Data Collection for Containers

Data Collection for Containers

#410140

Densify can collect and analyze your container configuration and utilization data and then provide recommendations for optimizing your container-based applications.

Densify's container data collection consists of:

  • Deploying the Densify Data Forwarder container, in your current container environment, to collect deployment objects and utilization metrics from Prometheus and;
  • Configuring a connection between the Data Forwarder and Prometheus;
  • Forwarding the collected data to your Densify instance.

After the Data Forwarder sends the data to your Densify instance, it terminates. Your Densify instance then performs the optimization analysis on the collected data and generates optimization recommendations. The Data Forwarder is scheduled to run periodically during the day, sending the latest container metrics to your Densify instance for analysis.

Before you begin, refer to the prerequisites, listed below, for a list of container data collection requirements.

Densify's container data collection process consists of:

  1. Deploying the Densify Data Forwarder. This can be achieved through any one of the following methods:

  2. Once the Data Forwarder is able to send the collected container metrics to your Densify instance, your Cloud Advisor or support@Densify.com will enable the container optimization analysis and recommendations.

Prerequisites

The following items are necessary for Densify container data collection and optimization.

  1. Densify account— Contact Densify for details of your subscription or sign up for a free trial.
  2. Kubernetes or OpenShift must be deployed.
    • kubelet with cAdvisor is required to provide workload data to Densify
  3. kube-state-metrics—This service monitors the Kubernetes API server and generates metrics from the various objects inside the individual Kubernetes components. This service provides orchestration and cluster level metrics such as deployments, pod metrics, resource reservation, etc. The collected metrics allow Densify to get a complete picture of how your containers are setup. i.e. Replica Sets, Deployments, Pod and Container Labels.
  4. Prometheus—Provides the monitoring/data aggregation layer. It must be deployed and configured to collect kube-state-metrics and cAdvisor/kubelet metrics.

The following items are not mandatory but provide additional environment information for Densify's container optimization analysis.

  1. Node Exporter—Collects data about the nodes, on which the containers are running. This provides the classical host-related metrics such as CPU, mem, network, etc.
  2. openshift-state-metrics—These metrics provide additional details for OpenShift-specific items such as Cluster Resource Quotas (CRQ).

Contact your Cloud Advisor or support@Densify.com for configuration details.
