Send some of the properties to slack from azure alerts - azure

Question

How can I send some of the properties from AzureMonitorMetricAlert
The full JSON looks like:
{
"schemaId":"AzureMonitorMetricAlert",
"data": {
"version":"2.0",
"properties":null,
"status":"Active",
"context": {
"timestamp":"2019-04-30T14:19:49.4987935Z",
"id":"/subscriptions/xxxxxxxx/resourceGroups/test/providers/microsoft.insights/metricAlerts/500%20response%20code",
"name":"500 response code",
"description":"",
"conditionType":"DynamicThresholdCriteria",
"severity":"3",
"condition": {
"windowSize":"PT5M",
"allOf": [
{
"alertSensitivity":null,
"failingPeriods":null,
"ignoreDataBefore":null,
"metricName":"requests/failed",
"metricNamespace":"microsoft.insights/components",
"operator":null,
"threshold":null,
"timeAggregation":"Count",
"dimensions": [
{
"name":"ResourceId",
"value":"xxxxxxxxx"
},
{
"name":"request/resultCode",
"value":"500"
}
],
"metricValue":null
}
]
},
"subscriptionId":"xxxxxxxxxxxxxxxx",
"resourceGroupName":"test",
"resourceName":"test",
"resourceType":"microsoft.insights/components",
"resourceId":"/subscriptions/xxxxxxxxxxx/resourceGroups/test/providers/microsoft.insights/components/tests",
"portalLink":"https://portal.azure.com/#resource/subscriptions/xxxxxxxx/resourceGroups/dsdsdsdsds"
}
}
}
How can I send message to the slack including text eg: "The alert for ${context.name} was sent."
I was trying with:
"actions": {
"Post_message": {
"inputs": {
"host": {
"connection": {
"name": "#parameters('$connections')['slack']['connectionId']"
}
},
"method": "post",
"path": "/chat.postMessage",
"queries": {
"channel": "CHT0EMJ3H",
"parse": "full",
"text": "tests::::::=>>>>> #{triggerBody()?['context']['name']}"
}
},
"runAfter": {},
"type": "ApiConnection"
}
}
But it doesn't work. If I use just "text": "tests::::::=>>>>> #{triggerBody()}" the full JSON is sent but it is hard to read it since it is parsed as a string.

Answer 1

You can't read the properties because the output of triggerbody() is a string. so you could parse the string to Json firstly then read the properties.
So you need to use the Parse Json action, the Content is the #triggerBody() and the schema click Use sample payload to generate schema and input the Json. With this action you will be able to read the properties.
I test with HTTP Request trigger and send an mail, reading the conditionType with #{body('Parse_JSON')?['data']?['context']?['conditionType']}.
