The goal of JavaMelody<\/a> is to monitor Java or Java EE application servers in QA and production environments.<\/p>\n

\"JavaMelody<\/p>\n

The really nice thing is sthe storage of historical data – you can have a look at the same graphs spanning a week, a month or a year without setting up any additional infrastructure. Therefore JavaMelody is installed on every production system I work on.<\/p>\n

Securing JavaMelody Installation<\/h1>\n

If you want BASIC authentication with username and password, but do no want to use a realm and “security-constraint” in web.xml, you can add the parameter “authorized-users” in web.xml, in context or in system properties like the other javamelody parameters (since v1.53). For example in your WEB-INF\/web.xml file:<\/p>\n

\n
<filter><\/span>\n        <filter-name><\/span>monitoring<\/filter-name><\/span>\n        <filter-class><\/span>net.bull.javamelody.MonitoringFilter<\/filter-class><\/span>\n        <init-param><\/span>\n                <param-name><\/span>authorized-users<\/param-name><\/span>\n                <param-value><\/span>user1:pwd1, user2:pwd2<\/param-value><\/span>\n        <\/init-param><\/span>\n<\/filter><\/span><\/code><\/pre>\n<\/div>\n
Security Manager<\/h1>\n
If you are running into an active security manager the following snippets helps<\/p>\n
\n
grant codeBase \"file:${catalina.home}\/webapps\/<your_webapp>\/WEB-INF\/lib\/javamelody-x.jar\" {\n        permission java.security.AllPermission;\n};\ngrant codeBase \"file:${catalina.home}\/webapps\/<your_webapp>\/WEB-INF\/lib\/jrobin-1.5.9.1.jar\" {\n        permission java.security.AllPermission;\n};    \u00cf<\/code><\/pre>\n<\/div>\n
