Azure App Service - monitoring application behavior (and using custom metrics)

Setup

Configure your target App Service in pom.xml

<resourceGroup>...</resourceGroup>
<appName>...</appName>
<subscriptionId>...</subscriptionId>

Set APPINSIGHTS_INSTRUMENTATIONKEY in your Azure App Service Application settings

Provide log message in your Azure App Service Application settings

Configure your Azure deployment credentials on maven settings.xml

	<server>
		<id>azure-auth</id>
		<configuration>
			<client>...</client>    
			<tenant>...</tenant>
			<key>...</key>
			<environment>AZURE</environment>
	  </configuration>
    </server> 

Configure proxy (if required) As you configure your Java project for ApplicationInsights to allow maven download dependencies you can set maven proxies in your settings.xml (e.g. in %USERPROFILE%/.m2)

  <proxies>
	 <proxy>
	  <id>mgsproxy</id>
	  <active>true</active>
	  <protocol>http</protocol>
	  <host>xx.xx.xx.xx</host>
	  <port>nnnn</port>
	</proxy>
  </proxies>

Deploy your application and Monitor your log messages and metrics in Azure Application Insights

Query Examples

1. Find recent log messages with specific sub-string:

traces | where timestamp > ago(1h) | where message contains 'build' | sort by timestamp desc

2. Find count of recent request for each error HTTP code:

requests | where timestamp > ago(1h) | summarize count() by resultCode

3. Find recent http errors:

requests | where timestamp > ago(1h) | where toint(resultCode) >=400 and toint(resultCode) != 401 | sort by timestamp desc

4. Find recent 5xx errors:

requests | where timestamp > ago(1h) | where toint(resultCode) >=500 | sort by timestamp desc 

5. Find recent exceptions for specific app (can use cloud_RoleName as filter):

exceptions | where timestamp > ago(1h) | where cloud_RoleName  == 'springapitest0003' 
| sort by timestamp desc 

Note: The cloud_roleName is taken from spring.application.name in application.properties.
