Csysdig explained visually
Blog post from Sysdig
Csysdig is an open-source, interactive troubleshooting tool for Linux, designed for monitoring and debugging containers by capturing system call data, similar to an htop tool but specific to container environments. It supports various container platforms such as Docker, Rkt, and LXC, and can map container activities to Kubernetes and Mesos concepts, offering a comprehensive view of CPU, memory, network, and file I/O usage. Users can utilize Csysdig for live monitoring and historical analysis through "captures," allowing troubleshooting of containers both on and off-host. The tool provides various views and filtering options, powered by Lua-based plug-ins called Chisels, enabling users to customize how data is aggregated and displayed. Additionally, Csysdig allows users to perform actions on containers such as stopping, killing, inspecting logs, and launching shells, while also offering unique visualization features like spectrograms for analyzing time-based data. The tool serves as an educational resource for learning sysdig's filtering language and can be integrated with Sysdig Monitor for enhanced monitoring capabilities across multiple hosts.
