elastic-agent/internal/pkg/otel/translate/otelconfig.go

Line 42 in 3e93cab

OtelSupportedInputTypes = []string{"filestream", "http/metrics", "beat/metrics", "system/metrics"}

needs to be expanded to include all the inputs for filebeat and metricbeat

Closing since #10785 adds the necessary inputs for M1-c. We will need to add more as we expand but I think we want to have elastic/elastic-package#2975 in place before we go to far down that path.
