Issue when using external script to monitor certificate expiration

[Scrabbi]

Hello,

I have created a small script to check how many days I have left before my website certificates expires. When I execute my script using the user "zabbix" (which is the one used when an external script is used if I understood well) on my zabbix server, the script works fine and I get the number of days before expiration. However, once I create a host with a template, I get " Could not read certificate from /tmp/tmp.xxxxxx unable to load certificate 0".


Here you can find the script and the item :
The name of the host is "mysite.com" and is monitored by my zabbix server :
I found the script here : https://askubuntu.com/questions/1198...s-in-a-website



I did a bit of troubleshooting, and when I execute the script form my server, the tmp file is created and contains the certificate, but if it's from the item, the tmp file is empty.

I don't really know how to go from here, any help would be greatly appreciated.

I am no linux admin, but I think there might be a difference, if script is executed as logged in user from command line and as background process by same user... There can be difference in env vars, shell etc.. missing PATH etc...
