During five months on the mozilla/looker-spoke-default repository, Ben Wu developed and enhanced data monitoring and analytics features using LookML and SQL. He built Looker explores and dashboards to track shredder job statistics, table partition expirations, and BigQuery usage, enabling granular visibility into data processing and resource consumption. His work included adding rolling metrics for schema errors, ping activity, and weekly data volumes, as well as improving health check dashboards and bug reporting templates. By refining data modeling, implementing robust type handling, and simplifying configuration, Ben improved observability, reliability, and capacity planning for business intelligence and data engineering workflows.

Jun 1, 2025June 2025 monthly summary for mozilla/looker-spoke-default: Delivered a key feature that enhances monitoring by adding a total_ping_count metric to the structured_missing_columns and schema_error_counts views. The 7-day rolling total uses the latest joined table to provide combined visibility of ping activity with schema errors and missing columns, improving observability and alerting. No major bugs fixed this month; one important commit corresponds to DENG-7602. Overall impact centers on improved data quality, faster triage, and stronger reliability for data pipelines and dashboards.

Nov 1, 2024Month: 2024-11 Overview: Delivered new Looker explorations for shredder job statistics and table partition expirations in the mozilla/looker-spoke-default repo, improving observability and operational efficiency for data processing tasks. A focused effort on telemetry and analytics metrics provides stakeholders with visibility into runtimes, resource usage, and task categorization. While no major bug fixes were recorded this month, the feature work lays a strong foundation for proactive reliability and optimization. What was delivered: - Looker Explores: Added Looker explores to monitor shredder job runtimes, slot usage, and job type categorization, supporting end-to-end visibility of data processing and expiration tasks. This enables faster diagnostics and data-driven capacity planning. - Telemetry and metrics: Implemented metrics around runtimes, resource utilization, and categorization to drive performance improvements and SLA alignment. - Traceability: Committed changes documented for future audits and rollbacks; relates to the commit 40ab7256e1ab692bdbc0703efe502e689ced1e5f with message: 'Add shredder and expiration monitoring explores'. Business value and impact: - Operational visibility: Immediate access to key performance indicators for shredder jobs and expiration tasks reduces MTTR and supports proactive incident response. - Resource optimization: Data-driven insights on slot usage and runtimes enable better capacity planning and potential cost savings in processing tasks. - Strategic readiness: Establishes a foundation for further analytics improvements (retention policy validations, partition-level optimizations, and alerting). Technologies/skills demonstrated: - Looker: Explore design, metrics, and dashboards for data-processing workflows. - Telemetry and observability: Instrumentation to capture runtimes, resource usage, and task categorization. - Git and release management: Traceable commits and clear documentation of the feature work.
