Kubernetes
Introduction
This O11ySource keeps a close eye on the performance, health, and overall state of your Kubernetes cluster. Since Kubernetes manages containerized applications and their dynamic orchestration, monitoring becomes crucial to ensure everything is running smoothly
Getting Started
Compatibility
The Kubernetes module is tested with the following versions of Kubernetes: 1.25.x, 1.26.x and 1.27.x.
Data Collection Method
vuSmartMaps uses Healthbeat agent to collect health and performance of the K8s Clusters.
Prerequisites
Inputs for Configuring Data Source
- Kubernetes Cluster Identifier: The IP Address/FQDN of the kubernetes cluster. This field is the key to identify each server you add here.
- Period (in seconds): How frequently data is gathered. period should be between 60 seconds - 3000 seconds
Firewall Requirement
To collect data from this O11ySource, ensure the following ports are opened:
| Source IP | Destination IP | Destination Port | Protocol | Direction |
|---|---|---|---|---|
| K8s Cluster Server IP | vuSmartMaps Data Collector Endpoint | 9092 | TCP | Inbound |
*Before providing the firewall requirements, please update the port based on the customer environment.
Configuring the Target
Kubernetes endpoints and metricsets of Healthbeat
Kubernetes is multi-layered by design. The telemetry has to be collected at different levels from various touchpoints and integration methods. Let us discuss all the touchpoints in this section.
In all these touchpoints, the /metrics api typically exposes the performance metrics.
Configuration Steps
- Enable Kubernetes O11ySource, if not already in Enabled state.
- Select the sources tab and press the button to add a new Kubernetes host that has to be monitored.
- After configuring the datasource, click the Save and Continue to download the agent.
- The following packages will be available for download:
- Kubernetes full installer package - Downloads the full Kubernetes based Healthbeat agent package with required configurations for a fresh installation
- Kubernetes config update package - Downloads the agent configuration package to update an existing Kubernetes based Healthbeat installation
- Download the agent installation or update package, then click Finish to close the data source window.
