Zabbix - Configuration and optimization

Hi, this is a project with several phases, it's not just one time, but to go forward, I have to be very comfortable with the person that I am going to work with. 1st Phase very simple, and fast, for who has knowledge. - Configure Zabbix agent active, and configure key to use for example [UserParameter=CheckVPN[*],@echo off && for /f "tokens=3 delims==" %A IN ('ping -w 200 -n 1 $1 ^| find "Empfangen"') do for /f "tokens=1 delims=^, " %B IN ("%A") do echo %B], or other parameters in a windows server, in this case I would like to know if the vpn from this server is up and when is down to have an alert. - Start a specific Service in a windows server when the trigger from this service is activated, fig3 at attachment. when a windows service is stopped, I would like that zabbix automatically start it. 2nd Phase - Analyze Zabbix Server and optimize (mysqltunner, cron jobs, innobdb, index/small queries...) fig4. 3rd Phase - Configure SNMP - Configure proxy server (The tests that I did, instead of release zabbix server, the queue was more full than ever) 4th Phase -Zabbix API, How to use it.
