# Monitors

This topic describes how to create and configure monitor profiles, which can be used by any performance test in your project, to monitor server resources during a performance test run.

In this topic:

## Monitors overview

You monitor performance test runs using the online monitors. The collected measurement data is displayed in the online graphs during a test run, and a summary is available at the conclusion of the performance test.

The online monitors are divided into:

- Monitors enabled by default. These monitors automatically begin monitoring at the start of a performance test.

- Monitors requiring configuration. To monitor server resources, you must configure the monitor settings for a performance test. You select the type of monitors to run, the servers whose resources you want to monitor, and add the measurements to monitor for each server. These monitor settings can then be saved as a monitor profile that can be used by any performance test in your project.

You can also use Analysis, the OpenText Professional Performance Engineering tool for gathering and presenting load test data, for any of the monitors. Analysis provides graphs and reports, enabling you to view and understand the data, and analyze system performance after a test run. For details, see the OpenText Professional Performance Engineering Help Center.

Note: When configuring a monitor, refer to the Support Matrix for a list of the supported server name formats, such as IPv4, IPv6, or FQDN.

## Create a monitor profile

This task describes how to create and configure a monitor profile.

Prerequisites

Requirement | Description
--- | ---
Configure the monitoring environment on the server machine | To use the Citrix, Network Delay Time, Oracle, or UNIX monitor, you must first install or configure monitoring components on the server machine. For details, see the specific monitoring sections.
Use a proxy server | If your monitor accesses a server outside of your internal network, you may need to set up a web proxy to collect data from it. To do this: Open the following files in a text editor: For a server: bin\MEApplication.exe.config and PCWEB\Web.config For a host: bin\wlrun.exe.config and add the following under the configuration > system.net section of the file: <system.net> <defaultProxy enabled="true"> <proxy proxyaddress="http://<PROXY_ADDRESS>:<PORT>" bypassonlocal="True" /> </defaultProxy> </system.net> Restart IIS after adding the proxy in the PCWEB\Web.config file (type 'iisreset' in a command line).

Step 1: Select or create a resources folder

In the resources tree, select a resources folder for the monitor profile or create a new folder.

To create a new resources folder:

1. Click the Navigation menu and select Assets > Monitors.

2. In the resources tree, select a folder in which you want to add the new folder.

3. Click the New Folder button and enter a name for the monitor resources folder.

Step 2: Create a monitor profile

1. Select the folder in which you want to add the monitor, and click the New Monitor Profile button . Make sure Monitor Profile is selected.

2. Enter a name and description (optional) for the monitor profile, and click OK. An empty monitor profile is added to the selected resources folder.

   You can add or edit the monitor profile description at any time by clicking the Asset Description button . A notification dot indicates that the profile has a description.

3. Select the monitor profile you just added and click the New Monitor button . Select the monitor type that you want to add, and click Next. For the list of available monitors, see Monitors requiring configuration.

## Troubleshoot monitors

This section provides information on troubleshooting monitors.

Problem | Cause / Resolution
--- | ---
Unable to create a monitor | Make sure that the user trying to access the machine to monitor exists on this machine and has proper permissions. Usually IUSR_METRO is the user attempting to monitor. For example, if you add the Windows Resources monitor, the user IUSR_METRO must exist on the machine to be monitored and must have proper access rights. Some monitors require specific clients to reside on the Utility Server and the Controller. For Oracle, the Oracle Client must be installed. Make sure the agent required for a monitor is running on the machine that you want to monitor. Some monitors require access to a URL from both the utility server and the Controller, for monitoring purposes. For Apache, this URL is: `http://<server>:<port>/server-status:auto`
Monitor fails to retrieve measurements | This problem can occur with Windows Resource, Microsoft IIS, SQL Server, or Microsoft ASP monitors when: Configuring a monitor (when you click Get Counters) Running a test (for example, if you have created a monitor profile and then change the system user and run the test). An error is displayed in the Errors window, and no data is displayed in the monitor's online graphs. Cause: The server sends messages to the monitored server using the SMB2 protocol. This protocol uses the supplied user credentials for the session initialization. However, the monitored machine sends another authentication request to the client, and the client sends the credentials of the user running the process that initiated the connection (the system user account, or IUSR_METRO by default). If that user account does not exist on the remote server, authentication fails and the user that is being used for authentication and metrics retrieval is the one whose user name and password are provided when creating the monitor. If the system user account exists on the monitored server, but is not a local admin on the remote server (or does not have the required permissions), the initial authentication succeeds, but retrieving the metrics from the remote server fails because the credentials provided when creating the monitor are not being used. Resolution: Remove the system user from the monitored machine, or Deny access of the system user to the monitored machine from Local security policy > User rights assignment > Deny access to this computer from the network.
Some monitors do not display data | Cause: This problem can occur with PDH monitors, which include Windows Resources, MS IIS, SQL Server, Citrix Server, and Microsoft ASP. These monitor require a NET USE connection to retrieve measurement data. When you select measurements or counters to monitor, the MonitorClient.exe process on the LoadRunner Agent machine uses the logged in user’s NET USE to connect to the application under test (AUT). However, during the performance test run, the LoadRunner Agent invokes the MonitorServer.exe process to retrieve data from the AUT using the local user, IUSR_METRO. This means there is no NET USE connection between the Monitor Over Firewall machine and the AUT during the test run, resulting in no measurement data being received on the PDH monitors. Resolution: Ensure that the magentservice.exe on the Monitor Over Firewall machine is installed with the same user that you used to log on when you selected measurements or counters to monitor. Perform the following steps on the Monitor Over Firewall Machine: Stop the Agent Service. From the Start menu, enter `services.msc`. In the services list, right-click Agent Service and select Stop. Enter the following in the Command window and press Enter: cd <monitor_over_firewall_installdir>\launch_service\bin Enter the following and press Enter: magentservice –remove Enter the following and press Enter: magentservice –install <Logged on user name> <Password> Restart the Agent Service using the same procedure described in step 1.
Deactivating automatic host monitors | Cause: The host monitors feature automatically configures basic Windows monitor data for all the machines involved in a performance test (except for Dockerized and Cloud load generators and OFW machines). This data (CPU, disk space, and memory) is available during a performance test run in the online graphs, or afterwards when collating and analyzing the results. In environments where the network ports are closed, this feature may cause a significant slowdown when starting a performance test run. Resolution: Deactivate the host monitors. In the Groups and Workload tab, click the Test Options button , and select Disable Default Monitors in the General section.
