 Description   

Hi,

First issue, I don't really know how to contribute.

Steps to reproduce:

  1. Execute Apache: Get status item on host with mod_status enabled

Result:

  1. Get only "Apache" in ServerVersion field if there is a / in the server version (ex: Apache/2.4.53 (Debian) OpenSSL/1.1.1n)

Expected:

Solved by modifying preprocessing Javascript //Convert apache to JSON:

Line 12, change

var line = lines[i].match(/([A-z0-9 ]+): (.*)/);

by

var line = lines[i].match(/([A-z0-9 ]+): (.*$)/);

Thanks.

Would it be possible to get a full response from the server-status?auto.

Also Zabbix agent 2 debug log and the response of the 
zabbix_agent2 -t web.page.get[<ip_address>/server-status?auto]

As two possibilities come to mind either the response contains a different Server key and so the ServerVersion key is overwritten as per the JS logic from pre-processing. Or the other possibility is that if Zabbix is built from source the wrong libpcre is uses and the match does not work correctly.
