Primary goal is not to make all plugins available here but to be able to use any plugin and decentralized development.
If you are maintainer of some external check, it is enough to create zaf file in your repo and use zaf installer everywhere. If you are maintainer of some external check, it is enough to create zaf file in your repo and use zaf installer everywhere.
Next to this, this tool can even communicate with Zabbix API with *NO dependencies* to high level languages. Shell, sed and awk only.
## Motivation ## Motivation
Did you install lot of zabbix agents and try to setup similar common user parameters? Do you want to setup them all? Do you want to change some zabbix agent options on lot of system? Do you want to write your own simple check or discovery rule for zabbix and it is nightmare to deploy same script on more zabbix agents? Are you tired searching some system specific agent check and setup them individualy? Did you install lot of zabbix agents and try to setup similar common user parameters?

Do you want to write your own simple check or discovery rule for zabbix and it is nightmare to deploy same script on more zabbix agents? Are you tired searching some system specific agent check and setup them individualy? Do you want to auto simple backup all hosts in your zabbix to xml files? Or do you want to do some scripting on host depending on Zabbix server configuration?
