How to enable a Feature Gate

[RoeiDimi]

Hi all,
I added a parser with a feature gate that can be seen here -

opentelemetry-collector-contrib/pkg/stanza/operator/parser/jsonarray/json_array_parser.go

Line 31 in 63eb22b

if jsonArrayParserFeatureGate.IsEnabled() {

But now, i'm not sure how to enable it..
I saw this link and tried running the collector with all the following variations but none worked -

otelcol --config=config.yaml --feature-gates=logs.jsonParserArray
otelcol --config=config.yaml --feature-gates=+jsonParserArray
otelcol --config=config.yaml --feature-gates=jsonParserArray

Any idea what im doing wrong?
Thanks!

Hi @djaglowski ,
Any chance you can help with that question?

[djaglowski]

Looks like we have a bug which causes this feature gate to be registered after we check for it: #32313

@djaglowski
would you like me to remove the flag? or move it somewhere else (not in the parser's init maybe?)

[djaglowski]

I think we need to keep the gate but issues are open already which will hopefully resolve the problem.

• [featuregate] add Gate.featureGateEnableFunc for --feature-gates registered opentelemetry-collector#9964
• [pkg/stanza] fix collector start fail with '--feature-gates=logs.json… #32376

I submitted #32501 To solve this problem.

I have the same problem, recommended document: otelcol --config=config.yaml --feature-gates=logs.jsonParserArray
