Checklist

  • Reviewed the CONTRIBUTING.md guide (required)
  • Documentation added
  • Tests updated
  • Title matches the required conventional commits format, see here
    • Note that Promtail is considered to be feature complete, and future development for logs collection will be in Grafana Alloy. As such, feat PRs are unlikely to be accepted unless a case can be made for the feature actually being a bug fix to existing behavior.
  • Changes that require user attention or interaction to upgrade are documented in docs/sources/setup/upgrade/_index.md
  • For Helm chart changes bump the Helm chart version in production/helm/loki/Chart.yaml and update production/helm/loki/CHANGELOG.md and production/helm/loki/README.md. Example PR
  • If the change is deprecating or removing a configuration option, update the deprecated-config.yaml and deleted-config.yaml files respectively in the tools/deprecated-config-checker directory. Example PR

…rrect gap calculation (#13116)

 In summary, the Meta(now in loki/pkg/storage/stores/shipper/bloomshipper/client.go) structure contains a Sources []tsdb.SingleTenantTSDBIdentifier field, and within tsdb.SingleTenantTSDBIdentifier, there is an exportTSInSecs field. When Meta is serialized and written to OSS storage, the exportTSInSecs field is being set to its default value, false, which is not the expected behavior. It should retain its actual value; otherwise, this will lead to issues during subsequent gap calculations.
