Zabbix Enterprise Monitoring

You cannot fix what you cannot see. We make sure you see everything.

Most monitoring solutions give you partial visibility. They check whether a website loads from one location, or alert when a server CPU crosses a threshold, but they leave gaps: the internal service that nobody is watching, the database that is degrading slowly before it fails completely, the network path between two private systems that silently started dropping packets. Node runs an enterprise Zabbix platform with public monitoring probes deployed across AWS regions for external web checks, private agents deployed inside your networks for internal visibility, and a fully managed monitoring operations layer that means alerts go to someone who acts on them.

What Zabbix is and why it is the right choice at enterprise scale

Zabbix is an open source enterprise monitoring platform that has been in production use at large organisations for over two decades. It monitors servers, network devices, cloud infrastructure, containers, databases, applications and services - anything that exposes metrics, logs or status information can be monitored by Zabbix. It scales from monitoring a handful of systems to hundreds of thousands of devices in a single deployment.

Unlike SaaS monitoring tools with per-host or per-metric pricing that becomes expensive at scale, Zabbix runs on your own infrastructure (or ours) with no per-device licensing costs. You add as many hosts, checks and metrics as your environment requires without a pricing conversation each time. Node runs Zabbix as a managed service, providing the platform, the operations team and the expertise - you get enterprise-grade monitoring without the overhead of running it yourself.

Our monitoring platform architecture

Node's Zabbix deployment is not a single server. It is a distributed, high-availability platform designed to monitor complex, multi-location environments reliably.

Zabbix server cluster - the core Zabbix server runs in a high-availability configuration with automatic failover. Monitoring does not pause when a node is taken down for maintenance or fails unexpectedly. The monitoring database runs on PostgreSQL with streaming replication, protecting historical metric data against hardware failure.

Distributed proxy architecture - Zabbix proxies extend the monitoring reach of the central server. Each proxy collects data from the systems in its network segment and forwards it to the central server, reducing the bandwidth requirements of monitoring across wide-area links and enabling monitoring of air-gapped or restricted network segments.

Public probes in AWS - we run monitoring probes deployed across multiple AWS regions for external web checks and synthetic monitoring. Your website, API endpoints, SSL certificates and public services are checked from geographically distributed locations, distinguishing between a genuine outage and a regional connectivity issue. A site that is unreachable from London but accessible from Frankfurt is a different problem from one that is down globally - our probe network tells you which.

Private network agents - for systems inside your network perimeter - servers, databases, internal applications, network devices - we deploy Zabbix agents or use agentless monitoring protocols (SNMP, IPMI, JMX, WMI) to collect metrics without requiring those systems to have public internet connectivity. Internal visibility is as comprehensive as external visibility.

What we monitor

Zabbix monitors the full stack. There are no gaps between layers and no blind spots between systems.

Web and application monitoring

HTTP/HTTPS web checks - availability, response time, response code and content verification for every public URL. We check that your pages load, that they return the expected content, that they load within acceptable time thresholds, and that they do not return errors. Checks run from multiple geographic locations simultaneously.

SSL certificate monitoring - certificates are monitored for expiry with configurable advance warning periods. A certificate expiring in 30, 14 and 7 days generates escalating alerts. Certificate chain validity, cipher suite configuration and HSTS headers are all checked.

API endpoint monitoring - REST and SOAP API endpoints are checked with configurable request payloads and response validation. We verify that your APIs respond correctly, not just that the port is open.

Transaction monitoring - multi-step synthetic transactions simulate real user journeys: load a page, submit a form, receive a response. If any step in the sequence fails or exceeds a time threshold, an alert fires. Your checkout flow, your login process and your critical user journeys are continuously validated.

Infrastructure monitoring

Servers and virtual machines - CPU, memory, disk I/O, disk space, network throughput, process status, log file monitoring and custom metric collection for Linux and Windows systems. Thresholds are configured per-system based on normal operating characteristics, not generic defaults.

Kubernetes and containers - pod health, node resource utilisation, container restart rates, persistent volume capacity and cluster-level metrics from Kubernetes clusters. We integrate Zabbix with your container platform to provide visibility at both the container level and the underlying infrastructure level.

Cloud infrastructure - metrics from AWS, Azure and GCP resources collected via their native APIs: EC2/VM instance health, RDS database performance, load balancer traffic and error rates, object storage capacity and Lambda function error rates.

Network devices - switches, routers, firewalls and load balancers monitored via SNMP for interface utilisation, error rates, BGP session status, VPN tunnel health and hardware sensor readings (temperature, power supply status, fan speed). Network visibility is as important as server visibility when diagnosing connectivity problems.

Database monitoring

Query performance - slow query detection, active connection counts, replication lag, cache hit rates, deadlock frequency and tablespace utilisation for PostgreSQL, MySQL, MariaDB, MSSQL and Oracle. Database problems surface before they become outages.

Replication monitoring - for database clusters and replicas, replication lag is monitored continuously. A replica falling behind its primary is caught early rather than discovered when a failover reveals stale data.

Capacity trending - disk space, index bloat, table growth rates and connection pool utilisation are trended over time so you can see capacity constraints coming weeks or months ahead rather than reacting to them.

Alerting and escalation

Monitoring that alerts to an inbox nobody reads is not monitoring. We configure alerting that reaches the right people with the right context at the right time.

Multi-channel alerting - alerts are delivered via email, SMS, Slack, Microsoft Teams, PagerDuty or any webhook-capable system. Critical alerts go to multiple channels simultaneously to ensure they are seen.

Escalation policies - alerts that are not acknowledged within a defined period escalate to the next level. An alert that goes unacknowledged for five minutes escalates from the on-call engineer to the team lead. One unacknowledged for fifteen minutes escalates further. Nobody sleeps through a production outage unnoticed.

Alert suppression and maintenance windows - planned maintenance is registered in Zabbix so alerts are suppressed for the duration and do not generate noise. Alert dependencies prevent a cascade of notifications when a network device failure causes all the servers behind it to appear unreachable simultaneously - you receive one alert about the network device, not fifty alerts about the servers.

Problem correlation - related problems are correlated into a single incident rather than generating individual alerts for each affected system. A database outage that impacts five application servers generates one correlated incident, not six separate alerts.

Dashboards and reporting

Zabbix provides visibility, but we make that visibility accessible to the people who need it - from engineers who need real-time operational data to executives who need a business-level availability summary.

Real-time operational dashboards - customisable dashboards for each team showing the systems they own: current status, recent problems, metric trends and active alerts. Engineers have the information they need without searching through irrelevant data.

Executive and service dashboards - high-level availability and performance summaries that show whether key services are meeting their SLAs, presented in a format that does not require infrastructure expertise to interpret.

Capacity planning reports - trend analysis of resource utilisation over time, projected to show when thresholds will be breached under current growth rates. Plan infrastructure investments based on data rather than guesswork.

SLA reporting - automatic calculation of service availability against defined SLA targets, with reports exportable for customer reporting or internal governance requirements.

Zabbix across your full infrastructure

Our Zabbix platform integrates naturally with the rest of Node's services. Kubernetes clusters managed as part of our cloud-native modernisation practice feed metrics directly into Zabbix. Apache Kafka, Apache Airflow and the rest of the automation stack are monitored at the application level. Keycloak authentication events are surfaced alongside infrastructure health. The result is a single pane of glass across your entire managed environment - not separate monitoring silos for each technology layer.
