Description

The mc admin trace command displays API operations occurring on the target MinIO deployment.

Use mc admin on MinIO Deployments Only

MinIO does not support using mc admin commands with other S3-compatible services, regardless of their claimed compatibility with MinIO deployments.

Use mc admin trace to monitor API operations on a MinIO deployment:

mc admin trace -a ALIAS

Use mc admin trace to monitor API operations that return a service unavailable 503 error:

mc admin trace -v --status-code 503 ALIAS

Use mc admin trace to monitor activity for a specific path:

mc admin trace --path my-bucket/my-prefix/* ALIAS

Replace ALIAS with the alias of the MinIO deployment.
Replace my-bucket/my-prefix/* with the bucket, prefix, and object name or wildcard you wish to trace.

mc admin trace has the following syntax:

mc admin trace [FLAGS] TARGET
