### What did you see?

After upgrading Cisco Secure Email Gateways (C695) to version 16.0.4-016, the status log messages changed.
Therefore, the grok filter in the ingest pipeline logs-cisco_secure_email_gateway.log-1.28.4-pipeline_status no longer matches.

**Log example before the update from Version 14.x:**
