Used the same options to generate the tcpdump file as if in Mysql: tcpdump -s 65535 -x -nn -q -tttt -i eth0 -c 1000 port 8890 And I got this error: ./mk-query-digest --type http http.log Pipeline process 3 (HTTPProtocolParser) caused an error: Use of uninitialized value in string eq at ./mk-query-digest line 9854 Is there any specific options in tcpdump to format the output file?

I'm wondering : at some point, "realtime" sampling, collecting and displaying interesting stat data for adminsys could be implemented by many different and interoperable tools ? For instance asql already samples and collects many type of events but has no display/analysis facility, etc. In between Pinba and basic HTTP log analysis, you could use http://forge.bearstech.com/trac/wiki/PhpTop for a poorman’s profiler (plug: I’m its author).

What you are really saying is, it's not useful for understanding why the request is slow. It is extremely useful for *finding* slow requests.

I think a simple web server log/tcpdump is not usefull for finding slow http queries. Generaly we need info about parsing, calculating, io/wait, network wait (mysql,memcached,web services), network response time (from web server to client) How about pinba for php load reporting?
