CHAPTER 1IntroductionThe CA NetQoS Multi-Port Collector is a powerful server that captures and processes large amountsof data at an extremely high rate. The increased capacity and processing power make more dataavailable for reporting in CA NetQoS SuperAgent. By passively monitoring large volumes of datacenter traffic from multiple ports, the Multi-Port Collector helps SuperAgent keep a continuousrecord of end-to-end system performance.With the default filtering options in place, packet headers from all traffic passing through themonitored SPAN ports are recorded and stored on the Multi-Port Collector for a short period oftime. Data taken from one-minute reporting intervals is kept for a period of a few days and providedfor on-demand analysis. Metrics are also forwarded for reporting in the SuperAgent ManagementConsole.Charts and tables on the Multi-Port Collector Analysis page show per-host activity and performancedata, with multiple views of sessions, volume statistics, and response times. The same Web-basedinterface also offers SuperAgent troubleshooting workflows, flexible reporting that can be easilyshared with coworkers, and multiple data filtering and sorting options to help IT staff diagnose andrespond to reported issues.This Multi-Port Collector User Guide provides information about product installation, features, andadministrative tasks. The latest version of the User Guide is always available from the CA SupportWeb site: http://support.ca.com.This chapter describes the CA NetQoS Multi-Port Collector and explains how it works in yourenvironment. It covers the following topics: “Features and Benefits” on page 2 “Product Components” on page 5CA NetQoS Multi‐Port Collector 2.1 User Guide1
IntroductionFEATURES AND BENEFITSThe CA NetQoS Multi-Port Collector increases the capacity and flexibility of NetQoS SuperAgentdata collection. The greatly expanded collection capabilities of the CA NetQoS Multi-Port Collectorallow it to process SuperAgent metrics with a capacity that exceeds multiple Standard Collectors,reducing the cost of SuperAgent ownership.Unlike the SuperAgent Standard Collector, the Multi-Port Collector can capture and process datafrom multiple links. Depending on the Multi-Port Collector configuration you purchased, it canmonitor either eight or four 1-Gigabit/second (Gbps) links, or two 10-Gbps links. The Multi-PortCollector also includes a high-performance database to store data related to network, server, andapplication performance at a finer granularity.The Multi-Port Collector stores packets for a short period of time to support the SuperAgent packetcapture investigations feature. This feature allows for both on-demand investigations and historicalanalysis of system performance, based on packets captured at the time an incident occurred.The Multi-Port Collector both enhances and supplements SuperAgent reporting. The same data thatis reported in SuperAgent at five-minute intervals can be displayed in tables and charts and analyzedon the Collector Analysis page at one-minute intervals. The more granular metrics, which includesome Collector-only performance data, provide full details about individual hosts.Multi-Port Collector Support for CA NetQoS SuperAgentThe Multi-Port Collector aggregates and exports metrics to one SuperAgent Management Console ina form compatible with a SuperAgent Standard Collector, version 9.0 or later. It was designed toimprove the capacity and flexibility of SuperAgent data collection while lowering the cost ofownership in large network environments. It provides an alternative for enterprises that require highvolume monitoring with more flexibility and less overhead.Packet storage on the Multi-Port Collector allows you to perform enhanced packet-captureinvestigations in SuperAgent. With a SuperAgent Standard Collector, these investigations onlycapture the packets that are sent after the investigation is initiated. By contrast, the capture files storedon the Multi-Port Collector allow you to look back in time for forensic analysis of a performanceissue.With a Multi-Port Collector and a SuperAgent Management Console, you can: Monitor the same SuperAgent metrics and some additional, detailed metrics, while using a singleappliance to process a network throughput rate equivalent to multiple SuperAgent StandardCollectors. View data at one-minute granularity, and choose from multiple chart types. Generate packet-capture investigation files taken at the time the incident occurred, and store thosefiles for up to 90 days. Perform rapid, accurate detection of networks, servers, and applications, configure the itemsspec
