VMware NSX ZenPack

VMware NSX-T monitoring.


Version 2.0.0- Download

Compatible with Zenoss Resource Manager 6.5.0, 6.6.0, and Zenoss Cloud

Version 1.2.1- Download
Released on 2017/02/01

This is the last version that supports VMware NSX-V


This ZenPack provides support for monitoring VMware NSX-T. Modeling and monitoring of devices placed in the /VMware/NSX device class is performed using the NSX-T API by executing queries and parsing the output.


The NSX ZenPack provides:

  • Initial discovery and continual synchronization of relevant components.
  • Performance monitoring.
  • System event management.
  • Service impact and root cause analysis (Requires Zenoss Service Dynamics).
  • Collection of detailed configuration data, including NAT Rules, Routing Protocols, Load Balancer Configs, and Firewall Configs.
  • Service impact and root cause analysis (Requires Zenoss Service Dynamics).


The following entities will be automatically discovered. The attributes and collections will be updated on Zenoss's normal remodeling interval which defaults to every 12 hours.

The installation of this ZenPack will create the device class /VMware/NSX. This new device class will provide five new zProperties zNSXUsername, zNSXPassword, zNSXPort, zNSXSSL, and zNSXConcurrentHTTP

Add a NSX-T Device

The following procedure assumes that credentials have been set.

  • Select Infrastructure from the navigation bar.
  • Select Add a Single Device from the Add Device list of options. The Add a Single Device dialog appears.
  • Enter the following information in the dialog:

    Name or IPNSX host to model.
    Device Class/VMware/NSX
    Model DeviceSelect this option unless adding a device with a user name and password
    different than found in the device class. If you do not select this option,
    then you must add the credentials (see) and then manually model the device.
    zNSXUsernameNSX user with privileges to gather performance information
    zNSXPasswordPassword for the NSX User
    zNSXSSLEnable SSL for communication with NSX
  • Click Add.

System Event Monitoring

Monitoring plugin collects System Events from NSX-T Manager and shows them as Zenoss Events with the same time and severity.

Standard Zenoss Event Fields
  • device
  • component
  • summary
  • severity
  • eventClassKey (for mapping specific event types)
  • eventKey (for de-duplication and auto-clear fingerprinting)

Once the event is sent, it will not be sent again. If the user clears the event, it will not reappear again. There’s no automatic mechanism to clear system events, as they can not be cleared from NSX manager and do not have expire date, therefore the user is to close new events manually from Zenoss UI.

Installing this ZenPack will add the following items to your Zenoss system.

Note: disk_space_total and disk_space_used values may be different from the values in NSX UI. Zenoss takes these values from the NSX API, but NSX UI doesn't. NSX UI iterates though file_systems field and sums the total_space of each file system with some inaccuracy (NSX UI uses 1000 as base, not 1024, for converting kbytes to other units)
