OpenDAL Observability Layer
This module offers essential components to facilitate the implementation of observability in OpenDAL.
§Prometheus Metrics
These metrics are essential for understanding the behavior and performance of our applications.
| Metric Name | Type | Description | Labels |
|---|---|---|---|
| operation_duration_seconds | Histogram | Histogram of time spent during opendal operations | scheme, namespace, root, operation, path |
| operation_bytes. | Histogram | Histogram of the bytes transferred during opendal operations | scheme, operation, root, operation, path |
| operation_errors_total | Counter | Error counter during opendal operations | scheme, operation, root, operation, path, error |
