From 219f327ec81650cbee3b3adec588bc37c9d0dfc6 Mon Sep 17 00:00:00 2001 From: Sally MacFarlane Date: Tue, 17 Feb 2026 10:28:03 +1000 Subject: [PATCH 01/44] Add cross-client execution metrics and slow block logging Implements standardized execution metrics collection for block processing performance monitoring, following the cross-client execution metrics specification. Key features: - SlowBlockTracer: logs detailed JSON metrics for blocks exceeding a configurable threshold (--slow-block-threshold CLI flag or -Dbesu.execution.slowBlockThresholdMs) - StateMetricsCollector: instance-based metrics collection threaded through the world state object graph, replacing ThreadLocal-based approaches - ExecutionStats: tracks timing breakdowns, state access counts, cache performance, and EVM operation counts (SLOAD, SSTORE, CALL, CREATE) - BlockAwareTracerAggregator: composable tracer pattern for combining multiple block-aware operation tracers - ExecutionMetricsTracer: EVM-level tracer for opcode counting - Parallel execution support with metrics aggregation across background threads Co-authored-by: CPerezz Signed-off-by: Sally MacFarlane --- CHANGELOG.md | 4 +- .../SlowBlockMetricsValidationTest.java | 314 ++++++ .../slowblock/model/ExpectedMetrics.java | 327 +++++++ .../slowblock/model/TaggedBlock.java | 457 +++++++++ .../slowblock/model/TransactionType.java | 72 ++ .../SlowBlockMetricsReportGenerator.java | 661 +++++++++++++ .../org/hyperledger/besu/cli/BesuCommand.java | 10 +- .../besu/cli/options/MetricsOptions.java | 37 +- .../services/BlockSimulatorServiceImpl.java | 7 +- app/src/test/resources/everything_config.toml | 5 +- .../mainnet/AbstractBlockProcessor.java | 23 +- .../mainnet/BlockAwareTracerAggregator.java | 280 ++++++ .../mainnet/ExecutionMetricsTracer.java | 185 ++++ .../besu/ethereum/mainnet/ExecutionStats.java | 911 ++++++++++++++++++ .../mainnet/ExecutionStatsHolder.java | 65 ++ .../ethereum/mainnet/SlowBlockTracer.java | 437 +++++++++ .../BalConcurrentTransactionProcessor.java | 21 +- .../ParallelTransactionPreprocessing.java | 10 +- ...lelizedConcurrentTransactionProcessor.java | 194 +++- .../ParallelizedTransactionContext.java | 33 +- .../transaction/BlockSimulationParameter.java | 52 +- .../transaction/BlockSimulationResult.java | 21 + .../ethereum/transaction/BlockSimulator.java | 48 +- .../BlockStateCallSimulationResult.java | 10 + .../cache/BonsaiCachedMerkleTrieLoader.java | 29 +- .../pathbased/common/PathBasedAccount.java | 11 + .../common/worldview/PathBasedWorldState.java | 27 + .../common/worldview/PathBasedWorldView.java | 9 + .../worldview/StateMetricsCollector.java | 69 ++ .../PathBasedWorldStateUpdateAccumulator.java | 13 +- .../ExecutionStatsIntegrationTest.java | 857 ++++++++++++++++ ...ParallelBlockTransactionProcessorTest.java | 14 +- .../TransactionCollisionDetectorTest.java | 19 +- .../EthTransferLogOperationTracer.java | 1 + .../evm/tracing/ExecutionMetricsTracer.java | 208 ++++ .../besu/evm/tracing/OperationTracer.java | 10 + .../besu/metrics/BesuMetricCategory.java | 2 +- .../prometheus/MetricsConfiguration.java | 36 +- 38 files changed, 5413 insertions(+), 76 deletions(-) create mode 100644 acceptance-tests/tests/src/acceptanceTest/java/org/hyperledger/besu/tests/acceptance/SlowBlockMetricsValidationTest.java create mode 100644 acceptance-tests/tests/src/acceptanceTest/java/org/hyperledger/besu/tests/acceptance/slowblock/model/ExpectedMetrics.java create mode 100644 acceptance-tests/tests/src/acceptanceTest/java/org/hyperledger/besu/tests/acceptance/slowblock/model/TaggedBlock.java create mode 100644 acceptance-tests/tests/src/acceptanceTest/java/org/hyperledger/besu/tests/acceptance/slowblock/model/TransactionType.java create mode 100644 acceptance-tests/tests/src/acceptanceTest/java/org/hyperledger/besu/tests/acceptance/slowblock/report/SlowBlockMetricsReportGenerator.java create mode 100644 ethereum/core/src/main/java/org/hyperledger/besu/ethereum/mainnet/BlockAwareTracerAggregator.java create mode 100644 ethereum/core/src/main/java/org/hyperledger/besu/ethereum/mainnet/ExecutionMetricsTracer.java create mode 100644 ethereum/core/src/main/java/org/hyperledger/besu/ethereum/mainnet/ExecutionStats.java create mode 100644 ethereum/core/src/main/java/org/hyperledger/besu/ethereum/mainnet/ExecutionStatsHolder.java create mode 100644 ethereum/core/src/main/java/org/hyperledger/besu/ethereum/mainnet/SlowBlockTracer.java create mode 100644 ethereum/core/src/main/java/org/hyperledger/besu/ethereum/trie/pathbased/common/worldview/StateMetricsCollector.java create mode 100644 ethereum/core/src/test/java/org/hyperledger/besu/ethereum/mainnet/ExecutionStatsIntegrationTest.java create mode 100644 evm/src/main/java/org/hyperledger/besu/evm/tracing/ExecutionMetricsTracer.java diff --git a/CHANGELOG.md b/CHANGELOG.md index 15909cfbe41..a7e72fd0f7a 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -40,13 +40,14 @@ - Add ability to pass a custom tracer to block simulation [#9708](https://github.com/hyperledger/besu/pull/9708) - Add support for `4byteTracer` in `debug_trace*` methods to collect function selectors from internal calls via PR [#9642](https://github.com/hyperledger/besu/pull/9642).

When enabled, blocks whose execution time exceeds the threshold are logged in a structured JSON format covering timing breakdowns, state reads/writes, cache hit rates, and EVM opcode counts, following the cross-client execution metrics specification. Disabled by default; set `--slow-block-threshold=` to enable (0 logs all blocks).
