Hello Ceki Gülcü, >How is does SQLWatch integrate with log4jdbc? Is it by intercepting >logging requests? Here is tool implementation overview diagam (how it works currently): http://code.google.com/p/sqlwatch/source/browse/trunk/sqlwatch2/doc/overview/sqlwatch.png
Actually yes, SQLWatch listens log-messages passed from log4jdbc and then notifies all custom listeners which do it's own jobs (like preparing profiling report and so on). > As for "handlers", SLF4J only deals with loggers. It does include a > notion of handlers in j.u.l. terminology (appenders in log4j and > logback). If I understand, custom wrapper for log-library (e.g. wrapper for log4j) in slf4j is something like handler. But in difference to JDK (Log) Handler I can't add more than 1 handler (wrapper for logging library) to SLF4J same time. In this case I have at least two solutions: 1. implement a Proxy Wrapper (but how to attach it to slf4j in most natural way) which will notify SQLWatch and pass all other log-messages to concrete wrapper (e.g. log4j wrapper). 2. Impelment all kinds of Listeners/Appenders for all possible log-libraries. May be here is some other (and better!) solutions, and if not, which one is better? -- Dmitry
