VMware NSX-T Monitoring

Last updated on 17 March, 2023

LogicMonitor’s VMware NSX-T monitoring package leverages the VMware NSX-T Data Center API to monitor and alert on metrics for clusters, cluster managers/controllers, edges, firewalls, load balancers, and other virtualized NSX-T networking components.


As of January 2022, LogicMonitor’s VMware NSX-T package is compatible with NSX-T API versions 2.4 – 3.2.

Note: This monitoring package may work with earlier versions of the NSX-T API, but has not yet been tested. Due to changes in the structure of the NSX-T cluster between major versions, users running API versions 2.x might be unable to collect data for some datapoints on some datasources. See VMware NSX-T API documentation.

Setup Requirements

Add resources into monitoring

Add your VMware NSX-T cluster host into monitoring. For more information on adding resources into monitoring, see Adding Devices.

Obtain credentials

LogicMonitor uses basic authentication to query the NSX-T API and must provide the appropriate credentials to access the NSX-T resource’s data. The NSX-T cluster Manager requires port 443/TCP to be open between host and collector for REST API requests. These credentials must belong to a user account that has been assigned the following minimum permissions:

Role Description
Read-only All API calls made in this package are compatible with read-only access.

Refer to VMware NSX-T documentation for additional information on configuring users and roles.

Assign properties to resources

The following custom properties must be set on the VMware NSX-T resource within LogicMonitor. For more information, see Resource and Instance Properties.

Property Value
nsx.api.user REST API username.
nsx.api.pass REST API password.
system.category VMware_NSX-T will be automatically added by the PropertySource addCategory_VMware_NSXT.

Import LogicModules

From the LogicMonitor public repository, import all VMware NSX-T LogicModules, which are listed in the LogicModules in Package section of this support article. If these LogicModules are already present, make sure you have the most recent versions.

Once the LogicModules are imported (assuming all previous setup requirements have been met), data collection will automatically commence.​


When monitoring NSX-T devices, some aggregated statistics are limited by the API for how often they update. For this reason, we do not recommend customizing the data collection interval lower than the default configuration.


If there is an error, the DataSources will print the error messages to the console. You can see these errors in the output (from the Raw Data tab that displays from the Resources page for each DataSource) when manually polling data. When errors occur, the DataSources will still attempt to collect available data.

LogicModules in Package

LogicMonitor’s package for VMware NSX-T consists of the following LogicModules. For full coverage, make sure that all of these LogicModules are imported into your LogicMonitor platform.

When setting static datapoint thresholds on the various metrics tracked by this package’s DataSources, LogicMonitor follows the technology owner’s best practice KPI recommendations. If necessary, we encourage you to adjust these predefined thresholds to meet the unique needs of your environment. For more information on tuning datapoint thresholds, see Tuning Static Thresholds for Datapoints.
