Thank you for reaching out. Based on my understanding from your question above you want to know the description for the metrics captured by your logs. If I understand it correctly you are using Azure APIM resource, you can go through this document to get the description for each of the metrics described above.
Like for example NetworkConnectivity
represents the Network Connectivity status of dependent resource types from API Management service.
Based on your question above.
the objective is i want to understand the cpu and memory utilization of my resources and get details from azure logs as AzureMetrics . how can i do that ?
Given the Azure resource you are using, if in this case if you are using Azure APIM then the Capacity metric will give you the required information as this metric ranges from 0-100 calculated based on gateway resources such as CPU and memory utilization. You can go through this documentation for additional details.
Hope this helps! Please let me know if you have any additional questions here.
