDB error: database not found: mlBucket”

What Iam doing Wrong ?
I will apreciate any assistance.
(I am stucked on this for almost 2 weeks…)
