What is the preferred way to monitor/count the maximum number of concurrent TCP connections across a router over a set interval?
Is there a MIB one can poll? Does one need to look to Netflow? Is there something one can report from a SHOW command? How about a 3rd party tool?
Packetshaper contains a variable peak-tcp-conns that pretty much describes what I'm looking for if I had one of their appliances: "Highest number of simultaneous TCP connections recorded for the interval".
TIA

Provide more info about your questions ie topology details and what device you are using in your network.

7 site network running MPLS with MLPPP (nxT1s) on 2800 series routers and a DS3 on a 3800 series router at HQ. ADVSECURITYK9-M IOS software on all devices so as to have BGP routing between CPE and carrier.
Need more info? Please be more specific.
Thanks

There is no MIB OID that currently exists to show the concurrent connections.
About the closest you'll get via snmp is apFlowMgrPortCurrTCPFlows (.1.3.6.1.4.1.9.9.368.1.36.16.1.10) which may not be supported on you device depending on the type

Hhhhhhmmmmmm
http://tools.cisco.com/Support/SNMP/do/BrowseOID.do doesn't list this as being a supported OID under IOS. In fact the whole 368 tree isn't present.
Do you have the correct OID?
Thanks
