PROFILE
Margaret Morehead
Margaret Morehead developed targeted monitoring and observability features for the vitessio/vitess and planetscale/vitess repositories over a two-month period. She introduced a per-cell tablet monitoring flag in VTOrc, enabling operators to selectively monitor and repair tablets based on user-defined criteria, which improved efficiency in large deployments. In addition, Margaret instrumented ZooKeeper connection metrics in zk2topo components, capturing lock acquisition times, retry counts, and state transitions to enhance end-to-end visibility and support SRE practices. Her work leveraged Go for backend development, focusing on robust monitoring, metrics, and testing, and demonstrated depth in both feature design and operational reliability.

Apr 1, 2026April 2026: Implemented cross-repo ZooKeeper connection metrics and observability in zk2topo components across planetscale/vitess and vitessio/vitess, delivering end-to-end visibility into ZooKeeper interactions. This work adds metrics for lock acquisition time, retry counts, and state transitions, enabling proactive alerting, SLA tracking, and performance optimization. The changes align telemetry with existing dashboards and SRE practices, strengthening reliability and incident response capabilities. While no customer-facing features were released this month, the observability improvements directly support data-driven capacity planning and faster MTTR.

Feb 1, 2026February 2026 — Delivered VTOrc Per-Cell Tablet Monitoring Flag to enable per-cell monitoring and selective repair in VTOrc. This flag allows operators to target tablets based on user-defined criteria, reducing monitoring overhead and accelerating issue isolation. Change implemented in vitessio/vitess with commit 560c56f14a07f19cb25f9caa3cb7cd2a0949fccc (Add flag for cells to watch to VTOrc (#19354)); Signed-off-by: Margaret Morehead.
