Node-based licensing in SAM

A node-based SAM license governs how many managed nodes can be monitored within your environment, while allowing for an unlimited number of component monitors per node. This scheme provides an alternative to component-based licensing, which controls how many component monitors can be assigned.

The term "managed node" can be interpreted differently, depending on if you're using other Orion Platform modules with SAM:

  • In a SAM-only environment, a managed node is any entity from which SAM extracts data directly via supported polling methods (for example, WMI), Orion agents, or API pollers. Nodes monitored by Asset Inventory and/or Hardware Health are also considered managed nodes in a SAM-only environment.
  • If your environment includes SAM and other Orion Platform modules, the SAM node count has the potential to be additive to other modules that use node licensing, such as SolarWinds NPM. In a multi-module scenario, only nodes being monitored by SAM application monitors or API pollers are classified as managed nodes for SAM. Nodes monitored by Asset Inventory and/or Hardware Health do not impact licensing.

In either case, a managed node can represent a traditional server, VM, hypervisor, or Nutanix cluster, as well as an external node, external API, or service.

A VM being monitored directly counts as a single managed node. However, individual VMs on a hypervisor do not count as multiple managed nodes when performance metrics are gathered from the parent hypervisor. In that case, the parent hypervisor is the managed node.

Available license tiers

Count the number of managed nodes in your environment to determine the most suitable license tier.

Component-based licensing in SAM

A component-based SAM license is similar to an NPM license, replacing interfaces for components, based on nodes, volumes, or assigned component monitors — whichever is highest. For example, with an AL150 license, you can monitor 150 nodes, 150 volumes, and 150 component monitors.

Each component monitor consumes one license. A typical application monitor (also called an application) includes 15 — 25 component monitors, while AppInsight applications consume a flat rate of either 30 or 50 licenses each.

In addition to application monitors, SAM features such as API Pollers also consume licenses. For example, the Windows Scheduled Task Monitor consumes 5 licenses for each monitored Windows server. Asset Inventory data collection does not consume SAM licenses.

You can use as many component monitors as needed, as long as the number of assigned component monitors doesn't exceed the license count. If you exceed a license limit, component monitors beyond the limit are not activated and their statuses change to Not Licensed. Either disable assigned component monitors to reduce license consumption, or upgrade your license. This also applies to API Poller metrics.

The following table lists available component-based license levels:

SAM license tiers
(component-based licensing)
Number of
monitored components
AL150 150
AL300 300
AL700 700
AL1100 1100
AL1500 1500
AL2500 2500
ALX Unlimited number of items to monitor standard polling throughput.

To verify the number of consumed and available component monitors, navigate to the SAM License Summary:

  1. Click Settings > All Settings.
  2. Under Product Specific Settings, click SAM Settings.
  3. Click SAM License Summary.

Note the following details about component-based licensing:

Verify the number of component monitors consumed per template

As described here, each SAM application monitor template includes one or more component monitors designed to monitor the availability or a statistic of a specific element, such as a server, application, process, service, port, or URL. You can assign templates to nodes to create application monitors (also called "applications") that are specific to each node.

For most application monitors, you can add, disable, or delete component monitors, as necessary. Each active component monitor in an application monitor counts against your license. However, note that AppInsight application behave differently, consuming licenses at a flat rate.

​Example: The environment depicted on the Manage Assign Application Monitors page shown here includes:

  • The AppInsight for IIS template uses a flat rate that consumes 30 licenses per assigned application monitor, even though 152 component monitors actively poll on behalf of each application monitor.
  • The Server Clock Drift template consumes 2 licenses for 1 assigned application monitor.
  • The Web Link template only consumes 1 license for 1 assigned application monitor.

If you have an AL150 license and use all component monitors from each template, you consume 33 (30+2+1) component monitor licenses out of the available 150.

To view the number of licensed component monitors consumed per template in SAM, navigate to the Manage Application Monitor Templates page.

  1. Click Settings > All Settings > SAM Settings.
  2. Under Product Specific Settings, click SAM Settings
  3. Under Application Monitor Templates, click Manage Templates.
  4. Review the Licensed Components column for each template.

Verify the number of component monitors that are currently active

To determine how many component licenses are currently active, click Settings > All Settings > SAM Settings > Manage Application Monitors to open the Manage Assign Application Monitors page.


You can also create a report about licensed component monitors.

To check the number of component monitors assigned to each polling engine, see How to display all components polled for each polling engine. See also Check the number of available component monitors in my SAM license.

AppInsight applications consume licenses at flat rates

Note that AppInsight applications consume a fixed number of component monitor licenses; you cannot add component monitors and some key component monitors cannot be disabled. Due to the complexity of AppInsight templates, they collect data in a different way than most templates and cannot be partially unlicensed.

Although you can disable some component monitors within AppInsight applications, that won't reclaim component monitor licenses because AppInsight applications typically monitor far more components than cited in their flat rates, as listed here:

  • AppInsight for Active Directory: 50 component monitors per monitored domain controller
  • AppInsight for Exchange: 50 component monitors per monitored mailbox role server
  • AppInsight for IIS: 30 component monitors per monitored IIS server
  • AppInsight for SQL: 50 component monitors per database instance

If you encounter heavy polling loads and need to determine how many component monitors collect data for individual AppInsight applications assigned to nodes, see Review polling engine loads. An Active Components column was added to the Manage Assigned Application Monitors page in SAM 2020.2.6.

Determine your SAM license type

To check which type of license you have:

  1. Click Settings > All Settings > License Details.
  2. Examine the SAM section of the License Details page:

You can also check your license type in the SolarWinds Customer Portal.

  1. Log into the SolarWinds Customer Portal.
  2. Click Licenses > Manage Licenses.
  3. Scroll down to the Server & Application Monitor row.

If a license starts with SAM (for example, SAM200), SAM uses a node-based license.

If a license starts with AL (AL2500), SAM uses a component-based license.

To switch to node-based licensing, contact SolarWinds Sales. Note that, after updating licensing, it may take one or two polling cycles for polling rate details to refresh in the Orion Web Console.

Manage your SAM license

Like other Orion Platform products, SAM uses the web-based License Manager to license the Orion server, APEs, Additional Web Servers, and High Availability (HA) pools.

To manage SAM and other licenses after you install SAM:

  1. Click Settings > All Settings.
  2. Click License Details in the Details section.

  3. Click License Manager.

You can sort licenses by product name, version, license type, or expiration date. You can also add a license, upgrade a license, and activate licenses on new servers. The License Manager on the Orion server controls all licenses for your SAM environment.

If prompted to activate your SAM license, use your individual Customer ID (also called a "SWID") to log into the Customer Portal. If you do not know your ID, enter a Support ticket.

Add polling engines to scale your environment

In the Orion Platform, an Additional Polling Engine (APE) is a type of scalability engine that you can add to any SAM environment, regardless of license type, to:

  • Distribute polling away from the Main Polling Engine,
  • Boost Orion Web Console performance, and
  • Help ensure high availability (HA).

To maximize polling capacity, see SAM polling recommendations.

With a node-based SAM license, you can add APEs at no extra cost. Note the following details about "included" APEs:

  • They collect SAM and basic Orion Platform data only. For example, APEs can return application metrics, plus basic node status and volume metrics, but not NPM interface data.
  • With a unified SAM license key in SAM 2020.2 and later, polling engine licenses are stacked automatically, with built-in scalability. You can monitor up to 40,000 component monitors per server at standard polling frequencies. If you exceed that limit, polling intervals are automatically extended.

  • APE port requirements match Main Polling Engine port requirements.

To learn more about APEs, see:

How your SAM license relates to other Orion Platform module licenses

If your SAM environment includes other Orion Platform modules, licenses may interact with your SAM license in different ways, depending on the module.

SolarWinds Network Performance Monitor (NPM)

A node-based SAM license governs how many managed nodes can be monitored in your SAM environment, while allowing for an unlimited number of component monitors per node.

A component-based SAM license is similar to an NPM license, replacing interfaces for components. That is, SAM is licensed based on nodes, volumes, or component monitors — whichever is highest. For example, you can monitor 150 nodes, 150 volumes, and 150 component monitors simultaneously with an AL150 license.

If your deployment includes both SAM and NPM, the combined licenses can extend the total number of nodes being monitored. If you have an NPM SL500 (500 nodes and 500 volumes) license and a SAM AL150 component-based license, you can monitor:

  • 650 nodes, including:
    • 500 nodes, monitored by NPM, and
    • 150 nodes, monitored by SAM.
  • 650 volumes. The number of volumes matches the node count in the license.
  • 500 interfaces monitored with SNMP.
  • 150 component monitors.
  • An unlimited number of interfaces polled using WMI.

SolarWinds Network Automation Manager (NAM)

NAM is a bundle of the following modules: IP Address Manager (IPAM), Network Configuration Manager (NCM), NPM, NetFlow Traffic Analyzer (NTA), User Device Tracker (UDT), and VoIP and Network Quality Manager (VNQM), plus SolarWinds High Availability (HA). Because NAM includes NPM, the combined NPM and SAM licenses extend the total number of nodes being monitored, as described earlier.

If NAM and SAM are both deployed, you can use NAM APEs and then add APEs at no extra cost with a node-based SAM license. However, note that the "included" SAM APEs collect SAM and basic Orion Platform data only. For example, a SAM APE can return application metrics, basic node status, and volume metrics, but not NPM interface data.

SolarWinds Log Analyzer (LA)

If you use LA and SAM, you'll only receive LA-related messages for nodes being monitored by LA. For example, if you have NPM SL100, SAM AL100, and LA100 licenses, you can monitor up to 300 nodes but you'll only receive LA-related messages from the 100 nodes specifically monitored by LA.

To learn how LA interacts with Orion Log Viewer (OLV) and SAM, see this Success Center article.

SolarWinds Server Configuration Monitor (SCM)

SAM and SCM both support the Asset Inventory feature. Although that feature does not consume extra licenses on its own, a node must be monitored if you want to track Asset Inventory, so at least one license is consumed by the node.
