To enable it, you move the $IGNTE_HOME/libs/optional/ignite-opencensus folder up a level (to $IGNITE_HOME/libs). Indeed, we use OpenCensus in our Control Center monitoring and management tool.īefore you can use Open Census, you must enable it. Our commitment to open standards and open source led GridGain to implement OpenCensus support in Apache Ignite too. OpenCensus is a cross-platform metrics and tracing format that Prometheus supports natively. Viewing Apache Ignite Metrics via OpenCensus So, although you can employ JMX beans to use Prometheus with Apache Ignite, you might find a few wrinkles. For the connection to work successfully, I needed to do some additional error handling. After the last release of the exporter, a fix was merged to the master branch. The updates caused Prometheus to not understand the format of some JMX beans. In Apache Ignite 2.8.x, significant updates were made to metrics reporting. One last thing about using the JMX Exporter: The process works correctly only with versions of GridGain and Apache Ignite that are earlier than version 2.7.x. You point the exporter at the JMX port of your Apache Ignite or GridGain node. If you use the server, you need to add the “hostPort” parameter to your JMX Exporter configuration. $ bin/ignite.sh -v $PROJECT/config/myconfig.xml -J-javaagent:$MYLIBS/jmx_prometheus_javaagent-0.14.0.jar=9000:$PROJECT/config/prometheus.ymlĪlternatively, you can use the jmx_prometheus_httpserver server. You can then run the JMX Exporter as a Java agent: Prometheus has a JMX Exporter that you can use as a bridge between Prometheus and GridGain. JMX is a Java standard for viewing the metrics of a running JVM. Because Prometheus is a Java application, people often look first at Apache Ignite’s JMX beans. targets: Viewing Apache Ignite Metrics via JMXĪfter Prometheus is up and running, we need an exporter to send metrics data to be visualized. The default is 1 minute.Įvaluation_interval: 15s # Evaluate the rules every 15 seconds. Scrape_interval: 15s # Set the scrape interval to 15 seconds. I added a couple of scrape configs, which reference two Apache Ignite nodes that run on my local machine. I prefer that my metrics update more frequently than once per minute, although a more frequent interval is not required. I use the following configuration for the rest of this article.įirst, I made the scrape interval more frequent. This post isn’t about how best to configure Prometheus, so we’ll use the defaults as much as we can. This post provides hints about how to integrate Prometheus with Apache Ignite and GridGain. We often see Apache Ignite and GridGain users trying to integrate Prometheus with their clusters. Prometheus is a popular monitoring tool that is supported by the Cloud Native Computing Foundation, the group who support Kubernetes. ![]()
