Network monitoring is detecting and diagnosing issues that interfere with your business's ability to transmit and receive data and helping reduce IT costs by highlighting inefficient traffic patterns.
What is Network Monitoring?
Network monitoring refers to tools and techniques designed to assist IT teams with tracking performance, detecting outages, and responding quickly to unanticipated problems. Network monitoring involves using software on devices like routers, switches, and servers to check for slow or failing components that could halt traffic flow.
Most network monitoring tools work by continuously scanning for slow or failed components that impede traffic, alerting administrators if these conditions are met, and helping IT teams address them to keep business operations running smoothly.
Some tools also enable administrators to view how things have evolved EDR, providing an opportunity to identify trends that indicate the need for an upgrade in technology. This reduces manual work for IT teams, freeing them up for other vital projects.
Modern enterprises depend on various internet-dependent, business-critical services for everyday operations. These include cloud service providers, ISPs, CDNs, SaaS platforms, UCaaS platforms, and VPNs - each potentially subject to performance fluctuations that could negatively affect employees and customers. Network visibility tools help administrators monitor these externally hosted applications as they communicate with on-prem systems and data centers - helping IT teams meet SLAs and customer expectations while complying with industry regulations such as GDPR compliance - this requires in-depth knowledge of protocols underlying each system's inner workings.
How to perform network monitoring effectively
Network monitoring enables companies to detect issues before they impact users, saving money and enhancing customer experiences. Monitoring tools allow engineers to see where packet loss is happening - often the source of website latency- and identify overused resources or security risks, such as employees visiting prohibited websites or exfiltrating sensitive data.
Effective monitoring tools require having the appropriate tools and methodologies in place. Various means are available for network monitoring, from open source solutions such as Zabbix to SaaS solutions like Datadog; each allows you to monitor network devices like routers, switches, firewalls, etc., and detect issues like device failure or software bugs that cause performance degradation.
Another method for monitoring networks is using a network traffic analyzer, which provides detailed reports on their health. This type of device can be beneficial in troubleshooting complex issues like network congestion or slow application response times, as well as highlighting data packets that move slowly or are nonexistent, helping pinpoint where problems lie, be it an outdated firewall or server being overburdened with data.
Monitoring essential network devices
Monitoring tools examine data packets moving across your network to detect whether they are being appropriately routed, whether employees are accessing prohibited websites, and whether sensitive information such as Social Security numbers are being exfiltrated from the company. Furthermore, these systems can detect malware infections and alert administrators immediately if there is a security breach.
Network performance monitoring primarily monitors how quickly or slowly your traffic moves in your system; network device monitoring looks for specific devices that are slowing things down - such as switches, routers, and firewalls - while these systems can detect issues between these devices or with internet connections or physical connectivity issues between them.
Monitoring systems help IT teams streamline manual work and free up more time for more strategic initiatives by offering hardware and software tools that simplify manual processes for them to focus on strategic projects. These tools continuously monitor server disk space usage, RAM usage, CPU utilization, FLEXlm license usage (a software license manager tool), server air temperature, connection latencies, NetFlow traffic volumes, and more.
Network device monitoring utilizes the Simple Network Management Protocol (SNMP) to query switch and router devices for status reports, which are then translated to display live device data on the screen. These systems can detect new devices automatically and create an IT asset inventory and network topology map for you. They also allow packet transfers hop-by-hop tracking to identify performance issues more efficiently.
What are protocols for network monitoring?
Monitoring protocols enable administrators to assess their IT infrastructure from a single view and quickly identify issues. A robust monitoring solution like WhatsUp Gold will locate all your devices - routers, switches, servers, and printers alike - then determine how these are connected and assign each one a device role, such as interface performance monitoring or storage space availability monitoring, etc.
SNMP (Simple Network Management Protocol) is an established protocol for network monitoring that facilitates information exchange among network elements like switches, routers, and firewalls. Most components come equipped with an SNMP agent, which communicates directly with an SNMP-based network monitoring tool and can ping various system ports to determine whether a device is online and functioning as intended.
Network tomography provides end-to-end link performance monitoring using an advanced technique. This approach gives a detailed picture of network traffic flow, making it possible to pinpoint bottlenecks and other factors contributing to poor performance, enabling early remediation when performance starts deteriorating and saving costs by ensuring IT infrastructure operates at peak performance and preventing costly outages and downtime.
Key benefits of network monitoring
As more services move to the cloud, IT teams must simultaneously manage various responsibilities. Monitoring tools provide administrators with devices to assess data from multiple locations to detect performance issues that could disrupt services.
Network visibility systems that offer a unified dashboard give IT teams a comprehensive view of both environments.
By tracking network equipment through protocols like ICMP ping and Simple Network Management Protocol (SNMP), network monitoring enables IT departments to detect when devices stop communicating effectively or have been compromised by malware, thus shortening resolution times and freeing resources to invest in projects that will add bottom-line value for the company.
Monitoring can provide invaluable visibility into services outside the firewall, such as SaaS, CDNs, UCaaS providers, and VPN providers - giving administrators visibility into third-party providers such as SaaS, CDNs, UCaaS VPN providers, or SECaaS providers. These services operate over the internet, so their performance can fluctuate due to issues like internet outages or routing problems. By integrating network monitoring with these third-party tools, companies can guarantee their employees and customers have consistent access to essential business services. Visibility into these external services can also assist companies in preventing service blackouts caused by unexpected events or natural disasters. By setting up network monitoring to compare performance standards against historical data, administrators can quickly spot suspicious activity that could indicate security threats are imminent.
Types of network monitoring protocols
Network monitoring tools use various methodologies and protocols to examine data from multiple network layers. They can monitor uptime/downtime rates, bandwidth utilization levels, and the status of network devices while also reviewing their routing posture to detect any performance or security threats to their routing position.
Some network devices come equipped with support for the Simple Network Management Protocol (SNMP), allowing them to send network status information directly to monitoring systems for admins' analysis and creating reports that they can view later. These reporting mechanisms help reduce time spent by team members on monitoring activities.
These reports not only give visibility into the overall health of a network but can also alert the team when devices experience issues - helping prevent critical business processes and customers from being negatively impacted by problems that require rapid identification and resolution by the team.
Ping testing is another type of network monitoring used to test device availability. It involves sending requests to servers and recording how long it takes them to respond with responses; this method can help identify problems with individual devices or entire subnetworks. These tools typically feature within software-as-a-service (SaaS) monitoring products that offer comprehensive solutions for network management.
