Walkthrough

This change updates the "Harvester metrics" documentation section in filebeat-input-filestream.md.

TL;DR

check-docs failed in the check job because go vet ./... no longer compiles metricbeat/mb/module/runner_test.go: line 173 passes a *logp.Logger where module.NewWrapper now expects *beat.Info. Wrap the test logger in &beat.Info{Logger: ...} and rerun the scoped Metricbeat check.

Remediation

• Update metricbeat/mb/module/runner_test.go:173 from logptest.NewTestingLogger(t, "") to &beat.Info{Logger: logptest.NewTestingLogger(t, "")} in the module.NewWrapper(...) call.
• Validate with cd metricbeat && go test ./mb/module or the failing CI path cd metricbeat && mage check.

Investigation details

Root Cause

module.NewWrapper is called with the wrong third argument type in metricbeat/mb/module/runner_test.go:173. Nearby calls in the same file already pass &beat.Info{Logger: logptest.NewTestingLogger(t, "")}, and metricbeat/mb/module/wrapper.go:93 defines the parameter as info *beat.Info.

Evidence

• Workflow: https://github.com/elastic/beats/actions/runs/28664138195
• Job/step: check / Run check
• Key log excerpt:

2026-07-03T13:45:44.5034650Z >> check: Checking source code for common problems
2026-07-03T13:45:46.3352055Z # github.com/elastic/beats/v7/metricbeat/mb/module_test
2026-07-03T13:45:46.3457026Z ##[error]vet: mb/module/runner_test.go:173:51: cannot use logptest.NewTestingLogger(t, "") (value of type *logp.Logger) as *beat.Info value in argument to module.NewWrapper
2026-07-03T13:45:52.6591860Z Error: failed running go vet, please fix the issues reported: running "go vet ./..." failed with exit code 1

Validation

• Not run locally; this report is based on the CI log plus source inspection of the failing call and module.NewWrapper signature.

Follow-up

• This failure is outside the one docs file changed by this PR, so if it came from merging main, the fix likely belongs on the PR branch as a small compatibility fix or should be resolved in main before re-running.
