Go applications can be effectively monitored using the Elastic Stack, specifically leveraging Metricbeat, a lightweight data shipper designed to track service and server metrics. Metricbeat, written in Go, provides modules for a variety of services and is extensible for additional ones. The Golang Module for Metricbeat, integrated into the Elastic Stack's master branch and set for release in version 6.0, allows for detailed analysis of Go's memory usage, garbage collection, and potential memory leaks via Kibana dashboards. By enabling Go's expvar service and configuring Metricbeat, users can monitor internal variables and statistics, exposing them as JSON data and allowing for visualization in Kibana. Additionally, Metricbeat can self-monitor its metrics, which can be analyzed using Timelion expressions to assess the stability of data exchanges with Elasticsearch. Users can begin utilizing this module ahead of its official release by accessing the Beats repository on GitHub.
