I am trying to get Cassandra metrics through logstash jmx input. My logstash pipeline conf:
```auto
/etc/logstash/conf.d/cassandra_jmx.conf
input {
jmx {
path => "/etc/logstash/jmxconf"
polling_frequency => 15
type => "jmx"
nb_thread => 4
}
}
output {
elasticsearch {
hosts => [":9200"]
user => "myuser"
password => "mypass"
}
}
```
/etc/logstash/jmxconf/jmx\_config.json :
```auto
{
"host" : "my-cassandra-node",
"port" : 7199,
"username" : "my_jmx_user",
"password": "my_jmx_pass",
"alias" : "test.homeserver.elasticsearch",
"queries" : [{
"object_name" : "org.apache.cassandra.metrics:type=ThreadPools,path=request,scope=RequestResponseStage,name=*",
"object_alias" : "${type}.${path}.${scope}.${name}"
}, {
"object_name" : "java.lang:type=Threading",
"object_alias" : "Threading"
}, {
"object_name" : "java.lang:type=Runtime",
"attributes" : ["Uptime", "StartTime"],
"object_alias" : "Runtime"
}]
}
```
Logstash logs:

What is your question?

The question is why this info logs continue indefinitely?

The main run function sits in a loop loading the configuration, logging this message, and calling thread\_jmx. The thread\_jmx [function](https://github.com/logstash-plugins/logstash-input-jmx/blob/10b465fce60726958e2fb4fa3e59722d222ded39/lib/logstash/inputs/jmx.rb#L201) also loops. If you enable log.level debug it should be a lot easier to determine what path the code is taking.

I think you can use Jolokia to extract the metrics of Cassandra to the Rest API and run the metricbeat agent with enable jolokia module.
