Monitor port group performance
Does anyone have a nice way to monitor port group ASIC performance for a Cisco director? I have found a way in Device Manager to check point-in-time statistics for a port-group oversubscription by clicking on the "Over subscription" option when you right click a blade. However, the downside to this is that it is only a current estimate so not good for tracking over time.
We are just trying to keep an eye on some applications with unknown utilization profiles to make sure they do not impact other things in the group and require us to move.
We do not have the full blown Fabric Manager suite licensed and use ECC for monitoring/performance statistics. The current "work-around" we have involves a custom view that sums the ports that comprise a port-group, but that is not ideal.
Any slick solutions/suggestions or experience tackling this?

Hello,
It depends exactly what statics you want to pull. PM should be able to provide many of them, but in some instances it may be able to provide exactly what you want. Please always consult the appropriate PM guides to ensure that the statistics you want to collect are included. I would also recommend discussing your exact needs with your EMC Professional Servces Engineer to see what solutions are available that can provide the information. If they are not currently available via PM, a special tool may be available to pull the information or an enhancement request could be created to add it.
Thank you.- The specific metric is "Port Group Oversubscription" which is a value you can check on within Device Manager for a current point-in-time check.
Have worked with our local Sales Engineer and he is researching this as well and the final answer may be that we need to submit an enhancement request. Just trying to see if someone else has found a clever way to do this. - You can't look it up AFAIK.
All port groups in the MDS91xx range are line rate and line cards for the 92xx and 95xx have a 12.8Gbps bandwidth for each port group.
So if you have a 12 port line card, each port is line rate
If you have a 4 ports 10Gb line card, each port is line rate
If you have a 24 port line card, there's 6 ports per 12.8 Gbps, so about 2:1 over subscription
