db versions for zabbix server and proxy

[multazim]

HI, Do i need to have same mysql db major and minor versions for zabbix server and zabbix proxy ?
Also does zabbix proxy always keep all the data in its local db or does it delete the data from its local db after transferring data to zabbix server?

Hi,

No, you don't need to have the same versions for Server and Proxy databases. Furthermore, they can even be different types, e.g. server on MySQL and proxy on SQLite. That does not matter because the protocol how data is transmitted between them is identical in all cases.

Proxy by default deletes the data every hour. If you want to extend the time how much proxy buffers in case server is not reachable, look for ProxyOfflineBuffer setting in proxy configuration file.
