As part of normal operation, CockroachDB continuously records metrics that track performance, latency, usage, and many other runtime indicators. These metrics are often useful in diagnosing problems, troubleshooting performance, or planning cluster infrastructure modifications. This page documents locations where metrics are exposed for analysis.
## Available metrics
| Name | Description |
| ------------------------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `addsstable.applications` | Number of SSTable ingestions applied (i.e., applied by Replicas) |

| `changefeed.aggregator_progress` | The earliest timestamp up to which any [aggregator](how-does-an-enterprise-changefeed-work) is guaranteed to have emitted all values for which it is responsible. **Note:** This metric may regress when a changefeed restarts due to a transient error. Consider tracking the `changefeed.checkpoint_progress` metric, which will not regress. |

This is calculated based on the cluster settings: - [`changefeed.lagging_ranges_threshold`](advanced-changefeed-configuration#lagging-ranges), which is the amount of time that a range checkpoint needs to be in the past to be considered lagging.
