Sematext Container Monitoring
What Sematext Container Monitoring is
Sematext Container Monitoring provides visibility into the health and performance of distributed infrastructure. Its lightweight Sematext Agent collects host and container metrics, logs, and events. The agent can run as a Kubernetes DaemonSet, Docker Swarm service, with Rancher, Nomad, Portainer, Mesos, or DC/OS, or through a docker run command. Sematext can discover applications running in containers and start monitoring agents when it finds them. Dashboards and alert rules are available out of the box, and metrics, logs, and events can be viewed and filtered together. Real-time troubleshooting views cover hot containers, top processes, and Kubernetes details such as replica counts and pod restarts. The product lists support for Docker Engine, Docker Data Center, Docker Enterprise, Kubernetes, AWS ECS, AWS EKS, AKS, GKE, Red Hat OpenShift, Nomad, Docker Swarm, Mesos, and Rancher. It lists 100+ integrations overall. A 14-day free trial is available without a credit card. Infra Monitoring Basic starts at $2.80 a month; charges depend on hosts, containers, plan, and data retention.
