The purpose of this repo is to show how one can write an opentelemetry collector log processor. It does not really do anything but to add some "hello":"world" entry to all log records.
The OpenTelemetry collector project has provided a tutorial for writing an OTEL collector receiver for traces. Although the reason for creating this helloworld log processor repo was to explore log processor writing, the information in the receiver tutorial is very helpful as it explains common concepts for components such as life cycle and configuration. So before reading further here it is suggested that you first read the OTEL receiver tutorial at https://opentelemetry.io/docs/collector/trace-receiver/.
go build cmd/main.go./main --config example.yaml(this starts the collector with a file logger that reads from the file "tmp.json" which will pass the data on to the helloworldlogsprocessor)
sh test.sh(this writes some log entries to tmp.json in the form of structured json log entries)
