mc admin logs

SUBNET Registration Required

The mc support commands are designed for MinIO deployments registered with MinIO SUBNET to ensure optimal outcome of diagnostics and performance testing. Deployments not registered with SUBNET cannot use the mc support commands.

Changed in version RELEASE.2022-12-02T23-48-47Z: mc support logs moved to mc admin logs and provide a simpler command interface for displaying server logs for the MinIO deployment.

The output is similar to what is available via journalctl -uf minio for systemd-controlled deployments.


Use the mc admin logs command to show MinIO server logs.

To enable or disable the sending of logs to SUBNET for support, use mc support callhome.

The uploading feature remains disabled by default until explicitly enabled for a deployment on an opt-in only basis. If enabled, you can disable the feature at any time with mc support callhome disable.
