I would think so. We have our own that reports heap usage, database connection pool usage, and the patch level of the JVM. We can use it to graph memory usage over long periods of time using whatever sampling rate we choose, because it's all based upon when the request is made. Every 5 minutes? No problem. Every 5 seconds? Just change the cron job. :) - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAkuETK8ACgkQ9CaO5/Lv0PCdVwCfWqWqmEloAvZvjDCuGs8LdTzh C0UAoKOxjXHGvi0QoOPQkhyvjl9uStn2 =Uxtn -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
