Ingredients:
- ElasticSearch 1.4.0
- Logstash 1.4.2
- Kibana 3.1.2
- JBoss EAP 6.2
After having gone throught the downloading and installation process first we need to extract some libs out of the modules for JBoss EAP 6.2 that are needed for getting remote JMX calls to work.
In elastic-search-1.4.0/vendor/bundle/jruby/1.9/gems/jmx4r-0.1.4/lib create a file jboss_remoting.rb
module JMX
module JBoss
java_import java.lang.System
class JBossRemoting
sep = System.get_property 'file.separator'
home = System.get_property 'jboss.home'
if home != nil
modulebase = [home, 'modules','system','layers','base','org','jboss'].join(sep)
libs = [
['remoting-jmx','main'],
['remoting3','main'],
['logging','main'],
['xnio','main'],
['xnio','nio','main'],
['sasl','main'],
['marshalling','main'],
['marshalling','river','main'],
['as','cli','main'],
['staxmapper','main'],
['as','protocol','main'],
['dmr','main'],
['as','controller-client','main'],
['threads','main']
]
for index in 0 ... libs.size
Dir[modulebase + sep + libs[index].join(sep) + sep + "*.jar"].each {|file| require file }
end
end
end
end
end
In elastic-search-1.4.0/vendor/bundle/jruby/1.9/gems/jmx4r-0.1.4/lib/jmx4r.rb after
require 'jruby'
add
require 'jboss_remoting'In logstash-1.4.2/config/logstash.conf I created the following configuration
input {
jmx{
path => "logstash-1.4.2/jmx"
polling_frequency => 30
type => "jmx"
nb_thread => 4
}
}
output {
elasticsearch { host => localhost }
}
and in logstash-1.4.2/jmx/jmx.conf I configured
{
// JBoss Remoting JMX URL
"url" : "service:jmx:remoting-jmx://localhost:9999",
//username to connect to jmx
"username" : "<your-user>",
//password to connect to jmx
"password": "<your-password>",
"alias" : "jmx.instance1.elasticsearch",
//List of JMX metrics to retrieve
"queries" : [
{
"object_name" : "java.lang:type=Memory",
"attributes" : [ "HeapMemoryUsage", "NonHeapMemoryUsage" ],
"object_alias" : "Memory"
}, {
"object_name" : "java.lang:type=Runtime",
"attributes" : [ "Uptime", "StartTime" ],
"object_alias" : "Runtime"
}, {
"object_name" : "java.lang:type=Threading",
"attributes" : [ "ThreadCount", "TotalStartedThreadCount", "DaemonThreadCount", "PeakThreadCount" ],
"object_alias" : "Threading"
}, {
"object_name" : "java.lang:type=OperatingSystem",
"attributes" : [ "OpenFileDescriptorCount", "FreePhysicalMemorySize", "CommittedVirtualMemorySize", "FreeSwapSpaceSize", "ProcessCpuLoad", "ProcessCpuTime", "SystemCpuLoad", "TotalPhysicalMemorySize", "TotalSwapSpaceSize", "SystemLoadAverage" ],
"object_alias" : "OperatingSystem"
} ]
}
As the original JMX input plugin only supports configuration via host and port you need to apply the pull request 141 (https://github.com/elasticsearch/logstash-contrib/pull/141) to your local installation, i.e. by downloading https://raw.githubusercontent.com/jcordes73/logstash-contrib/master/lib/logstash/inputs/jmx.rb and save it to logstash-1.4.2/lib/logstash/inputs
Now you need to setup a JBoss management user via jboss-eap-6.2/bin/add-user.sh to reflect the username and password defined in jmx.conf above.
Because of a change in behaviour in regards to security you need to add the following configuration to elasticsearch-1.4.0/config/elasticsearch.yml
http.cors.enabled: trueand also change http.enabled to true.
http.cors.allow-origin: "*"
We need to set some environment variables so that the JBoss Remoting libraries can be found from an existing JBoss EAP installation:
JBOSS_HOME=/opt/jboss-eap-6.2Now you can start ElasticSearch via elasticsearch-1.4.0/bin/elasticsearch and logstash via logstash-1.4.2/bin/logstash -f logstash-1.4.2/config/logstash.conf.
export JBOSS_HOME
JAVA_OPTS="-Djboss.home=$JBOSS_HOME"
export JAVA_OPTS
To finally see your JMX data via Kibana, open kibana-3.1.2/index.html with your favourite web-browser.
