SNAT statistics and iRule for selecting SNAT IP
Hi,
I am trying to setup Exchange 2010 via the BigIP utilizing a SNAT pool.
Following the iApp from [1] and the deployment guide linked there [2] I am using the following iRule to ensure SNAT addre...

Is this a bug or expected behaviour?
i understand it is expected because you manually specify snat address.
If expected, can I somehow update the statistics from within this iRule somehow?
you may try istats.

Just for the sake of completeness: Finally I did not use istats because we have splunk in place here and for this to work I did add the following line to the iRule to log:
log local0. "EXCHANGE_2010_SNATPOOL snat_ip=[lindex $static::snpool [eval {expr $packed_address % [llength $static::snpool] }]]"
Then in Splunk I use the following search string to create a graph for the distribution of the connections per SNAT IP:
index=f5 EXCHANGE_2010_SNATPOOL NOT lindex | timechart count by snat_ip
Alternatively this can be used if you need a percentage:
index=f5 EXCHANGE_2010_SNATPOOL NOT lindex | top snat_ip
