What is infrastructure monitoring

Know What Is Happening Before It Becomes an Incident

Infrastructure monitoring tracks the health, availability and performance of servers, network devices, services and other infrastructure components.

Instead of discovering issues after customers are affected, monitoring surfaces abnormal resource usage, service failures, connectivity problems and infrastructure events earlier, so your team can act sooner.

  • Collect

    Gather health and performance metrics

  • Analyse

    Identify abnormal values and failure conditions

  • Alert

    Notify responsible teams when thresholds trigger

  • Respond

    Use monitoring data to investigate and resolve

Monitoring architectureServers and network devices are the source. The monitoring system collects metrics and checks, analyses them against thresholds and trends, and triggers alerts and response. Alerts are classified as info, warning, high or critical.SOURCEServersNetwork devicesCOLLECTMonitoringMetrics & checksANALYSEThresholdsTrendsACTIONAlertsResponseALERT SEVERITYINFOStatus eventWARNINGNearing limitHIGHDegradationCRITICALAct nowLower severityHigher severity

Uptime monitoring

Websites, IPs, ports and supported services for availability.

Service monitoring

Critical services and application endpoints, where supported.

Performance monitoring

System metrics that reveal degradation and capacity pressure.

Custom monitoring

Policies designed around specialised infrastructure and applications.

Infrastructure metrics

The Metrics That Matter Most

Core resource and availability metrics give early warning of problems and a historical record for capacity decisions.

  • CPU usage

    Processor utilisation and sustained load.

  • Memory usage

    Memory pressure and unusual consumption.

  • Disk usage

    Disk capacity and supported storage metrics.

  • Bandwidth and interfaces

    Network utilisation, link status and traffic trends.

  • Availability

    Whether critical infrastructure remains reachable.

  • Custom metrics

    Additional metrics based on your operating environment.

Monitoring and management

Monitoring vs Server Management

Monitoring tells you what is happening. Server management acts on it. The two work best together.

Monitoring insights

Enterprise Infrastructure Monitoring: Checks, Alerts and Capacity

An overview for IT and operations teams: what to monitor, how to design alerts that teams act on and how monitoring data supports capacity planning.

Uptime and service checks

Resource metrics show how systems are performing; availability checks confirm whether they can actually be reached. A complete monitoring design uses both.

CheckWhat it monitors
Website monitoringReachability of supported public web endpoints
IP monitoringReachability of critical public or private endpoints
Port monitoringSupported ports used by important services
Service checksSupported system and application services
Availability trendsAvailability patterns over time
Custom health checksImportant operational dependencies

Designing alert thresholds

Alert policies are designed around severity, thresholds, duration and escalation requirements. A clear severity model helps teams prioritise:

SeverityMeaning
InfoOperational status event
WarningResource or threshold approaching its limit
HighService degradation or a significant issue
CriticalImmediate operational attention required

Well-designed thresholds include a duration condition, so a brief spike does not trigger an alert. Setting a warning level below the critical level gives teams time to act before users are affected, and keeps alert volume low enough that every notification is taken seriously.

Escalation planning

An alert is only useful if it reaches someone who can act on it. An escalation plan defines:

  • Who receives each severity level
  • Which notification channels are used
  • When an unacknowledged alert is escalated, and to whom
  • Which alerts require immediate action and which can wait

Where hands-on response is required, monitoring can be combined with server management.

Performance and capacity trends

Historical monitoring data reveals recurring resource pressure, growth trends and potential bottlenecks: sustained CPU utilisation, memory pressure, disk capacity growth, bandwidth trends and service degradation.

These signals support better capacity and upgrade decisions, and can feed directly into infrastructure consulting and capacity planning.

Preparing for a monitoring deployment

The following information helps our infrastructure team design monitoring efficiently:

  • Servers, network devices and services to be monitored
  • Infrastructure type: dedicated, VPS, colocation, private cloud or hybrid
  • Critical services, ports and endpoints
  • Alert recipients and escalation requirements
  • Whether server or network management is also required

Share these details through the monitoring request form and our team will recommend a monitoring design.

Ask Our Infrastructure Team
What is infrastructure monitoring?

Infrastructure monitoring tracks the health, availability and performance of servers, networks and supported services.

Can you monitor dedicated servers?

Yes. Eligible dedicated servers can be monitored for availability, resource utilisation and supported system metrics.

Can network devices be monitored?

Yes. Supported routers, switches, interfaces and network endpoints can be included in monitoring environments.

Can CPU, memory and disk usage be monitored?

Yes. Supported servers can be monitored for CPU, memory, disk, network and other infrastructure metrics.

Yes. Alert thresholds can be planned according to supported metrics and operational requirements.

Can websites and public services be monitored?

Yes. Supported public endpoints, ports and services can be monitored for reachability and availability.

Is monitoring the same as server management?

No. Monitoring focuses on visibility and alerting, while server management includes operational actions such as configuration, maintenance and troubleshooting.

Can HostGraber design a custom monitoring solution?

Yes. Monitoring can be designed around infrastructure type, required metrics, thresholds, alerts and operational workflows.

Can monitoring be combined with server management?

Yes. Monitoring can be paired with server or network management, so alerts are followed by operational response.
