TCP 10051
Synopsis
- TCP port 10051 is officially registered as zabbix-trapper and is used by the Zabbix monitoring platform.
- Zabbix Server listens on 10051 to receive metrics and active check results from Zabbix Agent (active mode) and from the zabbix_sender utility, and to exchange data with Zabbix Proxies.
- Zabbix Proxy also uses 10051: in passive-proxy mode it listens on 10051, while in active-proxy mode it connects outbound to the Zabbix Server’s 10051.
- Real-world deployments (e.g., Zabbix 6.x on Linux and the official zabbix/zabbix-server Docker image) expose TCP 10051 for these functions.
