Displaying HTTP keep-alive statistics
You can use the show server proxy keep-alive command to display HTTP keep-alive statistics. The
statistics relevant to HTTP keep-alive are shown (in bold) in the following abbreviated output and
described in Table 5.
NOTE
With the ServerIron ADX release 12.4.00e, the show server proxy keep-alive command will display
hash bucket counters for tracing the reason why a persist based on hash-to-bucket CSW policy failed
during traffic flow. The counters are also shown (in bold) in Table 5.
