(Input Node names or use the list function to select Nodes) | | Run On | The number of Nodes that will run the test at each scheduled interval. - **All Nodes** - every selected Node executes the Test every time. - **Subset of Nodes** - the specified quantity of Nodes (randomly selected) executes the Test each time. | | Frequency | The time interval between Test runs. | | Node Distribution | - **Random** - Test is run at a different time by each Node during the scheduled interval. - **Concurrent** - Test is run at approximately the same time on all Nodes during each scheduled interval. | | Run Schedule | Times during which Tests ***will*** run. (Must be pre-configured in the Settings Module. You can Save your progress and return to this configuration if you need to create a Schedule.) | | Maintenance Schedule | Times during which Tests will ***not*** run. (Must be pre-configured in the Settings Module. You can Save your progress and return to this configuration if you need to create a Schedule.) |
