一、背景
最近在做性能壓測方面的工作，用的壓測工具是Jmeter。Jmeter中有一個插件叫
jp@gc Throughput Shaping Timer。翻譯過來就是吞吐量整形定時器。如下圖：
Throughput Shaping Timer
它可以設計梯度的并發(fā)請求，并且每種并發(fā)請求量(RPS)都可以設定執(zhí)行的時間。
壓測完成后，可以通過Jmeter的聚合報告查看壓測結果。如下圖：
聚合報告
但是這里存在一個問題。就是如果我想要知道每一種RPS下的平均響應時間，TP90,TP95,TP99,錯誤率，吞吐量等信息，就沒有辦法從聚合報告中獲取?？赡躂mter提供了類似功能的插件，但是我沒有找到。
我們都知道Jmeter的壓測結果是jtl文件，不知道大家有沒有看過jtl文件里面的內容。就是就是一行行的請求記錄。如下圖：

上面是我截取的一部分jtl文件的內容。下面做一下解釋：
1542884219715,4,http請求,200,OK,Stepping Thread Group 1-1,text,true,318,1,1,3
timeStamp,elapsed,label,responseCode,responseMessage,threadName,dataType,success,failureMessage,bytes,Latency
請求發(fā)出的絕對時間，響應時間，請求的標簽，返回碼，返回消息，請求所屬的線程，數(shù)據(jù)類型，是否成功，失敗信息，字節(jié)，響應時間
倒數(shù)第二位和第三位沒搞懂是什么意思，不過不影響。
二、實現(xiàn)
有了上面的jtl知識后，相信有點程序基礎的同學都可以設計程序來實現(xiàn)獲得每種RPS的壓測結果信息。
貼一下我自己的代碼
首先是JtlResolver類
package com.lin.performance.testing;
import com.alibaba.fastjson.JSONObject;

public class JtlResolver {
public String resloveJtl(File file,List<Integer> durationList) throws IOException {
BufferedReader br = new BufferedReader(new InputStreamReader(new FileInputStream(file)));
String oneLine = null;
//所有的行
List<String> totalLines = new ArrayList<String>();
List<Long> timestampList = new ArrayList<Long>();
while ((oneLine = br.readLine()) != null){
totalLines.add(oneLine);
String[] split = oneLine.split(",");
String timestampStr = split[0];
Long timestamp = Long.valueOf(timestampStr);
timestampList.add(timestamp);
}
System.out.println("totalLines:"+totalLines.size());
System.out.println("第一行:"+totalLines.get(0));
System.out.println("最后一行："+totalLines.get(totalLines.size()-1));
System.out.println();
//壓測開始時間
String allStartTimestampStr = totalLines.get(0).split(",")[0];
Long allStartTime = Long.valueOf(allStartTimestampStr);
//壓測結束時間
String allEndTimestampStr = totalLines.get(totalLines.size() - 1).split(",")[0];
Long allEndTime = Long.valueOf(allEndTimestampStr);
Long startTime = allStartTime;
Long endTime = allEndTime;
Integer startIndex = 0;
for (int i=0;i<durationList.size();i++){
Integer duration = durationList.get(i);
if (durationList.size() != 1){
endTime = startTime + duration*1000;
}
if (i == (durationList.size() - 1)){

}
//計算開始和結束
Integer endIndex = getEndIndex(endTime, timestampList);
getOneRpsResult(startIndex,endIndex,startTime,endTime,timestampList,totalLines);
startTime = endTime;
startIndex = endIndex;
}
return null;
}
private void getOneRpsResult(Integer startIndex,Integer endIndex,Long startTime,Long endTime,List<Long> timestampList,List<String> totalLines){
int index=0;
//總的響應時間
int sumElapsed=0;
Integer failSize = 0;
Integer totalBytes = 0;
List<Integer> elapsedList = new ArrayList<Integer>();
for (Integer i = startIndex;i<=endIndex;i++){
try {
String row = totalLines.get(i);
String[] split = row.split(",");
//響應時間
String elapsed = split[1];
sumElapsed += Integer.valueOf(elapsed);
elapsedList.add(Integer.valueOf(elapsed));
//成功與否
String success = split[7];
if (!"true".equals(success)){
failSize++;
}
//字節(jié)
String bytes = split[8];
totalBytes += Integer.valueOf(bytes);
index++;
}catch (Exception e){
System.out.println("exception i:"+i);
}
}
Collections.sort(elapsedList, new Comparator<Integer>() {
public int compare(Integer o1, Integer o2) {
return o1-o2;
}
});
Integer tp90 = elapsedList.size()*9/10;
Integer tp95 = elapsedList.size()*95/100;
Integer tp99 = elapsedList.size()*99/100;
Long l = timestampList.get(index-1) - timestampList.get(0);
SceneResult sceneResult = new SceneResult();
sceneResult.setStartTimeStr(DateFormatUtils.format(startTime,"yyyy-MM-dd HH:mm:ss"));
sceneResult.setEndTimeStr(DateFormatUtils.format(endTime,"yyyy-MM-dd HH:mm:ss"));
sceneResult.setSamples(index+"");
sceneResult.setAverage(sumElapsed/index+"");
sceneResult.setTp90(elapsedList.get(tp90)+"");
sceneResult.setTp95(elapsedList.get(tp95)+"");
sceneResult.setTp99(elapsedList.get(tp99)+"");
sceneResult.setMin(elapsedList.get(0)+"");
sceneResult.setMax(elapsedList.get(index-1)+"");
sceneResult.setMedian(elapsedList.get(index/2)+"");
sceneResult.setErrors(String.format("%.2f",failSize*100.0/index)+"%");
sceneResult.setThroughput(String.format("%.2f",index*1.0/(l*1.0/1000)));
sceneResult.setKbPerSec(String.format("%.2f",totalBytes*1.0/1024/(l*1.0/1000)));
System.out.println(JSONObject.toJSONString(sceneResult));
System.out.println();
}
private Integer getStartIndex(Long startTime,List<Long> timestampList){
int index = 0;
for (int i=0;i<timestampList.size()-1;i++){
if (startTime.longValue() >= timestampList.get(i).longValue() && startTime.longValue() <= timestampList.get(i+1).longValue()){
return index;
}
index++;
}
return index;
}
private Integer getEndIndex(Long endTime,List<Long> timestampList){
for (int i=timestampList.size()-1;i>=0;i--){
if (endTime.longValue() >= timestampList.get(i).longValue()){
return i;
}
}
return 0;
}
public static void main(String[] args) throws IOException {
List<Integer> durationList = new ArrayList<Integer>();
durationList.add(10);
durationList.add(10);
durationList.add(10);
durationList.add(10);
durationList.add(10);
durationList.add(10);
File file = new File("/Users/xmly/Documents/stresstest/jtl/welfare-banners-1-5.jtl");
new JtlResolver().resloveJtl(file,durationList);
}
}
然后是SceneResult類
package com.lin.performance.testing.po;
public class SceneResult {
/**開始壓測時間*/
private String startTimeStr;
/**結束壓測時間*/
private String endTimeStr;
/**壓測請求數(shù)*/
private String samples;
/**平均響應時間*/
private String average;
/**90% Line*/
private String tp90;
/**95% Line*/
private String tp95;
/**99% Line*/
private String tp99;
/**最小請求時間*/
private String min;
/**最大請求時間*/
private String max;
/**錯誤率*/
private String errors;
/** throughput */
private String throughput;
/**吞吐量 KB/sec*/
private String kbPerSec;
/**中間時間*/
private String median;
public String getMedian() {
return median;
}
public void setMedian(String median) {
this.median = median;
}
public String getSamples() {
return samples;
}
public void setSamples(String samples) {
this.samples = samples;
}
public String getAverage() {
return average;
}
public void setAverage(String average) {
this.average = average;
}
public String getTp90() {
return tp90;
}
public void setTp90(String tp90) {
this.tp90 = tp90;
}
public String getTp95() {
return tp95;
}
public void setTp95(String tp95) {
this.tp95 = tp95;
}
public String getTp99() {
return tp99;
}
public void setTp99(String tp99) {
this.tp99 = tp99;
}
public String getMin() {
return min;
}
public void setMin(String min) {
this.min = min;
}
public String getMax() {
return max;
}
public void setMax(String max) {
this.max = max;
}
public String getErrors() {
return errors;
}
public void setErrors(String errors) {
this.errors = errors;
}
public String getThroughput() {
return throughput;
}
public void setThroughput(String throughput) {
this.throughput = throughput;
}
public String getKbPerSec() {
return kbPerSec;
}
public void setKbPerSec(String kbPerSec) {
this.kbPerSec = kbPerSec;
}
public String getStartTimeStr() {
return startTimeStr;
}
public void setStartTimeStr(String startTimeStr) {
this.startTimeStr = startTimeStr;
}
public String getEndTimeStr() {
return endTimeStr;
}
public void setEndTimeStr(String endTimeStr) {
this.endTimeStr = endTimeStr;
}
}
運行JtlResolver類中的main方法，獲得的結果如下：
