![]() Finally, Grafana is an open-source visualization tool which works nicely with several time series databases, such as Prometheus. JMX managed resources are called Managed Beans (MBeans), and these can expose information about HBase’s status for us. Java Management Extensions, is a set of tools for connecting to a JVM and managing resources at runtime. If you’re running a JVM-based application but there’s no dedicated exporter, then the JMX exporter can be used for exposing JMX MBeans in the Prometheus metric format. It uses a pull-model over HTTP to continuously fetch metrics and features several out-of-the-box exporters for several systems. I find it very easy to set up, manage and collect metrics. Prometheus is an open-source time series database system for collecting system metrics. I’m running a pseudo-distributed HBase with 2 masters and 4 regionservers in this post. We will monitor HBase using three tools: (1) Prometheus’ JMX exporter for exporting HBase’s JMX metrics, (2) Prometheus for storing metrics and (3) Grafana for visualizing the metrics. In this blog post I will show how to get started with Prometheus‘ JMX exporter, exporting the HBase metrics and visualizing them in Grafana. It comes with a management UI showing table details, but I wanted a better understanding of the internals of HBase.
