Complex information systems fail in unexpected ways. Observability gives developers and system operators real-time awareness of a highly distributed system’s current state based on the data it generates. With observability, teams can understand what part of a system is performing poorly and how to correct the problem.

It was 2005, and I felt like I was in the eye of a hurricane. I was an independent performance consultant and Sun Microsystems had just released DTrace, a tool that could instrument all software. This gave performance analysts like myself X-ray vision. You can't make this stuff up. I was living in Sydney, Australia.

The problem is that this system has a default libc that has been compiled without frame pointers, so any stack walking stops at the libc layer, producing a partial stack that's missing the application frames. I'm sure this delivered large performance improvements and I wouldn't try arguing against it.

To me, the analogy breaks down before it begins: firstly, LLMs don’t merely blur, but perform highly non-linear transformations, which means you can’t just squint and get a sense of the original; secondly, for the photocopier, the error is a bug, whereas, for LLMs, all errors are features. joined Flickr.

The system table sys.sysprocesses was replaced way back in SQL Server 2005 by a set of dynamic management views (DMVs), most notably sys.dm_exec_requests , sys.dm_exec_sessions , and sys.dm_exec_connections. We recommend that you use the current SQL Server system views instead. Why this is a problem. dm_os_performance_counters.

Going back to the mid-1990s, online systems have seen relentless, explosive growth in usage, driven by ecommerce, mobile applications, and more recently, IoT. For more than two decades, the answer to this challenge has proven to be a technology called in-memory computing. From Distributed Caches to Real-Time Digital Twins.
