Remove the three agent-side replace processors that normalized hyphenated CEF field names (PanOSX-Forwarded-ForIP, PanOSX-Forwarded-For, PanOSSplit-tunnelconfiguration) before decode_cef. The underlying decode_cef bug (elastic/beats#40348) is fixed in Elastic Agent 8.16.0, so the minimum kibana version is bumped to 8.16.0. The normalization now happens in the ingest pipeline via rename processors, keeping downstream field references unchanged. The remaining replace processor for '\=' in URLs is retained with a 'when.contains' guard so it only runs when the message actually contains '\='. In heap profiling, the four regex replace processors accounted for 137 MB (10.4%) from regexp.ReplaceAllString allocations, plus additional overhead from event.Clone on every invocation due to fail_on_error. Removing three of the four fields and adding the conditional eliminates most of this cost.
💚 Build Succeeded
