Why am I seeing multiple metrics with same name in application insights?

In an application insight created for an app service, I am seeing multiple metrics of the same type. Eg: Operation_Name, Operation name, Operation__name, etc This same behavior is visible in various other metrics. Could you please tell me why would that happen?

    @Rashmi Gupta - Welcome to Microsft Q&A and thanks for reaching out to us.

    If you are seeing multiple metrics with the same type of aggregation, it is likely that you are seeing both log-based metrics and pre-aggregated metrics or you are seeing multiple metrics with similar names due to differences in casing or spacing of metric names.

    Both log-based and pre-aggregated metrics coexist in Application Insights. To differentiate the two, in the Application Insights user experience the pre-aggregated metrics are now called Standard metrics (preview) The traditional metrics from the events were renamed to Log-based metrics**.**

    You can use the Metrics Explorer to view and analyze both log-based and pre-aggregated metrics. You can also use the Metrics API to retrieve metrics programmatically.

    To differentiate between metrics with similar names, you can use the Metrics Explorer to view the full metric name and its dimensions.

    For more information, please refer to the document : https://learn.microsoft.com/en-us/azure/azure-monitor/app/pre-aggregated-metrics-log-metrics

    Hope this helps. and please feel free to reach out if you have any further questions.
