WAAS Capacity Planning TFO Connection Reporting?

For WAAS Capacity Planning I'm trying to work out a way to gather WAAS appliance and module TFO connection statistics over time for each device. I'm looking to gather the number of TFO connections at regular intervals to allow us to get an accurate picture of the current WAAS capacity utilisation. The central manager reports a "The TFO accelerator is overloaded (connection limit)" when the maximum TFO connection limit for a devices is exceeded but it does not tell you the number of connections that exceeded the limit on the box.

I've tried using the WAAS Monitoring XML API:

http://www.cisco.com/en/US/docs/app_ntwk_services/waas/waas/v421/monitoring/guide/MG_XML_API.html

But it does not allow reporting of this statistic as far as I can work out.

If you run "show stat conn" on a WAAS device it gives you the "Current Active Optimized Flows", but this is the current number of flows and not the maximum number of TFO connections reached since the counters were last cleared?

Current Active Optimized Flows:                                3258

   Current Active Optimized TCP Plus Flows:              812

   Current Active Optimized TCP Only Flows:              2453

   Current Active Optimized TCP Preposition Flows:    0

Current Active Auto-Discovery Flows:                         411

Current Reserved Flows:                                           99

Current Active Pass-Through Flows:                          540

Historical Flows:                                                      532

Does anyone know anyway of anyway to either manually gather this statistic from a WAAS appliance or module? Or poll this statistic from a monitoring system like Solarwinds?

WAAS Capacity Planning TFO Connection Reporting?

Hello

As of WAAS 4.4.1 it comes with a WAN optimization MIB CISCO-WAN-OPTIMIZATION-MIB, if you want to use a 3rd party software like Cacti to graph over time.

http://www.cisco.com/en/US/customer/docs/app_ntwk_services/waas/waas/v441/configuration/guide/SNMP.html#wp1141055

This MIB provides information about the status and statistics  associated  with the Application Optimizers.The following objects from  this MIB are  supported:

#

cwoAoStatsIsConfigured

#

cwoAoStatsIsLicensed

#

cwoAoStatsOperationalState

#

cwoAoStatsStartTime

#

cwoAoStatsTotalHandledConn

cwoAoStatsTotalOptConn

#

cwoAoStatsTotalHandedOffConn

#

cwoAoStatsTotalDroppedConn

#

cwoAoStatsActiveOptConn

#

cwoAoStatsPendingConn

#

cwoAoStatsMaxActiveOptConn

This MIB also provides information about TFO statistics. The following objects are supported:

#

cwoTFOStatsTotalHandledConn

I would recommend you to go through the following document, it could help you to archive your goal.

Re: WAAS Capacity Planning TFO Connection Reporting?

Thanks for that. I've read through the document section and it cover how to troubleshoot a "TFO overload" however we are trying to track TFO connection stats for reporting and capacity planning.

Re: WAAS Capacity Planning TFO Connection Reporting?

I believe the "show statistics tfp detail", under the "Policy Engine Statistics" section, then "Rejected Connection Counts Due To: (Total: xx)", you have "Connection Limit", which shows the number of connections been rejected by TFO duo to reaching the device connection limit isnt this what you are looking for?

Best regards,

Ahmad

Re: WAAS Capacity Planning TFO Connection Reporting?

Hi,

As of WAAS 4.3.1 we introduced the connection trend report which will give you # of optimized connections over time.
