					<description><![CDATA[You may have come across a mBean attribute with a value such as STARTED or RUNNING. How do you convert that to a more useful boolean metric? In Exposing version numbers with the JMX exporter you saw how you could expose a version number that was the string value of an mBean attribute as a label [&#8230;]]]></description>

					<description><![CDATA[While the JMX attributes you are usually working with will be numbers, the JMX exporter also has support for strings. The JMX exporter automatically handles mBean attributes with numeric and boolean values. You will however sometimes come across string attributes that are of interest, such as version numbers. While these aren't exposed out of the [&#8230;]]]></description>

					<description><![CDATA[We've previously looked at how to monitor Cassandra with Prometheus. Let's see the process for getting metrics from another popular Java application, Kafka. Similar to what we did for Cassandra, we download Kafka, the JMX exporter and the config file: wget http://ftp.heanet.ie/mirrors/www.apache.org/dist/kafka/1.0.0/kafka_2.11-1.0.0.tgz tar -xzf kafka_*.tgz cd kafka_* wget https://repo1.maven.org/maven2/io/prometheus/jmx/jmx_prometheus_javaagent/0.6/jmx_prometheus_javaagent-0.6.jar wget https://raw.githubusercontent.com/prometheus/jmx_exporter/master/example_configs/kafka-0-8-2.yml We start a Zookeeper (a Kafka dependency) [&#8230;]]]></description>

					<description><![CDATA[Cassandra is one of many Java-based systems that offers metrics via JMX. The JMX Exporter offers way to use these with Prometheus. By following these steps you can be up and running in under a minute! We'll start from scratch, first we download and extract the latest Cassandra tarball: wget http://archive.apache.org/dist/cassandra/2.2.4/apache-cassandra-2.2.4-bin.tar.gz tar -xzf apache-cassandra-*-bin.tar.gz cd apache-cassandra-* [&#8230;]]]></description>

					<description><![CDATA[Sometimes mBeans produce errors when scraped by the JMX exporter. Being able to look at detailed logs can help you figure out exactly which mBean is having issues and why. Create a file called logging.properties with this content: handlers=java.util.logging.ConsoleHandler java.util.logging.ConsoleHandler.level=ALL io.prometheus.jmx.level=ALL io.prometheus.jmx.shaded.io.prometheus.jmx.level=ALL Add the following flag to your Java invocation: -Djava.util.logging.config.file=/path/to/logging.properties If you run your [&#8230;]]]></description>
