I had a working setup with cassandra + jmx + jolokia + metricbeat not too long ago. Lately Im only getting the message : "HTTP Error 404 in jmx: 404 not found". Presently runnign 6.4. Have tried downgrading to 6.3 to no avail.

What Ive tested:

- I can get jmx metrics using the jmx cli
- I can get jolokia values using curl

All that leaves is the metric beat module.

Suggestions on where Ive gone wrong?

---- EDIT:

jolokia.yml:

- module: jolokia  
metricsets: ["jmx"]  
hosts: ["localhost:7770"]  
namespace: "jmxmetrics"  
jmx.mappings:

    - attr: Value  
field: compaction.pending\_tasks

After a dive into the metricbeat code and subsequent experiments with curl POST requests Im thinking this might be a jolokia issue after all. jolokia works fine with GET requests but not POST.

Im switching to an HTTP module instead. Seems to be working ok --\> and --\> it takes wildcards!

Hi @ethrbunny 🙂

Jolokia modules uses POST as you can see in the following line: [https://github.com/elastic/beats/blob/master/metricbeat/module/jolokia/jmx/jmx.go#L83](https://github.com/elastic/beats/blob/master/metricbeat/module/jolokia/jmx/jmx.go#L83)

Did you have problems by doing curl and POST on Jolokia? Please, can you develop a bit? If it's an issue with the module we'll try to fix it to help the community 🙂 Even better, we encourage you to fix it if you feel that you understand the root of the problem 🙂

I was unable to get POST to work with jolokia. Are there some _specific_ examples of curl usage so I can make sure Im doing it correctly?

In any event the 'http/json' module is a good replacement.

Hi! I have the same problem. This configuration was working with v6.2.4 until I upgraded to v6.4.0:

```
- module: jolokia
  metricsets: ["jmx"]
  enabled: true
  period: 30s
  namespace: "java_jmx"
  hosts: ["localhost:8778"]
  jmx.mappings:
  - mbean: 'org.apache.cassandra.metrics:name=HitRate,scope=KeyCache,type=Cache'
    attributes:
    - attr: Value
      field: key_cache.hit_rate

```

I've been able to make a POST with curl with the body that I've found in the logs:  
`curl --header "Content-Type: application/json" --request POST --data '{"type":"read","mbean":"org.apache.cassandra.metrics:name=HitRate,scope=KeyCache,type=Cache","attribute":["Value"],"config":{"canonicalNaming":true,"ignoreErrors":true}}' http://localhost:8778/jolokia/`

`{"request":{"mbean":"org.apache.cassandra.metrics:name=HitRate,scope=KeyCache,type=Cache","attribute":"Value","type":"read"},"value":{"Value":0.9983935115946554},"timestamp":1538180662,"status":200}`

Fixed! I had to add the /jolokia/ path to the host:

```auto
- module: jolokia
  metricsets: ["jmx"]
  enabled: true
  period: 30s
  namespace: "java_jmx"
  hosts: ["localhost:8778/jolokia/"]
  jmx.mappings:
  - mbean: 'org.apache.cassandra.metrics:name=HitRate,scope=KeyCache,type=Cache'
    attributes:
    - attr: Value
      field: key_cache.hit_rate

```

Thanks for posting the solution here.
