RED AND USE MONITORING APPROACHES
RED
• Rate: the number of requests our service is serving per second;
• Error: the number of failed requests per second;
• Duration: the amount of time it takes to process a request;
USE
• Utilization: the proportion of the resource that is used, so 100% utilization means no more work can be
accepted;
• Saturation: the degree to which the resource has extra work which it can’t service, often queued;
• Errors: the count of error events;
