Python Jenkins-jenkins模块获取jobs的执行状态操作

PS 参考博文，致谢 ：https://www.jb51.net/article/186336.htm

一、获取Jobs的当前状态

server_1 = jenkins.Jenkins('http://%s:%s@192.168.37.134:8081/',username, password)

# 获取状态前先确认2019文件夹下的get_node_list任务是否存在：
server_1.assert_job_exists('2019/get_node_list')


# 获取最后一次完成（不包括执行中的）的job任务执行number：
server_1.get_job_info('2019/get_node_list')['lastCompletedBuild']['number']


# 查看job状态(SUCCESS/FAILURE/ABORTED)：
server_1.get_build_info('2019/get_node_list',3)['result']
server_1.get_build_console_output('2019/get_node_list',7).split('\n')[-2].split(':')[-1].strip()


# 启动jobs：
server_1.build_job('2019/get_node_list')

• 在job执行结束前使用server_1.get_build_console_output(‘2019/get_node_list',7).split('\n')[-2].split('😂[-1].strip()获取的状态信息不符合预期。
• job状态应该还包括running，pending状态，那么获取job的当前状态正确姿势如下：

job_name = '2019/get_node_list'
def get_jobs_status(job_name,server):
  try:
    server.assert_job_exists(job_name)
  except Exception as e:
    print(e)
    job_statue = '1'
  #判断job是否处于排队状态
  inQueue = server.get_job_info(job_name)['inQueue']
  if str(inQueue) == 'True':
    job_statue = 'pending'
    running_number = server.get_job_info(job_name)['nextBuildNumber']  
  else:
    #先假设job处于running状态，则running_number = nextBuildNumber -1 ,执行中的job的nextBuildNumber已经更新
    running_number = server.get_job_info(job_name)['nextBuildNumber'] -1
    try:
      running_status = server.get_build_info(job_name,running_number)['building']
      if str(running_status) == 'True':
        job_statue = 'running'
      else:
        #若running_status不是True说明job执行完成
        job_statue = server.get_build_info(job_name,running_number)['result']
    except Exception as e:
      #上面假设job处于running状态的假设不成立，则job的最新number应该是['lastCompletedBuild']['number']
      lastCompletedBuild_number = server.get_job_info(job_name)['lastCompletedBuild']['number']
      job_statue = server.get_build_info(job_name,lastCompletedBuild_number)['result']

  return job_statue,running_number

• 注意：
  • 可能还存在下图的情况，这个时候获取的是26的状态，这时候也许你想获取25的状态，26是不小心误操作触发的，这个时候任务的最新状态也许就无法满足预期要求，或者是支持并发构建的job场景中就不适用了，关键还是需要结合应用场景制定对应的方案。

二、统计Jobs的执行成功率和平均执行时间

• 统计场景说明：
  • 设计了一个统计job执行成功率的工程，主要从执行时间以及视图两个维度来划定需要统计的jobs及jobs对应的运行范围。
  • 在这里我在job里面添加了DAYS和VIEWS两个参数：
    • DAYS：默认统计最近一天的运行情况，如果执行的时候输入的是0则代表统计所有的运行情况。
    • VIEWS：对应的是视图名称，“2019-1,test”代表统计这两个视图的运行情况

• 执行成功后以表格形式列出统计的数据，表头如下 ：
  

• 列出了序号、视图名称、job名称、job执行成功的平均执行时间、job执行成功次数、总的执行时间、job执行成功率

• job执行演示：

• 执行构建时配置的参数如下 ：

• job_data任务的主要执行内容如下：

• 执行成功后查看HTML_Report统计的数据如下：
  

• get_job_data.py源码如下：
