Quickly measure and assess the latency from your server to the arbitrum sequencer.

Delay Arb Checker

This README was written with the assistance of ChatGPT.

Overview

The Delay Arb Checker is a tool designed to measure the latency of a service by performing repeated tests to an EVM RPC endpoint. It offers a straightforward way to monitor and analyze the response times of your RPC endpoints, which is critical for performance tuning and service health monitoring.

Features

• Perform latency tests against a specified RPC URL.
• Customize the number of test iterations with ease.
• Simple command-line interface for easy integration into monitoring systems.

Getting Started

Prerequisites

Before using the Delay Arb Checker, ensure you have:

• A system with command-line access.
• Network access to the RPC endpoint you wish to test.

Download

To begin using the Delay Arb Checker, download the latest version directly from the GitHub releases:

1. Visit the latest release page for the Delay Arb Checker project.
2. Download the checker binary suitable for your operating system.
3. Make sure to set the downloaded binary as executable. For Unix-like systems, you can use chmod +x checker.

curl -o checker https://github.com/tangtj/DelayArbChecker/releases/download/latest/checker

chmod +x checker

Usage

To use the tool, open a command prompt or terminal.

Execute the application with the following options:

./checker -url <rpc-url> -t <number-of-tests>

• -url specifies the RPC URL you want to test; the default is "https://arb1-sequencer.arbitrum.io/rpc".
• -t sets the number of latency tests to perform. If not specified, the default is 20.

Example command:

./checker -url https://arb1-sequencer.arbitrum.io/rpc -t 20

This will perform 20 latency tests against the specified Arbitrum RPC endpoint.
