Hi Sunay, To explain shortly what are doing, technically, at InfoVista:
- We discover a infrastructure environment (networks, systems, applications) and determine which metrics to collect and the best to collect them - We feed our centralized database (marketing call it CMDB, it is based on oracle OEM) with all these inventory information - our centralized system launch the data collection and start reports. It calculate as well advanced KPIs from root metrics - We create web based reports on the whole infrastructure, with performance data, trending, prediction ... and real time alerts as well when we detect bad trending. Today we support most of network config in the world (this is our primary market) and we cover many system & apps config as well (we support all unix, linux & win OS, we collect through SNMP, WMI and DTrace remotely, we can collect as well from BMC Patrol API and Tivoli SSM Agent). Concerning metrics in the network environment, the main high level categories are: The main interest with crossbow are Interface (NIC & VNIC) and all related to QoS (flows) Concerning metrics, the very primary requirement are around MIB2 definition: - Traffic In/Out (%, bps & Bytes), Error In/Out (%, #). If possible, discard & broadcast, don't know if this applicable for crossbow. - Concerning flows: very similar to previous, but by application. In Cisco world, we have as well "queue" info to tell us if the flows is saturating. But the challenge is more in the discovery phase. We need some config information: - NIC & VNIC: bandwidth limit, IP / Mac. - For VNIC: identify which physical NIC is related to this Virtual NIC. This is, for example, similar to identify a MPLS interface in a router, that is logical interface related to a physical interface. In Cisco world, we identify that using IfIndex of interfaces. - For flows: application and limit configured. - Also, it will be very good to identify which VNIC is associated to which Zone. But it is something that InfoVista discovery tool can discover automatically The best for first step is to support MIB2 that describe all of that and is standardized in InfoVista.

VNICs should show up as IF in those bits. You can derive the B/W limit set on the NIC or VNIC by looking at the link speed in the MIB. Exposing the other attributes and flows will need a bit more work and we are looking at it. BTW, can you describe a little bit more what you are doing and what other kind of things you need to see. We are also working on defining our APIs and Dtrace hooks to get you more visibility into the stack, NICs, VNIC and flows including real time usage, history etc. So it would be good to work with people like you to make sure it meets the need.
