Metricbeat jolokia agent for tomcat application

I'm contacting you about collecting metrics for a java tomcat application.
We want to collect metrics for our application and we need to put it on the ELK stack for graphing !!

here below many config :

==> on my tomcat server : 

-- jolokia running on port 8778
-- jolokia.yml :

  • module: jolokia
    metricsets: ["jmx"]
    hosts: ["localhost:8778"]
    period: 10s
    namespace: "jvm"
    • mbean: "java.lang:type=Memory"
      • attr: "HeapMemoryUsage"
        field: "memory.heap"
      • attr: "NonHeapMemoryUsage"
        field: "memory.nonheap"
    • mbean: "java.lang:type=Threading"
      • attr: "ThreadCount"
        field: "thread.count"
        event: threads
      • attr: "DaemonThreadCount"
        field: "thread.daemon"
        event: threads

-- metricbeat.yml :

hosts: ["server_elastic:9200"]

the question is, we have to create a configuration on logstash? pipelines for example? or is the output to elasticsearch enough?

Thank you for your answer



You do not need to create a LogStash pipeline for this usecase. MetricBeat will send the data in the correct form to ElasticSearch so you do not need to parse anything.

Best regards

okey i see
but with my configuration i have to restart services and it will work ?

many thanks


It should work, yes.

@Wolfram_Haussig thanks for replying !!
do you know how to get dashboard on kibana ? should i create it ?
i can't get graphing for JMX on kibana !!!


note that i have not restart elk stack
and on my metricbeat machine log i see :

Hi Sai,

As the jolokia module can be widely configured and changed to fit the customers needs it would be hard - or even impossible - do create a dashboard for the customers.

I think the tomcat module of metricbeat - which is still in BETA - will get a dashboard as soon as it is GA as this has a defined set of metrics which can only be enabled or disabled...

So for now, you would have to create your own dashboards.

Best regards

ok thanks ,
but when i would create new dashboard in kibana i can't get jmx (spacename) !!


Hi @Wolfram_Haussig
Here below my conf in logstash server pipelines.yml:
- pipeline_metrics
path.config: "/opt/logstash/config/conf.d/pipeline_metrics.conf"

    input {

beats {
port => 5044

output {
elasticsearch {
hosts => ["http://localhost:9200"]
index => "%{[@metadata][beat]}-%{[@metadata][metricbeat-7.6.0]}"

my probleme i don't have any entries in elk stack :confused:


Why are you using LogStash for this case? I think that the data is being written to the wrong index or it is not written at all. I would recommend that you configure MetricBeat to write directly to ElasticSearch. If this is not possible please check that:

  • does the logstash log show any errors?
  • if you have monitoring enabled please check if the pipeline is receiving and sending data
  • check in Kibana if you can see the correct index being created and written to

Best regards
