AMA: enable libcurl ODS upload (ENABLE_CURL_UPLOAD) in eastus2euap and centraluseuap#2190
Merged
Merged
Conversation
Gate the libcurl-based ODS upload path behind region detection using the existing is_feature_enabled/feature_support_matrix mechanism. enableCurlUpload is scoped to eastus2euap for canary rollout; when enabled, the extension writes export ENABLE_CURL_UPLOAD=true to /etc/default/azuremonitoragent. Per-VM previewFeatures override flag files continue to force enable/disable.
