# Zabbix Proxy Design
|
||
|
|
|
||
|
|
## Purpose
|
||
|
|
|
||
|
|
Zabbix proxies reduce dependency on direct connectivity between the central server and monitored hosts. They are useful for client networks, segmented environments, remote sites, and maintenance windows.
|
||
|
|
|
||
|
|
## Active Proxy
|
||
|
|
|
||
|
|
- Proxy connects to the Zabbix server.
|
||
|
|
- Good for restricted networks where inbound access to the proxy is not allowed.
|
||
|
|
- Hosts can use active agent checks against the proxy.
|
||
|
|
- Main operational checks: proxy last seen, delayed values, local DB size, config sync.
|
||
|
|
|
||
|
|
## Passive Proxy
|
||
|
|
|
||
|
|
- Zabbix server connects to the proxy.
|
||
|
|
- Useful when central server can reach the proxy network.
|
||
|
|
- Requires firewall rules from server to proxy.
|
||
|
|
- Main operational checks: proxy listener, network latency, poller load.
|
||
|
|
|
||
|
|
## Operational Signals
|
||
|
|
|
||
|
|
- Proxy queue growth.
|
||
|
|
- Unsupported items after template changes.
|
||
|
|
- Agent unreachable or active checks delayed.
|
||
|
|
- Proxy DB growth during WAN outage.
|
||
|
|
- Config sync failures after maintenance.
