![]() Faster analysis can also mean fewer performance issues affecting your end users.ĭiscover root causes more quickly. Prove your network’s mean-time-to-innocence (MTTI) quickly, so you can contact your ISP when needed. Use packet path information beyond what manual tools can provide. ![]() View the performance, traffic, and configuration details of devices and applications whether they’re on-premises, in the cloud, or hybrid environments. Visibility into these metrics can improve both proactive and in-the-moment network performance troubleshooting. Look for user-friendly fault monitoring, performance analysis, availability monitoring, cross-stack network data correlation, and hop-by-hop network path analysis. ![]() The right network monitoring software can make all the difference for your organization by allowing you to perform the following tasks, each of which is critical to ensuring overall business productivity. The high cost of network failure-or even momentary downtime-means a proactive, comprehensive, and professional network monitoring solution can be well worth the investment. Network outages can cause severe losses for businesses, as it affects both day-to-day internal operations and external functions like websites and sales. Network monitoring software is critical for ensuring network performance and health, which in turn supports overall business functionality, productivity, and security. Why is network monitoring software important? Ultimately, the point of these capabilities is to optimize network performance and maintain availability across your network while avoiding fault, downtime, or any connectivity issue that could impact your business. ![]() When alerts are sent in real time by email, SMS, or another platform, you’re better able resolve both minor issues like momentary bottlenecks and major issues like server crashes with limited service disruption. Network monitors should also include custom alerting capabilities to enable you to set required thresholds for alerts. Ideally, the dashboard will prioritize action items in need of your attention. Your network monitoring system should include a dashboard displaying metrics in an intuitive fashion by providing an at-a-glance view of your network status. Network monitoring software supports proactive visibility and troubleshooting. Be sure to look for a network monitoring solution with easy access to real-time or near-real-time performance data, as well as a historical baselines to help put current network measurements in context. For instance, key metrics for measuring traffic include latency, packet errors, TCP retransmits, and packet metadata. It’s important for a network monitor to offer admins insight into measurements indicative of the health and performance of network components. Network monitoring solutions capture metrics at specific intervals. For instance, an SNMP agent is typically built into network elements, so admins can allow SNMP read-write access to control and reconfigure devices through the network monitoring system. This integration or data connection can occur through a number of protocols like packet sniffing, APIs, Simple Network Management Protocol (SNMP), Internet Control Message Protocol (ICMP), and Windows Management Instrumentation (WMI). Network monitoring software is built to integrate with various devices and services, including routers, servers, firewalls, switches, and virtual machines. Network monitoring software integrates with your network components. Some firewalls allow selective configuration of UDP or TCP ports with the same number, so it's important to know the type of port you're configuring. If your firewall doesn't allow you to specify the type of port, configuring one type of port probably configures the other.Network monitoring software consists of features and tools to detect, diagnose, and resolve network performance issues by scanning network devices for fault and availability. When you find a product in this list, search (Command-F) in your browser for that name, then repeat your search (Command-G) to locate all occurrences of that product. For example, a VPN service can use up to four different ports. Some services might use more than one of these ports. Some software might use different ports and services, so it can be helpful to use port-watching software when deciding how to set up firewalls or similar access-control schemes. This guide is updated periodically with information available at the time of publication. For hosts and ports specific to enterprise networks, learn about using Apple products on enterprise networks. This is a quick-reference guide showing common examples, not a comprehensive list of ports.
