Which three are valid methods to monitor and trend SAN port channels with DCNM? (Choose three.)
A. use summary view in the device manager
B. from the DCNM-SAN client, view ISLs in real time from the Performance drop-down list
C. for each port channel, select Monitor Continually
D. configure traps for each port channel to utilize RMON
E. set up flows with the DCNM-SAN client and use the Performance Manager web client for performance collections
Correct Answer: ABE

Explanation:
Device Manager provides two views: Device View and Summary View. Use Summary View to monitor interfaces on the switch. Use Device View to perform switch-level configurations including the following configurations:
Configuring virtual Fibre Channel interfaces
Configuring Fibre Channel over Ethernet (FCoE) features
Configuring zones for multiple VSANs
Managing ports, PortChannels, and trunking
Managing SNMPv3 security access to switches
Managing CLI security access to the switch
Managing alarms, events, and notifications
Saving and copying configuration files and software image
Viewing hardware configuration
Viewing chassis, module, port status, and statistics
DCNM-SAN Web Client
With DCNM-SAN Web Client you can monitor Cisco MDS switch events, performance, and inventory from a remote location using a web browser.
Performance Manager Summary reports — The Performance Manager summary report provides a high-level view of your network performance. These reports list the average and peak throughput and provides hot-links to additional performance graphs and tables with additional statistics. Both tabular and graphical reports are available for all interconnections monitored by Performance Manager.
Performance Manager drill-down reports — Performance Manager can analyze daily, weekly, monthly and yearly trends. You can also view the results for specific time intervals using the interactive zooming functionality. These reports are only available if you create a collection using Performance Manager and start the collector.
Zero maintenance database for statistics storage — No maintenance is required to maintain Performance Manager’s round-robin database, because its size does not increase over time. At prescribed intervals the oldest samples are averaged (rolled-up) and saved. A full two days of raw samples are saved for maximum resolution. Gradually the resolution is reduced as groups of the oldest samples are rolled up together.
Performance Manager
The primary purpose of DCNM-SAN is to manage the network. A key management capability is network performance monitoring. Performance Manager gathers network device statistics historically and provides this information graphically using a web browser. Performance Manager presents recent statistics in detail and older statistics in summary. Performance Manager also integrates with external tools such as Cisco Traffic Analyzer.
Performance Manager has three operational stages:
Definition — The Flow Wizard sets up flows in the switches.
Collection — The Web Server Performance Collection screen collects information on desired fabrics.
Presentation — Generates web pages to present the collected data through DCNM-SAN Web Server.
Performance Manager can collect statistics for ISLs, hosts, storage elements, and configured flows. Flows are defined based on a host-to-storage (or storage-to-host) link. Performance Manager gathers statistics from across the fabric based on collection configuration files. These files determine which SAN elements and SAN links Performance Manager gathers statistics for. Based on this configuration, Performance Manager communicates with the appropriate devices (switches, hosts, or storage elements) and collects the appropriate information at fixed five-minute intervals.
