Logging in .NET
How .NET Core's ILogger abstraction, log levels, structured logging, and scopes work together, and how providers like Serilog plug in.
Monitoring and Event Logs
Learn how Windows Event Logs, Event Viewer, and key security event IDs help administrators detect AD problems and security incidents.
Logging and Observability with Serilog
Configure structured logging with Serilog and pair it with metrics and distributed tracing to build real observability into an ASP.NET Core API.
Handling Authentication in Tests
Learn how to bypass slow UI logins with programmatic authentication and cy.session() caching, and how to handle third-party SSO safely.
Monitoring and Logging
How Airflow's per-task logging works, how to configure remote logging for distributed deployments, and how to build alerting that avoids fatigue while catching…
Real-Time Data Logging
Techniques for capturing timestamped sensor data on Arduino to SD cards, EEPROM, or the cloud, using an RTC for accurate time and non-blocking timing for consi…
Events and Logging
Events emit indexed logs to the blockchain that off-chain applications can efficiently query, providing a cheap way to record activity that smart contracts the…
Error Logging and Robust Macros
Build VBA macros that fail gracefully by combining structured On Error handling, a central error handler, the Err object, and persistent logging to a file or w…
Logging in Nginx
How access logs and error logs work in Nginx, the difference between request_time and upstream_response_time for diagnosing latency, and how to control log vol…
Security Logging and Monitoring
Learn why insufficient logging and monitoring lets breaches go undetected for months, and how to build effective detection and response capability.
Logging in Spring Boot
How Spring Boot's default Logback-based logging works, including log levels, per-package configuration, and structured logging for production.
Logging in Node.js Apps
Learn why console.log is insufficient in production and how to implement structured logging with Winston or Pino.
Monitoring and Logging
Learn the difference between metrics, logs, and traces, and how alerting turns raw observability data into actionable operations.
Kubernetes Monitoring and Logging
Learn the core tools and patterns for observing cluster and application health: metrics, logs, and the Prometheus/Grafana stack.
Interview Questions(9)
What is Monitoring vs Observability?
Monitoring is watching a predefined set of metrics and alerts to detect known failure conditions, while observability is the broader capability to ask arbitrar…
What is Log Aggregation?
Log aggregation is the practice of collecting log output from many distributed services, containers, and hosts into one centralized system where it can be sear…
What is a Kubernetes DaemonSet?
A DaemonSet ensures that a copy of a specific Pod runs on every node (or a selected subset of nodes) in a cluster, automatically adding that Pod to new nodes a…
What is the Kubernetes Sidecar Pattern?
The sidecar pattern is a design where a helper container runs alongside a main application container in the same Pod, sharing its network namespace and volumes…
What is the ELK Stack and How Do Its Components Work Together?
The ELK Stack is a set of three open-source tools — Elasticsearch, Logstash, and Kibana — that together ingest, parse, index, and visualize log data, letting t…
What is OpenTelemetry?
OpenTelemetry is a vendor-neutral open-source standard — a set of APIs, SDKs, and a collector agent — for generating, collecting, and exporting metrics, logs,…
What Are Metrics, Logs, and Traces?
Metrics, logs, and traces are the three pillars of observability: metrics are aggregated numeric time-series data showing system health at a glance, logs are t…
What is Structured Logging and Why Does It Matter?
Structured logging means emitting log entries as machine-parseable key-value data, typically JSON, instead of free-form text sentences, so every field like req…
What is Log Rotation and Why is it Necessary?
Log rotation is the automated process of archiving, compressing, and eventually deleting old log files on a schedule or size threshold, so a continuously growi…
