Before you start testing and validating your cloud logging and monitoring configurations and policies, you need to have a clear idea of what you want to achieve and how you will measure it. What are the key performance indicators (KPIs), service level objectives (SLOs), and service level agreements (SLAs) that you need to track and report on? What are the thresholds and alerts that you need to set up and respond to? What are the compliance and security standards that you need to follow and enforce? By defining your objectives and metrics, you can align your cloud logging and monitoring strategy with your business goals and expectations.
A good place to begin when defining your objectives is to take all the user journeys that you want to monitor and for each one of them define separate Service Level Objectives (SLOs). Google offers resources on the topic, search for "the Art of SLO". You should define your SLOs in a way that they can capture disruptions in the user experience. For example, if we see a high error rate on one endpoint, and this endpoint is part of a user journey then that part of the user journey is disrupted. A good basis to start when trying to define metrics is the "4 golden signals" from the Google SRE book: Latency, Traffic, Errors, and Saturation
Testing cloud logging and monitoring configurations is crucial for system reliability. Simulate events, set thresholds for metrics, and manually inspect log entries. Test integration with applications and infrastructure, verify alert configurations, and ensure proper logging retention and archiving. Conduct security testing, assess performance impact, and simulate failure scenarios. Test across multi-regions or clouds and use automated testing scripts. Regularly review documentation to keep your team informed and prepared. This systematic testing helps identify issues and ensures a reliable monitoring setup for timely incident response
