Metrics Collection and Monitoring at Robinhood Engineering
The Robinhood server operations team published a series of articles talking about their metrics collection, monitoring and alerting infrastructure. OpenTSDB, Grafana, Kafka and Riemann form the core of the stack, with Kafka acting as a proxy layer from which the data is pushed into Riemann for stream processing of the metrics and into OpenTSDB for storage.

Leveraging Data Science to Improve Monitoring
At the recent devopsdays Amsterdam 2015, Patrick Roelke contended that monitoring still has lots of issues. Roelke believes that data science can help by eliminating static thresholds and coalescing information from various data sources into a single metric. The talk included a quick overview of monitoring tools that leverage data science: Kale, Bosun and AnomalyDetection.
