Release Notes

grafana/gcx (aqua:grafana/gcx)

v1.4.0

Compare Source

Metrics and traces

• Add gcx metrics search metric-names/label-names/label-values and
  gcx datasources prometheus search-metric-names/search-label-names/search-label-values,
  backed by the experimental Prometheus/Mimir search API (#​1374)
• Add experimental TraceByID options to gcx traces get and
  gcx datasources tempo get: --filter keeps the spans that match a TraceQL
  spanset expression, shaped by --keep-hierarchy, --match-depth and
  --ancestor-depth; --prune (with --prune-group-by, --prune-min-spans,
  --prune-max-parent-depth) collapses repeated sibling spans. Both are off
  unless set, and aim at shrinking large traces before --llm analysis (#​1250)

Authentication and configuration

• Add Basic authentication to gcx login (#​1389)
• List the available contexts when the requested context is not found (#​1210)

Agent Observability

• Add gcx agento11y model-rates to set your own negotiated model prices (#​1377)

Synthetic Monitoring and IRM

Security and debugging

• --insecure-log-http-payload dumps now run at the innermost transport layer
  and show every header that reaches the wire, including the OAuth bearer
  token. They also show the OAuth token refresh exchange, which carries the
  refresh token and the rotated token pair. Treat captured debug logs as
  secrets (#​1190)
• Label the dumps http request dump and http response dump, include
  Content-Length and Accept-Encoding in request dumps, report why a dump
  failed, and document that dumps log at Debug level (-vvv) (#​1190)

Docs and internals

• Add guides for managing resources and diagnosing missing telemetry
  (#​1413, #​1368)
• Clarify the MkDocs setup and fix broken links (#​1378, #​1417)
