Metrics collector service

The service collects a number of metrics from runtime and sends them furter to http://<HOST>/update/<METRIC_TYPE>/<METRIC_NAME>/<VALUE> and "application-type": "text/plain"

Metrics collector service

• Metrics types
• Metrics list
• Global variables
• Service quit signals

Metrics types

• gauge, float64
• counter, int64

Metrics sourse: runtime

• "PollCount", counter — conter incremted by 1, every time metrics are updated from runtime (every pollInterval — see below).
• "RandomValue", gauge — updated random value.

Global variables

• pollInterval - how oftem metrics are updated (every 2s)
• reportInterval - how often metrics are sent (every 10s)

Service quit signals

• syscall.SIGTERM
• syscall.SIGINT
• syscall.SIGQUIT

Обновление шаблона

Чтобы получать обновления автотестов и других частей шаблона, выполните следующую команду:

git remote add -m main template https://github.com/yandex-praktikum/go-musthave-devops-tpl.git

Для обновления кода автотестов выполните команду:

git fetch template && git checkout template/main .github

Затем добавьте полученные изменения в свой репозиторий.
