Enable Module

There are several built-in metricbeat modules you can use. To enable the golang module, run the following:

metricbeat modules list
metricbeat modules enable @module

The golang module collects metrics by submitting HTTP GET requests to golang-expvar-api.

Configure Module

Each module has its own configuration file where different metricsets can be enabled / disabled. Locate the configuration file for the golang module.

/etc/metricbeat/modules.d/@module.yml

By default metricsets are disabled. To enable or disable a metric simply comment or uncomment the line out.

- module: golang
  #metricsets:
    # - expvar
    # - heap
  period: 10s
  hosts: ["localhost:6060"]
  heap.path: "/debug/vars"
  expvar:
    namespace: "example"
    path: "/debug/vars"

Start Metricbeat

Start or restart Metricbeat (opens in a new tab) to apply the configuration changes.

Check Logit.io for your logs

Data should now have been sent to your Stack.

Golang Metricbeat Module Overview

The Metricbeat Module for Golang is a targeted tool designed for the comprehensive monitoring of Golang applications by capturing essential metrics. Those who have previously engaged with Metricbeat's data collection capabilities across different services will find its adaptation to Golang both intuitive and highly effective.

Golang, or Go, is celebrated for its efficiency, concurrency support, and ease of use in developing scalable and high-performance applications. The Metricbeat Module for Golang connects to the Go runtime to extract valuable metrics such as garbage collection statistics, memory allocation, and goroutine counts, offering deep insights into application performance and health.

This module has quickly become indispensable for developers, DevOps engineers, and system administrators who manage Golang applications, thanks to its easy configuration and the seamless integration with the ELK Stack (opens in a new tab). This combination unlocks real-time monitoring and analytical capabilities, providing a level of insight and operational visibility that greatly exceeds that of conventional monitoring tools.

Unlike other monitoring solutions that may rely on custom or rigid data formats, the Metricbeat Module for Golang is crafted to simplify the analysis, troubleshooting, and monitoring of Golang applications, ensuring ease of use and comprehensive coverage.

Our platform supports the Metricbeat Module for Golang, providing centralized metrics management (opens in a new tab) designed for effortless analysis and proactive monitoring. This eliminates the challenges associated with manually aggregating and interpreting metrics across distributed Golang applications.

If you require assistance with configuring the Metricbeat Module for Golang or have questions about monitoring your Golang applications, the Logit.io team is prepared to assist. We invite you to visit our Help Centre or reach out to our support team via live chat and we'll be happy to assist.
