You could turn on the AccessLogValve and then simply look at the log files. Another option would be to write your own Valve or Filter and record the accesses yourself, but the AccessLogValve is already there. I think it can easily be configured to emit "standard" httpd-style logs so you can use tools webalizer to graph the usage over time and stuff. > JAVA_OPTS="-server -Xms128m -Xmx384m > -Djava.library.path=/usr/src/dbxml-2.2.13/install/lib/" Really? From your other message, you make it look like Java is taking something like 1GB of memory. Sure, the JVM adds some overhead to the heap size you configured, but it shouldn't be more than 5% or 10%... nothing like 200%. > OK.

If you really are only serving 10 users per minute, attaching a memory profiler isn't going to significantly impact your performance (unless you're running with an old VM which requires disabling the JIT in order to instrument the VM). You said you're running 1.5.0, which should allow this type of instrumentation. > :)). I had this experience once - it's hard to believe char[] are > so evil! :). Not evil... just plentiful. All those class and method names gotta go somewhere! - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFHVXy89CaO5/Lv0PARAny+AKCiGeKbj2mdkcA/VMs5Ov9eZeO4ygCeMqrG w08hluEeYuVtcl0Piszaas4= =YG+c -----END PGP SIGNATURE----- --------------------------------------------------------------------- To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
