As software solutions incorporate disruptive technologies, applications become more complex and distributed. It is essential to monitor application performance to ensure end-users are satisfied with their experience.
Application Performance Management (APM) is critical in guaranteeing optimal service delivery to customers and identifying issues impacting application performance. Categories like load time and application response time monitor application performance. APM maintains defined service levels and promptly resolves performance-related issues for customers.
Inadequate network performance, causing slow or unavailable access to applications, is often due to recent configuration changes, resource scarcity, offline switch ports, bandwidth bottlenecks, or ISP WAN link issues. Managing networks and applications separately create silos of data and requires significant manual effort to correlate and understand issues, resulting in errors and delays. A more effective approach is to adopt network performance monitoring practices that integrate application data with network data to quickly identify and resolve issues, ensuring continuous access to critical applications and an optimal user experience.

The Role of Application Performance Monitoring in Delivering Perfect Digital Experiences
Application performance management (APM) tools are critical in monitoring the transaction speeds of end-users, systems, and network infrastructure. By detecting bottlenecks and potential service interruptions, APM enables system administrators to identify and diagnose the root cause of performance problems more efficiently. This, in turn, helps ensure a consistent service level, promoting an optimal user experience.
Adopting an integrated APM solution offers a holistic perspective on the performance metrics of business-critical applications. APM tools furnish real-time alerts for performance issues and generate comprehensive reports with data for performance analysis, enabling IT teams to repair, enhance, or upgrade application software as necessary.
APM tools comprise monitoring solutions that track various performance metrics related to two fundamental aspects: the performance perceived by users, which encompasses load and response times during peak usage, and the capacity of computational resources, which serves to establish a performance baseline and identify potential bottleneck locations.

Why Is the Correlation Between Application and Network Performance Data Important for Identifying the Root Cause Of Faults?
The key to delivering a seamless application lies in identifying any potential faults. The faster these faults are identified, the sooner they can be addressed. However, when using disparate tools, the performance of networks and applications may only be evaluated in isolation, lacking any correlation between them. As a result, analyzing various reports manually can become a cumbersome and time-consuming process, requiring considerable effort to pinpoint the source of a fault.
Application-aware Network Performance Management is a comprehensive approach to monitoring applications from a network perspective, offering a correlated view of application and network performance data. This powerful solution provides valuable insights into the impact of applications on your network and the reverse, helping you to identify precisely where a fault may lie. Its in-depth visibility into application and network performance allow for quick and efficient fault diagnosis, facilitating the prompt resolution of any issues.

Network performance monitoring is an essential process within the realm of IT, providing administrators with the tools necessary to optimize network performance. This is particularly important in organizations that have strict reliability requirements or operate within complex network architectures. By monitoring networking components such as servers, routers, switches, and virtual machines (VMs) for performance, IT professionals gain valuable insights into how their network is functioning and can take action to ensure that it continues to meet the demands of their organization.
Network monitoring is a critical process that enhances network visibility both on-premises and across SaaS deployments. By evaluating how the network affects application performance, IT teams can gain a deeper understanding of performance and the interdependencies between application and network topology. This, in turn, can lead to a reduction in MTTR by facilitating collaboration between application and network teams. In instances where bottlenecks exist within the network, user experience can be negatively impacted. This underscores the importance of considering the user experience in network performance monitoring. By monitoring the network for bottlenecks and ensuring better throughput, IT professionals can work to provide an optimal user experience.
What Are the Key Metrics That SREs Should Consider for Monitoring Network Performance?
When monitoring the performance of a network, it is crucial to keep track of certain metrics. These metrics include errors, bandwidth, throughput, and latency.
Here's a brief explanation of each:
- Errors: This metric refers to the error percentage that is received due to network issues, such as packet loss. Packet losses occur when sent packets don't reach their destination. Measuring errors can help identify potential network issues and take corrective actions.
- Bandwidth: It measures the maximum amount of data that a network can transfer within a specific time period, usually measured in bits/second. Bandwidth measures the network's capacity and does not directly relate to the network's speed.
- Throughput: It measures the number of units of information a system can process within a specified time period. Throughput affects the network's speed and determines the system's response time.
- Latency: It measures the time it takes for a data packet to travel from one point to another in the network. Latency is also known as delay; a low latency measurement is ideal. High latency can cause delays in the transmission of data and result in poor network performance.

What Is the Ideal Process for Network Performance Monitoring That Developers Should Follow?
The process of monitoring network performance involves gathering data from various sources. This is done by monitoring flow data, Simple Network Management Protocol (SNMP), and packet capture.
- Flow data: Generated by network devices, this data provides information on device communication, duration and frequency of communication, and amount of data transferred.
- SNMP: A widely used protocol that monitors and manages network device functions, such as routers or printers, enabling real-time monitoring of network changes or status.
- Packet capture: Aids monitoring network health, application performance, security, incident response, troubleshooting, and network capacity planning. Captures packets at a specific point in the network, storing them for analysis.
A network performance monitoring tool often includes a customizable dashboard with visualization and reporting capabilities. This tool should be able to collect and display packet capture, SNMP support, and flow data for analysis. The tool should enable users to swiftly isolate and examine the problem if issues arise. This feature can help detect and address network issues more efficiently, allowing users to maintain the health and integrity of the network.
Network performance monitoring can be utilized either on-premises, from the cloud, or in a hybrid manner that combines the two. This flexibility in deployment options allows users to select the most suitable method for their specific needs, enabling them to monitor network performance effectively regardless of their setup.
