Hippo4j 动态线程池监控优化改造

   
    0 0 zzzzchen

一、本次优化点

  1. 「线程池监控」查询范围由原先的 30 分钟改为 60 分钟且可配置化；
  2. 「线程池监控」增加时间选择器，可选范围 10 天；
  3. 「线程池监控」数据库数据持久化 10 天且可配置；

二、优化步骤

前端部分：增加时间选择器组件、设置默认时间、中英文转译、传递至后端

  1. 修改页面路径：/hippo4j-ui/src/views/hippo4j/monitor/index.vue，在 class 为「filter-container」的大块后面接着写

    1    <div>
2      <el-date-picker v-model="listQuery.entTime" type="datetime" placeholder="请选择截止时间" :picker-options="pickerOptions">
3      </el-date-picker>
4    </div>

  2. 选择地址及端口的选择器代码修改

    1      <el-select v-model="listQuery.identify" :placeholder="$t('threadPoolMonitor.ipPortRequired')" style="width: 220px"
2        filterable class="filter-item" @change="identifyChange">
3        <el-option v-for="item in identifyOptions" :key="item.key" :label="item.display_name" :value="item.key" />
4      </el-select>

  3. 「data」块更改

     1  data() {
 2    return {
 3      pickerOptions: {
 4        disabledDate(time) {
 5          let curDateMillisecond = (new Date()).getTime();
 6          let tenDaysMillisecond = 10 * 24 * 3600 * 1000;
 7          let tenDaysTime = curDateMillisecond - tenDaysMillisecond;
 8          return time.getTime() > Date.now() || time.getTime() < tenDaysTime;;
 9        }
10      },
11      listQuery: {
12        endTime: null
13      },
14      endTime: null
15    };
16  }

  4. 「methods」方法更改

     1    identifyChange(identify) {
 2      if (identify) {
 3        this.endTime = new Date();
 4      }
 5    },
 6    fetchData() {
 7      if (!this.listQuery.tenantId) {
 8        this.$message.warning(this.$t('message.emptyWarning', { name: this.$t('tenantManage.tenant') }));
 9        return;
10      }
11      if (!this.listQuery.itemId) {
12        this.$message.warning(this.$t('message.emptyWarning', { name: this.$t('projectManage.item') }));
13        return;
14      }
15      if (!this.listQuery.tpId) {
16        this.$message.warning(this.$t('message.emptyWarning', { name: this.$t('threadPool.threadPool') }));
17        return;
18      }
19      if (!this.listQuery.identify) {
20        this.$message.warning(this.$t('message.emptyWarning', { name: this.$t('threadPoolMonitor.ipPort') }));
21        return;
22      }
23      if (this.endTime) {
24        let time = this.endTime;
25        time.setHours(time.getHours() + 8);
26        this.listQuery.endTime = time.toISOString();
27        time.setHours(time.getHours() - 8);
28      }
29      this.listQuery.instanceId = this.listQuery.identify;
30      threadPoolApi.info(this.listQuery).then((res) => {
31        this.temp = res;
32      });
33
34      // monitorApi.lastTaskCountFun(this.listQuery).then((res) => {
35      //   this.rejectCount = res.rejectCount;
36      //   this.lastTaskCount = res.completedTaskCount;
37      // });
38
39      this.initChart();
40    },
41    refreshData() {
42      this.listQuery.tenantId = null;
43      this.listQuery.itemId = null;
44      this.listQuery.tpId = null;
45      this.listQuery.identify = null;
46      this.itemOptions = [];
47      this.threadPoolOptions = [];
48      this.identifyOptions = [];
49      this.listQuery.endTime = null;
50      this.endTime = null;
51    }

  5. 中英文转译，js 路径 /hippo4j-ui/src/locale/lang/zh.js、/hippo4j-ui/src/locale/lang/en.js，分别在 js 页面下找到如下代码块，增加 chooseDeadline 以及对应翻译

     1  //线程池监控
 2  threadPoolMonitor: {
 3    ipPort: 'IP : Port',
 4    ipPortRequired: 'IP : Port（必填）',
 5    noResultsYet: '暂无结果',
 6    chooseDeadline: '请选择截止时间',
 7  },
 8
 9  //线程池监控
10  threadPoolMonitor: {
11    ipPort: 'IP : Port',
12    ipPortRequired: 'IP : Port(Required)',
13    noResultsYet: 'No results yet',
14    chooseDeadline: 'Choose deadline',
15  },

  6. 编译前端项目，执行「package.json」中 scritps 的第二个命令 vue-cli-service build，会生成或重新替换 dist 目录下的文件，将该目录下的所有文件替换 /hippo4j//hippo4j-server/hippo4j-console/src/main/resources/static 该目录下的静态文件，前端即完成；也可单独将前端代码拉出来部署，后端不依赖静态文件，需要改动前端访问后端接口的 ip+port，在 vue.config.js 中 查找 http://127.0.0.1:6691/hippo4j/v1/cs 后替换即可；

后端部分：接口动态查询，数据持久化配置、查询范围配置

  1. 我这边是将原本的内置配置文件，改为了读取 nacos 中的配置文件，有个一层注册中心的概念，大家可参考下；

  2. 在 hippo4j-config 的 pom.xml 中引入如下依赖

    1        <dependency>
2            <groupId>org.springframework.cloud</groupId>
3            <artifactId>spring-cloud-starter-bootstrap</artifactId>
4            <version>3.0.2</version>
5        </dependency>

  3. 修改 ServerBootstrapProperties 类

  5. 修改 HisRunDataServiceImpl 类下的 query、queryInfoThreadPoolMonitor、queryThreadPoolLastTaskCount 方法

     1    @Override
 2    public List<MonitorRespDTO> query(MonitorQueryReqDTO reqDTO) {
 3        LocalDateTime currentDate = LocalDateTime.now();
 4        LocalDateTime dateTime = currentDate.plusMinutes(-properties.getQueryHistoryDataPeriod());
 5        long startTime = DateUtil.getTime(dateTime);
 6        List<HisRunDataInfo> hisRunDataInfos = this.lambdaQuery()
 7                .eq(HisRunDataInfo::getTenantId, reqDTO.getTenantId())
 8                .eq(HisRunDataInfo::getItemId, reqDTO.getItemId())
 9                .eq(HisRunDataInfo::getTpId, reqDTO.getTpId())
10                .eq(HisRunDataInfo::getInstanceId, reqDTO.getInstanceId())
11                .between(HisRunDataInfo::getTimestamp, startTime, DateUtil.getTime(currentDate))
12                .orderByAsc(HisRunDataInfo::getTimestamp)
13                .list();
14        return BeanUtil.convert(hisRunDataInfos, MonitorRespDTO.class);
15    }
16
17    @Override
18    public MonitorActiveRespDTO queryInfoThreadPoolMonitor(MonitorQueryReqDTO reqDTO) {
19        LocalDateTime currentDate;
20        if (Objects.isNull(reqDTO.getEndTime())) {
21            currentDate = LocalDateTime.now();
22        } else {
23            currentDate = reqDTO.getEndTime();
24        }
25        LocalDateTime dateTime = currentDate.plusMinutes(-properties.getQueryHistoryDataPeriod());
26        long startTime = DateUtil.getTime(dateTime);
27        List<HisRunDataInfo> hisRunDataInfos = this.lambdaQuery()
28                .eq(HisRunDataInfo::getTenantId, reqDTO.getTenantId())
29                .eq(HisRunDataInfo::getItemId, reqDTO.getItemId())

31                .eq(HisRunDataInfo::getInstanceId, reqDTO.getInstanceId())
32                .between(HisRunDataInfo::getTimestamp, startTime, DateUtil.getTime(currentDate))
33                .orderByAsc(HisRunDataInfo::getTimestamp)
34                .list();
35        List<String> times = new ArrayList<>();
36        List<Long> poolSizeList = new ArrayList<>();
37        List<Long> activeSizeList = new ArrayList<>();

46        for (HisRunDataInfo each : hisRunDataInfos) {
47            String time = DateUtil.format(new Date(each.getTimestamp()), NORM_TIME_PATTERN);
48            times.add(time);
49            poolSizeList.add(each.getPoolSize());
50            activeSizeList.add(each.getActiveSize());
51            queueSizeList.add(each.getQueueSize());
52            rejectCountList.add(each.getRejectCount());
53            queueRemainingCapacityList.add(each.getQueueRemainingCapacity());
54            currentLoadList.add(each.getCurrentLoad());
55            queueCapacityList.add(each.getQueueCapacity());
56            if (firstFlag.get()) {
57                completedTaskCountList.add(0L);
58                firstFlag.set(Boolean.FALSE);
59                countTemp = each.getCompletedTaskCount();
60                continue;
61            }
62            long completedTaskCount = each.getCompletedTaskCount();
63            long countTask = completedTaskCount - countTemp;
64            completedTaskCountList.add(countTask);
65            countTemp = each.getCompletedTaskCount();
66        }
67        return new MonitorActiveRespDTO(times, poolSizeList, activeSizeList, queueSizeList, completedTaskCountList, rejectCountList, queueRemainingCapacityList, currentLoadList, queueCapacityList);
68    }
69
70    @Override
71    public MonitorRespDTO queryThreadPoolLastTaskCount(MonitorQueryReqDTO reqDTO) {
72        LocalDateTime currentDate = LocalDateTime.now();
73        LocalDateTime dateTime = currentDate.plusMinutes(-properties.getQueryHistoryDataPeriod());
74        long startTime = DateUtil.getTime(dateTime);
75        HisRunDataInfo hisRunDataInfo = this.lambdaQuery()
76                .eq(HisRunDataInfo::getTenantId, reqDTO.getTenantId())
77                .eq(HisRunDataInfo::getItemId, reqDTO.getItemId())
78                .eq(HisRunDataInfo::getTpId, reqDTO.getTpId())
79                .eq(HisRunDataInfo::getInstanceId, reqDTO.getInstanceId())
80                .orderByDesc(HisRunDataInfo::getTimestamp)
81                .between(HisRunDataInfo::getTimestamp, startTime, DateUtil.getTime(currentDate))
82                .last("LIMIT 1")
83                .one();
84        return BeanUtil.convert(hisRunDataInfo, MonitorRespDTO.class);
85    }

  6. 在 nacos 中可以自定义查询时间以及数据持久化时间配置，由于加了 @RefreshScope 注解，修改后会立即生效

    1# 是否开启线程池历史数据清洗 false 不开启
2hippo4j:
3  core:
4    clean-history-data-enable: true
5    clean-history-data-period: 14400
6    query-history-data-period: 60

三、注意事项

  1. 客户端在每次启动时，都会根据一些信息动态的生成实例标识，这也是查询线程池监控数据的查询参数，这就导致了，本次启动后会查询不到之前的线程池监控数据；
