Celery-管理与监控

1. 监控和管理Workers

1.1 将celery实例放入shell
[root@node2 app]# celery -A tasks shell
Python 3.6.5 (default, Oct 23 2019, 12:55:54) 
Type 'copyright', 'credits' or 'license' for more information
IPython 7.8.0 -- An enhanced Interactive Python. Type '?' for help.

In [1]: app                                                                                                                          
Out[1]: <Celery tasks at 0x7ff7dddbdc18>

In [2]: add.delay(1,2)                                                                                                               
Out[2]: <AsyncResult: c5cfd00f-8b11-4408-95e2-241f2f3d5521>
1.2 查看任务的结果
[root@node2 app]# celery -A tasks  result c5cfd00f-8b11-4408-95e2-241f2f3d5521

1.3 从所有已配置的任务队列中清除消息
[root@node2 app]# celery -A tasks  purge
WARNING: This will remove all tasks from queue: celery.
         There is no undo for this operation!

(to skip this prompt use the -f option)

Are you sure you want to delete all tasks (yes/NO)? yes
No messages purged from 1 queue

  

您还可以使用-Q选项指定要清除的队列

$ celery -A proj purge -Q celery,foo,bar

并使用-X选项排除清除队列

  $ celery -A proj purge -X celery


1.4 列出活动的任务

  celery -A tasks inspect active
