Poor man’s traffic logger


I was reading the following blog post about filtering out MySQL queries and was reminded of a situation I faced once. The situation was as follows: I needed to find out where certain PostgreSQL queries were coming from, however the server was behind a pgpool instance, so all the queries were seen as coming from the same IP.

The solution was to tcpdump on the interface/port where pgpool was listening and search the traffic for the specific queries. This solution is much more elegant of course :-). Also, somebody in the comments mentioned a nifty little tool called MySQL query sniffer, which looks very nice and probably could be adapted for PG (using something like PgPP as the basis).
