Jmx metrics using logstash jmx input plugin

Elastic Stack Logstash
1

Hello team
I have installed jmx plugin to logstash 6.6.2
How do this plugin work. When I start the logstash with jmx input and jmx config as the input file.....It is giving an error....no such file or directory found.

Input
{
jmx {
//Required
path => "/apps/logstash_conf/jmxconf"
//Optional, default 60s
polling_frequency => 15
type => "jmx"
//Optional, default 4
nb_thread => 4
}
}
Output
{
elasticsearch {
host......
Index..
}

}

Jmx conf file

{
//Required, JMX listening host/ip
"host" : "192.168.1.2",
//Required, JMX listening port
"port" : 1335,
//Optional, the username to connect to JMX
"username" : "user",
//Optional, the password to connect to JMX
"password": "pass",
//Optional, use this alias as a prefix in the metric name. If not set use _
"alias" : "test.homeserver.elasticsearch",
//Required, list of JMX metrics to retrieve
"queries" : [
{
//Required, the object name of Mbean to request
"object_name" : "java.lang:type=Memory",
//Optional, use this alias in the metrics value instead of the object_name
"object_alias" : "Memory"
}, {
"object_name" : "java.lang:type=Runtime",
//Optional, set of attributes to retrieve. If not set retrieve
//all metrics available on the configured object_name.
"attributes" : [ "Uptime", "StartTime" ],
"object_alias" : "Runtime"
}, {
//object_name can be configured with * to retrieve all matching Mbeans
"object_name" : "java.lang:type=GarbageCollector,name=",
"attributes" : [ "CollectionCount", "CollectionTime" ],
//object_alias can be based on specific value from the object_name thanks to {<varname>}. //In this case {type} will be replaced by GarbageCollector...
"object_alias" : "{type}.{name}"
}, {
"object_name" : "java.nio:type=BufferPool,name=",
"object_alias" : "{type}.{name}"
} ]
}

I am unable to understand why it would be looking for that file given the configuration you claim to be running.
