What is the key difference between monitoring and observability?

Monitoring is only for infrastructure, while observability is only for applications

Monitoring uses predefined metrics and alerts, while observability enables exploring unknown issues by querying telemetry data

Monitoring uses logs, while observability uses metrics

Monitoring is reactive, while observability is proactive

A team runs a Kubernetes cluster and wants to centralize logs from all pods. They plan to use a log aggregation system. Which of the following is a common and effective way to collect logs from pods in Kubernetes?

Use kubectl logs to stream logs from all pods to a file.

Configure each pod to send logs directly to a central database using a sidecar container.

Enable Kubernetes audit logging and send those logs to the aggregation system.

Deploy a DaemonSet that runs a log-collection agent on each node to collect container logs.

A developer wants to add structured logging to a microservice so that logs can be easily queried by fields like 'user_id' and 'order_id'. What is the best practice for log format?

Use plain text with a consistent delimiter like '|'.

Use JSON format with key-value pairs for each field.

Use a single-line string with all information concatenated.
