Queries now run through the Go backend against GreptimeDB (/v1/sql), which enables Grafana Alerting.

Features

  • Time macros ($__timeFilter, $__fromTime, $__toTime, $__timeInterval, $__interval) are expanded in Go with GreptimeDB SQL (date_bin).
  • Backend response shaping covers time series multi-frame, logs, and traces.
  • Enable Use OTel to auto-fill GreptimeDB-style Logs/Traces columns; otherwise map columns manually.
  • OTel version selection is available again in datasource settings and the Logs/Traces builders.
  • Ad-hoc filters inject into Query Builder panels as standard WHERE (SQL Editor is unchanged); cross-table filters are scoped by table.column.
  • Public releases ship info8fcc-greptimedb-datasource-unsigned.zip only (allow_loading_unsigned_plugins = info8fcc-greptimedb-datasource).
  • Built-in demos: GreptimeDB - OTel Min Demo and GenAI Observability.

Fixes

  • Quote reserved identifiers such as timestamp in macros and generated SQL.
  • Improve trace attribute/status mapping for the Grafana waterfall.
  • Skip ad-hoc filters that target a different table than the panel query.
  • Apply OTel preset columns correctly on first load of Logs/Traces builders.
  • Show View logs on trace ID cells only when a default logs table is configured.
  • Fix LIMIT handling in Query Builder SQL generation.
