The Eye
1 like1,006 views
The document discusses the shortcomings of traditional monitoring and advocates for a test-driven monitoring approach called TheEye. It notes that traditional monitoring provides too much redundant information and that the key things to monitor are whether tests pass, response times are low enough, and the system is functioning properly. TheEye runs tests on a project or system at regular intervals to check functionality and collects the results to monitor health. Collectd is recommended for collecting additional system metrics when needed.
