Troubleshoot your tests

Article Summary

Reliable load tests require solid preparation, controlled smoke testing, and structured error analysis.
Validation and smoke tests help detect script issues early and establish trustworthy baseline response times.
The guide explains how to identify common problems such as missing agents, premature test stops, and overloaded load generators.
It details how to distinguish script errors from server-side failures using response codes, error rates, and logs.
Clear troubleshooting patterns make it easier to isolate root causes and avoid misleading performance conclusions.

OctoPerf MCP Server

Summary

The rise of MCP is reshaping how AI interacts with technical tools, and this project shows how an MCP server can let AI assistants operate OctoPerf directly.
The goal is to make performance testing more accessible: running tests, analyzing results, and generating insights through natural language.
Built as an MVP, the server demonstrates how AI can automate workflows that normally require manual navigation and correlation.
The project highlights MCP’s key concepts, the supporting Go framework, and how developers can extend the system with new tools and analyses.
A demo illustrates end-to-end usage, from listing workspaces to running tests and comparing results.
The experience confirms how MCP can bridge AI and APIs to create smarter, more productive performance-testing workflows.
