Logic App Standard - Hello World

This sample will help you get up and running with a hello world for Logic App Standard.

In this scenario we are using the Traces log in App Insights.

Sample Scenario Logic App

In this scenario we have a very simple logic app that will receive a message and do a basic message transformation and return the response.

The input message is shown below.

{
"name":"Joe",
"surname":"Blogs"
}

We will do some tracked properties on the parse json shape which we will try to show in the Turbo360 query.

BAM Queries

There will be a parent and 2 child queries used in this scenario in BAM.

BAM - Parent Query

This query will do a join across some events and do the following:

• Find the workflow start event
• Find the workflow even event
• Link to the parse json shape so we can identify the tracked properties
• Use the KQL project to be able to promote the properties for the grid

let input_LogicAppName = "t360-la-standard-pull-bam";
let input_WorkflowName = "HelloWorld";
let input_ActionName = "Parse_JSON";
let workflowStartEvents = traces
| where cloud_RoleName == input_LogicAppName
| where customDimensions.EventName == "WorkflowRunStart"
| where parse_json(tostring(parse_json(tostring(customDimensions.prop__properties)).resource)).workflowName == input_WorkflowName
| extend runId_ = tostring(parse_json(tostring(parse_json(tostring(customDimensions.prop__properties)).resource)).runId)
| extend workflowName_ = tostring(parse_json(tostring(parse_json(tostring(customDimensions.prop__properties)).resource)).workflowName);
let workflowEndEvents = traces
| where cloud_RoleName == input_LogicAppName
| where customDimensions.EventName == "WorkflowRunEnd"
| where parse_json(tostring(parse_json(tostring(customDimensions.prop__properties)).resource)).workflowName == input_WorkflowName
| extend runId_ = tostring(parse_json(tostring(parse_json(tostring(customDimensions.prop__properties)).resource)).runId)
| extend final_status_ = tostring(customDimensions.prop__status);
let targetActionEvents = traces
| where cloud_RoleName == input_LogicAppName
| where customDimensions.EventName == "WorkflowActionEnd"
| where parse_json(tostring(parse_json(tostring(customDimensions.prop__properties)).resource)).workflowName == input_WorkflowName
| where customDimensions.prop__actionName == input_ActionName
| extend runId_ = tostring(parse_json(tostring(parse_json(tostring(customDimensions.prop__properties)).resource)).runId)
| extend FirstName_ = tostring(parse_json(tostring(parse_json(tostring(customDimensions.prop__properties)).trackedProperties)).FirstName)
| extend LastName_ = tostring(parse_json(tostring(parse_json(tostring(customDimensions.prop__properties)).trackedProperties)).LastName);
workflowStartEvents
| join kind=inner (workflowEndEvents) on runId_
| join kind=inner (targetActionEvents) on runId_
| extend start = timestamp
| extend end = timestamp1
| extend duration = end - start
| project timestamp, WorkflowName = workflowName_, WorkflowRunId = runId_, final_status_, FirstName_, LastName_, start, end, duration
| order by timestamp desc

Child Query 1 - Find Parse Json Action

This query will be used as a child to find the parse json action and then help you light up that shape in your BAM query.

let input_LogicAppName = "t360-la-standard-pull-bam";
let input_WorkflowName = "HelloWorld";
let input_ActionName = "Parse_JSON";
let input_RunId = {WorkflowRunID};
traces
| where cloud_RoleName == input_LogicAppName
| where customDimensions.EventName == "WorkflowActionEnd"
| where parse_json(tostring(parse_json(tostring(customDimensions.prop__properties)).resource)).workflowName == input_WorkflowName
| where parse_json(tostring(parse_json(tostring(customDimensions.prop__properties)).resource)).actionName == input_ActionName
| where parse_json(tostring(parse_json(tostring(customDimensions.prop__properties)).resource)).runId == input_RunId
| extend FirstName_ = tostring(parse_json(tostring(parse_json(tostring(customDimensions.prop__properties)).trackedProperties)).FirstName)
| extend LastName_ = tostring(parse_json(tostring(parse_json(tostring(customDimensions.prop__properties)).trackedProperties)).LastName)
| extend status_ = tostring(parse_json(tostring(customDimensions.prop__properties)).status)

Child Query 2 - Find Response Shape

This query will help you to find the response action log event and then you can light up that shape.

let input_LogicAppName = "t360-la-standard-pull-bam";
let input_WorkflowName = "HelloWorld";
let input_ActionName = "Response";
let input_RunId = "{WorkflowRunId}";
traces
| where cloud_RoleName == input_LogicAppName
| where customDimensions.EventName == "WorkflowActionEnd"
| where parse_json(tostring(parse_json(tostring(customDimensions.prop__properties)).resource)).workflowName == input_WorkflowName
| where parse_json(tostring(parse_json(tostring(customDimensions.prop__properties)).resource)).actionName == input_ActionName
| where parse_json(tostring(parse_json(tostring(customDimensions.prop__properties)).resource)).runId == input_RunId
| extend status_ = tostring(parse_json(tostring(customDimensions.prop__properties)).status)
