We have chosen cAdvisor as it comes with native support for Docker containers and is ready to use with additional container environments, like Kubernetes. cAdvisor is a daemon that collects container monitoring data in real-time. cAdvisorĬAdvisor, which stands for Container Advisor, is an open-source tool developed and maintained by Google. The Docker Cloud Exporter is a Prometheus-compatible endpoint that exposes the health of stacks, services, nodes, and node clusters via the Docker Cloud API. The exporter can retrieve statistics from DockerHub for particular images, organizations, or people. The Docker Hub Exporter for Prometheus exposes metrics from the Docker Hub API, such as container pulls and stars, to a Prometheus-compliant endpoint. The Alertmanager then takes over the management of those alerts, including silencing, inhibition, aggregation, and communication via email, on-call notification systems, and chat platforms. Alerts are sent to an Alertmanager by Prometheus servers’ alerting rules. There are two stages to alerting using Prometheus. This is useful in situations where directly instrumenting a system with Prometheus metrics is not possible. We have chosen Prometheus as its monitoring system comes with a comprehensive, multidimensional data model as well as PromQL, a short and powerful query language.Įxisting metrics from third-party systems can be exported as Prometheus metrics using a variety of libraries and servers. SoundCloud developers created Prometheus, an open-source monitoring system, in 2012.
