# MinIO Logging Quickstart Guide [](https://slack.min.io)
|
|
This document explains how to configure MinIO server to log to different logging targets.
|
|
|
|
## Log Targets
|
|
MinIO supports currently two target types
|
|
|
|
- console
|
|
- http
|
|
|
|
### Console Target
|
|
Console target logs to `/dev/stderr` and is enabled by default. To turn-off console logging you would have to update your MinIO server configuration using `mc admin config set` command.
|
|
|
|
Assuming `mc` is already [configured](https://docs.min.io/docs/minio-client-quickstart-guide.html)
|
|
```
|
|
mc admin config get myminio/ > /tmp/config
|
|
```
|
|
|
|
Edit the `/tmp/config` and toggle `console` field `enabled` from `true` to `false`.
|
|
|
|
```json
|
|
"logger": {
|
|
"console": {
|
|
"enabled": false
|
|
}
|
|
},
|
|
```
|
|
|
|
Once changed, now you may set the changed config to server through following commands.
|
|
```
|
|
mc admin config set myminio/ < /tmp/config
|
|
mc admin restart myminio/
|
|
```
|
|
|
|
### HTTP Target
|
|
HTTP target logs to a generic HTTP endpoint in JSON format and is not enabled by default. To enable HTTP target logging you would have to update your MinIO server configuration using `mc admin config set` command.
|
|
|
|
Assuming `mc` is already [configured](https://docs.min.io/docs/minio-client-quickstart-guide.html)
|
|
```
|
|
mc admin config get myminio/ > /tmp/config
|
|
```
|
|
|
|
Edit the `/tmp/config` and toggle `http` field `enabled` from `false` to `true`.
|
|
```json
|
|
"logger": {
|
|
"console": {
|
|
"enabled": false
|
|
},
|
|
"http": {
|
|
"1": {
|
|
"enabled": true,
|
|
"endpoint": "http://endpoint:port/path"
|
|
}
|
|
}
|
|
},
|
|
```
|
|
NOTE: `http://endpoint:port/path` is a placeholder value to indicate the URL format, please change this accordingly as per your configuration.
|
|
|
|
Once changed, now you may set the changed config to server through following commands.
|
|
```
|
|
mc admin config set myminio/ < /tmp/config
|
|
mc admin restart myminio/
|
|
```
|
|
|
|
MinIO also honors environment variable for HTTP target logging as shown below, this setting will override the endpoint settings in the MinIO server config.
|
|
```
|
|
MINIO_LOGGER_HTTP_ENDPOINT=http://localhost:8080/minio/logs minio server /mnt/data
|
|
```
|
|
|
|
## Audit Targets
|
|
For audit logging MinIO supports only HTTP target type for now. Audit logging is currently only available through environment variable.
|
|
```
|
|
MINIO_AUDIT_LOGGER_HTTP_ENDPOINT=http://localhost:8080/minio/logs/audit minio server /mnt/data
|
|
```
|
|
|
|
Setting this environment variable automatically enables audit logging to the HTTP target. The audit logging is in JSON format as described below.
|
