A system is experiencing high latency. You need to identify if the latency is caused by external dependencies. Which of the Four Golden Signals is most relevant for this discovery?
A team is transitioning from a traditional logging system to a metrics-based monitoring approach. Which category of observability data should the team prioritize to specifically identify the 'Latency' golden signal?
You are designing a monitoring architecture for an ephemeral, auto-scaling microservices environment. Why is the Prometheus 'pull' model generally preferred over a 'push' model in this scenario?
You are monitoring a legacy batch processing job that runs for only 30 seconds once every 24 hours. Which Prometheus component is necessary to collect these metrics?
An application is emitting logs that contain '5xx' status codes when a service is unavailable. If you want to create an alert that triggers based on the rate of these errors, what is the best practice for observability?
A developer asks why they should use Distributed Traces instead of simply using high-cardinality metrics to debug a slow request. What is the primary advantage of traces?
An engineer observes a massive spike in Prometheus memory usage after introducing a new custom label that includes a unique user ID. Which observability concept is being violated?
