* timestamp - the unix time (in microseconds) when this line is written to the log file.
* node_id - the id of this node (task).
* new_state - a integer represents the new state this node (whose id is in the node_id column) has just entered. The value of the integer ranges from 0 to 4 and the states they are representing are:
* 0. waiting
* 1. running
* 2. complete
* 3. failed
* 4. aborted
* job_id - the job id of this node in the underline execution system (local or batch system). If the makeflow is executed locally, the job id would be the process id of the process that executes this node. If the underline execution system is a batch system, such as Condor or SGE, the job id would be the job id assigned by the batch system when the task was sent to the batch system for execution.
* nodes_waiting - the number of nodes are waiting to be executed.
* nodes_running - the number of nodes are being executed.
* nodes_complete - the number of nodes has been completed.
* nodes_failed - the number of nodes has failed.
* nodes_aborted - the number of nodes has been aborted.
* node_id_counter - total number of nodes in this makeflow.
