zabbix 3.2 - external script not working

Question

I have installed zabbix and running an external script - here is the steps I followed :

1. created a /etc/zabbix/externalscripts directory with correct rights
2. copied the script to this directory,
3. On web interface Administration -> Scripts -> new script
   In the commands section - > /usr/lib/zabbix/externalscripts/check.py https://mywebsite.com
4. Also create an item with type External Check and key is the file name of the script check.py and type of information is Numeric
5. Create a graph - > added the item I created above to plot - but the status already says Not Supported. If I change the type to character it never shows up in the items.

So now I get an error in the logs

ÏndexError:list index out of range]is not suitable for value type [numeric unsigned] and data type [decimal]

What I have checked:

I ran the script from the command prompt and it executes with the result:

OK, Total Resp Time: 8334.55ms;|8321.55 

I am not sure what else I need to check. Have changed the type to Float etc without any help.
The permissions to the directory is fine.
Any help would be appreciated.

Answer 1

First, there was no need to add Administration -> Scripts for external checks.

Second, if your script returns "OK, Total Resp Time: 8334.55ms;|8321.55", that is not a number and cannot be put in a numeric item and you will not be able to see a graph of such a string, of course.

Third, the error when running it manually looks like yet another problem. Make sure two things are covered when you run it manually:

• run it as the Zabbix user
• make sure there are no environment variables that affect the script behaviour; if there are, handle that in the script itself
