nginx 502 or 504 on a Node.js or Laravel app: find the failing boundary
A gateway error is a symptom. Separate a dead upstream, a slow handler, an exhausted worker pool and a timeout mismatch before increasing limits.
Engineering write-ups on it support from deployments KYCONNECTS has run, with the reasoning behind each approach.

A model endpoint can be healthy while the business workflow produces unusable work. Trace jobs across retrieval, generation, validation and review while keeping sensitive content out of routine telemetry.
A threshold can tell you a server is busy without telling you whether anyone should respond. Build service objectives and error-budget alerts around the customer journeys the business depends on.
A slow laptop, unstable access path or failing business application can look like a productivity problem. Measure the technology experience of remote work without turning diagnostics into employee surveillance.
Activity data can describe a device session without explaining the value of the work. Build a balanced measurement model around outcomes, quality, workload and the conditions employees face.
An agent on every desktop, a server that must never lose a capture, and many companies' data on one platform that must never mix. The architecture that follows from those three constraints, and why each piece is the shape it is.
Monitoring software is bought to answer a management question and usually creates a trust problem instead. The deployments that work are narrow, disclosed, and answer a question the business had actually written down first.
The order matters more than the list. Most IT programmes fail not because the wrong things were chosen but because they were attempted in an order where each depended on something that had not been done yet.
What a business of thirty to three hundred people actually needs, layer by layer, with the decision each layer turns on. Not a shopping list — a map of which choices are consequential and which are not.
Education IT is shaped by three things no ordinary business faces: everyone arrives at once, the user population turns over almost entirely each year, and a large part of it is actively curious about the network.
Zabbix and Prometheus are both described as monitoring and are built for different jobs. Zabbix is an integrated system that arrives knowing what a server, a switch and a printer are. That difference is what should decide which one a growing business runs.
Logs answer the questions metrics cannot, and they are the first thing an attacker deletes. Loki makes keeping them affordable by indexing labels rather than log text — which is exactly why the labels have to be chosen carefully.
