Container monitoring is a process of collecting and analyzing performance data from containerized applications to detect and troubleshoot problems. It shares similarities with traditional application performance monitoring (APM) in that it collects metrics, logs, and traces, but it differs due to the unique nature of containers, which generate different types of observability data and have ephemeral characteristics. Effective container monitoring requires correlating data from across all layers of the hosting stack, monitoring continuously in real-time, managing data efficiently, keeping tools lightweight, and being agnostic to various container environments. The best practices for container monitoring include using a platform-agnostic tool like groundcover, which enables fast, accurate insights into cloud-native environments, and adopting intelligent alerting capabilities, distributed tracing, and support for monitoring the entire stack.

The traditional approach to monitoring and observability involves deploying software agents on each server being monitored, which increases CPU and memory utilization. This can lead to performance issues as the servers become overloaded. In contrast, eBPF (extended Berkeley Packet Filter) is a novel and efficient approach that allows for monitoring and observability with minimal system load. eBPF enables better visibility into system operations, reduces CPU and memory overhead, and integrates directly into the kernel. It can be used to deploy custom programs in kernel space, making it an ideal solution for monitoring and observability. Groundcover is a tool that uses eBPF as its primary means of data collection, providing efficient observability with minimal resource overhead. By switching to eBPF-based observability, organizations can avoid the costs associated with traditional approaches and get a free ride in terms of system load.
