# Metrics Version 3
In metrics version 3, all metrics are available under the endpoint:
```
/minio/metrics/v3
```
however, a specific path under this is required.
Metrics are organized into groups at paths **relative** to the top-level endpoint above.
## Metrics Request Handling
Each endpoint below can be queried at different intervals as needed via a scrape configuration in Prometheus or a compatible metrics collection tool.
For ease of configuration, each (non-empty) parent of the path serves all metric endpoints that are at descendant paths. For example, to query all system metrics one needs to only scrape `/minio/metrics/v3/system/`.
Some metrics are bucket specific. These will have a `/bucket` component in their path. As the number of buckets can be large, the metrics scrape operation needs to be provided with a specific list of buckets via the `bucket` query parameter. Only metrics for the given buckets will be returned (with the bucket label set). For example to query API metrics for buckets `test1` and `test2`, make a scrape request to `/minio/metrics/v3/api/bucket?buckets=test1,test2`.
Instead of a metrics scrape, it is also possible to list the metrics that would be returned by a path. This is done by adding a `?list` query parameter. The MinIO server will then list all possible metrics that could be returned. During an actual metrics scrape, only available metrics are returned - not all of them. With the `list` query parameter, the output format can be selected - just set the request `Content-Type` to `application/json` for JSON output, or `text/plain` for a simple markdown formatted table. The latter is the default.
## Request, System and Cluster Metrics
At a high level metrics are grouped into three categories, listed in the following sub-sections. The path in each of the tables is relative to the top-level endpoint.
### Request metrics
These are metrics about requests served by the (current) node.
| Path | Description |
|-----------------|--------------------------------------------------|
| `/api/requests` | Metrics over all requests |
| `/bucket/api` | Metrics over all requests for a given bucket |
| | |
### Audit metrics

| Path | Description |
|----------|----------------------------------------|
| `/audit` | Metrics related to audit functionality |
### ILM metrics
These are metrics about the minio ILM functionality
| Path | Description |
|--------|--------------------------------------|
| `/ilm` | Metrics related to ILM functionality |
### Logger webhook metrics

| `/logger/webhook` | Metrics related to logger webhooks |
### Notification metrics

| `/notification` | Metrics related to notification functionality |
### Scanner metrics
These are metrics about the minio scanner
| Path | Description |

### System metrics
These are metrics about the minio process and the node.
| Path | Description |

| `/system/drive` | Metrics about drives on the system |
| `/system/memory` | Metrics about memory on the system |
| `/system/network/internode` | Metrics about internode requests made by the node |

| | |
### Debug metrics
These are metrics for debugging
| Path | Description |
|-----------------------------|---------------------------------------------------|
| `/debug/go` | Standard Go lang metrics |
| | |
### Cluster metrics
These present metrics about the whole MinIO cluster.
| Path | Description |
|--------------------------|-----------------------------|
| `/cluster/health` | Cluster health metrics |
| `/cluster/usage/objects` | Object statistics |
| `/cluster/usage/buckets` | Object statistics by bucket |
| `/cluster/erasure-set` | Erasure set metrics |
| | |
## Metrics Listing
Each of the following sub-sections list metrics returned by each of the endpoints.
The standard metrics group for GoCollector is not shown below.
