+Выполнение [домашнего задания](https://github.com/netology-code/mnt-homeworks/blob/MNT-13/10-monitoring-03-grafana/README.md)
+по теме "10.3. Системы Grafana"
+
+## Q/A
+
+### Задание 1
+
+> Cамостоятельно разверните grafana, где в роли источника данных будет выступать prometheus, а сборщиком данных node-exporter:
+> 
+> * `grafana`
+> * `prometheus-server`
+> * `prometheus node-exporter`
+> 
+> Запустите связку prometheus-grafana.
+> Зайдите в веб-интерфейс Grafana, используя авторизационные данные, указанные в манифесте docker-compose.
+> Подключите поднятый вами prometheus как источник данных.
+> Решение домашнего задания - скриншот веб-интерфейса grafana со списком подключенных Datasource.
+> В решении к домашнему заданию приведите также все конфигурации/скрипты/манифесты, которые вы использовали в процессе решения задания.
+
+`docker-compose` и остальная конфигурация расположена в директории [stack](./stack).
+При поднятии контейнеров в `grafana` автоматически создаётся `data-source` к `prometheus`,
+а так же dashboard по мониторингу контейнера `prometheus`.
+
+![grafana_datasource](./img/grafana_datasource.png)
+
+### Задание 2
+
+> Изучите самостоятельно ресурсы:
+> - [promql-for-humans](https://timber.io/blog/promql-for-humans/#cpu-usage-by-instance)
+> - [understanding prometheus cpu metrics](https://www.robustperception.io/understanding-machine-cpu-usage)
+> 
+> Создайте Dashboard и в ней создайте следующие Panels:
+> - Утилизация CPU для nodeexporter (в процентах, 100-idle)
+> - CPULA 1/5/15
+> - Количество свободной оперативной памяти
+> - Количество места на файловой системе
+> 
+> Для решения данного ДЗ приведите promql запросы для выдачи этих метрик, а также скриншот получившейся Dashboard.
+
+Метрики и текст запросов для них
