Создание нескольких оповещений для Azure Log Analytics и критериев на основе метрик с помощью Azure PowerShell?

0 голосов
/ 31 августа 2018

Предполагается, что я подготовил один общий файл шаблона для Azure для создания предупреждений на основе метрик, и у меня есть 2 отдельных файла параметров для 2 различных метрических предупреждений (например, загрузка ЦП, использование памяти).

Пожалуйста, обратитесь к моему примеру файла шаблона ниже и к команде, которую я намереваюсь выполнить для создания этих 2 типов предупреждений через Powershell.

Есть ли лучший / более элегантный способ сделать это по-другому (одна строка командной строки)? Я считаю ненужным создавать еще одну пару файлов для разных виртуальных машин, которые я хочу отслеживать.

Сообщите мне, есть ли какая-либо документация, на которую я могу сослаться на это на веб-сайте Azure.

Команда Azure CLI:

az group deployment create --name AlertTemplateDeployment --resource-group TestRscGrp --output tsv --template-file common_metricalert.template.json --parameters cpu_metricalert.parameters.json

az group deployment create --name AlertTemplateDeployment --resource-group TestRscGrp --output tsv --template-file common_metricalert.template.json --parameters memory_metricalert.parameters.json
