Thank you for the question and for using Microsoft Q&A platform.

It seems like you're trying to get the count of messages in each partition of your Event Hub topic. Unfortunately, Azure Diagnostics doesn't provide a way to achieve this. Only certain metrics are supported by the Azure Monitor for Event Hubs:
https://learn.microsoft.com/en-us/azure/azure-monitor/reference/supported-metrics/microsoft-eventhub-namespaces-metrics

You can count the number of incoming messages using the Metrics section:

In the logs, you can have all the columns mentioned in this document: https://learn.microsoft.com/en-us/azure/azure-monitor/reference/supported-metrics/microsoft-eventhub-namespaces-metrics

There is no column named Partition_ID. Hence, we cannot achieve this using Azure Monitor.

For more information, please refer to the below link:

Hope this helps. Do let us know if you have any further queries.
