Get statistics(this howto is deprecated)Tag(s): DEPRECATED


The component Jaguar/Monitoring is used to extract the statistics related to particular activities hosted by Jaguar.

First here a class containing useful constants.

All the following examples use this method to align the numbers.
static String pad10(double[] data, int item, short[] keys) {
        String s = "" + data[item];
        if (s.endsWith(".0")) {
            s = s.substring(0, s.length() - 2);
        }
        if (item < keys.length - 1) {
            s = s + ",";
        }
        while (s.length() < 10) {
            s = s + " ";
        }
        return s;
}
For the server
protected void doServer(java.io.PrintWriter out) {
    java.util.Properties props = new java.util.Properties();
    props.put("org.omg.CORBA.ORBClass", "com.sybase.CORBA.ORB");
    ORB orb = ORB.init((String[])null, props);
    Monitoring jm =
       MonitoringHelper.narrow(orb.string_to_object
         ("Jaguar/Monitoring"));
    out.println("<h1>Server Stats</h1><pre>");
    out.println("");
    out.println
    ("Jaguar    Component                     Transaction         Server");
    out.print
      ("--------  ----------------------------  ------------------");
    out.println("  --------------------------------------");
    out.print
      ("counter:  invoke    active    pooled    complete  rollback");
    out.println("  sessions  requests  rd bytes  wr bytes");
    double[] data = jm.monitor("Server", "", StatsConstants.keys);
    int item = 0;
    out.print("\ncurrent,  ");
    for (int j = 0; j < StatsConstants.keys.length / 3; j++, item++) {
        out.print(pad10(data, item, StatsConstants.keys));
    }
    out.print("\nlastMax,  ");
    for (int j = 0; j < StatsConstants.keys.length / 3; j++, item++) {
        out.print(pad10(data, item, StatsConstants.keys));
    }
    out.print("\npeakMax,  ");
    for (int j = 0; j < StatsConstants.keys.length / 3; j++, item++) {
        out.print(pad10(data, item, StatsConstants.keys));
    }
    out.println("</pre>");
}
For connection caches
    protected void doConnCache(java.io.PrintWriter out) {
        java.util.Properties props = new java.util.Properties();
        props.put("org.omg.CORBA.ORBClass", "com.sybase.CORBA.ORB");
        ORB orb = ORB.init((String[])null, props);
        Monitoring jm =
          MonitoringHelper.narrow(orb.string_to_object
             ("Jaguar/Monitoring"));
        out.println("<h1>Connection caches stats</h1><pre>");
        out.println("");
        out.println("Cache     ");
        out.print
         ("--------  ----------------------------  ------------------");
        out.println("  --------------------------------------");
        out.print
         ("counter:  active    closed    invoked   forced    opened    ");
        out.println("nowaited  reopened  waited");
        double[] data = jm.monitor
           ("Connection Cache", "", StatsConstants.connkeys);
        int item = 0;
        out.print("\ncurrent,  ");
        for (int j=0;j<StatsConstants.connkeys.length / 3;j++,item++) {
            out.print(pad10(data, item,StatsConstants.connkeys));
        }
        out.print("\nlastMax,  ");
        for (int j=0;j<StatsConstants.connkeys.length / 3;j++,item++) {
            out.print(pad10(data, item, StatsConstants.connkeys));
        }
        out.print("\npeakMax,  ");
        for (int j=0;j<StatsConstants.connkeys.length / 3;j++,item++) {
            out.print(pad10(data, item, StatsConstants.connkeys));
        }
        out.println("</pre>");
    }
For a specific connection caches
    protected void doCache(java.io.PrintWriter out, String name) {
        java.util.Properties props = new java.util.Properties();
        props.put("org.omg.CORBA.ORBClass", "com.sybase.CORBA.ORB");
        ORB orb = ORB.init((String[])null, props);
        Monitoring jm =
          MonitoringHelper.narrow(orb.string_to_object
            ("Jaguar/Monitoring"));

        out.println("<h1>Connection Cache Stats [" + name + "]</h1><pre>");
        out.println("");
        out.println("Cache     ");
        out.print
         ("--------  ----------------------------  ------------------");
        out.println("  --------------------------------------");
        out.print
         ("counter:  active    closed    invoked   forced    opened    ");

        double[] data = jm.monitor
          ("Connection Cache", name, StatsConstants.connkeys);
        int item = 0;
        out.print("\ncurrent,  ");
        for (int j=0;j<StatsConstants.connkeys.length / 3; j++, item++) {
            out.print(pad10(data, item,StatsConstants.connkeys));
        }
        out.print("\nlastMax,  ");

            out.print(pad10(data, item, StatsConstants.connkeys));
        }
        out.println("</pre>");
    }
For a package or component
protected void doComponent
   (java.io.PrintWriter out, String type, String name) {
        java.util.Properties props = new java.util.Properties();
        props.put("org.omg.CORBA.ORBClass", "com.sybase.CORBA.ORB");
        ORB orb = ORB.init((String[])null, props);
        Monitoring jm =
           MonitoringHelper.narrow
             (orb.string_to_object("Jaguar/Monitoring"));

        out.println("<h1>Stats for " + type + " [" + name + "]</h1><pre>");
        out.println("");
        out.println("Component    ");
        out.println
           ("--------  ----------------------------  ------------------");
        out.println
         ("counter:  invoke    active    pooled    complete  rollback");
        double[] data = jm.monitor(type, name, StatsConstants.compkeys);
        int item = 0;
        out.print("\ncurrent,  ");
        for (int j=0;j<StatsConstants.compkeys.length / 3; j++, item++) {
            out.print(pad10(data, item,StatsConstants.compkeys));
        }
        out.print("\nlastMax,  ");
        for (int j=0;j<StatsConstants.compkeys.length / 3; j++, item++) {
            out.print(pad10(data, item, StatsConstants.compkeys));
        }
        out.print("\npeakMax,  ");
        for (int j=0;j<StatsConstants.compkeys.length / 3; j++, item++) {
            out.print(pad10(data, item, StatsConstants.compkeys));
        }
        out.println("</pre>");
}
The above snippet will show stats for a complete package or a component in a package.
package:
  doComponent(out, 'Package', 'MyPackage')

component:
  doComponent(out, 'Component', 'MyPackage/MyComponent')
