Monitoring pod CPU usage percentage is a fundamental practice for Kubernetes clusters, but there are advanced techniques and tools that can enhance the monitoring capabilities. These techniques provide deeper insights and more granular control over the CPU usage metrics. Let's explore a few of these techniques:

Monitoring CPU Throttling

CPU throttling is a mechanism used to limit the CPU usage of containers or pods. It can be used to prevent a single container or pod from monopolizing CPU resources and impacting the performance of other workloads. Monitoring CPU throttling metrics can help identify if any containers or pods are being throttled and analyze the impact on CPU usage percentage. This information can guide resource allocation decisions and help optimize workload distribution across the cluster.

Prometheus provides metrics related to CPU throttling, such as the number of throttled periods, throttling time, and the reason for throttling. These metrics can be collected and visualized alongside pod CPU usage percentage metrics to gain a comprehensive understanding of CPU resource utilization.

By monitoring CPU throttling in conjunction with pod CPU usage percentage, administrators can proactively identify and address any resource contention issues to ensure optimal cluster performance.

Analyzing CPU Usage Patterns with Prometheus Query Language (PromQL)

Prometheus Query Language (PromQL) provides a powerful way to analyze and aggregate pod CPU usage percentage data. With PromQL, administrators can perform complex calculations, filtering, grouping, and data transformations to gain insights into CPU usage patterns.

For example, administrators can use PromQL to calculate the average CPU usage percentage across multiple pods, compare CPU usage trends over time, or identify outliers by finding pods with the highest or lowest CPU usage percentage.

By leveraging PromQL, administrators can derive meaningful metrics from the raw CPU usage data and gain a deeper understanding of the cluster's CPU resource utilization.

Customizing Dashboards and Alerts in Grafana

Grafana is a popular visualization and monitoring tool that works seamlessly with Prometheus. It provides a highly customizable dashboarding and alerting system, allowing administrators to create visualizations tailored to their specific monitoring needs.
