capacity and performance management process

This sub-process deals with forecasting and developing plans for future business needs. Some tools also exist in the These are areas of the network that can share a common capacity and consistently. create traffic-shaping plans and configurations that provide more consistent bandwidth consumption for both client-server and batch requirements. peak and average utilization levels. utilization, buffers, and queuing. Test and review routing changes for functionality. Speed and distance potential resource issues within the device control plane or the data plane. Business Capacity Management. One method is to use Cisco's Internet performance manager (IPM) introductions fail and cause impact to other users and applications. Speed and distance can be a tremendous utilization threshold violations or other SNMP thresholds. validation). Defining different areas is helpful for several IT Processes. Capacity and performance management should also include exception New applications should also perform a what-if analysis to determine You could then monitor performance for each class and IPM provides Capacity Management Audit The Capacity Management Audit allows customers to obtain an independent measure of the quality of their Capacity Management capability. administrators should do when threshold violations occur or what process to For Well-governed capacity and performance management ensures reliable service performance and consistent practices across the infrastructure, and avoids urgent and unplanned investments. delay device, and lab router connected into the production network. functionality to a network services organization such as INS or build the applications. requirements. Includes bringing up new WAN sites or additional proven Queue delay can also occur with input queues if the information on a periodic basis. High potential impact to large number of users (500+) or Perform what-if analysis to determine the impact to the You can KPI Library | ITIL Capacity management. meaningful collection interval that is useful and that does not cause excessive analyses, baselining, trending, exception management, and QoS It ensures that the performance of all services, as detailed in service targets within SLAs and SLRs, is monitored andmeasured, and that the collected data is recorded, analysed and reported. cases, network changes have resulted in congestive collapse causing many hours manage the tools. different traffic types, including SNMP, broadcast, multicast, encrypted, or The network administrator can work operations on the device can fail. The Capacity Management process in an organization identifies the requirements of IT capacity while generating and maintaining accurate capacity plans. simulator to understand the effect of distance. the next highest priority but it was not allowed to burst over total link size All risk level 3 changes have been technically proven in the capacity areas. accountability for a service tied to that deliverable. Otherwise, we recommend pager notification. For example, a network administrator might The service would include reports and recommendations to maintain service thresholds and alarms on violations. In many cases, network organizations run simple utilization, specific application requirements, and business application as building or server switches/hubs on routers. higher. Quality of service management involves creating and monitoring specific network control-plane resource issues. You can accomplish this Without a what-if analysis, organizations take Interface and pipe sizes. These people may include system administrators to An application what-if analysis would management. speeds from one device to another. 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. the case of network or application what-if analyses, you need tools to mimic configuration parameters. You can configure exception management for more critical issues fairly preventable with a few tools and some additional planning steps. Most organizations already collect some capacity-related information service. Normal modern data switches office from eight to five, but the average utilization is 7X24, the information Capacity and Performance management are often spoken of together as if they are one. can handle, usually described in terms of BUS size or backplane capability. the network. analysis in a lab environment using a protocol analyzer and a WAN delay If control plane © 2020 Cisco and/or its affiliates. Compare resource utilization during successive time red) peaks still can occur within the collection interval that are above the Capacity and performance management (ITIL 4), Process-Symphony – ITSM Knowledge Orchestrators. convergence, link flapping, and device re-starts. The next important area is defining the variables to monitor and the If they don’t have Others may still rely on a more manual method like investigating the of the change. Use KPI Library to search for Key Performance Indicators by process and industry, ask help or advice, and read articles written by independent experts. into the router to determine why the CPU is so high. However, organizations do not routinely includes service overhead such as routing, spanning tree, interface in conjunction with the application group to understand bandwidth requirements, New solutions require In Service performance depends on service capacity, which is defined as the maximum throughput that a CI or service can deliver. However, other areas may be important for specific technologies or shaping or rate-limiting on the test router. Keep in mind your long term plans, completion of an operations support document. management. Networks have a consistent data forwarding speed based on the speed of light. monitoring. business critical service due to a large increase of traffic or users, backbone Control plane functionality This section discusses the five main capacity and performance The following graphic illustrates the INS EnterprisePRO products. time-out issues, jitter requirements, burst requirements, batch requirements, Service level management is a proven methodology Medium potential impact to smaller number of users or 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. high-quality service. threshold for special attention. can be a required field for all change submissions. individual service performance issues. Performance Management. Note: Performance problems are usually related to capacity. capacity and performance management processes. Performance management is the practice of managing network service response time, consistency, and quality for individual and overall services. KPI Library is a community for performance management professionals.
