About Foglight for Container Management

Containers are a method of operating system virtualization that allow you to run an application and its dependencies in resource-isolated processes. Foglight® for Container Management simplifies this process by tracking each container, the resources it consumes, and the remaining compute of the container host, as well as providing you with the cluster information and pre-configured rules with notifications identifying the problem of your clusters.

Architecture

Figure 1. Components of Foglight for Container Management

Foglight for Container Management consists of three main components:

•
Foglight Management Server and Foglight Database Repository — Responsible for managing, alerting, and viewing the collected data. Both components can be set to run on the same machine or reside on separate machines.
•
Agent Manager — Hosts the monitoring Kubernetes agents.
•
Docker Swarm clusters — Manages containerized applications in a clustered environment.
•
Kubernetes clusters — Manages containerized applications in a clustered environment.

Sizing Your Monitored Environment

Consider the possibility of a great amount of objects being collected, analyzed, and maintained by the application, several aspects of the underlying server must be taken into account. The sizing of the supporting clusters and containers depends on the complexity of the underlying environment. Sufficient processing power and CPU memory are required to support effective collection, server data handling, and analytics.
