# Zabbix Agent Zabbix Agent is a lightweight monitoring agent that reports host and system metrics to a Zabbix Server or Zabbix Proxy. It is open source and self-hosted, installable on Docker Hub, Kubernetes (Helm) and Unraid. Canonical page: https://ourlocalhost.com/app/59/zabbix-agent ## Description Zabbix Agent is a lightweight monitoring agent that reports host and system metrics to a Zabbix Server or Zabbix Proxy. It collects information such as load, memory, network, and disk usage from the monitored host. It is intended for hosts that already have access to an existing Zabbix deployment and need to expose host metrics for monitoring. ## Platform availability Available on 2 of 9 platforms: Unraid, Helm. ## Health score 51/100 (Fair), based on 4 of 4 factors. - Maintained: 68 (last commit 74 days ago) - Popular: 0 (0 GitHub stars) - Easy to install: 45 (2 install platforms, install notes, Docker image) - Light to run: 100 (128 MB minimum RAM, runs on ARM) ## Links - GitHub: https://github.com/zabqix/Zabbix-agent - Docker Hub: https://hub.docker.com/r/zabbix/zabbix-agent - Kubernetes (Helm): https://artifacthub.io/packages/helm/fermosit/zabbix-agent - Unraid: https://ca.unraid.net/apps/zabbix-agent-0xphl1g1v4bc5c?q=zabbix-agent - Official website: https://www.zabbix.com/ - Documentation: https://www.zabbix.com/documentation ## Common questions ### Can the agent monitor a host behind NAT or a restrictive firewall without opening an inbound port? Yes, active checks let the agent connect outward to the Zabbix server or proxy, retrieve item configuration, and send collected values. Passive checks instead require the server or proxy to connect to the agent. ### Where is the main Zabbix Agent configuration file and can it be split into fragments? The primary configuration file is zabbix_agentd.conf, normally under /etc/zabbix on Unix-like systems and with the agent service files on Windows. It can be split with Include directives, but included files must be readable, syntactically valid, and duplicate settings should be avoided. ### Why may the Zabbix server self-check fail in a containerized setup? The default item may look for localhost, which does not work normally inside containers. Change the item target to zabbix-agent so it points to the running Zabbix Agent container. ### Can newly installed Zabbix agents join an existing deployment automatically? Yes, once Zabbix is set up, newly installed agents can self-register on the Zabbix server. The server can apply the correct template based on a discovery rule. ## Alternatives - Beszel: A lightweight server monitoring hub with historical data, docker stats, and alerts. - Better Stack: AI-driven monitoring platform providing incident management, real-time logs, uptime, traces, error tracking, infrastructure analytics, and… - Datadog: Datadog Agent is an on-host monitoring agent that collects metrics, logs, and traces from hosts, containers, and Kubernetes clusters and se… - EdgeConnect: Dynatrace EdgeConnect is a secure bridge that links your local data centres to the Dynatrace cloud. - Icinga: Icinga is a fork of Nagios and is backward compatible. - LibreNMS: LibreNMS is a fully featured network monitoring system that discovers and monitors network devices, interfaces, and services. - Munin: Munin is a networked resource monitoring tool that can help analyze resource trends and "what just happened to kill our performance?&q… - Nagios: Nagios is an open-source monitoring system that checks hosts, network services, and IT infrastructure resources so IT administrators can id… - NetAlertX: NetAlertX is a self-hosted network presence scanner and alert framework that monitors Wi-Fi or LAN devices, detects new, disconnected, or c… - Netdata: Netdata is a real-time performance and health monitoring solution that helps you visualize and understand the behavior of your systems. - Observium: Observium is a free and open-source, autodiscovering network monitoring platform. - PHP Server Monitor: PHP Server Monitor checks whether your websites and servers are up and running. --- Source: Our Local Host (https://ourlocalhost.com/app/59/zabbix-agent), the self-hosted and open-source app directory.
