Default Parameters for AzrVmTest

This test auto-discovers the virtual machines used by the target Microsoft Azure subscription, and for each VM, it reveals in-depth metrics such as status, memory utilization, CPU utilization, disk I/O measures, etc. In the process, the test points administrators to resource-hungry VMs.

This page depicts the default parameters that need to be configured for the AzrVmTest.

  • The TEST PERIOD list box helps the user to decide how often this test needs to be executed.

  • Specify the GUID which uniquely identifies the Microsoft Azure Subscription to be monitored in the SUBSCRIPTION ID text box.To know the ID that maps to the target subscription, click here.

  • Specify the Directory ID of the Azure AD tenant to which the target subscription belongs in the TENANT ID text box. To know how to determine the Directory ID/Tenant ID, click here.

  • The eG agent communicates with the target Microsoft Azure Subscrption using Java API calls. To collect the required metrics, the eG agent requires an Access token in the form of an Application ID and the client secret value.Specify the Application ID of the created Application in the CLIENT ID text box. To know how to determine the Application ID ,click here. Specify the client secret value in the CLIENT PASSWORD text box. To obtain the client secret value, click here.

  • Confirm the CLIENT PASSWORD by retyping it in the CONFIRM PASSWORD text box.

  • In some environments, all communication with the Azure cloud be routed through a proxy server. In such environments, you should make sure that the eG agent connects to the cloud via the proxy server and collects metrics. To enable metrics collection via a proxy, specify the IP address of the proxy server and the port at which the server listens against the PROXY HOST and PROXY PORT parameters. By default, these parameters are set to none , indicating that the eG agent is not configured to communicate via a proxy, by default.

  • If the proxy server requires authentication, then, specify a valid proxy user name and password in the PROXY USERNAME and PROXY PASSWORD parameters, respectively. Then, confirm the password by retyping it in the CONFIRM PASSWORD text box.

  • By default, Diagnostic Measures flag is set to Off. This means that, by default, this test reports only host-level metrics - eg., CPU usage, disk usage, and network usage - for each VM.

    For deeper insights into VM performance, you may want to collect guest-level metrics and other diagnostic data using the Azure Diagnostics extension. Azure Diagnostics extension is an agent in Azure Monitor that collects monitoring data from the guest operating system of Azure compute resources including virtual machines. To configure this test to use this extension and pull guest-level metrics from VMs, do the following:

    1. Install the Azure Diagnostics Agent on each VM you want guest-level metrics from. To achieve this, click here

    2. Set the DIAGNOSTIC MEASURES flag of this test to On.

  • Once the necessary values have been provided, clicking on the UPDATE button will register the changes made.

When changing default configurations of tests, the values with “$” indicate variables that will be replaced by the eG system according to the specific server being managed - for instance, $hostName is the host/nickname of the target host, $port is the port number of the server being monitored. E.g., for a server xyz:80, $hostName will be changed automatically by the eG manager to “xyz*” and $port will be changed to “80” when configuring a test.
