zabbix Distributed
Zabbix proxy Use scenarios :
Monitoring remote area equipment Monitor local network instability areas
When monitoring thousands of devices , reduce zabbix server The load of
Simplify the maintenance of Distributed Monitoring .
When thousands of servers are monitored , Generally monitored Server There will be a lot of pressure , So there is distributed monitoring to share Server pressure , That is, add a proxy server , Function and Server almost , The proxy server collects agent The monitoring data is returned to Server To deal with .
zabbix proxy Just one tcp Connect to zabbix server, So just add a rule to the firewall zabbix proxy The database must be connected with server Separate , Otherwise the data will be destroyed
zabbix proxy After collecting the data , First, cache the data locally , And then pass it on to zabbix server, In this way, data will not be lost due to any temporary communication problems with the server . This time is by proxy Parameters in the configuration file ProxyLocalBuffer and ProxyOfflineBuffer decision
Experiment preparation
