This project is originally a fork of JMX exporter but aims at an easier integration with Apache Cassandra®. Next, you can add a monitoring chart to display the JVM indicator line:in the JAVA service componentĬlick above the business monitoring panel to add chartĪfter entering a new title and the corresponding query condition jvm_memory_bytes_used, click to query.If the chart is returned normally, the query conditions are correct.The definition of the title should be as clear and concise as possible, and the unit should be specified where necessary. Cassandra exporter is a standalone application which exports Apache Cassandra® metrics throught a prometheus friendly endpoint.
#Prometheus jmx exporter update#
Add application monitoring point Īpplication monitoring is based on rbd-monitor When we add monitoring points, it is equivalent to creating a servicemonitor.Įnter the component -> monitoring -> business monitoring -> management monitoring point, add monitoring point, fill in the following information:Īfter adding, update the component to make it take effect. The last update component will take effect. It provides a component called the JMX Exporter that can be used to gather data from MBeans of a JMX target. In the port management of the component, add a new port 5556 Prometheus is an open-source monitoring tool.

The mountable configuration file /tmp/agent/prometheus-jmx-config.yaml replaces the existing configuration file. Through the shared storage, the initialization plug-in puts the required configuration files and Agent in the shared storage for the main service to use, so as to realize the service without intrusion.Īdd environment variable for JAVA service component JAVA_OPTS = -javaagent:/tmp/agent/jmx_prometheus_javaagent-0.16.1.jar=5556:/tmp/agent/prometheus-jmx-config.yaml Mount storage /tmp/agentfor the JAVA service component so that it can share storage with plugins. You can refer to: Rainbond integrates SkyWalking through plug-ins to realize APM plug-and-play Agent plug-in implementation principle part.Įnter the team -> plugins -> create a new plugin, create an initialization type plugin, source address: Īfter the plug-in is successfully constructed, it can be used, and this plug-in can be activated for the JAVA service component. The implementation principle has been explained in detail in previous articles.
#Prometheus jmx exporter code#
JAVA applications built from Rainbond source code since V5.3 will be packaged with JMX Exporter by default, and users only need to add environment variables to enable them.Īdd a specified environment variable ES_ENABLE_JMX_EXPORTER = true for the JAVA service component to enable jmx_exporter.Īdd a port 5556 to the port management of the JAVA service component, which is the default port that jmx_exporter listens on.įor mirrored or market-built apps, you can inject jmx_agentusing an initialization type of plugin.

On Rainbond, components with different build types are handled differently, as follows

Officially, it is not recommended to use to start an independent process This method is complicated to configure and requires a separate process, and the monitoring of the process itself has caused new problems.This article takes the JVM in-process (in-process)method as an example, and uses the JMX Exporter in Rainbond to expose the JVM monitoring indicators. Specify parameters when the JVM starts, run the JMX Exporter jar package in the form of javaagent, read the JVM runtime status data in the process, convert it to the Prometheus metrics format, and expose the port for Prometheus to collect.

The parameters are specified when the JVM starts, and the RMI interface of JMX is exposed.JMX Exporter calls RMI to obtain JVM runtime status data, converts it to Prometheus metrics format, and exposes ports for Prometheus to collect. JMX Exporter provides start independent process and JVM in-process start (in:process)two ways to expose JVM monitoring indicators4 For Linux see below wget https: // / remotecontent filepath io / prometheus / jmx / jmxprometheusjavaagent / 0.13.0 / jmxprometheusjavaagent-0.13.0. Java Management Extensions, JMX is an extension framework for managing Java, JMX Exporter reads the runtime state of the JVM based on this framework.JMX Exporter uses Java's JMX mechanism to read the monitoring data of the JVM runtime, and then converts it into a metrics format that can be recognized by Prometheus, so that Prometheus can monitor and collect it. Step 1 JMX exporter can be downloaded easily via the maven repo. # irate(process_cpu_seconds_total 0.Learn how Java applications deployed on Rainbond can use the JMX Exporter to expose JVM monitoring metrics.
