Lighttpd is an open source web server known for its flexibility and speed, providing a low memory footprint and small CPU load while remaining secure and compliant with web standards. Monitoring Lighttpd's performance can be challenging but features like its small CPU load make it easy to establish baselines, allowing users to ensure optimal performance. Datadog integrates with Lighttpd to help monitor key metrics such as CPU load, memory usage, and uptime, providing a visual representation of performance in a screenboard and enabling alerts for issues before they affect users. The integration also offers an out-of-the-box dashboard featuring useful metrics like number of requests, network traffic, and difference between hits/s and requests/s, helping to identify performance issues quickly. Additionally, the Datadog Agent collects various metrics from Lighttpd servers, including CPU usage, idle threads, uptime, bytes read and written, and request rates, allowing users to set up custom alerts for unexpected changes in these metrics. Overall, integrating Datadog with Lighttpd can help ensure optimal performance, security, and compliance of the web server.
