We've been doing this lately to great success. You can use a tool like rrdtool to store the data and generate nice-looking graphs over time. You can also easily use the same feed to do real-time monitoring using a tool like Nagios, Ichinga, etc. > 3) Use a command-line JMX tool like jmxsh > (http://code.google.com/p/jmxsh/) to extract information and parse > out whatever you want. While this is a tempting idea, when you start probing many different values via JMX, you'll find that starting a dozen JVMs and connecting via JMX starts to strain the server unnecessarily. That's why I recommend using JMXProxyServlet -- you get the power of JMX without actually making a JMX connection. - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG/MacGPG2 v2.0.17 (Darwin) Comment: GPGTools - http://gpgtools.org Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAk96AuMACgkQ9CaO5/Lv0PAMqwCgnMEf3G54uFmERY1h/ezDRhCk aKIAnibgy+FJlo2Qcr87iOE6+43EP+gR =NIfs -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
