bookVisualizing Monitoring Data

When you monitor systems and applications as a DevOps engineer, you collect a lot of dataβ€”such as CPU usage, memory consumption, disk activity, and network traffic. While raw numbers and logs are valuable, they can be overwhelming and difficult to interpret at a glance. This is where data visualization becomes essential. By transforming numeric data into visual graphs and charts, you can quickly spot trends, anomalies, and patterns that may indicate issues or opportunities for optimization. Visualization makes it easier to communicate findings to your team and enables faster, more informed decision-making.

import matplotlib.pyplot as plt # Hardcoded CPU usage values over time (in percent) cpu_usage = [20, 35, 30, 50, 45, 60, 55, 70, 65, 80] time_points = list(range(1, len(cpu_usage) + 1)) plt.plot(time_points, cpu_usage) plt.show()

The code above demonstrates a simple way to plot monitoring data using matplotlib. In this example, you have a list of CPU usage percentages recorded at different time points. The plt.plot() function draws a line graph, with each point representing CPU usage at a specific time. The x-axis shows the time points, while the y-axis shows CPU usage percentage. Interpreting this graph allows you to see how CPU usage changes over time, helping you identify spikes, trends, or periods of high resource consumption that may need further investigation.

To make your plots more useful and easier to understand, you can add labels, titles, and other customizations.
