Using https://git.zabbix.com/projects/ZBX/repos/zabbix/browse/templates/app/nginx_agent if nginx version changes, I get such email (headers):
Date: Sun, 12 Jul 2020 15:16:02 +0000 Subject: PROBLEM: Nginx: Version has changed (new version: 1.19.1) MIME-Version: 1.0
As you can see, Subject line is broken, so everything after it goes as email body and it is broken as well. It is because nginx response has Windows newlines (\r\n), as you can see by curl -v http://127.0.0.1/basic_status &> file.txt
The following patch fixes email subjects:
--- template_app_nginx_agent.xml.orig 2020-07-12 15:59:28.606663182 +0300 +++ template_app_nginx_agent.xml 2020-07-12 21:20:17.321393095 +0300 @@ -359,7 +359,7 @@ <preprocessing> <step> <type>REGEX</type> - <params>Server: nginx/(.+) + <params>Server: nginx/(.+(?<!\r)) \1</params> </step> <step>
