The blog post by Levent Ogut delves into the importance of monitoring web servers for optimal customer engagement in web applications, using Apache as a case study. It highlights the use of Logz.io for monitoring, which involves the integration of the ELK Stack for logging, Prometheus for metrics and alerts, and Jaeger for distributed tracing. The post provides a detailed walkthrough for setting up Apache on Ubuntu 20.04 LTS, configuring Filebeat to ship logs to Logz.io, and using Prometheus with Apache and Node Exporters to collect metrics. It emphasizes the visualization of metrics through Logz.io's Metrics UI and ELK Apps, which offer pre-built dashboards for Apache metrics. The post also discusses Logz.io's "Exceptions" feature, which uses machine learning to analyze logs for anomalies, aiding in troubleshooting and system observability. It concludes by suggesting the potential of application-level monitoring and tracing for deeper insights, inviting readers to explore these capabilities further.
