Hello to everyone!  
I downloaded`jolokia-jvm-1.5.0-agent.jar` and made command `java -javaagent:/path/to/jolokia-jvm-<version>-agent.jar start [processId]`. And it started.

```
- module: jolokia
  metricsets: ["jmx"]
  enabled: true
  period: 10s
  hosts: ["localhost:8778"]
  namespace: "metrics"
  path: "/jolokia/?ignoreErrors=true&canonicalNaming=false"
  jmx.mappings:
       - mbean: 'java.lang:type=Memory'
         attributes:
           - attr: HeapMemoryUsagePercent
             field: memory.heap_usage_pct
             field_type: integer
           - attr: NonHeapMemoryUsage
             field: memory.non_heap_usage
             field_type: integer
jmx.application:
jmx.instance:

```

When I restart metricbeat service, I get normal log without any exception. But when metrics start to be collecting by metricbeat futher in log, I see string `jolokia:["jmx";{"events":3,"failures":3}}`  
In Kibana I've not found any metrics with name `memory.heap_usage_pct` or `memory.non_heap_usage`  
What I am doing wrong?

Can you see more errors in the logs? What version of metricbeat are you using?

`jolokia:["jmx";{"events":3,"failures":3}}` I found in `non-zero metrics`
