Unable to execute custom ambari alert script.

[#1]

@jsensharma 

I followed all the steps but I m not seeing the custom alerts.

I tried executing the script but it is throwing below error: 

[root@xxxxx host_scripts]# python test_alert_disk_space.py
Traceback (most recent call last):
File "test_alert_disk_space.py", line 8, in <module>
from resource_management.core.logger import Logger
ImportError: No module named resource_management.core.logger

Ambari Version 2.7.3.0

HDF: 3.4.1

Please make sure to set the "PYTHONPATH" variable to point to ambari agent lib directory as following:

# export PYTHONPATH=/usr/lib/ambari-agent/lib:$PYTHONPATH
# python test_alert_disk_space.py

.

So I have to use export statement while running from console only, correct me if I am wrong.

Correct when we manually want to run such scripts which are dependent on ambari agent python modules then Yes, we will have to manually export PYTHONPATH.
Ambari agent automatically sets the necessary module paths in the python path when it tries to executed such scripts.
