[cas-dev] application monitoring

[Julien Marchal]

We Use statistics inCAS3 with Inspektr
We have just made a jsp to expose stats in HTTP

<%@ page import="java.util.*"
%><%@ page 
import="org.esupportail.cas.statistics.support.InMemoryStatisticManager"
%><%
Set<String> ensemble = InMemoryStatisticManager.statsVal.keySet();
for(String s : ensemble) {
    out.println(s + " : " + InMemoryStatisticManager.statsVal.get(s));
}
%>

and we use cacti (http://www.cacti.net/) to graph this.
I joint a graph by example.

Thanks,
