本篇內(nèi)容介紹了“大數(shù)據(jù)開(kāi)發(fā)中數(shù)據(jù)表監(jiān)控怎么實(shí)現(xiàn)”的有關(guān)知識(shí)，在實(shí)際案例的操作過(guò)程中，不少人都會(huì)遇到這樣的困境，接下來(lái)就讓小編帶領(lǐng)大家學(xué)習(xí)一下如何處理這些情況吧！希望大家仔細(xì)閱讀，能夠?qū)W有所成！

讓客戶滿意是我們工作的目標(biāo)，不斷超越客戶的期望值來(lái)自于我們對(duì)這個(gè)行業(yè)的熱愛(ài)。我們立志把好的技術(shù)通過(guò)有效、簡(jiǎn)單的方式提供給客戶，將通過(guò)不懈努力成為客戶在信息化領(lǐng)域值得信任、有價(jià)值的長(zhǎng)期合作伙伴，公司提供的服務(wù)項(xiàng)目有：主機(jī)域名、網(wǎng)站空間、營(yíng)銷(xiāo)軟件、網(wǎng)站建設(shè)、鞏留網(wǎng)站維護(hù)、網(wǎng)站推廣。

1.簡(jiǎn)介

大數(shù)據(jù)開(kāi)發(fā)-表數(shù)據(jù)波動(dòng)、碼值分布波動(dòng)監(jiān)控 && 報(bào)警，是關(guān)于理論和設(shè)計(jì)部分，初步計(jì)算已經(jīng)寫(xiě)完，管理平臺(tái)部分，后續(xù)完善，本文主要針對(duì)模塊設(shè)計(jì)部分，整體模塊實(shí)現(xiàn)上是離線數(shù)據(jù)源的異步模塊，分為指標(biāo)跑批模塊，監(jiān)控報(bào)警模塊，平臺(tái)管理模塊，指標(biāo)跑批模塊和監(jiān)控報(bào)警模塊主要是基于離線數(shù)據(jù)的表的通訊，即不是耦合的架構(gòu)，分別是兩個(gè)例行的任務(wù),看下面的圖，

2.說(shuō)明

其中表設(shè)計(jì)了五張表，分別是指標(biāo)跑批記錄表，報(bào)警跑批記錄表，和MySQL表監(jiān)控配置表，報(bào)警配置表，分布字段配置表，指標(biāo)跑批和監(jiān)控跑批不直接任務(wù)依賴，而是通過(guò)指標(biāo)跑批記錄表，直接產(chǎn)生報(bào)警跑批記錄

3.代碼實(shí)現(xiàn)

整個(gè)項(xiàng)目目錄結(jié)構(gòu)如下圖：

resource: 配置文件

common: 一些公共的模塊，Builder是發(fā)送消息構(gòu)建器，F(xiàn)ather是Spark項(xiàng)目的公共代碼

rules: 下面有5個(gè)指標(biāo)的規(guī)則，分別是檢查分區(qū)是否存儲(chǔ)，檢查分區(qū)數(shù)量是否大于某個(gè)值，檢查分區(qū)數(shù)量波動(dòng)，檢查分布，檢查分布大向量波動(dòng)

utils: 里面放的是一些工具，比如日期處理工具類，表格式處理工具，sql處理工具等

Monitor: 指標(biāo)跑批的主類

SunRobot: 報(bào)警跑批的主類入庫(kù)

4.Monitor類說(shuō)明

rule的一些實(shí)現(xiàn)，不細(xì)說(shuō)了，根據(jù)源代碼很好看懂，而Monitor是怎么根據(jù)這些規(guī)則，生成對(duì)應(yīng)的流水，主要實(shí)現(xiàn)代碼如下：

package com.hoult

import com.beust.jcommander.JCommander
import com.hoult.common.Father
import com.hoult.rules.{Rule1, Rule2, Rule3, Rule4, Rule5, TableMonitorConf, TableMonitorRecord}
import com.hoult.utils.{DateTool, PropertiesUtils}
import org.apache.spark.sql.Dataset

import scala.collection.mutable.ListBuffer

object Monitor extends Father {

  val mysqlProps = PropertiesUtils.getMysqlProps()
  var broadTableConfs: Dataset[TableMonitorConf] = null

  def main(args: Array[String]): Unit = {

    val info: ObserverArgs = new ObserverArgs
    println("入?yún)?: " + args.mkString(","))
    JCommander.newBuilder().addObject(info).build().parse(args.toArray: _*)

    //廣播配置表
    prepare()

    //生成表 * 規(guī)則 個(gè) dataframe

    val defaultTableConf = spark.sql("select * from table_monitor_conf where db_table_name ='default.default'").as[TableMonitorConf].collect().take(1)(0)
    var ll: ListBuffer[Dataset[TableMonitorRecord]] = ListBuffer[Dataset[TableMonitorRecord]]() //所有規(guī)則一起跑

    //默認(rèn)值填充
    val tConfs = tableConfArray.map( conf => {
      TableMonitorConf(
        if(conf.db_table_key == null) defaultTableConf.db_table_key else conf.db_table_key,
        conf.db_table_name,
        if (conf.table_charge_people == null) defaultTableConf.table_charge_people else conf.table_charge_people,
        if (conf.done_path == null) defaultTableConf.done_path else conf.done_path,
        if (conf.where_condition == null) defaultTableConf.where_condition else conf.where_condition,
        if (conf.if_done == null) defaultTableConf.if_done else conf.if_done,
        if (conf.if_check_partition == null) defaultTableConf.if_check_partition else conf.if_check_partition,
        if (conf.if_check_partition_count == null) defaultTableConf.if_check_partition_count else conf.if_check_partition_count,
        if (conf.if_check_partition_count_fluctuates == null) defaultTableConf.if_check_partition_count_fluctuates else conf.if_check_partition_count_fluctuates,
        if (conf.if_check_distribute == null) defaultTableConf.if_check_distribute else conf.if_check_distribute,
        if (conf.if_check_distribute_fluctuates == null) defaultTableConf.if_check_distribute_fluctuates else conf.if_check_distribute_fluctuates
      )})

    //遍歷所有規(guī)則
    for (elem <- tConfs) {
      //規(guī)則1
      if ("1".equals(elem.if_check_partition)) {
        ll +:= Rule1.runRule(elem.db_table_name, elem.db_table_key, elem.where_condition, info.runDay)
      }

      //規(guī)則2
      if ("1".equals(elem.if_check_partition_count)) {
        ll +:= Rule2.runRule(elem.db_table_name, elem.db_table_key, elem.where_condition, info.runDay)
      }

      //規(guī)則3
      if ("1".equals(elem.if_check_partition_count_fluctuates)) {
        ll +:= Rule3.runRule(elem.db_table_name, elem.db_table_key, elem.where_condition, info.runDay)
      }
      //規(guī)則4
      if ("1".equals(elem.if_check_distribute)) {
        ll +:= Rule4.runRule(elem.db_table_name, elem.db_table_key, elem.where_condition, info.runDay)
      }

      //規(guī)則5
      if ("1".equals(elem.if_check_distribute_fluctuates)) {
        ll +:= Rule5.runRule(elem.db_table_name, elem.db_table_key, elem.where_condition, info.runDay)
      }
    }

    if (ll.size == 0)
      return
    ll.reduce(_.union(_)).select(
      "db_table_key",
      "db_table_name",
      "check_data_time",
      "rule_name",
      "rule_result",
      "rule_error",
      "checked_partition"
    ).createOrReplaceTempView("temp_table_rule_records")

    val partition = DateTool.getLatest30minutePatition
    spark.sql("set hive.reduce.tasks=1")
    spark.sql(s"insert overwrite table table_monitor.table_rule_records partition(dt=${info.runDay},hm=$partition) select * from temp_table_rule_records")

  }

  def prepare(): Unit = {
    import spark.implicits._
    //1.基礎(chǔ)配置表緩存到集群 table_monitor_conf
    val tableConfs: Dataset[TableMonitorConf] = spark.read.jdbc(mysqlProps.getProperty("url"), "table_monitor_conf", mysqlProps).as[TableMonitorConf].cache()
    tableConfs.createOrReplaceTempView("table_monitor_conf")

    //2.配置表緩存到集群 table_monitor_distribute_conf
    spark.read.jdbc(mysqlProps.getProperty("url"), "table_monitor_distribute_conf", mysqlProps).cache().createOrReplaceTempView("table_monitor_distribute_conf")

  }

}

整理流程就是讀配置表的信息，包括設(shè)置默認(rèn)參數(shù)，最后就是調(diào)用拿出來(lái)的配置表的信息和規(guī)則的信息

5.SunRobot說(shuō)明

這個(gè)模塊就是報(bào)警以及生成攔截done文件的模塊，主要功能就是根據(jù)前面的指標(biāo)流水以及配置表的配置的表元信息進(jìn)行比對(duì)，看看是否滿足check要求，如果滿足了就生成done，如果不滿足就生成undone, 如果配置了報(bào)警，就會(huì)根據(jù)報(bào)警規(guī)則進(jìn)行報(bào)警，暫且只有發(fā)送到通訊工具一項(xiàng)，主要代碼如下：
