Recently, Rancher Labs announced that it will strengthen its support for Prometheus and improve the visibility of Kubernetes clusters. As a result, Rancher is the only solution that supports Prometheus in a multi-cluster, multi-tenant environment.

Prometheus is rapidly becoming one of the most popular and essential tools for monitoring cloud native applications. Rancher's unique multi-cluster and multi-tenant management features enable users to deploy Prometheus on all Kubernetes clusters more safely and efficiently.

Liang Sheng, co-founder and CEO of Rancher Labs

Rancher is the first and only enterprise-class Kubernetes management platform in the industry that can manage all clouds, all distributions, and all Kubernetes clusters. The enhanced integration with Prometheus will provide higher visibility across multiple Kubernetes clusters and multiple isolated tenant environments. The enhanced support for Prometheus released this time is as follows:

Whenever a new Kubernetes cluster is added to the Rancher, Rancher will deploy a Prometheus operator in the cluster and then create a Prometheus deployment in the cluster.

Cluster-wide Prometheus deployments will be used to store cluster metrics (such as CPU nodes and memory consumption) and to store project-level metrics collected from applications deployed by a single user.

Communication between the project-level Grafana and the Prometheus will be done through a security agent that implements multi-tenancy for the Prometheus. The security agent tool PromQL statement ensures that queries can only be made through the namespace of the user's project.

This time Rancher's enhanced support for Prometheus will ensure efficient deployment and effective monitoring for all Kubernetes clusters, all projects, and all users. The security agent ensures that data is not shared repeatedly among multi-tenants and that multi-tenancy is isolated. In addition, Rancher collects any custom metrics for exposing endpoints using data processed by Prometheus. All metrics can be used for alarms and decisions within Rancher. Simple operations are carried out by notifying users of Slack and PagerDuty, and complex operations are carried out by starting the horizontal expansion of the workload and finally increasing the load. Rancher also now has full security isolation and RBAC cluster-level and project-level metrics and dashboards.

We use Rancher as a single pane of glass to run mission-critical applications with enterprise control and visibility in multiple clusters, and it is important to check the health of these applications, and we look forward to Rancher's enhanced support for Prometheus, which allows us to further see more metrics of our Kubernetes cluster.

-Greg Cordell, director of Cardlytics IT and SRE

Since its inception, Rancher has been committed to building an open container ecosystem with the core of helping container technology to be implemented on the ground, and has maintained close cooperation with major public cloud, operating system, storage, security and other vendors, including Docker, AWS, Google, Microsoft, Huawei, Aliyun, Tencent Cloud, Ubuntu and other industry giants.

A trial version of beta with enhanced support for Prometheus will be available soon, and GA will be available in early 2019.
