Antihost offers Linux VPS plans with full root access, unlimited traffic on a 1 Gbps port and a 14-day free trial.
Run Zabbix Agent 2 on the VPS, enable its built-in Docker plugin, link the official Linux template, and then choose passive or active checks according to your firewall and routing. Passive checks let the Zabbix server or proxy request data from the VPS; active checks let the VPS retrieve its configuration and send values outbound. After the first values appear in Monitoring → Hosts → Latest data, add triggers and notification actions for stopped containers, an unavailable Docker daemon, resource saturation, and filesystem pressure.
The procedure below assumes Zabbix 7.4 examples. Keep the agent compatible with the server; Zabbix recommends installing an agent of the same version as the server. The current Linux integration page states that the Linux by Zabbix agent template requires Zabbix agent 7.4 or newer.

What the monitoring path looks like
Zabbix describes the agent as “the process responsible for gathering data.” On a Docker VPS, the path is:
- The Zabbix Agent 2 service runs on the Linux host.
- Its built-in Docker plugin connects to the Docker daemon through a Unix socket or a controlled daemon endpoint.
- Docker item keys collect daemon, container, image, statistics, and data-usage values.
- Template items and low-level discovery create the host and container monitoring objects in Zabbix.
- Triggers evaluate those values and actions deliver alerts through the media configured for the responsible users.
Linking a Linux operating-system template alone does not guarantee container metrics. The Docker plugin must be able to query the daemon, and Docker items or discovery rules must be enabled and working.

Prerequisites and design decisions
- A Zabbix server or proxy that can exchange agent traffic with the VPS.
- Zabbix Agent 2 on the VPS, at a version compatible with the server. These examples use the 7.4 configuration model.
- Docker running on the VPS and an agent process that can reach the Docker daemon.
- A decision about passive or active checks before you create the host.
- A controlled plan for Docker socket access. Access to the Docker socket is highly privileged and can effectively provide root-equivalent control of the host.
- Media and action rules in Zabbix if alerts must reach people or an incident system.
Passive versus active checks on a VPS
Both modes collect the same kinds of Docker data, but they reverse who starts the connection. Choose the mode that matches your network path rather than treating one as universally better.
| Consideration | Passive checks | Active checks |
|---|---|---|
| Connection direction | The Zabbix server or proxy requests values from the agent. | The agent retrieves its configuration and sends collected values to the server or proxy. |
| Firewall model | Permit the server or proxy to reach the agent service on the VPS. | Permit outbound connections from the VPS to the server or proxy; no inbound agent connection is needed. |
| Reachability | Best when the monitoring side can route to the VPS directly. | Best when outbound VPS connectivity is easier to secure, such as behind NAT or a restrictive inbound firewall. |
| Hostname requirement | The host uses an agent interface address and port. | The frontend Hostname must exactly match the agent’s Hostname setting. |
| Failure visibility | An inbound path failure is visible when the server cannot poll the agent. | An outbound outage can prevent fresh values from arriving; configure appropriate nodata or availability alerting. |
| Operational simplicity | Simple in a flat, routable network, but requires an exposed inbound path. | Often simpler for isolated VPS networks, but depends on correct active-check identity and outbound routing. |
Use passive checks when the server can reach the VPS
Passive checks are a good fit when a private network, VPN, or proxy can reach the VPS reliably. Restrict the firewall rule to the monitoring server or proxy rather than opening the agent port to the public internet. If a proxy performs the polling, allow the proxy address and use the proxy in the host configuration.
Do these 3 things before closing this tab:
1Clear out junk files and repair common Windows errors2Scan for outdated or missing drivers - takes under a minute3Repair Windows errors before they cause bigger problemsUse active checks when outbound access is easier
Active checks are useful for a VPS behind NAT or with no acceptable inbound route. The agent contacts the configured server or proxy, downloads the list of active items, and submits values. Set the exact same string in the frontend Hostname field and the agent’s Hostname parameter; a mismatch prevents the agent from receiving its active-check configuration.
Account for NAT and outages
Passive checks need a return route from the server or proxy to the VPS, so address translation and changing public addresses can complicate them. Active checks avoid that inbound dependency, but an outbound firewall failure, DNS failure, or route outage stops updates. Use an availability or nodata policy that distinguishes a monitoring-path outage from a single container problem.
Choose how to install Agent 2
Agent 2 can be installed from distribution packages, compiled from source, or run as a container. The right choice depends on how you manage upgrades and how much host integration you need.
| Installation model | Strengths | Trade-offs to plan for |
|---|---|---|
| Distribution package | Native service supervision, standard configuration paths, and package-manager upgrades. | You must keep the Zabbix repository and package version aligned with the server and operating system. |
| Source compilation | Control over the build and installation location. | You own dependency management, service integration, upgrades, and rollback. |
| Agent 2 container | Image-based deployment and a consistent runtime across hosts. | The container still needs access to Docker’s daemon endpoint, persistent configuration, service supervision, and a deliberate upgrade and rollback process. |
The documented container deployment path lists Docker 1.12 or later and Docker Compose 2.24.0 or later as prerequisites. Those requirements are version-sensitive, so verify the current guide before standardizing a deployment. Official Zabbix images cover agents, Agent 2, servers, proxies, web frontends, the Java gateway, web service, and SNMP traps.

Install and configure Agent 2 on the VPS
1. Record versions and the network path
Record the Zabbix server or proxy version, the VPS distribution, the Docker Engine version, and the route used for agent traffic. Use an Agent 2 release compatible with the server; matching the server version is the recommended starting point. Decide whether the server/proxy will initiate connections or the VPS will initiate them before editing the agent configuration.
For the examples in this guide, use Zabbix 7.4 packages and a host name such as vps-docker-01. Replace that example with a stable identity used only once in your Zabbix inventory.
2. Install the Agent 2 package
After adding the official Zabbix 7.4 repository for your Linux distribution, install the Agent 2 package with the distribution’s package manager. On Debian or Ubuntu the package command is:
sudo apt update
sudo apt install zabbix-agent2On an RPM-based distribution, the equivalent package operation is:

Confirm that the installed binary is Agent 2 and that its service unit is present before proceeding. If you choose source compilation or a container instead, preserve the same identity, connectivity, Docker endpoint, and service-supervision decisions described below.
3. Set the agent identity and check mode
Edit the Agent 2 configuration, normally /etc/zabbix/zabbix_agent2.conf. Set only the parameters required by your selected mode.

Hostname=vps-docker-01
Server=monitoring.example.net
ServerActive=monitoring.example.netFor passive checks, Server identifies the permitted Zabbix server or proxy that may request data. Configure the VPS host in the frontend with an agent interface address reachable from that server or proxy.
For active checks, set ServerActive to the server or proxy endpoint that will provide the active-check configuration. The frontend Hostname must be exactly vps-docker-01. Active mode can be used without exposing an inbound agent interface, provided outbound routing and firewall rules permit the connection.

Agent 2 includes a built-in Docker plugin; Zabbix documentation labels it “Docker | Monitoring of Docker containers.” Configure the plugin to use the Docker daemon endpoint available on your host. For a standard local Unix socket, the setting is commonly represented as:
Plugins.Docker.Endpoint=unix:///var/run/docker.sockUse the endpoint syntax supported by the Agent 2 version you installed. A remote or TLS-protected daemon endpoint can be used when your architecture requires it, but protect credentials and certificates and avoid exposing an unauthenticated Docker API.
5. Grant controlled daemon access
The Agent 2 service account must be able to query Docker. One common approach is adding the service account to the Docker group:
sudo usermod -aG docker zabbixMembership in the Docker group is powerful: a process that can control the Docker daemon may be able to start privileged containers, mount host filesystems, or otherwise take control of the host. Treat this as a security boundary, not as a harmless read-only permission. Prefer a controlled daemon endpoint, an appropriately restricted proxy, or another least-privilege design where your environment supports one. If you use a socket mount for a containerized Agent 2, apply the same risk assessment; putting the socket inside a container does not remove the daemon’s authority.

After changing group membership, restart the service or the host so the service process receives its new supplementary groups. Validate access as the account that actually runs Agent 2, not only as your administrative shell.
6. Start the service and validate locally
sudo systemctl enable --now zabbix-agent2
sudo systemctl status zabbix-agent2
sudo journalctl -u zabbix-agent2 --no-pagerLook for a running service and for Docker-plugin errors in the journal. Confirm that the Docker daemon itself responds from the VPS and that the endpoint in the Agent 2 configuration matches the endpoint you tested. If your installation provides the agent test mode, use it to query a Docker key such as docker.ping before enabling broad discovery.
Create the VPS host in Zabbix
- Open Data collection → Hosts and choose Create host.
- Enter the VPS host name exactly as it appears in the agent configuration. This exact match is mandatory for active checks.
- Assign the host to the appropriate host group.
- For passive monitoring, add an agent interface with the address and port reachable from the Zabbix server or proxy. Use the agent’s configured port rather than assuming a public address is safe.
- For active-only monitoring, follow the current frontend guidance for leaving the agent interface unset when the host uses active checks.
- Link Linux by Zabbix agent for passive checks or Linux by Zabbix agent active for active checks.
- Select the correct Zabbix proxy if the VPS is monitored through one, then save the host.
The Linux template supplies operating-system monitoring. Docker container inventory and statistics still depend on a functioning Docker plugin and the Docker items or discovery rules you enable.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Collect Docker data with item keys and discovery
Agent 2 exposes Docker-specific keys for targeted items and discovery. Select only the data needed to answer an operational question; collecting every possible statistic can create unnecessary load and a large item count.
| Key | What it is used for |
|---|---|
docker.ping |
Checks whether the agent can reach the Docker daemon. |
docker.info |
Collects Docker daemon information. |
docker.containers |
Returns container information for inventory or summary monitoring. |
docker.containers.discovery |
Discovers containers so item and trigger prototypes can be created per container. |
docker.container_info |
Collects information about an individual container. |
docker.container_stats |
Collects an individual container’s runtime statistics. |
docker.images |
Collects Docker image information. |
docker.images.discovery |
Discovers images for per-image monitoring. |
docker.data_usage |
Collects Docker data-usage information. |
Start with a small operational set
Begin with docker.ping, container discovery, container information, and container statistics. Add image discovery and data-usage monitoring when image growth, layer churn, or disk pressure is part of your operating model. Discovery should create items for stable identifiers and remove stale objects according to a retention policy that fits your environment.
Verify values in the frontend
Open Monitoring → Hosts → Latest data, select the VPS, and filter for Docker keys. Confirm that the daemon check has a current value, that discovered containers appear, and that statistics update at the expected interval. A host can show an available agent while Docker items remain unsupported; inspect the item error text and Agent 2 journal separately.

Build alerts that answer operational questions
When a container stops
Use container discovery and an item prototype that records each container’s state. Create a trigger prototype that fires when a monitored production container is no longer running. Exclude intentionally stopped, one-shot, or maintenance containers with discovery filters, tags, host groups, or a separate policy; otherwise routine jobs can generate false incidents.
When Docker becomes unavailable
Alert on a failed docker.ping or equivalent unsupported Docker item. This catches a stopped daemon, a broken socket path, a permission change, or a TLS/endpoint error. Distinguish this condition from an individual container stop so responders know whether to inspect the daemon, the Agent 2 service, or the workload.
When CPU or memory usage spikes
Use docker.container_stats values and trigger prototypes for sustained rather than momentary saturation. Define the threshold and evaluation window according to the workload’s normal behavior. A short sampling interval with a sustained-duration condition is usually more actionable than alerting on one transient sample.
When filesystem pressure rises
Combine Docker data-usage values with the Linux filesystem metrics supplied by the operating-system template. Alert before the filesystem is full, because image layers, writable container layers, logs, and package caches can consume the remaining space quickly. Include the affected mount point and container or image identity in the event name where the item supports it.
Deliver notifications deliberately
Configure media for the responsible users, then create actions that route events by severity, host group, tags, or service ownership. Test a safe condition and confirm the event appears under Monitoring → Problems, that recovery closes the event, and that the intended notification is delivered. Do not rely on a trigger alone; an action and usable media are required for a human notification.

Quick Recap
Validation and troubleshooting
| Symptom | Likely area | Checks to perform |
|---|---|---|
| The host is unavailable in passive mode | Routing or firewall | Verify the server/proxy can reach the VPS agent address and port, confirm the interface address in the host, and inspect the Agent 2 service status. |
| Active checks show no data | Identity or outbound path | Compare the frontend Hostname with the agent’s Hostname character for character, verify ServerActive, and inspect the Agent 2 journal for connection or configuration errors. |
| Linux metrics work but Docker items are unsupported | Plugin endpoint or permissions | Check the Docker endpoint, test daemon access as the Agent 2 service account, confirm socket or TLS permissions, and review plugin errors in the journal. |
| Discovery returns no containers | Discovery configuration | Confirm docker.containers.discovery is enabled, the Docker daemon has containers to return, and filters are not excluding every result. |
| Some containers never alert | Prototype or filtering policy | Inspect the discovered item and trigger prototypes, verify the container is included by the discovery filter, and check that the trigger is not disabled or suppressed by maintenance. |
| Values stop during a network outage | Selected check mode | For passive checks, test the inbound route from the server/proxy. For active checks, test outbound DNS, routing, firewall rules, and the configured active endpoint; review the nodata policy. |
Operate the setup safely over time
- Keep Agent 2 aligned with the Zabbix server version and review compatibility before upgrading either side.
- Use the narrowest Docker endpoint and network exposure possible. Never publish an unauthenticated Docker API to the internet.
- Review Docker group membership and socket mounts during security audits; remove access when the monitoring design changes.
- Control discovery scope so short-lived build containers and test workloads do not create permanent monitoring noise.
- Set update intervals and retention to match the operational decision each metric supports.
- Test both problem and recovery paths after template, plugin, firewall, or Docker upgrades.
- Document whether the server or a proxy owns the connection and which firewall direction is expected; this prevents a later network change from silently disabling monitoring.
A practical rollout sequence
- Confirm the Zabbix server version, VPS distribution, Docker version, and preferred connection direction.
- Install the compatible Agent 2 package, source build, or container deployment.
- Configure the agent identity and Docker endpoint.
- Grant and validate controlled Docker access for the Agent 2 service account.
- Start Agent 2 and inspect its status and journal.
- Create the host, choose the matching Linux template, and configure the passive interface or active-only identity.
- Check Docker keys and discovery in Monitoring → Hosts → Latest data.
- Create stopped-container, Docker-daemon, resource, and filesystem conditions with appropriate filters.
- Exercise a safe test condition, verify the event in Monitoring → Problems, and confirm notification and recovery.
