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

  • gauge, float64
  • counter, int64

Metrics sourse: runtime

Metrics list

  • "Alloc", gauge
  • "BuckHashSys", gauge
  • "Frees", gauge
  • "GCCPUFraction", gauge
  • "GCSys", gauge
  • "HeapAlloc", gauge
  • "HeapIdle", gauge
  • "HeapInuse", gauge
  • "HeapObjects", gauge
  • "HeapReleased", gauge
  • "HeapSys", gauge
  • "LastGC", gauge
  • "Lookups", gauge
  • "MCacheInuse", gauge
  • "MCacheSys", gauge
  • "MSpanInuse", gauge
  • "MSpanSys", gauge
  • "Mallocs", gauge
  • "NextGC", gauge
  • "NumForcedGC", gauge
  • "NumGC", gauge
  • "OtherSys", gauge
  • "PauseTotalNs", gauge
  • "StackInuse", gauge
  • "StackSys", gauge
  • "Sys", gauge
  • "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.
