I have three questions regarding the "show stats connection" command in the ACE 4710:
1. What is the criteria for a connection to be added to the "Total Connections Failed" counter?
2. What is the criteria for a connection to be added to the "Total Connections Timed-out" counter?
3. Is there a command to get more information why the connection was failed or timed-out (e.g. to/from which IP, url accessed etc.)?
Thanks in advance for your help!
yes, HSRP, VRRP will be counter as failed connections.
a connection failed if the server did not respond or resonded with a RST.
As long as the connection gets establised, it is counted as a success.
The connection timeout counter is incremented when the connection is idle for the configured timeout value or for L7 connections if it does not complete the 3-way handshale within the embryonic timeout interval.
Since this is clear why those counters are incrementing, the only way to get more information is to capture a sniffer trace to verify if the conditions above are met.
