Hi,

I think analyzing via tcpdump will not help. Apache logs do not show internal requests when we access the home page.

I think I might see some backend function; as in controllers; which accesses the elasticsearch to collect some data; account the logs of the last 24 hours; host numbers; etc.

I am trying to analyze the codes, however they are protected.

The last column is the time taken

Code: Select all

# tail -f access_log_with_response_time

The logs may not show it but the tcpdump would and does show the requests. It looks like the data that the tcpdump that was provided ran for much longer than was necessary and it's hard to filter out the noise. At this point I'd like if you could open a ticket and we can schedule a remote so I can take a closer look and gather some info.
