no bitcoin metrics

[haumanto]

Hi,

I tried to run this but no bitcoin metrics are generated… almost all of them are 0…

Please help…

Hi @haumanto,

It sounds like the connection to the bitcoin node is not working.

1. How are you running the exporter (e.g. via docker, directly with python)?
2. What is the full output of the exporter when you set LOG_LEVEL=DEBUG as an environment variable, and then visit the metrics endpoint (e.g. http://localhost:9332/metrics)?

I'm experiencing this same issue, running on a VM with the requirements installed globally on Python 3.6.

The debug log output:

@xr09 - What node software and version are you running?

The error message is giving the documentation text back for the getmemoryinfo RPC. I would guess the node software doesn't support the stats argument.

Indeed, I was pointing to the wrong node, will try again with the right settings.

Thanks @jvstein!
