APM Tips
About APM Tips
APM Tips is an independent publication about application performance monitoring: how to instrument an application, query what it records, alert on what matters and keep the bill under control.
What we publish
- Guides that answer one practical question each, starting with the answer. The first hub covers Azure Monitor Application Insights, for both the classic SDK and the OpenTelemetry-based distros that replace it.
- A KQL library of queries for the Application Insights tables, each explained: what it returns, which table it reads and the mistakes that skew its numbers.
- Tools: a sampling and ingestion cost calculator and a KQL query builder.
- A glossary of the vocabulary, one term per page.
OpenTelemetry references and a comparison of APM products are planned next, in that order.
Who writes it
APM Tips launched in 2026 and is written by the APM Tips editorial team, for engineers who run monitoring for production systems. Every guide is checked against the vendor and OpenTelemetry documentation it relies on, and lists those sources with the day they were last checked. The editorial policy explains how topics are chosen, how facts are checked and how corrections work.
