The MinIO TLS STS API can be configured via MinIO's standard configuration API (i.e. using `mc admin config set/get`). Further, it can be configured via the following environment variables:

```

| `minio_system_drive_io_errors_total`           | `counter` | Total I/O errors on a drive                                        | `drive,set_index,drive_index,pool_index,server`     |
| `minio_system_drive_availability_errors_total` | `counter` | Total availability errors (I/O errors, timeouts) on a drive        | `drive,set_index,drive_index,pool_index,server`     |
