Prerequisites
Before we begin, there are some prerequisites you’ll need to have in place:
Installing Netdata
There are 2 options to install Netdata on your Civo Kubernetes cluster:
- Civo Marketplace UI
- Civo CLI
Civo Marketplace UI
To install Netdata on Civo Marketplace, follow these steps:
Step 1: After you have launched your Kubernetes cluster, go to the "Kubernetes" section in your Civo dashboard and choose the specific Kubernetes cluster where you wish to deploy Netdata.
Step 2: In your chosen cluster's dashboard, locate the "Marketplace" section. Within the marketplace, navigate to the "Monitoring" category. From here, find and select the "Netdata" option. To start the installation process, click on "Install Apps."
Step 3: Upon successful initiation, you should see a confirmation message or progress indicator. Ensure that the installation is completed without any errors.
Civo CLI
To install Netdata through the Civo CLI, use the following command:
civo kubernetes applications add netdata --cluster Use the actual name of your Kubernetes cluster in place of CLUSTER-NAME. If there is no error during installation, the Netdata application will be successfully installed into the Kubernetes cluster, and you'll get this result:
The application was installed in the Kubernetes cluster Accessing the Netdata Dashboard
Netdata is made accessible in your Kubernetes cluster via a service using a mechanism called "NodePort." A NodePort service is a type of service that opens a specific port on all nodes and redirects traffic on that port to the service.
Once you've deployed Netdata in your Kubernetes cluster, you can easily access its Dashboard via these steps:
Step 1: Start by logging into your Civo dashboard and accessing you installed applications by going to "Kubernetes" > "Kubernetes Cluster" > "Installed Applications."
Step 2: Within the list of installed applications, locate and select the Netdata application.
Step 3: Upon selecting Netdata, you'll find usage instructions guiding you on how to access the dashboard. Follow the provided “Usage instruction” and access the Netdata Dashboard at http://localhost:19999.
Overview of Netdata
The Netdata Dashboard UI comprises various sections, each offering unique insights and functionalities for monitoring your Kubernetes cluster performance. Let's explore the different sections of the Netdata Dashboard UI in detail:
User Interface
The Netdata Dashboard UI offers a dynamic and intuitive overview of system performance in real-time. It has sections and dynamic charts that capture essential metrics such as CPU usage, memory utilization, disk I/O, network activity, and more.
These metrics provide immediate insights into the health and efficiency of your Civo Kubernetes cluster. You can also zoom, pan, and customize these charts, allowing you to focus on specific timeframes or metrics.
Kubernetes Map
Netdata's Kubernetes Map is a powerful visualization tool that offers a dynamic and intuitive representation of your Kubernetes clusters and their components. It provides a topological view of your Kubernetes infrastructure, illustrating relationships and connections between various entities like nodes, pods, services, and deployments.
The Kubernetes Map helps identify bottlenecks, performance issues, or potential failure points by providing a clear overview of how different components are interconnected. As you scale your Kubernetes deployment or make changes to your configurations, the map adjusts accordingly, giving you immediate insights into the impact of those changes.
Overall, the Kubernetes Map in Netdata offers a visually rich and dynamic representation of your Kubernetes infrastructure, promoting efficient monitoring, troubleshooting, and management of your Kubernetes environment.
Alerts
Alerts in Netdata are automated notifications triggered by defined thresholds or anomalies in system metrics. These notifications notify you of potential issues with your Kubernetes cluster.
To configure alerts in Netdata, you can define rules based on specific conditions related to metrics, including threshold values, patterns, or statistical anomalies. The configuration can be customized to send alerts via various channels such as email, Slack, webhooks, or even executing user-defined scripts. You have the flexibility to set the severity of alerts, control the notification frequency, and establish dependencies to avoid redundant alerts.
Plugins
Netdata offers a set of plugins designed to monitor specific applications or services running on your Kubernetes cluster. These plugins are tailored to collect and present performance metrics and insights related to the targeted applications. Each plugin is crafted to interface with the application it monitors, extracting valuable data on resource utilization, throughput, response times, and other relevant metrics. These insights are then presented in a visually informative manner within the Netdata Dashboard, enabling you to monitor the health and performance of your applications comprehensively.
Netdata’s plugins cover a broad spectrum of applications, allowing for extensive monitoring capabilities. It has databases like MySQL, and PostgreSQL, web servers like Apache and Nginx, and other specialized applications.
Events
The Events tab in Netdata is a vital feature that provides a clear and concise overview of important events and incidents that have occurred within your Kubernetes cluster. It serves as a timeline, presenting a chronological list of events such as system reboots, critical errors, alerts triggered, or any other noteworthy occurrences. Each event is accompanied by a timestamp and a brief description, enabling a quick understanding of when and what happened.
The Events tab includes the ability to add custom annotations. Operators can annotate events with comments or additional information, providing context or actions taken in response to the event.
