Documentation forServer & Application Monitor
Monitoring your applications and environment is a key capability of Hybrid Cloud Observability and is also available in a standalone module, Server & Application Monitor (SAM). Hybrid Cloud Observability and SAM are built on the self-hosted SolarWinds Platform.

Asset Inventory polling requirements

This topic also applies to SolarWinds SCM, which supports Asset Inventory polling.

To configure SAM to collect Asset Inventory data:

SAM can also collect warranty data, display it on the SAM Summary page, and notify you about pending expiration dates, see Display the warranty status for physical servers in SAM.

Supported physical servers

SAM supports Asset Inventory data collection for the following systems. Additional servers may be supported with a limited amount of data returned by polling.

Supported operating systems and protocols

OS Protocol





AIX v7 and higher



Click here to learn about versions supported by SAM, which sync with VMAN.

Common Information Model (CIM), VMware API

Use ICMP for VMware nodes not polled by CIM or the VMware API.

VMware API for ESX/ESXi hosts polled via vCenter


If the vCenter API is slow to report changes, use CIM to monitor each host directly.

Ports used for Asset Inventory polling

Port Protocol Service/Process Direction Notes
135 TCP Microsoft EPMAP (DCE/RPC Locator service) Bidirectional

WMI agentless polling.

WMI uses port 135 to initiate communication with remotely managed hosts, then switches to a random port between 1024 and 65535.

161 UDP

SolarWinds Job Engine v2


SNMP agentless polling

445 TCP File and Printer Sharing (SMB-In) Bidirectional

WMI agentless polling.

Asset Inventory uses VBScript to gather data about Windows updates on monitored nodes, which may cause false-positive alerts in antivirus scans. If you need to disable VBScript, see this article.
