Dashboards

All dashboards are provisioned automatically. Open Grafana at http://localhost:3000 (admin / admin).

Key dashboards

Dashboard What it shows
Tempo Chain Block height, block time, peers, txpool, RPC latency, resources. Use the Job/Instance dropdowns to filter.
Validator Health Consensus layer: epoch state, DKG peers, voting rates, consensus latency histograms.
RPC & Traefik RPC call rates and latency alongside Traefik request rate, response codes, and active connections.
Faucet tempo_fundAddress call rate/latency/errors and faucet pathUSD balance.

Logs

Navigate to Explore > Loki and query by container:

{container="tempo-validator-0"}
{container="tempo-faucet"} |= "error"

Traces

Navigate to Explore > Tempo. Traefik propagates the W3C traceparent header to RPC backends, so each request produces an end-to-end trace from the HTTP edge through the execution engine.

Profiling

Profiling requires a Tempo image built with the profiling profile and extra features. From the tempo repo, first build the chef (dependency) stage, then the final image:

# 1. Build the chef stage
docker build \
  --build-arg RUST_PROFILE=profiling \
  --build-arg RUST_FEATURES="asm-keccak,jemalloc-prof,jemalloc-symbols,otlp,tracy" \
  --build-arg EXTRA_RUSTFLAGS="-C force-frame-pointers=yes" \
  --target builder \
  -t tempo-chef:profiling \
  -f Dockerfile.chef .

# 2. Build the tempo image
docker build \
  --build-arg CHEF_IMAGE=tempo-chef:profiling \
  --build-arg RUST_PROFILE=profiling \
  --build-arg RUST_FEATURES="asm-keccak,jemalloc-prof,jemalloc-symbols,otlp,tracy" \
  --build-arg EXTRA_RUSTFLAGS="-C force-frame-pointers=yes" \
  --target tempo \
  -t tempo:profiling \
  -f Dockerfile .

Navigate to Explore > Pyroscope and select a service to view eBPF CPU profiles and pprof heap profiles.
