Altona testnet

• Spec version: v0.12.1
• Circa 120_000 slots filled with circa 90% blocks at start time
• 4 different clients known to validate the network
• 5 different clients known to connect and sync the network
• Permalink: https://github.com/goerli/altona/tree/a8f16766040710af30a03ce59d74bfca282ca78b

Metrics collected

• time: Unix time in seconds
  • all: (Ruby) Time.now.to_i
• db: Database size in bytes
  • Lighthouse: (Shell) du -bs $HOME/.lighthouse/beacon/chain_db/
  • Prysm: (Shell) du -bs $HOME/.eth2/beaconchaindata/
  • Teku: (Shell) du -bs $HOME/.local/share/teku/data/db/
• mem: Resident memory in bytes
  • Lighthouse: (REST API) /node/health, .pid_mem_resident_set_size
  • Prysm: (Metrics) process_resident_memory_bytes
  • Teku: (Metrics) process_resident_memory_bytes
• slot: Head slot number in 1
  • Lighthouse: (REST API) /beacon/head, .slot
  • Prysm: (gRPC API) /eth/v1alpha1/beacon/chainhead, .headSlot
  • Teku: (REST API) /beacon/head, .slot
• bps: Slot sync each second in 1/second (*)
  • all: (Ruby) (h.to_f - prev_h.to_f) / dt
• peers: Peer count in 1
  • Lighthouse: (REST API) /network/peer_count
  • Prysm: (gRPC API) /eth/v1alpha1/node/peers (counted)
  • Teku: (REST API) /network/peer_count

*) Note, due to different ways of processing incoming badges of blocks, this metric should be recomputed based on an average taken over 60 seconds.

Metrics derived (TBD)

• Slot sync speed over time (moving average)
• Database size over sync time
• Database size over slot count (future projection: 1Y, 5Y)
• Resident memory usage over sync time
• Resident memory usage over time augmented with chain finality (external data)
