Troubleshooting, Dynamic Logging, and Observability for .Net — A New Kid on the Block

Aggregated on: 2023-05-03 18:45:26

A few years in software development do not equate to a linear amount of knowledge and information. So is true for the .NET ecosystem. The first release of .NET 1.0 saw the light of day in January 2002. The significance of the event was not the palindrome year. The new paradigm is offered to the traditional C++ MFC, VB, and classic ASP developers, supporting two main new languages, C#, and VB.NET. It started as a proprietary Windows technology, closed source language, primarily appealing to the companies on Microsoft Windows stack, tied to the sole IDE, Visual Studio. While .NET was a step forward, the pace and the options outside the designated use were abysmal. The situation took a sharp turn, with a substantial change in 2016 with the introduction of .NET Core. Starting from the heart of the .NET ecosystem, ASP.NET, the change has spread through the entire platform, leading to a complete re-imagination and makeover of runtime and language. Open source, cross-platform, and free for commercial use, .NET and C# became viable options for many projects that traditionally would go with another platform and languages. From web to mobile, from desktop to backend systems, in any cloud environment, .NET is a solid and viable option with outstanding experience and rich offerings.

Consider the following sequence: Your car's "low fuel" indicator comes on As a result, you stop at the next fuel station to fill up When you pump gas into the car, you get prompted to join the company’s rewards club to get a discount You go inside and sign up and get a credit toward your next purchase We could go on and on here, but I've made my point: life is a sequence of events. Given that fact, how would you design a new software system today? Would you collect different results and process them at some arbitrary interval or wait until the end of the day to process them? No, you wouldn't; you'd want to act on each event as soon as it happens. Sure, there may be cases where you can't respond immediately to individual circumstances… think of getting a dump of a day’s worth of transactions at one time. But still, you would act as soon as you received the data, a sizeable lump-sum event if you will.

Prometheus AWS Exporter and Grafana

Aggregated on: 2023-05-01 21:15:25

The main purpose of this article and use case is to scrape AWS CloudWatch metrics into the Prometheus time series and to visualize the metrics data in Grafana. Prometheus and Grafana are the most powerful, robust open-source tools for monitoring, collecting, visualizing, and performance metrics of the deployed applications in production. These tools give greater visibility other than collecting the metrics also, where we can set up critical alerts, live views, and custom dashboards. CloudWatch Exporter is an open-source tool to capture metrics as defined in yml configuration file. Architecture The CloudWatch Exporter will collect the metrics from AWS Cloud watch every 15 seconds (default), and it will expose them as key/value pairs in /the metrics API response. Using that configuration, the exporter will collect those metrics from CloudWatch every 15 seconds (default) and expose them as key-value pairs in the '/metrics' API response. The CloudWatchExporter's /metrics endpoint should then be added to the Prometheus configuration as a scrape job. Prometheus allows us to define the scraping frequency, so we can adjust the frequency of calls to CloudWatch to eventually tune the cost.

What Are Events? API Calls

Aggregated on: 2023-05-01 19:30:25

It is always interesting to note how even today's Cloud giants continue to draw a largely imaginary line between Synchronous and Asynchronous HTTP Requests, such as in the case of a typical REST API call. This line, we are asked to believe, very clearly separates Synchronous Requests – where the Request is made and the caller holds the line until receiving a Response from the relevant HTTP API Endpoint – from Asynchronous Requests – where the caller fires off their Request, (typically) gets a 202 Status Code in reply, and then waits for the actual API Response via some other channel; such as a Webhook, WebSocket, or using the 'HTTP Polling' Pattern described by Microsoft in its Asynchronous Request-Reply pattern Article. We read in this same Article that: "Most APIs can respond quickly enough for responses to arrive back over the same connection… In some scenarios, however, the work done by [the] backend may be long-running, … [and] it isn't feasible to wait for the work to complete before responding to the Request. This situation is a potential problem for any synchronous request-reply pattern… Some architectures solve this problem using a message broker to separate the request and response stages… But this separation also brings additional complexity when the client requires success notification, as this step needs to become asynchronous."

How to Optimize CPU Performance Through Isolation and System Tuning

Unit testing is considered the first step of testing in the software development life cycle that involves validating each testable part (also known as units/modules/components) of a software application to determine each unit of the application's code works as intended. Unit testing is usually performed in the early development stages of an application by developers and QA engineers. The primary objective of unit testing is to isolate a code section and test its correctness. It helps uncover early bugs and flaws in application code that can be more challenging to identify in the later stages of the software testing life cycle (STLC).
