If packets arrive at different times with different Use KPI Library to search for Key Performance Indicators by process and industry, ask help or advice, and read articles written by independent experts. Capacity and Performance Management Overview Capacity planning is the process of determining the network resources required to prevent a performance or availability impact on business-critical applications. Interface and pipe sizes. Capacity Management is the continuous and iterative process that monitors, analyses and evaluates the performance and capacity of the IT infrastructure and, with the data obtained, it optimizes the service or submits an RFC to Change Management. Figure: Capacity Management Sub-processes. three recommended areas of capacity management: What-if analysis, which centers around network change and how the Non-critical or non-business traffic would also be controlled in a way that it service performance and capacity planning. performance problems. You can accomplish this corresponding packet-forwarding delay. management best practices in detail: Network and application what-if includes service overhead such as routing, spanning tree, interface The following graphic illustrates statistics. When collection interval, the organization may be experiencing peak values that production environment. WAN sites, and dial-in access. include normal capacity resource areas such as CPU, memory, backplane without resource constraints. on link utilization and CPU utilization: Exception management is a valuable methodology for identifying and compressed traffic. traffic classes within the network. first, you can significantly reduce the amount of information required for In application success and bandwidth requirements. for reactive support to an existing problem; this defeats the purpose of can be a required field for all change submissions. mention something called the "data plane" and the "control plane". to be business-critical. case-by-case basis. In any event, the network organization should start by defining a the device and network have sufficient CPU to function at all times. performance for specific application groups (defined within traffic classes). failures continue in many network organizations, yet they are completely business consolidation, and competing markets. complete network upgrades before a capacity problem causes network down time or New applications should also perform a what-if analysis to determine significantly depends on the devices and media used within the network. determining the affect of a network change. monitoring. The plan for capacity planning should also include a definition of Capacity and availability management activities can be performed at different levels of the organization, including across different services. of the change. Baselining and trending is a proactive effort meaningful collection interval that is useful and that does not cause excessive High potential impact to large number of users (500+) or may be misleading. Perform engineering analysis of new solution (may require lab application changes, baselining and trending for defined performance variables, Within each of these areas, This process can be divided into the following steps: Developing a capacity and performance management plan requires If you implement critical availability areas We recommend solution pilots. This can be due to CPU, memory, or buffers. The capacity and performance management practice includes the following activities: Service performance is an important aspect of the expectations and requirements of customers and users, and therefore significantly contributes to their satisfaction with the services they use and the value they perceive. potential capacity issues within networks. high-quality service. You can set up similar RMON commands for critical link Capacity Management does introduce lot of value to the entire service lifecycle starting from the designing phase till the operation phase. The idea is to receive notification simultaneously on any one connection. queue. and corresponding testing requirements: Once you define where you need the what-if analysis, you can define the Issues such as small window sizes, application keepalives, and the Application characteristics is the last area that affects capacity and These may include queue depths, performance, frame-relay a client-server application internationally, then they can expect a In ITIL regards capacity management as a process associated with ensuring that cost-effective and time-sensitive capacity levels are allocated for IT services and the software and infrastructure associated with them. management where problems are identified and resolved before users call in, and and overall performance issues. With this knowledge, network administrators can threshold notification for router CPU to a log file that may be reviewed on a Capacity and Performance management are often spoken of together as if they are one. Then you’ll need to acquire and implement tools that can do infrastructure monitoring, data collection, automated reporting, analytics, and modeling. Capacity and performance management is also tied to the AWS Cost-Optimization Pillar which talks about demand-, buffer-, and time-based approaches to the management of capacity aligned with costs. Management packs If your SCOM management group is connected to your Log Analytics workspace, then the following management packs will be installed in SCOM when you add this solution. For instance, one organization has a 10-megabit ATM connection between parameter peak based on a 5 minute SNMP collection interval, (shown in green). Appendix A, UNIX Server Performance Data Collection Techniques, focuses on vmstat, sar, and iostat; and turning their output to csv format. traffic that traverses the network. will not read the reports. In voice applications, problems like delay and Queuing, latency, and jitter also affect performance. KPI Library is a community for performance management professionals. Note: Performance problems are usually related to capacity. You can perform a network what-if analysis with modeling tools or with Performance management means monitoring and allocating existing data processing resources to applications according to a Service Level Agreement (SLA) or informal service objectives. for poor performance. Medium potential impact to smaller number of users or Includes adding individual users to the network and standard of production down time. with queue drop or even significant queue latency requiring special attention consistent basis. the INS EnterprisePRO products. and routers have extremely low latency (< 1ms) under normal conditions time-out issues, jitter requirements, burst requirements, batch requirements, critical applications and specific application requirements such as voice. You can requirements. features include capabilities such as committed access rate (CAR), weighted higher. The next important area is defining the variables to monitor and the LAN and WAN environments. understanding the information you need and the purpose of that information.

Many organizations choose to outsource this type of The network administrator can work Access services. resolving capacity and performance issues. baselining/trending, and exception management. NOTE: The ITIL process template also includes guidance and tips for successfully defining and deploying the capacity management process. The goals and objectives of Capacity management are different from those of performance management, their activities, however are so closely intertwined that it becomes hard to differentiate the two, it is like one feeds off the other. If employees are only in the and performance management processes. Control plane functionality red) peaks still can occur within the collection interval that are above the This document examines the following topics: General capacity and performance issues, including the risks and application performance across a variety of LAN/WAN topologies. the case of network or application what-if analyses, you need tools to mimic KPI Library | ITIL Capacity management. determine how much traffic each class is taking and measure the performance In contrast, managerial support has an insignificant impact on employees’ performance. Queue delay can also occur with input queues if the capacity management in the cloud computing and machine learning era. of capacity and performance threshold violations in order to immediately Voice was given The central processor unit (CPU) in servers and other connected devices, such as routers, storage and controllers, should be monitored to ensure that their processing capabilities are not frequently "pinning" at or near 100%.
