Some solutions also perform active monitoring, for example, sending a ping or performing a TCP request to test how a server or network service responds. Network monitoring solutions can perform passive monitoring such as listening on ports and reporting on traffic. External service providers - including web hosting, cloud services, SaaS applications, messaging servicesįor servers or other devices on the network, network monitoring typically watches availability, CPU and memory utilization, disk usage, and configuration.Ī network monitor works with protocols like HTTP, HTTPS, SNMP, FTP, SMTP, POP3, IMAP, DNS, SSH, TELNET, SSL, TCP, ICMP, SIP, UDP, and Media Streaming.Mission critical servers - web server monitoring, email servers, application servers, FTP servers, storage systems.Links and connections between network elements, including network interfaces.Network devices - including routers, switches, appliances, gateways and proxies.Network monitor tools cover some or all of the following network elements: When a problem already occurs - helps to identify the root cause and resolve it.Identifying critical issues - which can cause network slowdown or failure, before they result in a problem.Governing networks - prevents unwanted or unauthorized changes, including misconfigurations, shadow IT, and possible security threats by insiders or outside attackers.Understanding a network’s baseline statistics - helps administrators notice and respond to abnormal behavior.In other words, administrators use network monitoring tools to ensure critical systems in the network are available and functioning properly.Ĭonsistent network monitoring and analysis is important for: Administrators typically monitor availability of network services, functionality of network interfaces, status of critical hardware systems, CPU, memory, or other statistics for servers and devices on a network. Network monitoring is a tool used to identify and send out alerts regarding issues affecting the availability or functionality of network services.
