Sematext Container Monitoring
Brooklyn, New York, USA
What it is
Sematext Container Monitoring provides visibility into distributed infrastructure through host and container metrics, logs, and events. Its Sematext Agent runs in a lightweight container and can be deployed as a Kubernetes DaemonSet, Docker Swarm service, with Rancher, Nomad, Portainer, Mesos, or DC/OS, or with a docker run command. Automatic discovery can find applications in containers and start monitoring agents. Dashboards and alert rules are provided out of the box, while a shared dashboard lets you filter metrics, logs, and events together. Troubleshooting views show hot containers, top processes, replica counts, and pod restarts. The service supports Docker Engine, Docker Data Center, Docker Enterprise, Kubernetes, managed Kubernetes platforms, Nomad, Docker Swarm, Mesos, and Rancher. It lists more than 100 integrations, including six in its servers, containers, and orchestration category. A 14-day trial requires no credit card. The Basic Infra Monitoring plan starts at $2.80 a month, with metered charges based on hosts, containers, plan, and retention.
