Add support to custom log level through command line flag and environment variable #842

vitorhugoro1 · 2024-05-13T17:49:25Z

Added on InstrumentationOption the option to define log level.
Implemented a custom severity enum, called level.go, with options to set log levels based on text using zap.Level as reference.
Added on CLI the flag -log-level that accept one of LogLevel value, which can be see on level.go ex. otel-go-instrumentation -log-level error, the default value is info.
Added support to OTEL_LOG_LEVEL which implements LogLevel to set visibility level through environment variable.
Changed multiples logs level to Debug to improve setup when using in production environment.
Closes Add log verbosity configuration and move the log in controller.go to debug level #691

@vitorhugoro1 Do you plan on changing the level of the log line I mentioned in the issue?
In addition, we can use debug level in our tests at

opentelemetry-go-instrumentation/.github/workflows/e2e/k8s/sample-job.yml

Line 29 in e85ddd9

command: ["/otel-go-instrumentation", "-global-impl"]

pellared

Shouldn't we support setting via OTEL_LOG_LEVEL env var?

That is tracked in #691. It is out of scope for this PR.

Yeah this PR will implement this change too, I take the approach just with flags because is the way I usually use log levels on container

I changed some log level, not just in the line you mentioned but in another which is more suitable to debugging not exactly on a production setup.

Changed the sample job too to use debug level by default
