Hi @Cloud_Geek_82

Thank you for reaching out to the Microsoft Q&A platform.

As suggested by Olaf, to monitor the CPU and RAM usage of a Linux VM in Azure, you can use Azure Monitor. Here are the steps to find the maximum CPU and RAM usage for a certain period of time:

1. Open the Azure portal and navigate to the virtual machine that you want to monitor.
2. Click on the "Metrics" blade in the left-hand menu.
3. In the "Metrics" blade, select the "Percentage CPU" metric and the "Memory Usage" metric.
4. Set the time range to the period you want to monitor (from 8AM till 6PM).
5. Click on the "Chart options" button and select "Max" as the aggregation type.
6. Click on the "Apply" button to update the chart.
7. You can now see the maximum CPU and RAM usage for the selected period of time.

Alternatively, you can use the Azure Monitor REST API to collect the CPU and RAM usage data for the VM. You can use the following GET request to collect the CPU and RAM usage data: GET https://management.azure.com/subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.Compute/virtualMachines/{vmName}/providers/microsoft.insights/metrics?api-version=2018-01-01&metricnames=Percentage CPU,Memory Usage&timespan=2018-06-05T03:00:00Z/2018-06-07T03:00:00Z Replace the {subscriptionId}, {resourceGroupName}, and {vmName} placeholders with the appropriate values for your VM. The timespan parameter specifies the period of time you want to monitor.
