Metrics

Explorer metrics

Metric	Value	Means	Expect
`frontend_ex_cache_swr_entries`	`0`	Entries in the stale-while-revalidate cache.	small integer. 0 is OK.
`frontend_ex_cache_api_entries`	`0`	Entries in the explorer API cache.	small integer. 0 is OK on a quiet box.
`vm_memory_total_bytes`	`175.5 MiB`	BEAM memory for this explorer VM.	hundreds of MiB, not climbing without bound.

2d metrics

Metric	Value	Means	Expect
`chain_producer_blocks_total`	`1756`	Blocks this producer process has committed since boot.	rising. freeze = not mining (see stalled/idle).
`chain_producer_health_poll_ok`	`yes`	Last producer-health poll (the thing that writes these gauges) succeeded.	yes. no = gauges may be stale.
`chain_producer_tick_age_seconds`	`0.0 s`	Seconds since the last produce_block tick (even if it mined nothing).	under 10s on a 2s slot. 1e9 = never ticked this boot.
`chain_producer_idle`	`no`	Producer is ticking but the tip is older than 10s (empty mempool skips empty blocks).	no while gen_txs should be landing. yes = generator skip/empty, not a dead producer.
`chain_producer_stalled`	`no`	Producer tick is older than 10s — the GenServer is not looping.	no. yes = chain.service hung or not running.
`chain_latest_block_age_seconds`	`0.0 s`	Seconds since the tip block timestamp.	under 10s while traffic is flowing. 1e9 = no blocks.
`chain_latest_block_number`	`776074`	Highest history.blocks.number on this node.	monotonic, matching the explorer home tip.
`chain_pq_verifier_available`	`yes`	libmldsa65_verify.so is loaded so the producer can check enclave signatures before commit.	yes. no = armed producer fail-closes every block (2026-09-21 cutover).
`bridge_intent_watcher_last_tick_seconds`	`24.2 s`	Seconds since the last IntentWatcher tick.	under 60s (interval 30s). 1e9 = never ticked.
`bridge_intent_watcher_first_tick_completed`	`yes`	Watcher has completed at least one successful tick this boot.	yes after ~30s. no = watcher never started.
`bridge_intent_watcher_stall_ticks`	`0`	Consecutive failed watcher ticks on the same from_block.	0. ≥5 used to fire the stall alert.
`bridge_intent_watcher_cursor_lag_blocks`	`0`	ETH finalized head minus IntentWatcher cursor.	0. growing = getLogs/RPC stall (public dRPC 400).
`bridge_watchdog_tripped`	`no`	Bridge watchdog auto-halt fired this process lifetime.	no / 0.

tx generator metrics

Metric	Value	Means	Expect
`gen_txs_interval_ms`	`0`	Sleep between gen_txs submissions. 0 = as fast as RPC RTT.	0 on aya (pack toward ~100 TPS).
`gen_txs_max_inflight`	`20`	Unmined txs allowed per pool sender.	20 on aya with 100+100 pool.
`gen_txs_eth_pool`	`100`	eth_sendRawTransaction sender count.	100 on aya.
`gen_txs_tron_pool`	`100`	Tron protobuf sender count.	100 on aya.
`gen_txs_max_tx_raw`	`1`	Max raw USDC per transfer (1 recirculates dust).	1 on aya.
`gen_txs_log_every`	`1000`	Print one success line every N broadcasts.	1000 with --quiet.
`gen_txs_http_only`	`yes`	Generator is HTTP-only (no second chain supervision tree).	yes on aya.
`gen_txs_no_faucet`	`yes`	Generator will not mint; senders must already hold dust.	yes on aya.
`gen_txs_forever`	`yes`	Run until SIGTERM.	yes for 2d-tx-generator.service.
`gen_txs_agent`	`no`	Also POST /agent/v1/transfers (HSM SIGN_TRANSFER).	no until operator.agent_identities is populated.
`gen_txs_submitted_total{surface="eth"}`	`237725`	Successful broadcasts this boot, by surface (eth / tron / agent).	rising while the unit is packing blocks.
`gen_txs_submitted_total{surface="tron"}`	`237074`	Successful broadcasts this boot, by surface (eth / tron / agent).	rising while the unit is packing blocks.
`gen_txs_submitted_total{surface="agent"}`	`0`	Successful broadcasts this boot, by surface (eth / tron / agent).	rising while the unit is packing blocks.
`gen_txs_skip_total`	`12303`	Loops with no spendable sender (dust / inflight cap).	can rise; a freeze plus last-ok age growing means the pool is dry.
`gen_txs_inflight`	`3853`	Local unmined reservations still held.	under max-inflight × pool. 0 between blocks is OK.
`gen_txs_empty_streak`	`0`	Consecutive empty loops since the last successful broadcast.	0 while submitting. climbing = skip.
`gen_txs_last_ok_age_seconds`	`0.0 s`	Seconds since last successful gen_txs broadcast.	under 15s while packing. 1e9 = none this boot.

2d-hsm metrics

Metric	Value	Means	Expect
`chain_hsm_sign_ok_total`	`1756`	Successful host-side SIGN_BLOCK round-trips this boot.	rising while blocks land.
`chain_hsm_last_sign_ok_age_seconds`	`0.0 s`	Seconds since last successful SIGN_BLOCK on this 2d node.	small while producing. 1e9 = none this boot (OK if the producer is idle).
`chain_hsm_producer_socket_up`	`yes`	Host-side producer signer UDS exists (proxy to 2d-hsm). Not an in-enclave scrape.	yes when armed. no = SIGN_BLOCK cannot reach the enclave.
`chain_hsm_armed`	`yes`	This 2d node has PRODUCER_HSM_SIGNING_ARMED=true.	yes on aya. no = producer fail-closes once a producer is registered.

OPA metrics

Metric	Value	Means	Expect
`http_request_duration_seconds_count{code="200",handler="v1/data",method="get"}`	`3`	OPA HTTP requests to the policy Data API (v1/data). Not Go runtime.	v1/data POST 200 rising with bridge/gas-EOA decisions. 5xx = policy HTTP failure.
`http_request_duration_seconds_count{code="200",handler="v1/data",method="post"}`	`4`	OPA HTTP requests to the policy Data API (v1/data). Not Go runtime.	v1/data POST 200 rising with bridge/gas-EOA decisions. 5xx = policy HTTP failure.

Scrapes stay on loopback (2d /admin/metrics, explorer :9568, OPA :8181, gen_txs :4011). Generator falls back to 2d idle if that scrape is unset. 2d-hsm gauges are host-side from 2d (no in-enclave scrape). OPA shows HTTP policy (v1/data) only.
