Problem

I don't see metric data in my Azure monitoring setup

Resolution

If you have missing or wrong metrics:

Verify the charts in Azure Portal Monitor with Dynatrace Data explorer.
Make sure that you compare the same periods.
Make sure you compare data with the same resolution in Azure and Dynatrace (for example, one data point per minute, 12:43-12:44). We recommend that you compare data with a one-minute resolution whenever possible.
Make sure that you compare granular data split across as many dimensions as possible (Azure: filter/split by).
Make sure that you compare the same type of aggregated data (average with average, minimum with minimum, maximum with maximum).

Check aggregation functions. If the detailed data shows no discrepancies, you can assume that the underlying data from Azure was imported correctly. Any differences observed when viewing less detailed, aggregated data can result from the method used to group the data over time (SUM/AVG/MIN/MAX) or over dimensions (for example, merging data from multiple combinations of dimension values into a single data point).

Example 1: Five data points representing a one-minute period can be aggregated into a single data point for a five-minute period.
Example 2: Data from various regions (such as "region=east-us, responseStatus=400", "region=west-us, responseStatus=200") can be combined into a single data point representing the total number of responses across all regions.

If Monitoring by tags is enabled:

Ensure missing resources have tags specified in the "Include Tags" filter.
Ensure target resources don't have tags from the "Exclude Tags" filter.
Ensure that the "Capture Azure Tags Automatically" toggle is turned on.
You need to tag parent resources for certain services to retrieve all metrics. For example, an SQL Server must have the same tags as an SQL Database.

Thanks @piotr_szwarc for these tips. Especially useful is the point: "Check aggregation functions".

When comparing individual data points between Azure and Dynatrace within the same timeframe, with a one-minute resolution and consistent dimensions, if the data points align, it indicates that the metric capture process is functioning correctly and the data points are accurate.

However, disparities may arise when comparing aggregated data. This occurs because Dynatrace captures specific data points from Azure every minute rather than aggregating data directly from Azure itself. As a result, variations in aggregated data can occur.

It is worth mentioning that when Microsoft sends a singular value, such as a count representing a metric, it's interpreted as a "Total" on the Dynatrace platform. Therefore, the aggregation method on the Dynatrace side should be set to "Sum," even if the corresponding method on the Azure side is "Count."

For example,

Azure Cosmos DB Account (GlobalDocumentDB)

metric: ext:cloud.azure.microsoft_documentdb.databaseaccounts.totalrequests

For individual data points:

For aggregated data:

@IrynaKudlaienko

I'm facing an issue, post OA installation on my Web app network metrics data like "Traffic, Disk throughput" are not coming up.

Web app is active and functioning, even there were some traffic created by the application team to replicate but nothing appearing on the console.

Thanks
