I’ve recently been building some hobby code to dogfood the various observability tooling we develop at Elastic. Additionally, I’ve been interested in identifying the pain points of using our products as well as the .NET instrumentation libraries (from System.Diagnostics) used to instrument code in an OpenTelemetry-compatible way. Recording Activities in .NET In today’s short post, […]
Understanding System.Diagnostics DiagnosticSource and DiagnosticListener (Part 1)
Throughout its history, .NET has evolved various mechanisms to “log” diagnostic information inside applications and libraries, including TraceSource, EventSource, ILogger, and DiagnosticSource, the subject of this post. TraceSource is a legacy option and is rarely used in new code. ILogger is a simple structured logging abstraction that is well suited to many applications, although it […]
Authenticating a .NET GitHub App using a JSON Web Token (JWT)
SERIES: A Guide to Developing GitHub Apps on .NET In this post, I cover the steps required to create and sign a JSON Web Token, herein abbreviated as JWT, to authenticate a GitHub App built using .NET. I want to state clearly up front that I’m learning as I go while experimenting with a hobby […]
Profiling Memory Allocations on Linux using the JetBrains dotMemory Command-Line Profiler
In a previous post (Automating memory profiling with the JetBrains dotMemory Profiler API), I described the steps that could be used to automate the collection of memory snapshots and profiling data by using the JetBrains Profiler API NuGet package. In that post, we triggered the profiling session using the dotMemory application on Windows. As part […]
Automating Memory Profiling with the JetBrains dotMemory Profiler API
Those who have read some of my previous performance-focused blog posts will know that I use the dotMemory product from JetBrains when working on code optimisations. In this post, I want to demonstrate a really handy, but somewhat underutilised feature, to automate the collection of snapshots in a repeatable way. I use these steps quite […]
