Using Python MockServer for API Testing

Using a mock server is a popular method of working around these limitations and realities, allowing you to test web server assets against specific requests, ensuring that your response data matches the expected outcome. Today, we’re going to look at a powerful solution for Python clients in the form of MockServer. We’ll walk through the tool’s basics and learn how to use it for your own testing.

Why Monitoring as Code Is the Future of Application Reliability for Modern Teams... and how it can save you $1 million!

I recently talked to a customer of Checkly and he shared some thoughts about Monitoring as Code. Let’s call him Karl in this article. Karl and I talked about why Monitoring as Code (MaC) is becoming essential for teams operating at scale. As the Head of Platform Engineering at a major e-commerce company processing millions of transactions daily, his experience shows how MaC solves a lot of the messy challenges that come with traditional synthetic monitoring setups.

How API Monitoring relates to tracking your health & stocks #APIMonitoring #Observability #ipm

In our everyday lives, people monitor various aspects like heart rate, step count, and stock performance to detect any unusual changes. The same concept applies to API monitoring. By continuously tracking and collecting measurements, teams can establish benchmarks and quickly identify deviations from the norm. This proactive approach helps detect and resolve issues, ensuring services perform at their expected level.

Intro to proxymock, a free traffic-based service mocking tool within VS Code.

Speedscale's proxymock is a free VS Code plugin that passively listens to transactions, so developers can replay past responses or inbound transactions like a time machine. Past transactions can serve as non-rate-limited service mocks, editable databases, or even regression/load/chaos tests. Building service mocks to serve as service virtualization/mocks can be time consuming and manual. Maintaining complex, shared environments for engineering incurs expensive cloud costs and aren't often accurate.

Ultimate Guide to Creating a JSON Mock API for Testing

Using a JSON mock allows you to avoid using fake data or simulating interactions, resulting in better final output and stronger data flows. Today, we’re going to dive into the process of creating a mock API using JSON data and tools like JSON-server. This guide will help you understand the basics of this process and get started quickly with your own mock API, allowing you to speed up development and testing without relying on a live backend.

What Is API Monitoring?

Application programming interfaces (APIs) are the James Bonds of software, silently keeping everything running smoothly while sipping martinis (shaken, not stirred). They’re the vital communication channels that enable different software systems to interact seamlessly, making sure your online shopping carts don’t mysteriously empty and your social media feeds keep you endlessly entertained with cat videos.

Stay ahead of service disruptions with Watchdog Cloud & API Outage Detection

Even with the best monitoring in place, outages are unavoidable. Complex, modern IT environments rely on multiple third-party services, including critical cloud and API providers, and when any one of those goes down, it can trigger a domino effect of increased error rates and latency spikes across your system. And, because you don’t have as much visibility into external services, it can be difficult to identify that the problem is due to an outside outage or disrupted service.

Understanding API Keys and Tokens: Secure Management and Best Practices

APIs (Application Programming Interfaces) are the foundation of applications, facilitating communication between different services. To authenticate and secure these interactions, API keys and tokens play a vital role. However, improperly managing these sensitive credentials can lead to security vulnerabilities. In this blog, we will explore what API keys and tokens are, how to securely manage them, and best practices to use them across services while avoiding exposure.

Python Observability : A Complete Guide

Observability is a critical element of modern software development, unlocking awareness across complex and distributed systems with ease. This has allowed developers to monitor, understand, and debug their applications effectively, leveraging existing resources for more efficient lifecycle management and iteration. In the context of Python, observability is an engine for boosting and maintaining the performance, reliability, and stability of the implementation. In this guide, we're going to look at the key aspects of building and deploying Python observability, the importance of this process, and the tools available to implement it.

Orchestrated Service Virtualization: The Definitive Guide

Software development requires a lot of things to be highly optimized due to the sheer number of parts and the interconnected nature of those parts. Making your service seamless, efficient, and scalable requires tooling that is itself seamless, efficient, and scalable. As organizations have moved to adopting microservices and distributed cloud-native solutions, being able to effectively scale resources and the systems which operate upon those resources has been made even more critical.

What is Traffic Mirroring: A Complete Guide

Ensuring seamless data flow and robust application performance is crucial in modern networking and cloud computing. Traffic mirroring enables enhanced network observability, allows for effective troubleshooting, and facilitates the testing of new features without interrupting live traffic. It captures and replicates network traffic, providing a powerful solution for maintaining and optimizing network operations.

The Ultimate Guide to API Monitoring in 2025 - Metrics, Tools, and Proven Practices

According to Akamai, 83% of web traffic is through APIs. Microservices, servers, and clients constantly communicate to exchange information. Even the Google search you made to reach this article involved your browser client calling Google APIs. Given APIs govern the internet, businesses rely on them heavily. API health is directly proportional to business prosperity. This article covers everything about API monitoring, so your API infrastructure’s health is always in check .

What does OOMKilled mean and how do I prevent it?

When creating production-level applications, enterprises want to ensure the high availability of services. This often results in a lengthy development process that requires extensive testing for the applications or a new release. This involves testing the behavior of the application under load, measuring the performance metrics, and accounting for the resource consumption. All this is done to ensure that the application does not behave unexpectedly when being used by clients.
