TaskStats

• java.lang.Object

Fields Summary
private org.apache.lucene.benchmark.byTask.tasks.PerfTask	task task for which data was collected
private int	round round in which task run started
private long	start task start time
private long	elapsed task elapsed time. elapsed >= 0 indicates run completion!
private long	maxTotMem max tot mem during task
private long	maxUsedMem max used mem during task
private int	taskRunNum serial run number of this task run in the perf run
private int	numParallelTasks number of other tasks that started to run while this task was still running
private int	count number of work items done by this task. For indexing that can be number of docs added. For warming that can be number of scanned items, etc. For repeating tasks, this is a sum over repetitions.
private int	numRuns Number of similar tasks aggregated into this record. Used when summing up on few runs/instances of similar tasks.

Constructors Summary
TaskStats(org.apache.lucene.benchmark.byTask.tasks.PerfTask task, int taskRunNum, int round) Create a run data for a task that is starting now. To be called from Points. this.task = task; this.taskRunNum = taskRunNum; this.round = round; maxTotMem = Runtime.getRuntime().totalMemory(); maxUsedMem = maxTotMem - Runtime.getRuntime().freeMemory(); start = System.currentTimeMillis();

Methods Summary
public void	add(org.apache.lucene.benchmark.byTask.stats.TaskStats stat2) Add data from another stat, for aggregation param stat2 the added stat data. numRuns += stat2.getNumRuns(); elapsed += stat2.getElapsed(); maxTotMem += stat2.getMaxTotMem(); maxUsedMem += stat2.getMaxUsedMem(); count += stat2.getCount(); if (round != stat2.round) { round = -1; // no meaning if agregating tasks of different ruond. }
public java.lang.Object	clone() return super.clone();
public int	getCount() return Returns the count. return count;
public long	getElapsed() return elapsed time. return elapsed;
public long	getMaxTotMem() return Returns the maxTotMem. return maxTotMem;
public long	getMaxUsedMem() return Returns the maxUsedMem. return maxUsedMem;
public int	getNumParallelTasks() return Returns the numParallelTasks. return numParallelTasks;
public int	getNumRuns() return Returns the numRuns. return numRuns;
public int	getRound() return the round number. return round;
public org.apache.lucene.benchmark.byTask.tasks.PerfTask	getTask() return Returns the task. return task;
public int	getTaskRunNum() return the taskRunNum. return taskRunNum;
void	markEnd(int numParallelTasks, int count) mark the end of a task elapsed = System.currentTimeMillis() - start; long totMem = Runtime.getRuntime().totalMemory(); if (totMem > maxTotMem) { maxTotMem = totMem; } long usedMem = totMem - Runtime.getRuntime().freeMemory(); if (usedMem > maxUsedMem) { maxUsedMem = usedMem; } this.numParallelTasks = numParallelTasks; this.count = count;
public java.lang.String	toString() StringBuffer res = new StringBuffer(task.getName()); res.append(" "); res.append(count); res.append(" "); res.append(elapsed); return res.toString();
