![]() ![]() Once the Prometheus and Grafana servers are installed, you can enable support in the Tungsten Dashboard Settings panel. We’ve made it easy to access and view your Prometheus/Grafana monitoring implementation inside the Tungsten Dashboard. If you’re using the Tungsten Dashboard GUI to manage your Tungsten Clusters, you might want to integrate your monitoring solution into that so the monitoring and management of your clusters exist all in one place. In the Dashboard field, enter 12760 for the Continuent Tungsten Dashboard, then click “Load.” Tungsten Dashboard Integration Click the “Import” link to the right of the green “New Dashboard” button. In the Grafana GUI, hover over the Dashboards icon in the left navigation bar, then select “Manage” from the sub-menu. In the mysql-exporter.cnf file, include the following lines to route to the. It displays specific Metrics in Panels, and it displays groups of Panels in Dashboards.Ĭontinuent has created a custom, downloadable dashboard for Grafana. MySQL Mysql Slave Replication Lag, MySQL Slave replication lag, Prometheus. Grafana is a powerful visualization tool that may be used to look at the metrics. There are thirty-nine (39) Tungsten-specific metrics, and these may be viewed using:Įxample metric: # HELP tungsten_connector_version The Tungsten Clustering software version Using tmonitor test, you may view all available metrics. Tungsten Replicator exporter running ok on port 8091Īll 5 exporters are running ok (Up: Tungsten Connector, Tungsten Manager, MySQL, Node, Tungsten Manager exporter running ok on port 8092 Tungsten Connector exporter running ok on port 8093 You may view the full help text for tmonitor with tmonitor help, but here are a few examples: You may even use tmonitor with the external exporters for example, to start, stop, and restart, as well as to install and remove start-at-boot support for the external exporters. The tmonitor command is a simple tool for the management and testing of Prometheus exporters that is bundled with Tungsten products. If you do not want to use command-line tools, you may use a GUI to access the Prometheus metrics. For your convenience, these two binaries are bundled by Tungsten.īy default, Prometheus metrics are exported on port 9100 via path /metrics.Ĭommand-line tools are an easy way to access the metrics: The Tungsten component metric exporters are considered “Internal Scope” and the MySQL Server and Node metric exporters are “External Scope ” this means that the MySQL Server and physical Node metric exporters require an external binary to function (mysqld_exporter and node_exporter). ![]() Knowing how these monitoring metrics work is important when setting up your own unique monitoring solution. Metrics are available for five (5) different components, providing visibility into every layer of the cluster stack: Part of the reason v7+ makes monitoring simpler is that Prometheus metrics are exported by default. Starting with Tungsten v7+ and the new Tungsten APIv2, it’s become easy to leverage the best of these powerful monitoring tools. Prometheus can be used to collect metrics from MySQL clusters, and Grafana can be used to visualize the metrics. Prometheus and Grafana are open source tools that can be used for monitoring MySQL clusters. ![]()
