Assumptions used in performance testing

The data is in this topic is based on the following assumption:

  • The PATROL Agent and PATROL for VMware vSphere are installed on Microsoft Windows 2012 R2 64-bit.
  • The PATROL Agent and PATROL for VMware vSphere are installed on Red Hat Enterprise Linux 7.2 x86_64.
  • The PATROL Agent and PATROL for VMware vSphere monitor a large virtual center that comprises 2500 virtual machines.

  • The PATROL Agent is connected to the Integration Service and only data is sent to Infrastructure Management server using the Integration Service.

  • The PATROL Agent is connected to the Integration Service. Both event and data are sent to Infrastructure Management server using the Integration Service.
  • The network bandwidth between the PATROL Agent and the Integration Service is monitored using tools such as NetLimiter and PerfMon when the PATROL Agent is sending only data to the Integration Service.

  • All the readings are taken in a network bandwidth capacity of 1 Gbps.

PATROL Agent tuning parameters

The following parameters have been documented based on testing the default configuration variables for the data flow between the PATROL Agent and the Integration Service:

ParameterSupported range
Default maximum event message to flow to the Integration Service in one cycle = 10050 - 1000
Default maximum data message to flow to the Integration Service in one cycle= 10050 - 1000

The data value transfer rate between the PATROL Agent and the Integration Service is at 100 parameter values per second.
