how to test custom ambari alert

[#1]

I uset hdp 2.4 and ambari 2.2.1.1

I had custom an ambari alert and test on my test servers.

But when I copy it on mysql product environment, one server seems every thing is ok,and the other is show me :

'NoneType' object has no attribute 'modules' 

So, I try to the monitor script writen in pytthon.

When I run python monitor.py, it shows ok,but on the ambari-agent,it still wrong.

So is there a way to test the script and debug the monitor script??

What I don't clear is why on one server show me

'NoneType' object has no attribute 'modules'

,but the other is ok

I try to restart the ambari-agent,It show me ok

So terrible.
