performance monitoring and network statistics

TotConns is the total number of connections that have been handled, while MaxConns is the highest number of connections that had ever been handled at one time.

For the purpose of monitoring connection rate you want to use TotConn. The connection rate is the difference between the current TotConn and previous TotConn divided by the number of seconds between the two samples.

For example, if I'm collecting SNMP statistics every 60 seconds, my connection rate would be as follows. TotConn1 = the value of TotConn in the previous polling period TotConn2 = the value of TotConn in the current polling period

(TotConn2 - TotConn1) / 60

So if: TotConn1 = 4000 TotConn2 = 6000 there have been 2,000 new connections over the last 60 seconds

Connection rate = (6000 - 4000) / 60 == 33.3 (33.3 CPS over the last minute)

Finally, when calculating LTM performance statistics be sure that you calculate client-side and server-side statistics separately. Don't add the client-side and server-side TotConn values. Instead, generate separate client-side and server-side statistics.
