Summary of Changes
Hello @CaesarTY, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!
This pull request refactors the logging mechanism within the Multi-Cluster Services (MCS) controllers to adopt structured logging. The primary goal is to standardize log output into a machine-readable JSON format, which greatly improves the ability to collect, parse, and analyze logs using external systems, ultimately enhancing the overall observability and debuggability of the MCS components.
Highlights
- Structured Logging Adoption: I've migrated all
klog.Infof,klog.Errorf, andklog.Warningfcalls within the Multi-Cluster Services (MCS) controllers to their structured logging counterparts,klog.InfoSandklog.ErrorS. - Improved Observability: This change enables JSON-formatted logging, making it significantly easier for log aggregation and analysis tools to parse and process controller logs, enhancing overall system observability.
- Enhanced Debugging: By providing key-value pairs instead of formatted strings, logs now offer more contextually rich information, which should aid in quicker debugging and troubleshooting.

It's redundant to return an error and log it separately. The ErrorS function already logs the error, so returning it provides sufficient information. Returning fmt.Errorf("invalid key") doesn't provide any additional context since the error message is already present in the log.

it is not redundant, we need log the error for observability and return the error to handle it properly
