Network monitoring is the process of continuously tracking a computer network’s health, availability, performance, and connected infrastructure. It helps IT teams detect outages, slowdowns, device failures, traffic issues, and service problems before they create major disruption. According to IBM, network monitoring uses monitoring software to observe a network’s ongoing health and reliability. Cisco adds that network monitoring provides administrators with real-time visibility into network performance, helping them determine whether systems are running optimally and identify issues that may affect reliability and service quality.
For businesses, schools, MSPs, and internal IT teams, network monitoring is not just about knowing whether the internet is working. It helps teams understand how network infrastructure is performing, which systems are reachable, where traffic issues may exist, and when action is needed.
Network monitoring is the ongoing observation of network devices, connections, traffic, and services to confirm that the network is available and performing as expected.
It commonly includes monitoring:
The main goal is visibility. Network monitoring gives IT teams a clearer view of what is happening across the network so they can detect issues earlier and troubleshoot more effectively.
Cisco describes network monitoring as a way for administrators to identify deficiencies in real time and improve network efficiency.
Modern organizations depend on networks for nearly every business function.
A network issue can affect:
Without monitoring, IT teams may only learn about problems after users complain. That creates a reactive support model where technicians are always responding after the disruption has already affected productivity.
Network monitoring helps organizations:
This is why network monitoring is often used alongside remote device monitoring and endpoint visibility. Network data shows whether infrastructure is healthy, while endpoint data shows how connected devices are behaving.
Network monitoring tools collect data from network infrastructure, analyze that data, and alert IT teams when something needs attention.
The process usually includes several steps.
Monitoring systems gather information from devices and services.
This may include:
Different tools collect this data in different ways. Common methods include SNMP, flow data, logs, agents, and availability checks.
After collecting data, monitoring systems analyze network behavior.
They may compare current values against thresholds or baselines.
For example, a monitoring tool may flag:
AWS describes network monitoring in cloud environments as a way to detect and diagnose connectivity issues through automated visualization and network performance monitoring. (Amazon Web Services, Inc.)
When a problem appears, the monitoring system sends an alert.
Alerts may notify IT teams about:
Good alerts should be actionable. A useful monitoring setup does not simply create noise. It helps teams understand what happened, where it happened, and what may need attention.
Once an alert appears, IT teams investigate the root cause.
They may check:
This is where network monitoring supports faster troubleshooting. Instead of starting from zero, technicians have data that points them toward the likely issue.
Network monitoring can track many different signals depending on the environment and tools used.
Availability monitoring checks whether network devices and services are reachable.
This includes:
Availability monitoring helps teams detect outages quickly.
Performance monitoring looks at how well the network is operating.
Important metrics include:
AWS Network Flow Monitor, for example, provides visibility into packet loss and latency for cloud network traffic.
Bandwidth monitoring helps teams understand how network capacity is being used.
This can help identify:
Infrastructure devices also have health metrics.
Network monitoring may track:
This helps IT teams identify hardware or resource issues before they cause bigger problems.
Network monitoring may include services such as DNS and DHCP because these services affect connectivity.
For example, if DHCP fails, devices may not receive valid IP addresses. If DNS fails, users may be connected to the network but unable to reach websites or applications by name.
Network monitoring uses several methods to collect and evaluate network data.
SNMP, or Simple Network Management Protocol, is commonly used to monitor infrastructure devices such as routers, switches, and printers.
It allows monitoring tools to collect performance and status data from supported devices.
Ping monitoring checks whether a device responds over the network.
It is simple but useful for basic reachability monitoring.
Flow monitoring analyzes traffic movement across a network.
It helps teams understand where traffic is coming from, where it is going, and how much bandwidth it uses.
Logs provide details about events, errors, configuration changes, and security-related activity.
Log monitoring helps teams investigate incidents and correlate issues across systems.
Some systems use software agents to collect more detailed data.
AWS notes that its Network Flow Monitor uses lightweight software agents on instances to gather performance statistics from TCP connections.
Network monitoring and network security monitoring are related, but they are not the same.
Network monitoring focuses mainly on:
Network security monitoring focuses more on:
The two areas overlap. For example, unusual traffic spikes may be a performance issue, a misconfiguration, or a security concern. However, standard network monitoring should not be treated as a complete cybersecurity program by itself.
A more accurate way to describe the relationship is this: network monitoring supports security by improving visibility, but security monitoring adds deeper threat detection and response capabilities.
Network monitoring is valuable, but it needs to be configured carefully.
Too many alerts can overwhelm IT teams.
If every minor change creates a notification, important issues may be missed.
Some devices may not be monitored, especially in distributed environments.
This can create blind spots.
Organizations may use separate tools for infrastructure, endpoints, logs, cloud systems, and security.
Disconnected tools can make troubleshooting slower.
Modern networks often include cloud services, VPNs, remote users, and multiple locations.
This makes monitoring more complex than simply checking office switches and routers.
IBM notes that modern network environments can span LAN, WAN, cloud, and on-premises systems, increasing the need for centralized visibility and performance monitoring.
Network monitoring works best when it is planned around business impact and operational priorities.
Start with systems that affect the most users or the most important services.
Examples include:
Alerts should help teams take action.
Good alerts are specific, prioritized, and tied to meaningful thresholds.
Performance trends help teams identify recurring problems and capacity needs.
This can support better planning and reduce emergency fixes.
Network monitoring shows infrastructure health.
Endpoint management shows device health.
Combining both gives IT teams better context when troubleshooting problems that affect users.
Network monitoring is often strongest when paired with endpoint and device visibility.
Level helps IT teams and MSPs monitor endpoints, receive alerts, access devices remotely, and automate common IT actions from a centralized platform. While dedicated network monitoring tools may be used for routers, switches, firewalls, and traffic analysis, Level can help teams understand how network issues affect endpoints and distributed devices.
For IT teams managing remote users, multiple sites, or growing device fleets, this visibility can support faster troubleshooting and more practical day-to-day operations.
Network monitoring is the process of tracking network health, performance, availability, and connected infrastructure to detect issues and maintain reliability.
Network monitoring helps IT teams detect outages, troubleshoot faster, monitor performance, and reduce avoidable downtime.
It can track device availability, bandwidth usage, latency, packet loss, interface errors, traffic patterns, and service health.
No. Network monitoring focuses mainly on performance and availability. Network security monitoring focuses on detecting threats and suspicious activity. They overlap, but they are not identical.
Common methods include SNMP monitoring, ping checks, flow monitoring, log monitoring, and agent-based monitoring.
Network monitoring is the continuous tracking of network availability, performance, traffic, and infrastructure health. It helps IT teams detect problems earlier, troubleshoot faster, and maintain reliable connectivity across business environments.
For modern organizations, network monitoring works best when combined with endpoint visibility, service monitoring, and clear alerting practices that help teams act on issues before they become major disruptions.
