# 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 is on always and cannot be disabled.
|
|
|
|
### 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/ logger_webhook
|
|
logger_webhook:name1 auth_token="" endpoint=""
|
|
```
|
|
|
|
```
|
|
mc admin config set myminio logger_webhook:name1 auth_token="" endpoint="http://endpoint:port/path"
|
|
mc admin service restart myminio
|
|
```
|
|
|
|
NOTE: `http://endpoint:port/path` is a placeholder value to indicate the URL format, please change this accordingly as per your configuration.
|
|
|
|
MinIO also honors environment variable for HTTP target logging as shown below, this setting will override the endpoint settings in the MinIO server config.
|
|
```
|
|
export MINIO_LOGGER_WEBHOOK_ENABLE_target1="on"
|
|
export MINIO_LOGGER_WEBHOOK_AUTH_TOKEN_target1="token"
|
|
export MINIO_LOGGER_WEBHOOK_ENDPOINT_target1=http://localhost:8080/minio/logs
|
|
minio server /mnt/data
|
|
```
|
|
|
|
## Audit Targets
|
|
Assuming `mc` is already [configured](https://docs.min.io/docs/minio-client-quickstart-guide.html)
|
|
```
|
|
mc admin config get myminio/ audit_webhook
|
|
audit_webhook:name1 enable=off endpoint= auth_token= client_cert= client_key=
|
|
```
|
|
|
|
```
|
|
mc admin config set myminio audit_webhook:name1 auth_token="" endpoint="http://endpoint:port/path"
|
|
mc admin service restart myminio
|
|
```
|
|
|
|
NOTE: `http://endpoint:port/path` is a placeholder value to indicate the URL format, please change this accordingly as per your configuration.
|
|
|
|
MinIO also honors environment variable for HTTP target Audit logging as shown below, this setting will override the endpoint settings in the MinIO server config.
|
|
```
|
|
export MINIO_AUDIT_WEBHOOK_ENABLE_target1="on"
|
|
export MINIO_AUDIT_WEBHOOK_AUTH_TOKEN_target1="token"
|
|
export MINIO_AUDIT_WEBHOOK_ENDPOINT_target1=http://localhost:8080/minio/logs
|
|
export MINIO_AUDIT_WEBHOOK_CLIENT_CERT="/tmp/cert.pem"
|
|
export MINIO_AUDIT_WEBHOOK_CLIENT_KEY=="/tmp/key.pem"
|
|
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.
|
|
|
|
NOTE:
|
|
- `timeToFirstByte` and `timeToResponse` will be expressed in Nanoseconds.
|
|
- Additionally in the case of the erasure coded setup `tags.objectErasureMap` provides per object details about
|
|
- Pool number the object operation was performed on.
|
|
- Set number the object operation was performed on.
|
|
- The list of disks participating in this operation belong to the set.
