Potential Impact to OneAgent Customers Running nginx on Alpine

Update timeline

1. identified Jul 14, 2026, 11:10 AM UTC

   We have identified that the Alpine Linux distribution of nginx 1.28.3 on Alpine Linux 3.22 and 3.23 introduces an issue when used together with Dynatrace OneAgent nginx instrumentation. Affected environments may experience HTTP 500 responses or missing monitoring data, including traces and Real User Monitoring. Available mitigations include upgrading to OneAgent version 1.337 or later, upgrading to an unaffected Alpine Linux version, or disabling the OneAgent feature "Nginx modules". For more details on affected configurations and available workarounds, please refer to our Community post: https://community.dynatrace.com/t5/Heads-up-from-Dynatrace/Specific-Alpine-Linux-versions-introduce-a-compatibility-issue/ta-p/301869 We are working with the Alpine Linux maintainers to address the underlying issue and will provide updates as more information becomes available. We apologize for the inconvenience.
