+### How can I set an alert on an event?
+
+Azure alerts are only on metrics. Create a custom metric that crosses a value threshold whenever your event occurs. Then set an alert on the metric. You get a notification whenever the metric crosses the threshold in either direction. You won't get a notification until the first crossing, no matter whether the initial value is high or low. There's always a latency of a few minutes.

+          
+Use the [REST API](/rest/api/application-insights/) to run [Log Analytics](./logs/log-query-overview.md) queries.
+
+### Can I send telemetry to the Application Insights portal?
+
+We recommend that you use our SDKs and use the [SDK API](app/api-custom-events-metrics.md). There are variants of the SDK for various [platforms](app/app-insights-overview.md#supported-languages). These SDKs handle processes like buffering, compression, throttling, and retries. However, the [ingestion schema](https://github.com/microsoft/ApplicationInsights-dotnet/tree/master/BASE/Schema/PublicSchema) and [endpoint protocol](https://github.com/MohanGsk/ApplicationInsights-Home/blob/master/EndpointSpecs/ENDPOINT-PROTOCOL.md) are public.   
+
+### How long does it take for telemetry to be collected?
+
+Most Application Insights data has a latency of under 5 minutes. Some data can take longer, which is typical for larger log files. See the [Application Insights service-level agreement](https://azure.microsoft.com/support/legal/sla/application-insights/v1_2/).

+
+### Can I monitor an intranet web server?
+
+Yes, but you need to allow traffic to our services by either firewall exceptions or proxy redirects:
+
+- QuickPulse `https://rt.services.visualstudio.com:443`
+- ApplicationIdProvider `https://dc.services.visualstudio.com:443`
+- TelemetryChannel `https://dc.services.visualstudio.com:443`
+          
+See [IP addresses used by Azure Monitor](app/ip-addresses.md) to review our full list of services and IP addresses.
+          
+### How do I reroute traffic from my server to a gateway on my intranet?
+          
+Route traffic from your server to a gateway on your intranet by overwriting endpoints in your configuration. If the `Endpoint` properties aren't present in your config, these classes use the default values shown in the following ApplicationInsights.config example.
+          
+Your gateway should route traffic to our endpoint's base address. In your configuration, replace the default values with `http://<your.gateway.address>/<relative path>`.
+          
+#### Example ApplicationInsights.config with default endpoints:
+          
+```xml
+<ApplicationInsights>
+...
+<TelemetryModules>
+    <Add Type="Microsoft.ApplicationInsights.Extensibility.PerfCounterCollector.QuickPulse.QuickPulseTelemetryModule, Microsoft.AI.PerfCounterCollector">
+    <QuickPulseServiceEndpoint>https://rt.services.visualstudio.com/QuickPulseService.svc</QuickPulseServiceEndpoint>
+    </Add>
+</TelemetryModules>
+    ...
+<TelemetryChannel>
+    <EndpointAddress>https://dc.services.visualstudio.com/v2/track</EndpointAddress>
+</TelemetryChannel>
+...
+<ApplicationIdProvider Type="Microsoft.ApplicationInsights.Extensibility.Implementation.ApplicationId.ApplicationInsightsApplicationIdProvider, Microsoft.ApplicationInsights">
+    <ProfileQueryEndpoint>https://dc.services.visualstudio.com/api/profiles/{0}/appId</ProfileQueryEndpoint>
+</ApplicationIdProvider>
+...
+</ApplicationInsights>
+```
+
+> [!NOTE]
+> `ApplicationIdProvider` is available starting in v2.6.0.

 ### How can I disable distributed tracing for the JavaScript SDK?

+
+### Are the HTTP 502 and 503 responses always captured by Application Insights?
+
+No. The "502 bad gateway" and "503 service unavailable" errors aren't always captured by Application Insights. If only client-side JavaScript is being used for monitoring, this behavior would be expected because the error response is returned prior to the page containing the HTML header with the monitoring JavaScript snippet being rendered.
+          
+If the 502 or 503 response was sent from a server with server-side monitoring enabled, the errors are collected by the Application Insights SDK.
+          
+Even when server-side monitoring is enabled on an application's web server, sometimes a 502 or 503 error isn't captured by Application Insights. Many modern web servers don't allow a client to communicate directly. Instead, they employ solutions like reverse proxies to pass information back and forth between the client and the front-end web servers.
+          
+In this scenario, a 502 or 503 response might be returned to a client because of an issue at the reverse proxy layer, so it isn't captured out-of-box by Application Insights. To help detect issues at this layer, you might need to forward logs from your reverse proxy to Log Analytics and create a custom rule to check for 502 or 503 responses. To learn more about common causes of 502 and 503 errors, see [Troubleshoot HTTP errors of "502 bad gateway" and "503 service unavailable" in Azure App Service](../../app-service/troubleshoot-http-502-http-503.md).

+## Frequently asked questions
 
+This section provides answers to common questions.
+
+### Is Application Insights free?
+
+Yes, for experimental use. In the basic pricing plan, your application can send a certain allowance of data each month free of charge. The free allowance is large enough to cover development and publishing an app for a few users. You can set a cap to prevent more than a specified amount of data from being processed.
+          
+Larger volumes of telemetry are charged by the gigabyte. We provide some tips on how to [limit your charges](#application-insights).
+          
+The Enterprise plan incurs a charge for each day that each web server node sends telemetry. It's suitable if you want to use Continuous Export on a large scale.
+          
+Read the [pricing plan](https://azure.microsoft.com/pricing/details/application-insights/).
+
+### How much does Application Insights cost?
+
+* Open the **Usage and estimated costs** page in an Application Insights resource. There's a chart of recent usage. You can set a data volume cap, if you want.
+* To see your bills across all resources:
+
+  1. Open the [Azure portal](https://portal.azure.com).
+  1. Search for **Cost Management** and use the **Cost analysis** pane to see forecasted costs.
+  1. Search for **Cost Management and Billing** and open the **Billing scopes** pane to see current charges across subscriptions.
+          
+### Are there data transfer charges between an Azure web app and Application Insights?
+
+* If your Azure web app is hosted in a datacenter where there's an Application Insights collection endpoint, there's no charge.
+* If there's no collection endpoint in your host datacenter, your app's telemetry incurs [Azure outgoing charges](https://azure.microsoft.com/pricing/details/bandwidth/).
+          
+This answer depends on the distribution of our endpoints, *not* on where your Application Insights resource is hosted.
+
+### Will I incur network costs if my Application Insights resource is monitoring an Azure resource (i.e., telemetry producer) in a different region?
+
+Yes, you may incur additional network costs which will vary depending on the region the telemetry is coming from and where it is going. Refer to [Azure bandwidth pricing](https://azure.microsoft.com/pricing/details/bandwidth/) for details.
