If you’re diving into the world of blockchain performance testing, Hyperledger Caliper is your trusted ally. With its robust framework for benchmarking various blockchain networks, Caliper simplifies the process of evaluating performance metrics. This guide walks you through how to effectively use the Caliper benchmarks and troubleshoot any issues that may arise along the way.

What You Need to Get Started

Before you can delve into the benchmarks offered in this repository, you need to ensure you have Hyperledger Caliper set up properly. Follow these basic steps:

• Install the Caliper CLI from the Caliper main repository.
• Clone the benchmark repository.
• Run a Caliper CLI command that targets one of the benchmarks in the repository.

Understanding the Repository Structure

The benchmarks are organized in a structured manner to facilitate ease of use. Think of it like a library where books are arranged by genres. Here’s the breakdown:

• Main Branch: This contains sample benchmarks.
• Reports Branch: It consists of markdown files that are generated and published.
• gh-pages Branch: Here lies the static content built from the reports.

Diving Deeper: The Main Branch Contents

Inside the main branch, the benchmarks are further classified into three directories:

• Benchmarks: Similar to a cookbook, this area contains recipe-like test configuration and callback files that guide the benchmark tests.
• api: Tests directed towards the API of a single target blockchain.
• samples: Tests for the native samples provided by blockchain platforms.
• scenario: Generic scenarios applicable across supported blockchain platforms.
• Networks: Think of this as a showcase of sample blockchain networks available for benchmarking.
• Src: This directory holds the source smart contracts that interact with the test callbacks. Each smart contract has its own folder, organized by the corresponding blockchain technology.

Running a Benchmark

To run any benchmark, ensure that Hyperledger Caliper is rightly installed. Here are the overall steps you’ll need to follow:

1. Set up the Caliper CLI by following the instructions in the Caliper main repository.
2. Clone this benchmark repository.
3. Execute a Caliper CLI command that targets your desired benchmark.

For additional guidance, specific instructions are available for working with Hyperledger Fabric and Hyperledger Besu. Check out their respective documentation for thorough insights.

Troubleshooting

While it’s straightforward to get started with Hyperledger Caliper, you might encounter some hiccups. Here are a few troubleshooting tips:

• Ensure that your installation of Caliper is up to date.
• Check if the target benchmark file path is correct during a CLI command.
• If you’re using specific blockchain networks, verify that the required smart contracts are deployed before running the benchmark.
• Consult the logs for any error messages that may guide you towards a solution.
