2 things to look at

  • no licenseNo license file was found in the repository. Code published without one is not open source by default, so using it at work is a question for whoever answers licensing questions where you are.
  • 5 stars5 stars. Stars are a popularity signal and not a quality one, but at this level it is likely that nobody has read this closely except its author, and you would be relying on your own review.

Latency Tracker

Per-call and aggregated latency tracking for MEV infrastructure.

When to Use

  • Implementing performance monitoring
  • Debugging slow operations
  • Adding instrumentation to code paths
  • Tracking end-to-end latency
  • Setting up alerting thresholds

Workflow

Step 1: Define Span Hierarchy

Structure spans from e2e_flow down to individual calls.

Step 2: Instrument Code

Wrap operations in tracker.span() calls.

Step 3: Set Alert Thresholds

Configure alerts for latency exceeding expected ranges.


Span Hierarchy

e2e_flow (root) ├── rust_hotpath_call (5-15ms) │ └── rpc_eth_call (5-20ms) ├── tx_submit └── tx_confirm (1-15s)

Usage

const e2e = tracker.startE2E('liq');

await e2e.span('rust_call', async () => {
  return await callRust();
});

e2e.complete({ success: true });

Alert Thresholds
