Mackerel is a cloud-based SaaS service for monitoring servers and team-managed infrastructure. Installing its agent starts monitoring, after which hosts can be grouped into services and roles. It visualizes host metrics and user-defined service measures, including response time, sales and page views. Monitoring features include combining metrics, tracking predicted values and machine-learning anomaly detection. Cloud integrations cover Amazon Web Services, Microsoft Azure and Google Cloud; a container agent treats Amazon ECS tasks and Kubernetes pods as hosts. Users can extend monitoring with open-source plugins, APIs and the mkr command-line tool. Customer Reliability Engineers can offer technical guidance on implementation and use, while standard-plan technical support is email-only. The free plan has five standard and micro hosts total, 500 metrics, one-day retention, 10 monitoring rules, one dashboard and up to 5M trace spans. A two-week trial includes Standard-plan functions and a 100M-span allowance. Standard host usage costs 2,180 yen, tax included, per host month.
