promtail-client

This is a fork from https://github.com/afiskon/promtail-client which adds prefixFormat, I hope this is temporal until my PR is reviewed.

Promtail client library. Promtail is an agent for Loki logging system.

This library supports both JSON and Protobuf APIs.

Usage example:

cd examples/client-example
go build

# make sure source-name is unique for every application instance
# otherwise promtail will reject logs with error:
# "entry out of order for stream"
./client-example proto source-name job-name
