History active connections WAAS (WAE)

[Harrisson Braga]

Hi Folks!

     I need extract the history active connections from WAE-512 and WAE-612. For example, in hour XX:XX I was X number of active connections.How I can do this? It´s possible? Exist SNMP OID to collect this information if not is possible in Central Manager?

Thanks.

Hi Harrisson,

WAAS will not keep history of connection counts. To keep the history of these counts, you can use NetFlow collector to collect the information. Central Manager will not keep the history of connection counts.

Hope this helps.

Thanks for you answer!

   I´ll try make the lab about this to see what is possible in relation to the collection related to WAAS. Any more comments ?

Hi Harrisson,

Thanks for marking this Answered.

You can use WAE Central Manager to export these numbers to any NetFlow analyzer.

WAAS does flow the agent to any netflow collector / analyzer. NetQoS and NAM can understand this traffic directly where as you will need additional customized api if you want to export the stats from WAAS to others.

All these APIs are publicly available and listed here: http://www.cisco.com/en/US/products/ps6870/products_programming_reference_guides_list.html

Cisco WAAS reporting using NetFlow can be done with almost any NetFlow collector that supports both ingress and egress flows.  One of the 3rd party has posted this on their website.  Best Practices blog releated to Cisco WAAS and NetFlow.

Hope this helps.

Hi Harrisson,

I don't known if you solve this problem but I used a MRTG monitoring the MIB-II variable tcpCurrEstab through SNMP.  This variable has the number of Established or Close-Wait TCP connections in a moment.  I made the SNMP poll in the central WAE.
