Golang Metrics

To get started first follow the steps below:

• Install
• Root access
• Verify the required port is open

Older versions can be found here 7, 6, 5

The configuration file below is pre-configured to send data to your Logit.io Stack via Logstash.

Copy the configuration file below and overwrite the contents of metricbeat.yml.

###################### Logit.io Metricbeat Configuration #######################
# =========================== Modules configuration ============================

  # Period on which files under path should be checked for changes
  #reload.period: 10s

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

deb/rpm

metricbeat modules list
metricbeat modules enable golang

macOS

./metricbeat modules list
./metricbeat modules enable golang

Windows

PS > .\metricbeat.exe modules enable golang

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

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

deb/rpm /etc/metricbeat/modules.d/golang.yml

mac/win ~/<EXTRACTED_ARCHIVE>/modules.d/golang.yml

By default the following 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 or restart to apply the configuration changes.

If you don't see data appearing in your Stack after following the steps, visit the Help Centre guide for steps to diagnose no data appearing in your Stack or Chat to support now.

The Golang module comes with predefined Kibana dashboards. To view your dashboards for any of your Logit.io stacks, launch Kibana and choose Dashboards.
