# MinIO Server Debugging Guide [](https://slack.min.io) [](https://hub.docker.com/r/minio/minio/)
|
|
|
|
### HTTP Trace
|
|
HTTP tracing can be enabled by using [`mc admin trace`](https://github.com/minio/mc/blob/master/docs/minio-admin-complete-guide.md#command-trace---display-minio-server-http-trace) command.
|
|
|
|
Example:
|
|
```sh
|
|
minio server /data
|
|
```
|
|
|
|
Default trace is succinct only to indicate the API operations being called and the HTTP response status.
|
|
```sh
|
|
mc admin trace myminio
|
|
```
|
|
|
|
To trace entire HTTP request
|
|
```sh
|
|
mc admin trace --verbose myminio
|
|
```
|
|
|
|
To trace entire HTTP request and also internode communication
|
|
```sh
|
|
mc admin trace --all --verbose myminio
|
|
```
|
|
|
|
|
|
### On-board Diagnostics
|
|
On-board diagnostics help ensure that the underlying infrastructure that runs MinIO is configured correctly, and is functioning properly. This test is one-shot long running one, that is recommended to be run as soon as the cluster is first provisioned, and each time a failure scenrio is encountered. Note that the test incurs majority of the available resources on the system. Care must be taken when using this to debug failure scenario, so as to prevent larger outages. OBD tests can be triggered using [`mc admin obd`](https://github.com/minio/mc/blob/master/docs/minio-admin-complete-guide.md#command-obd---display-minio-server-obd) command.
|
|
|
|
Example:
|
|
```sh
|
|
minio server /data
|
|
```
|
|
|
|
The command takes no flags
|
|
```sh
|
|
mc admin obd myminio
|
|
```
|
|
|
|
The output printed will be of the form
|
|
```sh
