November 2015 Summaries

Sysdig has announced the integration of its Docker monitoring tools with Rancher, enhancing its capabilities in containerized and microservices infrastructures. Sysdig, known for its open-source system visibility tool and Sysdig Cloud, a comprehensive container monitoring solution, now allows users to deploy these tools directly via the Rancher Catalog. This integration simplifies the deployment process by enabling one-click installations and providing deep, container-native visibility and monitoring across infrastructures. The technology behind Sysdig, including the patent-pending ContainerVision, allows automatic detection and monitoring of containers without additional configuration. This partnership leverages Rancher’s orchestration capabilities to streamline container management and monitoring, offering users an efficient way to manage their containerized environments.

Sysdig Cloud offers a sophisticated solution for monitoring Docker containers, providing insights and alert capabilities that are crucial for DevOps projects. The platform allows users to easily deploy the Sysdig Cloud container within minutes and begin monitoring individual Docker containers or clusters without requiring extensive configuration. Users can explore various metrics such as CPU and memory usage, and set up alerts for conditions like a decrease in the number of running containers or if a container goes down. This capability is particularly beneficial for monitoring infrastructure in environments like e-commerce web applications. The author, Ranvijay Jamwal, a DevOps Engineer at TO THE NEW Digital, highlights the seamless integration and ease of use of Sysdig, which enables users to gain valuable insights into their Docker environments and set up alerts in just a few clicks.

Sysdig's experience at DockerCon Europe in Barcelona was marked by engaging interactions with attendees passionate about Docker and container technologies, emphasizing the importance of container-native monitoring and visibility. As a first-time participant, Sysdig highlighted its mission to facilitate the use of production containers and microservices by addressing the visibility challenges associated with new platform technologies. The event was an opportunity for Sysdig to connect with both seasoned professionals and newcomers exploring the benefits and challenges of containers, while also inviting attendees to try out Sysdig Cloud with a special discount.

Kubernetes, a leading technology in IT, enhances scalability and service-based application development by managing container operations like grouping, discovery, load balancing, and healing, though often at the expense of system visibility. Sysdig addresses this challenge by integrating native Kubernetes support into its tools, Sysdig Cloud and the open-source system exploration tool, sysdig. This integration allows users to access detailed insights into their Kubernetes infrastructure, such as namespaces, services, replication controllers, and labels, thereby simplifying exploration and troubleshooting. With the addition of Kubernetes awareness, sysdig provides enriched views and control functionalities in its ncurses UI, csysdig, enabling users to navigate through their Kubernetes environment more effectively. It also introduces advanced filtering capabilities in the classic sysdig interface, allowing for precise and complex data querying. These enhancements position sysdig as a powerful tool for both novice and expert Kubernetes users, offering comprehensive visibility of distributed infrastructures through dashboards, charts, topology views, and alerting in Sysdig Cloud.

Csysdig, an ncurses user interface for sysdig, has introduced a new feature that allows users to perform actions directly from the interface, enhancing its functionality beyond merely exploring information. Previously focused on observation, the update now enables users to execute actions such as killing processes, attaching to containers, and other custom commands through simple keyboard mappings. This integration provides a seamless workflow for users navigating processes, network connections, and Docker containers, allowing actions like generating core dumps, running tcpdump captures, and managing container operations with ease. The interface is customizable with Lua scripts, enabling users to create personalized hotkeys, while the default set of commands is designed to be practical and time-saving, particularly for Docker-related tasks.

Monitoring file systems and file I/O in containerized environments like Docker is challenging due to the isolated nature of containers, which obscures access to essential metrics such as file system activity. Sysdig Cloud addresses this issue by offering comprehensive visibility into container-level file system metrics, which are typically difficult to obtain. Unlike traditional tools that report basic metrics like CPU, memory, and network usage, Sysdig Cloud provides in-depth insights into file system size, usage percentages, type, and mount directories, along with detailed file I/O metrics including file activity, IOPS, and errors. This enhanced visibility not only facilitates real-time monitoring and alert creation for issues like disk space consumption but also simplifies deep troubleshooting by retaining historical data, eliminating the need for cumbersome access to individual containers. Sysdig Cloud's capabilities are poised to significantly enhance the management and security of containerized environments.

Sysdig has announced the launch of its new Cloud API, which aims to enhance Sysdig Cloud's functionality by allowing users to programmatically manage alerts through a comprehensive framework that includes authentication and detailed documentation. The current API capabilities enable users to create, edit, delete, enable, and disable alerts, facilitating tasks such as automatically disabling alerts during disruptive activities like code deployments and integrating alert creation into deployment cycles. Sysdig is seeking beta users to test advanced features and encourages feedback and participation to further expand the API's potential, highlighting that this release is just the beginning of future developments.
