Feature availability based on monitoring methods — with agents or agentless using SNMP, WMI, or WinRM

This article provides a comparison of which features are available for the Windows agent versus agentless. SNMP is typically used to monitor servers and network devices without agents. For Windows servers, Windows Management Instrumentation (WMI) can usually provide a better set of metrics than can be obtained through SNMP monitoring alone. For many Windows-based servers and applications, agentless monitoring via the WMI gateway provides strong monitoring capabilities.

The availability of some features depends on which Orion Platform modules are in your environment, as well as which product versions you're using. For example, NPM supports polling via WMI, SNMP, and agents. However, interface polling via WMI and Agent is not supported unless you have a SAM license.  You must use SNMP as a polling method to obtain interface data in an NPM-only installation. For details, see Polling methods used by Orion .

Cell	Detail
31: Agent	"Partial" assumes the Orion Server or Additional Polling Engine (APE) the node is associated with has routable connectivity to the agent-managed node and that the Windows node is running an SSH Daemon, such as freeSSHd (© 2008-2015 Kresimir Petric, available at http://www.freesshd.com, obtained on December 4, 2018). The Web Based SSH Client communicates over TCP Port 22 from the Orion Server or APE to the selected node and does not utilize the agent communications channel. The Windows Operating System also does not include a native out-of-the-box SSH Server. Windows however, does provide an unencrypted Telnet service  for similar functionality. Unfortunately, Orion's Web Based SSH client does not support Telnet at this time.
31: WMI, SNMP	"Partial" assumes the Windows node is running an SSH Daemon, such as freeSSHd (© 2008-2015 Kresimir Petric, available at http://www.freesshd.com, obtained on December 4, 2018). The Windows Operating System does not include a native out-of-the-box SSH Server. Windows however, does provide an unencrypted Telnet service for similar functionality. Unfortunately, Orion's Web Based SSH client does not support Telnet at this time.
102: WMI, SNMP	Windows Script Monitors run against SNMP or WMI managed nodes and execute locally on the Orion Server or Additional Poller through which the node is managed. These Windows Scripts do not execute on the managed node itself. To execute Windows Scripts on the node being managed, users must install the Orion Agent or rewrite their script in PowerShell utilizing WinRM.
