I would like help with getting a python event handler working which uses boto3. I have tried the script without being caused by an event and it works without any errors.

within my Python script:

Code: Select all

import boto3

I am getting the response below in the event logs:

Code: Select all

wproc: stderr line 04: ImportError: No module named boto3

How would I go about making this work?

Are you testing as the nagios user?
Is the handler running on the nagios host or remote hosts?

Yes, I am testing as a Nagios user and the event handler is running on the Nagios host where I am testing. To clarify I am using nagios core as I previously didn't mention.

More info:
Global event handler enabled and set up. working and tested before.

Code: Select all

define command {
    command_name    test
    command_line    /usr/local/nagios/libexec/eventhandlers/test.py $HOSTNAME$ $HOSTSTATE$
}

within my python script:

Code: Select all

#!/usr/bin/python
import sys
import boto3

I have used sys.argv to test the python script to add the macros to a file which worked with no errors.

I have boto3 installed:

Code: Select all

~$ pip show boto3
