I am writing an app in pure Java without using Spring/SpringBoot or any other frameworks. I am using the TICK stack (Telegraf, Influx, Chronograf, and Kapacitor) as my metrics backend and viz platform. I am using Telegraf with Statsd plugin activated on localhost 8125. The problem is that my app is not sending any metrics to the system. However, I wrote a simple Spring Boot app which pushed the relevant metrics to my dashboard. Also, doing an echo "api.msgs.ok:10|c" | nc -C -w 1 -u localhost 8125
pushes the metrics to my dashboard as well.
The sample code I am trying to run is here:
import io.micrometer.statsd.StatsdConfig;
import io.micrometer.statsd.StatsdFlavor;
import io.micrometer.statsd.StatsdMeterRegistry;
import java.util.Properties;
public class TestMicrometer {
public static void main(String[] args) throws InterruptedException{
Properties properties = new Properties();
//properties.put("statsd.host","127.0.0.1");
//properties.put("statsd.port","8125");
StatsdConfig config = new StatsdConfig() {
//Will use localhost 8125 if get returns null always
@Override
public String get(String k) {
/*
System.out.println("Key " +k+ " is called");
if (k.equals("statsd.host")){
System.out.println("The host is "+properties.getProperty(k));
}
return properties.getProperty(k);
*/
return null;
}
@Override
public StatsdFlavor flavor() {
return StatsdFlavor.TELEGRAF;
}
};
MeterRegistry registry = new StatsdMeterRegistry(config, Clock.SYSTEM);
Counter.builder("loop.counter.test").description("TOTAL_LOOP_COUNTER").tags("LOOP.COUNTER","SAMPLE.LOOP.METER").register(registry).increment();
Metrics.addRegistry(registry);
for (int i = 0; i < 50; i++) {
Metrics.counter("loop.counter.test").increment();
}
}
}
Any help will be highly appreciated :)
Publishing of StatsD metrics is asynchronous, and this example simply terminates too quickly. Put a Thread.sleep(1000)
at the end, and metrics are published fine.
