 The huge scale of services and the diverse monitoring requirements bring great challenges to timeseries database’s reliability, availability, and performance. With year’s evolution, we finally build a metrics system around VictoriaMetrics, aiming to solve following problems:
-* Weak observability on application layer: in the past, internal monitoring of the product mainly focused on machine level. Although it also provided monitoring plugins for common frameworks, there was still room for improvement in both performance and visualization effects.

-* Linking metrics to trace: metrics are the most intuitive way to discover problems, such as "getting 10 failed http requests in the past 30s", but sometimes traces are also needed to locate the root cause of the errors.

 Alerts are evaluated on vmalert when necessary, either because metrics from multiple sources are needed or because the source is Prometheus in agent mode (mostly for kubernetes clusters). Prometheus Alertmanager and Grafana+Promxy combine all sources together so that the end users of dashboards (and ideally the recipients of alert notifications) don't have to worry where to look for some information.

 To address these challenges, we decided to migrate to VictoriaMetrics. We were drawn to its reputation for high performance, low resource usage, and scalability. The migration process was carefully planned to ensure a smooth transition with minimal disruption. We focused on:
-  - **Data Optimization**: We reduced unnecessary metrics to minimize data ingestion and storage needs.

-  - **Performance Enhancements**: VictoriaMetrics’ efficient query processing allowed us to achieve significantly faster query response times.

 ### The Results
 
 Post-migration, we successfully scaled our monitoring infrastructure to handle billions of data points daily, all while experiencing faster query performance and 60% reduction in yearly infra cost. The improved observability has enhanced our ability to deliver reliable service, allowing us to troubleshoot issues more quickly and effectively.
