What Is Network and Server Monitoring?

Network and server monitoring is the process of continuously tracking the health, availability, and performance of the devices, systems, services, and applications that keep an organization running.

Network monitoring focuses on the infrastructure that connects users, devices, and applications, such as routers, switches, firewalls, access points, and network traffic. Server monitoring focuses on the machines and systems that host business-critical services, applications, databases, websites, files, and workloads.

Together, they give IT teams a clear view of what is happening across the environment so they can identify issues early, troubleshoot faster, and reduce the risk of downtime.

Network and server monitoring tools, like Intermapper, is software that provides visibility into device health and traffic patterns, while also maintaining a proactive inventory of devices with status and performance metrics that help prevent outages and downtime.

What is Network Monitoring?

Network monitoring is the practice of observing and measuring the performance, availability, and health of a computer network. It helps IT teams understand whether connected devices are online, how traffic is moving, where slowdowns are occurring, and whether network components are performing as expected.

A network monitoring tool can track physical and virtual infrastructure, including routers, switches, servers, applications, and other IP-connected devices. Network monitoring tools help organizations see every physical and virtual device, application, and system running on the network, making management faster and more effective as the environment grows.

Common Network Monitoring Targets:

• Routers
• Switches
• Firewalls
• Wireless access points
• Servers
• Applications
• Network-connected devices
• Cloud or hybrid infrastructure
• Traffic patterns
• Bandwidth usage
• Device status
• Latency, errors, and packet loss

The goal is simple: keep the network available, reliable, and performing well for users, customers, and business operations.

What is Server Monitoring?

Server monitoring is the process of tracking the health, performance, and availability of servers and the services they support. It helps IT teams confirm that servers are running properly, resources are not overloaded, and business-critical applications remain available.

Server monitoring may include physical servers, virtual servers, cloud servers, Linux servers, Windows servers, AIX servers, application servers, database servers, email servers, file servers, and web servers.

Intermapper's server monitoring tools monitor across network servers, services, applications, and devices for 24/7 availability, with real-time messages and alerts available through a centralized console.

Common Server Monitoring Metrics:

• CPU usage
• Memory usage
• Disk space
• System uptime
• Server load
• File systems
• Log files
• Running services
• Application availability
• Database availability
• Web server performance
• Email server availability
• Error reports
• Alerts and event messages

Server monitoring helps IT teams detect problems such as overloaded resources, failing services, full disks, application errors, or unexpected downtime before they disrupt users.

Network Monitoring vs. Server Monitoring: What's the Difference?

Network monitoring and server monitoring are closely related, but they focus on different parts of IT infrastructure. But they can oftentimes be accomplished with just one solution, like Intermapper which includes both network and server monitoring capabilities.

Network monitoring looks at the paths, devices, and traffic that connect systems together. It answers questions like:

• Is the network online?
• Are routers and switches healthy?
• Is traffic flowing normally?
• Are there bandwidth bottlenecks?
• Which device is causing an outage?
• Are users able to connect to applications?

Server monitoring looks at the systems that run applications and services. It answers questions like:

• Is the server online?
• Is CPU or memory usage too high?
• Is disk space running out?
• Are critical services running?
• Are logs showing errors?
• Are applications and databases available?

In practice, IT teams need both. A slow application could be caused by a server resource issue, a network traffic issue, a failed switch, a DNS problem, or a connectivity bottleneck. Monitoring both the network and the servers gives teams the visibility they need to find the real cause faster.

How Does Network and Server Monitoring Work?

Network and server monitoring tools collect performance and availability data from devices, systems, services, and applications. That data is then displayed in dashboards, maps, alerts, reports, or centralized consoles.

Network monitoring can be agentless, using protocols already installed on servers, applications, and hardware, or agent-based, requiring agents on the items being monitored.

Typical Network and Server Monitoring Features

SNMP Monitoring

SNMP, or Simple Network Management Protocol, is commonly used to collect information from network devices. SNMP can provide details about device activity, including bytes, packets, errors, router traffic, connection speed, and web server hits.

Network Probes

A network probe checks devices and returns specific information about their status or performance. Intermapper probes are a way for IT and network administrators to monitor performance in real time.

Network Mapping

Network mapping creates a visual diagram of devices and infrastructure connected to the network. This helps teams see relationships between systems and locate problems faster.

Real-Time Alerts

Network and server monitoring tools can notify IT teams when a device, server, service, or application crosses a threshold or goes offline. Intermapper's alerts are a way to spot issues before they get worse.

Centralized Visibility

A centralized view helps IT teams monitor multiple systems, platforms, alerts, and devices in one place. Intermapper provides centralized monitoring for network servers, services, applications, and devices, including real-time messages and alerts.

Why Is Network and Server Monitoring Important?

Network and server monitoring is important because modern organizations depend on connected systems to operate. When a router fails, a server runs out of disk space, an application stops responding, or a switch becomes overloaded, users and customers can feel the impact quickly.

Monitoring helps IT teams move from reactive troubleshooting to proactive problem-solving.

Instead of waiting for users to report slow systems or outages, IT teams can receive alerts, check live maps, review performance metrics, and investigate issues before they become widespread.

As networks grow, manual management becomes impossible because optimal performance requires 24/7 monitoring. Network monitoring applications make the process faster, easier, and more effective by showing devices, applications, and systems across the network.

Benefits of Network and Server Monitoring

1. Reduced Downtime
   Monitoring helps teams detect outages, failing devices, overloaded systems, and service issues early. This can reduce downtime and help keep users connected.
2. Faster Troubleshooting
   Live maps, performance dashboards, and alerts help IT teams identify where a problem is happening. Network visibility helps teams identify culprit devices, such as an overloaded switch or failed router.
3. Better Performance Visibility
   Network and server monitoring helps teams understand what is happening now, not hours later. Real-time network monitoring provides fast, frequent, reliable polling that can occur in as little as 30 seconds.
4. Proactive Alerts
   Alerts notify IT teams when performance thresholds are crossed or systems become unavailable. This helps teams respond before problems affect more users.
5. Improved Capacity Planning
   Monitoring historical performance can help teams understand growth trends, bandwidth usage, server resource consumption, and future infrastructure needs.
6. Centralized IT Management
   A single monitoring platform can help teams track servers, applications, services, devices, and SNMP-enabled infrastructure from one place. Intermapper provides centralized visibility into real-time performance, advanced monitoring of servers, applications, and services, SNMP device monitoring, and alerts by email or SMS.
7. Support for Hybrid Environments
   Many organizations now operate across physical, virtual, cloud, and distributed environments. Monitoring helps IT teams maintain visibility across these hybrid infrastructures.

That includes:

• Small and midsize businesses
• Enterprises
• Schools and universities
• Government agencies
• Healthcare organizations
• Manufacturers
• Telecommunications providers
