Sematext Agent

Sematext Agent collects a plethora of metrics about hosts (CPU, memory, disk, network, processes), containers (both Docker and rkt) and orchestrator platforms and ships that to Sematext Cloud⁠. To gain deep insight into the Linux kernel, Sematext Agent relies on eBPF to implant instrumentation points (attach eBPF programs to kprobes) on kernel functions. This allows for a very efficient and powerful system exploration approach. It has auto-discovery capabilities of services deployed on physical/virtual hosts and containers, as well as a mechanism for reporting inventory info. It also collects events from different sources such as OOM notifications, container or Kuberentes events.

Capabilities

• Provides full visibility over the basic operating system metrics on your hosts. For example, you can easily spot CPU spikes and correlate them with other metric sources.
• Agnostic and unified container monitoring to gain deep visibility into your containerized deployments and orchestration platforms.
• Discovers your network topology⁠ with the eBPF-driven ultra efficient observability tracers.
• Collects a myriad of events such as Docker/Kubernetes life cycle events, package install/uninstall, OOMK or signal notifications among others.
• Inventory tracking⁠ of your whole infrastructure including packages, server details, container metadata and more.
• Process monitoring⁠ that helps out identifying top CPU or memory consumers.
• Service discovery and automated monitoring for vanilla Docker and Kubernetes workloads.

Preparation

To run Sematext Docker Agent you will need a Monitoring App Token and a Logs App Token. If you don't have Monitoring and/or Logs Apps yet, you can create a Docker Monitoring and Logs Apps now⁠.
