zabbix_agentd is the Linux agent daemon used to monitor Linux boxes and send the data to the zabbix server. Zabbix offers advanced monitoring, alerting and visualization features, including distributed monitoring, auto-discovery, notifications, etcetera. zabbix_agentd needs to run under its own user/group. This has been assigned to the following by SlackBuilds.org, but feel free to change it on your system for consistency with local assignments. User: zabbixagent UID: 266 GID: 266 group: zabbixagent GID: 266 You can pass alternate values for the user and group using ZABBIXAGENTUSER and ZABBIXAGENTGROUP variables when running the build script. zabbix_agentd needs another user/group to cooperate with other Zabbix deamons, like zabbix_server or zabbix_proxy. This has been assigned to the following by SlackBuilds.org, but feel free to change it on your system for consistency with local assignments. User: zabbix UID: 228 GID: 228 group: zabbix GID: 228 You can pass alternate values for the user and group using ZABBIXUSER and ZABBIXGROUP variables when running the build script.
