I've read about mikoomi. And I it is not suitable for me. I do not have access to secret key. I want to install and use zabbix server and agent itself on instances. Is it good idea? And here is the problem: during: yum install zabbix-server-pgsql zabbix-web-pgsql zabbix-agent I got: Error: httpd24-tools conflicts with httpd-tools Error: httpd24 conflicts with httpd How to complete installation successfully?
