I have a spring-boot - dropwizard hello world application. The following is a print-screen from jvisualvm of the application ... ![Untitled](https://us1.discourse-cdn.com/elastic/original/3X/7/e/7ebfb296ea068ccb01744bcc473cba335618e387.png) This is also what I can see from [http://localhost:8080/metrics](http://localhost:8080/metrics) in a browser: ``` { "mem" : 467911, "mem.free" : 306671, "processors" : 8, "instance.uptime" : 5639045, "uptime" : 5643416, "systemload.average" : -1.0, "heap.committed" : 409088, "heap.init" : 262144, "heap.used" : 102416, "heap" : 3706880, "nonheap.committed" : 60184, "nonheap.init" : 2496, "nonheap.used" : 58823, "nonheap" : 0, "threads.peak" : 40, "threads.daemon" : 28, "threads.totalStarted" : 63, "threads" : 31, "classes" : 7965, "classes.loaded" : 7965, "classes.unloaded" : 0, "gc.ps_scavenge.count" : 14, "gc.ps_scavenge.time" : 224, "gc.ps_marksweep.count" : 2, "gc.ps_marksweep.time" : 75, "com.example.SimpleServiceDelegate.sayHello.snapshot.98thPercentile" : 0, "com.example.SimpleServiceDelegate.doSomething.exceptions.count" : 0, "com.example.SimpleServiceDelegate.doSomething.snapshot.999thPercentile" : 0, "com.example.SimpleServiceDelegate.doSomething.exceptions.oneMinuteRate" : 0.0, "gauge.response.star-star.favicon.ico" : 26.0, "com.example.SimpleServiceDelegate.sayHello.exceptions.oneMinuteRate" : 0.0, "com.example.SimpleServiceDelegate.doSomething.snapshot.min" : 0, "com.example.SimpleServiceDelegate.sayHello.exceptions.fiveMinuteRate" : 0.0, "com.example.SimpleServiceDelegate.doSomething.snapshot.95thPercentile" : 0, "com.example.SimpleServiceDelegate.sayHello.oneMinuteRate" : 0.0, "com.example.SimpleServiceDelegate.doSomething.snapshot.98thPercentile" : 0, "com.example.SimpleServiceDelegate.doSomething.snapshot.median" : 0, "gauge.response.metrics.name" : 0.0, "com.example.SimpleServiceDelegate.sayHello.snapshot.75thPercentile" : 0, "counter.status.404.star-star" : 2, "gauge.response.metrics" : 1.0, "com.example.SimpleServiceDelegate.sayHello.snapshot.median" : 0, "com.example.SimpleServiceDelegate.sayHello.fifteenMinuteRate" : 0.0, "com.example.SimpleServiceDelegate.sayHello.exceptions.count" : 0, "com.example.SimpleServiceDelegate.doSomething.snapshot.mean" : 0, "com.example.SimpleServiceDelegate.doSomething.meanRate" : 0.0, "com.example.SimpleServiceDelegate.sayHello.snapshot.min" : 0, "com.example.SimpleServiceDelegate.sayHello.exceptions.meanRate" : 0.0, "com.example.SimpleServiceDelegate.sayHello.exceptions.fifteenMinuteRate" : 0.0, "counter.status.200.star-star.favicon.ico" : 1, "com.example.SimpleServiceDelegate.doSomething.snapshot.max" : 0, "com.example.SimpleServiceDelegate.sayHello.count" : 0, "com.example.SimpleServiceDelegate.sayHello.snapshot.stdDev" : 0, "com.example.SimpleServiceDelegate.sayHello.fiveMinuteRate" : 0.0, "counter.status.200.metrics" : 2405, "com.example.SimpleServiceDelegate.doSomething.snapshot.75thPercentile" : 0, "counter.status.404.metrics.name" : 3268, "com.example.SimpleServiceDelegate.doSomething.fifteenMinuteRate" : 0.0, "com.example.SimpleServiceDelegate.sayHello.snapshot.max" : 0, "com.example.SimpleServiceDelegate.doSomething.exceptions.meanRate" : 0.0, "com.example.SimpleServiceDelegate.sayHello.snapshot.95thPercentile" : 0, "com.example.SimpleServiceDelegate.sayHello.snapshot.999thPercentile" : 0, "com.example.SimpleServiceDelegate.doSomething.count" : 0, "com.example.SimpleServiceDelegate.sayHello.snapshot.mean" : 0, "gauge.response.star-star" : 1.0, "com.example.SimpleServiceDelegate.doSomething.oneMinuteRate" : 0.0, "com.example.SimpleServiceDelegate.doSomething.snapshot.99thPercentile" : 0, "com.example.SimpleServiceDelegate.doSomething.fiveMinuteRate" : 0.0, "com.example.SimpleServiceDelegate.sayHello.snapshot.99thPercentile" : 0, "com.example.SimpleServiceDelegate.sayHello.meanRate" : 0.0, "com.example.SimpleServiceDelegate.doSomething.exceptions.fiveMinuteRate" : 0.0, "com.example.SimpleServiceDelegate.doSomething.exceptions.fifteenMinuteRate" : 0.0, "com.example.SimpleServiceDelegate.doSomething.snapshot.stdDev" : 0, "httpsessions.max" : -1, "httpsessions.active" : 0 } ``` My metricbeat.yml includes this configuration: ``` #----------------------------- Dropwizard Module ----------------------------- - module: dropwizard metricsets: ["collector"] period: 2s hosts: ["localhost:8080"] metrics_path: /metrics/metrics namespace: example enabled: true ``` With this configuration I can't get any data from the application. Since there is no description for `metrics_path` and `namespace` in [elastic's website](https://www.elastic.co/guide/en/beats/metricbeat/master/metricbeat-module-dropwizard.html), I tested many things for these two parameters but with no success ☹ for example when I use > metrics\_path: /metrics/com/example/SimpleServiceDelegate/doSomething/Count > namespace: example I get `HTTP error 404 in collector: 404` in `error.message` field with no useful hint from DEBUG level logs. Any help will be appreciated. ---

Hi, That error seems to reflect a page not found when accessing the given path: > [@Ilia](#): > > metrics\_path: /metrics/metrics Have you tried with `metrics_path: /metrics`? ---

Hi, Thank you for reply > [@exekias](#): > > Have you tried with `metrics_path: /metrics` ? Yes. Actually when I set `metrics_path: /metrics` I don't get any response, even no error, but when I set `metrics_path: /metrics/metrics` I get `HTTP error 404 in collector: 404` error. After posting this question I got suspected to `namespace` that if this is something related to dropwizard? Searching a bit about it I found [another helloworld](https://github.com/Appdynamics/dropwizard-sample-app) that `namespace` is used [somewhere](https://github.com/Appdynamics/dropwizard-sample-app/blob/master/src/main/java/com/example/helloworld/cli/RenderCommand.java#L33) in its code. When I run it I can get messages with this configuration: ``` - module: dropwizard metricsets: ["collector"] period: 2s hosts: ["localhost:8083"] metrics_path: /metrics namespace: names enabled: true ``` But I don't think `namespace: names` made any effect, because when I change it to any other string like `namespace: zzzzzz` I can yet get message with this pattern: `dropwizard.zzzzzz.*`. So, it seems that `namespace` is something related to `metricbeat` (to categorize messages) not `dropwizard`!! Another problem is that using the above configuration the `collector` metricset collects all metric stuffs from all tools in the apllcation, even from logback and jvm, for example. ``` { "_index": "myapp-metrics-2018.09.03", "_type": "doc", "_id": "zcCLn2UB1q2w-uLb3qwo", "_version": 1, "_score": null, "_source": { "@version": "1", "dropwizard": { "zzzzzz": { "jvm.gc.PS-MarkSweep.count": { "value": 2 }, "jvm.memory.heap.committed": { "value": 330825728 }, "jvm.memory.total.committed": { "value": 383016960 }, "com.codahale.dropwizard.jetty.MutableServletContextHandler.5xx-responses": { "count": 0, "m1_rate": 0, "units": "events/second", "m15_rate": 0, "m5_rate": 0, "mean_rate": 0 }, "org.eclipse.jetty.server.HttpConnectionFactory.8082.connections": { "p99": 0, "count": 0, "m1_rate": 0, "p95": 0, "stddev": 0, "m15_rate": 0, "m5_rate": 0, "p50": 0, "mean_rate": 0, "p999": 0, "p98": 0, "max": 0, "min": 0, "duration_units": "seconds", "mean": 0, "rate_units": "calls/second", "p75": 0 }, "com.example.helloworld.resources.HelloWorldResource.get-requests": { "p99": 0, "m1_rate": 0, "count": 0, "p95": 0, "p999": 0, "m15_rate": 0, "stddev": 0, "p50": 0, "mean_rate": 0, "m5_rate": 0, "p98": 0, "max": 0, "min": 0, "duration_units": "seconds", "mean": 0, "rate_units": "calls/second", "p75": 0 }, "ch.qos.logback.core.Appender.all": { "count": 25, "m1_rate": 4.600222073146615, "units": "events/second", "m15_rate": 1.4325239843009516, "m5_rate": 3.8940039153570245, "mean_rate": 0.29945654457636356 }, "jvm.memory.non-heap.usage": { "value": -51127984 }, "org.eclipse.jetty.util.thread.QueuedThreadPool.dw.utilization": { "value": 0.96 }, "ch.qos.logback.core.Appender.error": { "count": 0, "m1_rate": 0, "units": "events/second", "m15_rate": 0, "m5_rate": 0, "mean_rate": 0 }, "jvm.gc.PS-MarkSweep.time": { "value": 78 }, "jvm.memory.heap.init": { "value": 268435456 }, "jvm.threads.runnable.count": { "value": 40 }, "jvm.memory.pools.Code-Cache.usage": { "value": 0.03833847045898438 }, "jvm.buffers.direct.used": { "value": 40491 }, "jvm.memory.heap.used": { "value": 29903632 }, "jvm.threads.terminated.count": { "value": 0 }, "com.codahale.dropwizard.jetty.MutableServletContextHandler.active-dispatches": { "count": 0 }, "jvm.memory.total.max": { "value": 3795845119 }, "jvm.threads.blocked.count": { "value": 12 }, "jvm.memory.non-heap.init": { "value": 2555904 }, "jvm.memory.non-heap.used": { "value": 51127984 } ............................. and many more! } }, "host": { "name": "UI" }, "beat": { "hostname": "UI", "name": "UI", "version": "6.4.0" }, "@timestamp": "2018-09-03T13:07:47.271Z", "fields": { "app": "myapp-core", "type": "metrics" }, "metricset": { "name": "collector", "module": "dropwizard", "namespace": "dropwizard.zzzzzz", "rtt": 9024, "host": "localhost:8083" } }, "fields": { "@timestamp": [ "2018-09-03T13:07:47.271Z" ] }, "sort": [ 1535980067271 ] } ``` I know I can filter/delete extra fields in `logstash` but sending a lot of unnecessary messages increases network band usage. Is there any way to get metrics only from some special classes, only from `com.example.helloworld.resources.HelloWorldResource` class or its `sayHello` method in this application, for example? ---
