Configuration

hugepages	integer (Number of reserved hugepages) Default: 100 The number of hugepages which will be reservered by the system. See: https://www.kernel.org/doc/Documentation/vm/hugetlbpage.txt A value of zero will disable the use of huge pages.
stats	number (Statistics interval) Default: 1 Specifies the rate at which statistics about the active paths will be periodically printed to the screen. Setting this value to 5, will print 5 lines per second. A line includes information such as: Source and Destination of path Messages received Messages sent Messages dropped
affinity	integer (Task/Process affinity mask) Default: 0 Restricts the exeuction of the daemon to certain CPU cores. This technique, also called 'pinning', improves the determinism of the server by isolating the daemon processes on exclusive cores. A value of 0 will not change the affinity of the process.
priority	integer Default: 0 Adjusts the scheduling priority of the deamon processes. By default, the daemon uses a real-time optimized FIFO scheduling algorithm. A value of 0 will not change the priority of the process.
idle_stop	boolean Default: true
uuid	string <uuid> (Super-node UUID) Default: "randomly generated" Each VILLASnode instance is identified by a globally unique indentifier / UUID. This UUID can be queried by the API. If the setting is not provided, a UUID will be generated by hashing the active VILLASnode configuration. This ensures that restarting the VILLASnode instance with the identical configuration will yield always the same UUID.
seed	integer (Random number generator seed) Default: 0 The seed for the random number generator used by the VILLASnode instance. If the setting is not provided, a random seed of 0 will be used.
