MediationZone constantly collects information from the different sub-systems and hosts within the system. Among other things, this information is used for load balancing. Using System Statistics, you can view, export, and import statistical information.
...
The system collects statistics from the different machines hosting a Platform or Execution Context, e.g. the load of the CPU or the number of context switches. This is called host statistics.
MediationZone uses the
std UNIX command to collect the information. This binary must be installed to have statistics collected and to perform load-balancing work for workflows. The following list holds all values collected from each host. On newer operating systems, some of these may not be available for collection due to changes in the kernel of the operation system.

In the Filter dialog, search criteria may be defined in order to single out the Statistics of interest.
