Sematext Container Monitoring
Sematext Container Monitoring provides visibility into containerized and distributed infrastructure. Its lightweight Sematext Agent runs as a container and gathers host and container metrics, logs, and events. Deployment options include Kubernetes DaemonSet, Docker Swarm, Rancher, Nomad, Portainer, Mesos, DC/OS, or a docker run command. The service can discover applications in containers and start monitoring agents automatically. Dashboards and alert rules are supplied for collected data, while a shared dashboard lets you filter metrics, logs, and events together. Troubleshooting views show hot containers, top processes, and Kubernetes details such as replica counts and pod restarts. Supported environments include Docker platforms, Kubernetes services, AWS ECS and EKS, AKS, GKE, OpenShift, and others. The product lists more than 100 integrations. A free plan and 14-day trial are available; the trial requires no credit card. Basic Infra Monitoring starts at $2.80 a month, with metered usage.
