Metric Dashboards
Collect metrics from your code and chart them on interactive dashboards; dozens of auto-generated dashboards, build custom dashboards in minutes, export and share charts, fullscreen view, and compare timeframes.
Log Management
Centralized log management, simple search and filtering, links to error and performance issues, and log custom attributes.
