[cosmic-users] monitoring of running systems

At this point of time there is no tool in CoSMIC which does this.

I am working on Target Manager which provides a resource provisioning 
interface to book resources for components. As an extension to this 
work, I am also working on monitoring a running application and to 
characterize it's behavior in terms of resource usages. By resources, I 
mean both hardware and software resources. Such monitoring will help in 
two ways, first it will enable run-time detection of interesting events 
in the system such as component failure, resource starvation etc., 
second to create a profile of an application which will help in 
allocating it in future deployments.

 The monitoring techniques use both internal and external probes to 
measure performance. Overhead of such probes is an interesting aspect 
which I am investigating.

    I can think of some tools based on JBoss which does something 
similar to this. JBoss has an interface which tells all details about 
the JVM, what all components are installed, how much cpu is used etc. 
There are also other tools which use these interfaces in the JVM. Here 
is a tool which does management of JBoss servers 
http://www.hyperic.com/products/managed/jboss-management.htm . This one 
looks more towards what you are looking for, it has monitoring 
capabilities for J2EE, .NET, Oracle etc

 Let me know, if you have any questions.

  HTH,
