Apr 1, 2025Month: 2025-04 | mozilla/metric-hub performance highlights: focus on iOS Firefox tab sharing metrics instrumentation and disciplined change control to ensure data quality. Key achievements: - Implemented iOS tab sharing metrics tracking: added configuration and metrics for total tab shares, shares to WhatsApp, and any WhatsApp share, plus custom metrics from the iOS event stream. (Commits: c294038f1cf59a23a822143efa1c1b7714ab1ee9; 122c86736f416ab0a7aa075a1f14fcf23786ecf9) - Created and integrated a TOML-based configuration for the metrics pipeline to support the iOS sharing telemetry. (Commit: "add toml file" (#831)) - Maintained data integrity through a rollback: reverted ios-sent-from-firefox.toml configuration to avoid misreported WhatsApp sharing metrics. (Commit: a478c3f654ba3117972a5e50f7fdb00179296df3) - Demonstrated disciplined instrumentation and version-control hygiene, ensuring changes are observable, reviewable, and reversible if needed. Impact and value: - Provides actionable visibility into iOS tab sharing behavior and WhatsApp engagement, enabling data-driven product decisions and UX improvements for Firefox on iOS. - Keeps telemetry accurate and stable by promptly reverting configuration changes that could skew metrics, reducing data quality risk.
