Supported versions

The VMWare monitor allows monitoring any version of any VMWare system: vCenter, ESX Server or VMWare Server.

NeoLoad accesses these systems Web services using SOAP requests. The VMWare monitoring API is available on all versions of all the VMWare systems as a whole.

Connection settings

Defining a VMWare monitor requires an HTTP server (defined in the Design > Virtual Users > Servers), a path to the VMWare Web services (/sdk by default), and a user name and password for authentication (those used to connect to the VMWare management interface).

The server to be used can be created in the Servers section of the Virtual Users, or a server created during a recording can be used.


The infrastructure for monitoring VMWare servers enables the retrieval of statistics from the various entities (hosts or virtual machines) at intervals defined on the server. By default, the shortest monitoring interval is 5 minutes. This interval can only be changed on vCenter systems.

NeoLoad automatically detects the shortest monitoring interval and sets the same monitoring interval for the created Monitor to avoid multiple retrieval of the same counter value.

Create an VMWare monitor

NeoLoad makes it possible to create a new monitor either using the monitored machine creation wizard, as described in Create and configure a monitored machine, or from an existing monitored machine, as described in Create and configure a monitor.

NeoLoad shows a list of the VMWare systems declared for the server. This list will only show multiple systems in the case of a Center server. In all other cases, only the system to be monitored will be listed.

NeoLoad shows a list of VMWare virtual machines started on the previously-selected servers.

Available counters


The following is a list of available counters. Not all are present on all VMWare systems (vCenter, ESX Server, VMWare Server) or VMWare virtual machines.
