Azure-使用带有Metric Measurement参数（非结果计数）的ARM模板部署警报规则

问题描述 投票：0回答：1

我在Azure中部署正确的警报规则有一个小问题。

我的警报是Log Analytics Query，部署正常。但是，当我想要“度量标准”时，我所有的警报都是使用“结果数”创建的。

警报类型

Alert type

我尝试在Azure中创建正确的警报，并在活动日志中使用JSON参数，但我不知道此参数在哪里。

我也在https://docs.microsoft.com/en-us/rest/api/monitor/scheduledqueryrules/createorupdate#alertingaction中搜索，但只说“ ResultCount”。

知道您执行此操作的好参数是什么？

我的template.json

如果要创建日志研究警报，请将Qureytype更改为ResultCount，我们还需要指定触发器，例如"trigger": { "thresholdOperator": "<>", "threshold": 0, "metricTrigger": { "thresholdOperator": "<>", "threshold": 1, "metricTriggerType": "Consecutive", "metricColumn": "<your colum>" }

例如

{
    "$schema": "https://schema.management.azure.com/schemas/2015-01-01/deploymentTemplate.json#",
    "contentVersion": "1.0.0.0",
    "parameters": {
    },
    "variables": {
        "alertLocation": "Region Name for your Application Insights App or Log Analytics Workspace",
        "alertName": "test",
        "alertDescr": "test",
        "alertStatus": "true",
        "alertSource":{
            "Query":"Perf\r\n| where CounterName == \"Free Megabytes\" and InstanceName == \"D:\"\r\n| where TimeGenerated > ago(7d)\r\n| where Computer == \"win2012\"\r\n| summarize AggregatedValue = min(CounterValue) by bin(TimeGenerated, 5m)\n",
