Monitoring from global distributed locations helps to see your applications as perceived by your end-user community. However, in some situations, companies would like to check response times and availability of their application within their local network. There are two cases in which customers decide to use a private agent:
- The application under monitoring is not available from the Internet.
- Performance and uptime comparison – LAN vs. WAN.
Both are good reasons and therefore we provide a Private Agent that can be installed on a dedicated Windows Server within your data center. Once the private agent has been installed you can configure monitoring devices to be executed on this internal private agent.
This guideline walks you through all steps required to prepare the installation, execute the setup and configure your devices to use the private agent. Additionally, it provides some answers to frequently asked questions.
- 2-core CPU or higher
- 16 GB RAM
- 2 GB Hard Drive space
- OS Windows Server 2008 R2 or higher x 64bit
- .NET Framework 4.7
- Windows Media Player (for Streaming Media tasks only)
- Remote Desktop service enabled on the machine (for UserView/BrowserView tasks only)
- Administrative Access for installation and execution
We highly recommend using a dedicated Windows Server for your private agent installation. Depending on the number of monitoring devices you are going to simulate on your private agent, the load can be high and can have an impact on CPU or Memory utilization of this server.

Question: Why are there 5 Dotcom-Monitor Private Agent Services?
Question: Why is there a new DotcomMonitorRdpUser on my Window Server?
Question: Will this DotcomMonitorRdpUser block a Client RDP License?
Question: How many Private Agents will be required?
Those services are used for executing monitoring devices on your new Private Agent. After the installation, one of those is running and the other four are in the Manual Start Type. Each of those services can run a single monitoring device in parallel. If you configure multiple monitoring devices to run on your Private Agent those services will be started and used to execute your devices.
This user has been created during the private agent installation. It will be used for the communication with the dotcom-monitor private agent services and is required for the execution of monitoring devices on your private agent server
Our DotcomMonitorRdpUser will block one RDP License. After the private agent has been installed you won’t be able to establish two parallel RDP connections to your private agent server.
Avoid overload situations. If you configure 20 devices to run on a 5-minute frequency and each device will take 5 minutes to complete, the Private Agent won’t be able to execute those. The number of Private Agents required depends on:
- Execution Frequency
- Execution Duration of your Devices
# Private Agents = ((# Devices * Duration (min)) * (1 / Frequency (min)) / 5 Devices in parallel
5-minute Execution Frequency
5-minute session time of each device (Duration)
# Private Agents = ((20 * 5)*(1 / 5) / 5 = 4 PA will be required
