Install Remote Probes
A probe is a lightweight Windows service installed on a network to collect hardware and software details of devices within that network.
ServiceDesk Plus Cloud relies on the probe-server architecture for device scanning. Therefore, to scan devices in your organization's networks or domains, install the probe on a Windows machine within each network or domain you want to scan.
When a scan is initiated, the central server (ServiceDesk Plus Cloud) assigns the scan as a job to the associated probe via data management server (DMS). The probe executes the job, collects the device details, and sends them to the central server to add as assets. When a device is scanned again, the probe sends only the changed details to minimize bandwidth usage.
Every five minutes, the probe contacts the central server to update its status and check for new scans. Scans initiated while a job is in progress are queued and picked up at the next contact.
The communication between the probe and the central server is secured over HTTPS.
Probe Architecture

You can also configure probes in custom widgets to establish a connection between probe and third-party application.
Minimum system requirements to install probe:
- Operating System: Windows Server 2012 or later, Windows 10 or later
- Dependent Software: .NET Framework 4.8 or later
- Hardware Requirements: 4GB of RAM, Processor Speed of 1.80 GHz, and Hard Disk space of 5GB.
- Supported Communication Protocol: HTTPS with TLS 1.2 and later must be enabled, and older protocols (TLS 1.1) must be disabled.
URLs and ports to be whitelisted for probe:
- Ports: 443 (HTTPS), 5454 (if self-scan is used via probe)
- ServiceDesk Plus Cloud URLs: Click here for the list of URLs to be whitelisted.
- Data management server (DMS) URLs: Click here for the list of DMS domain URLs to be whitelisted.
The maximum number of probes that can be created is based on the number of purchased node licenses.
You can create one probe for every 50 nodes. However, each probe can scan all devices included in the assigned scan job and is not limited to the number of licensed nodes.
