How to see the amount of daily storage used in Azure Application Insights

Nelson 0 Microsoft Vendor

In Azure application insights - how do I see how much of the daily usage I've used?

I can see that I can set a daily cap - but I don't know how much I've used or if I'm near the cap.

Have checked around the dashboard, there are options to set daily cap but no option I can find to see the daily usage metric.

In Azure Application Insights, while there is no direct out-of-the-box feature to view daily usage metrics from the Azure Portal dashboard, you can monitor your daily usage through the Metrics and Usage features. Here's how to check your daily usage:

Go to the Azure portal and navigate to your Application Insights resource.

In the left-hand menu, click on Metrics. This will allow you to create a metric chart.

In the Metrics pane, select the Metric Namespace as Availability and then choose Data Volume. This metric represents the volume of data sent to Application Insights.

Adjust the time range to Last 24 hours to view your usage over the past day. You can also set a specific granularity to see usage trends more clearly (e.g., hourly).

Review the graph and values displayed to assess how much data you have consumed in the selected period.

Under "Metrix Namespace" I only see "Log-based Metrics" and "Application Insights Standard". The closest metric which only exists under "Log-based metrics" to "Data Volume" is "Data point volume" - and this returns back an empty chart:

Any ideas?

Assuming that you're using the Application Insights standard telemetry data schema, you can use the following tables, which are generally present:

requests: This table records telemetry about incoming requests.

dependencies: This table records telemetry about external service calls.

traces: This table records telemetry about traces or logs.

exceptions: This table records telemetry about exceptions.

You can calculate the total data volume sent in the last 24 hours using the size of the telemetry. Unfortunately, Azure Application Insights does not provide a built-in column that directly states the size of each event.

Here’s how to create queries for the above tables:

For Request Volume:
requests | where timestamp >= ago(1d) | summarize TotalRequests = count()

For Exception Volume:
exceptions | where timestamp >= ago(1d) | summarize TotalExceptions = count()

For Dependencies Volume:
dependencies | where timestamp >= ago(1d) | summarize TotalDependencies = count()

If you need to estimate the data volume based on the count of events (assuming an average size per event), you can do something like this:

union requests, dependencies, exceptions, traces | where timestamp >= ago(1d) | summarize TotalEvents = count() | extend EstimatedDataVolumeBytes = TotalEvents * <average_size_in_bytes>

Replace <average_size_in_bytes> with the average size of a telemetry event, which you might estimate based on your application's logging patterns.
