Metrics

Build

Constant gauge (value 1) carrying the running application’s identity in its tag set. Tags: name, version.

Name: korvet.application.build
Type: gauge

Table 1. Tags
Key	Description
`name`	Application name (typically `korvet`).
`version`	Application version as reported by Spring Boot `BuildProperties`; `unknown` when the build did not embed `build-info.properties`.

Lag

Total lag (sum of the known per-partition lags) for one consumer group, sampled server-side on korvet.broker.metrics.group-lag-refresh-interval. Reads NaN while the group’s offsets cannot be determined, so scrapes record a gap rather than a fabricated zero. Tags: group.

Name: korvet.group.lag
Type: gauge

Table 2. Tags
Key	Description
`group`	Consumer group id. Cardinality is bounded by `korvet.broker.metrics.group-lag-cardinality-cap`.
