Python-jenkins模組獲取jobs的執行狀態操作
阿新 • • 發佈：2020-05-12
1 獲取jobs的當前任務狀態
server_1 = jenkins.Jenkins('http://%s:%[email protected]:8081/',username,password)
獲取狀態前先確認2019資料夾下的get_node_list任務是否存在：
server_1.assert_job_exists('2019/get_node_list')
獲取最後一次完成（不包括執行中的）的job任務執行number：
server_1.get_job_info('2019/get_node_list')['lastCompletedBuild']['number']
檢視job狀態(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()
啟動jobs：
server_1.build_job('2019/get_node_list')
在job執行結束前使用server_1.get_build_console_output(‘2019/get_node_list',7).split('\n')[-2].split(':')[-1].strip()獲取的狀態資訊不符合預期。
job狀態應該還包括running，pending狀態，那麼獲取job的當前狀態正確姿勢如下：
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'
#判斷job是否處於排隊狀態
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:
#先假設job處於running狀態，則running_number = nextBuildNumber -1,執行中的job的nextBuildNumber已經更新
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說明job執行完成
job_statue = server.get_build_info(job_name,running_number)['result']
except Exception as e:
#上面假設job處於running狀態的假設不成立，則job的最新number應該是['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：
可能還存在下圖的情況，這個時候獲取的是26的狀態，這時候也許你想獲取25的狀態，26是不小心誤操作觸發的，這個時候任務的最新狀態也許就無法滿足預期要求，或者是支援併發構建的job場景中就不適用了，關鍵還是需要結合應用場景制定對應的方案。
2 統計jobs的執行成功率和平均執行時間
統計場景說明：
設計了一個統計job執行成功率的工程，主要從執行時間以及檢視兩個維度來劃定需要統計的jobs及jobs對應的執行範圍。
在這裡我在job裡面添加了DAYS和VIEWS兩個引數：
**DAYS：**預設統計最近一天的執行情況，如果執行的時候輸入的是0則代表統計所有的執行情況。
**VIEWS：**對應的是檢視名稱，“2019-1,test”代表統計這兩個檢視的執行情況
對應的檢視如下：
執行成功後以表格形式列出統計的資料，表頭如下
列出了序號、檢視名稱、job名稱、job執行成功的平均執行時間、job執行成功次數、總的執行時間、job執行成功率
job執行演示：
執行構建時配置的引數如下
job_data任務的主要執行內容如下：
執行成功後檢視HTML_Report統計的資料如下：
get_job_data.py原始碼如下：
