We've been using Lambda Probe to monitor our Tomcat 6.0.18 estate for a while now.
Recently we have been migrating to clustered configurations and would like to be able to monitor status of the clusters.
This is not supported by Lambda Probe, which appears to be a dead app now. Does anybody have a similar story? What avenue did you take to provide this type of monitoring? We're also looking at Nagios as part of an overall monitoring solution project.
