What

Re-enables Tempo metrics generator and delivers a full suite of Pi agent telemetry dashboards.

Infrastructure Changes

  • Tempo: Enable metricsGenerator with remote_write to Prometheus
  • kube-prometheus-stack: Enable --enable-feature=remote-write-receiver on Prometheus

Dashboards

Dashboard UID Focus
Pi Sessions pi-sessions Session count, duration, tool calls, errors, trends
Pi Tools pi-tools Tool usage, duration, error traces
Pi LLM & Performance pi-llm-performance Turn counts, turn duration, LLM data
Agent Telemetry (fixed) agent-telemetry General overview with working queries

Query Types Used

  • TraceQL metrics (traceql): stat panels + time series — requires metrics generator
  • TraceQL search (traceqlSearch): tables + traces panels — works without metrics generator

Notes

  • Replaces broken queries in Agent Telemetry that referenced non-existent attributes (.plane.ticket_id, .user.id, .paperclip.run_id)
  • Previous metrics generator was removed in HOMELAB-1092 due to invalid overrides.defaults.metrics_generator nested object. This PR uses the helm chart's built-in metricsGenerator.enabled which generates the correct flat metrics_generator_processors key.

Closes HOMELAB-1096
