failed to write data using prometheus remote_write about greptimedb HOT 4 CLOSED

@GoneLikeAir Thank you for your report! I will confirm it based on your description.

from greptimedb.

@GoneLikeAir, is this an issue that must occur? Based on my environment, I can't reproduce your problem. Can you give me more information, for example:

• the specific steps
• more key error log of other components, for example, datanode or frontend;

The following are my steps for using remote write and read:

• Install GreptimeDB cluster by the guide. After installation, I use kubectl port-forward to expose 4000 and 4002;

• Install node exporter:

docker run -d \
  --net="host" \
  --pid="host" \
  -v "/:/host:ro,rslave" \
  quay.io/prometheus/node-exporter:latest \
  --path.rootfs=/host

• Install Prometheus

docker run --network=host \ -p 9090:9090 \ -v /tmp/prometheus.yml:/etc/prometheus/prometheus.yml \ prom/prometheus

And here is my prometheus.yml:

global:
  scrape_interval: 15s

scrape_configs:
- job_name: node
  static_configs:
  - targets: ['localhost:9100']

remote_write:
- url: http://localhost:4000/v1/prometheus/write?db=public&physical_table=greptime_physical_table

remote_read:
- url: http://localhost:4000/v1/prometheus/read?db=public

• Use mysql to read the data:

mysql -h 127.0.0.1 -P 4002

I think it's a compatible issue. Do you still have this problem? @GoneLikeAir
