How can I do the equivalent of:
@Override
public void init(final ServletConfig config) throws ServletException {
super.init(config);
CsvReporter.enable(new File("/tmp/measurements"), 1, TimeUnit.MINUTES);
GraphiteReporter.enable(1, TimeUnit.MINUTES, "my.host.name", 2003);
}
@Override
protected void doGet(final HttpServletRequest req,
final HttpServletResponse resp) throws ServletException,
IOException {
final TimerContext timerContext = Metrics.newMeter(CreateSessionServlet.class,"myservlet-meter", "requests", TimeUnit.SECONDS).time();
try {
...
} finally {
timerContext.stop();
}
with spring annotations and codahale metrics as mentioned here?
I thought it would be as simple as:
-annotating my servlet like this (I will need gauges and metering eventually):
@Timed
@Gauge
@Metered
@Override
protected void doGet(final HttpServletRequest req,
final HttpServletResponse resp) throws ServletException, IOException {
-and updating my spring-servlet to enable the spring annotations as explained on the page mentioned above.
But when I use jconsole, I do not see in the MBeans section any additional entry for that servlet that I instrumented than for other servlets that do not use any annotation
So my two questions:
Is there anything I am missing so that my web app actually sends metric data via JMX?
If I want the code with spring annotations to start reporting to a CSV file or to graphite, what do I need to add?
Surprisingly I found no complete examples on the web or in the doc from codahale on this.
