LambdaProbe for Tomcat 1.7

Lambda Probe is designed for Apache Tomcat and only Apache Tomcat.
It will not work with any other application server. Lambda Probe has been
tested with Java 1.4 and Java 1.5 and I found it to be working perfectly on both. It is also compatible with
Tomcat5 versions 5.0.x and 5.5.x. Unfortunately it is not compatible with older versions such as 4.1.x and 3.3
because of lack of EL support in JSP 1.2.

Version 1.7b

  • Fixed bug where LambdaProbe may fail to startup if stats file is corrupt.
  • Fixed incorrect interpretation of org.jstripe.intruments.ignoreNIO system property.
  • Added support for Tomcat 6.
