5 New UI framework with improved extensibility New and improved Dashboards SharePoint integration with the OM Web Console Improved monitoring for Unix/Linux machines

6 On Demand Network Discovery Support for Windows Workflow Foundation 4.0 New SNMP Stack

8 Out of the box discovery, monitoring, dashboards & reporting. Server to network dependency discovery. Multi-vendor support: Over 80 vendors-2000 devices certified Multi protocol support SNMPv1/v2c/v3 IPv4 and IPv6

9 Bridges Firewalls Load Balancers Routers/Switches/Hubs Hosts

10 SNMP Overview

11 SNMP Components SNMP Communications MIB tree structure How are OID s formed?

12 Managed Devices SNMP Agents SNMP V1, SNMP V2c, SNMP V3

13 MIB: Management Information Base. It is a collection of information organized hierarchically OID: Object Identifiers that uniquely identify managed objects in a MIB hierarchy.

14

15 Assigned in hierarchical fashion Each number identifies a node in the MIB tree Internet Community (IANA) Directory ( ) Mgmt ( ) Experimental ( ) Private ( )

16

17 Connectivity: server to switch, switch to switch VLAN membership HSRP groups Stitching of switch ports to server NICs Key components of a device: ports/interfaces, processor, memory

18 Explicit discovery Customer knows the network devices. Manual process add ip address or import list Recursive Discovery Network topology unknown Discovered based on a set of seed devices Grabs ARP and IP tables and crawls network

19 Initial Probing Sends an initial ICMP and/or SNMP request to identify the system. Processing Get components, IP addresses, VLAN memberships, resources, IP networks, netmasks, and neighboring devices. Topology is created Post Processing Creates Layer 2 and Layer 3 connectivity between the devices in the topology. Port Stitching

20 ICMP Ping and/or SNMP Get (v2 by default) ICMP ping first SNMP get next If no response device added to pending If SNMPv2c fails -> SNMPv1

21 Matches sysobjectid = OID in oid2type config files found C:\Program Files\System Center Operations Manager 2012\Server\NetworkMonitoring\conf\ Gets details on components, IP addresses, VLAN memberships, resources, IP networks, netmasks, and neighboring devices. Identify device type (Switch, Router, Hub, etc.), vendor, model, certification level Levels of Certification Certified - has been successfully tested using standard and proprietary MIBs supplied by the vendor. Generic - The OID is unknown, only the availability of the device will be monitored.

22 Creates Layer 2 and Layer 3 connectivity between the devices in the topology. "Port Stitching" - Mapping IP and MAC access points retrieved from the ARP cache to the appropriate devices. Removes MAC access points that do not belong to devices in the topology A MAC Access Point is the interface to which a device on an IP network connects Creates network connections to represent WAN, or logical connections

24

25 Support Resource Pools for High Availability Monitoring. Only certain ports will be monitored by default Ports connecting two network devices to each other Ports to which a managed server is connected

26 Port/Interface Up/Down (operational & admin status) Volumes of inbound/outbound traffic % Utilization Discards, Drops, Errors Processor % Utilization Memory In depth memory counters (Cisco Only) Free memory

27 Connection Health Based on looking at both ends of a connection VLAN Health Based on health state of switches in VLAN HSRP Group Based on health state of individual HSRP end points
