Tungsten Clustering contains many tools to monitor your cluster, and today we will look at a new one - the `tungsten_get_status` command, included with Tungsten versions 6.1.19+ and 7.0.2+. This tool was created in response to a customer request for a simple script that could display the status of all nodes cluster-wide for any topology from a single place. The status includes the datasource and replicator layers along with the policy for each cluster.

We are pleased to announce that Tungsten Clustering and Tungsten Replicator GA version 6.1.18 are now available. Tungsten allows enterprises running business-critical MySQL database applications to cost-effectively achieve continuous global operations with commercial-grade high availability (HA), geographically redundant disaster recovery (DR) and geographically distributed active/active.

Prometheus and Grafana are open source tools that can be used for monitoring MySQL clusters. Prometheus can be used to collect metrics from MySQL clusters, and Grafana can be used to visualize the metrics. Starting with Tungsten v7+ and the new Tungsten APIv2, it’s become easy to leverage the best these powerful monitoring tools have to offer.

This blog is an announcement about a new Webinar. The speaker, Matthew Lang, is the Director of Customer Success for the Americas at Continuent. He covers the significance of this exciting major release in context of previous major releases, and some of the highlights and main benefits.

Tungsten Clustering is a powerful tool with many moving parts, including the Tungsten Connectors which may be installed on any application server. During a troubleshooting event, it is helpful to understand what to look for and where, in addition to understanding how the logs work together to provide a clear picture of the situation. In Tungsten version 7, we introduced a number of features designed to make troubleshooting easier, and this blog will cover some of that too.

This blog post will walk you through configuring HA Proxy for the Tungsten Dashboard, along with the new command `tpm generate-haproxy-for-api` which helps automate the process by translating existing INI files into haproxy.cfg config file format. The Tungsten Dashboard is a browser-based GUI, designed to make using a Tungsten Cluster as easy as possible.

We are pleased to announce that Tungsten Clustering and Tungsten Replicator GA versions 7.0.1 are now available. This new minor release includes 52 new features and improvements, including two critical bug fixes. Read this blog to learn about the new v7.0.1 release!

Sometimes you really, really want to know what a MySQL client is asking of the MySQL server. As of Tungsten Clustering v7.0.0, you may now enable Connector Audit Logging, which captures data transferred between client applications and MySQL servers to a file, database or socket. This blog post will walk you through the feature and how to enable, configure and disable Tungsten Connector Audit Logging.

In this post we will explore a new command in v7.0.1, tpm report. The purpose of tpm report is to provide easy access to all of the settings that pertain to a specific topic. Since Security is a high priority at Continuent, the current default (and only) topic is the Security stance. The tpm report command will evolve and grow over time. This first version is Continuent’s way of providing as much transparency about Tungsten Cluster Security as possible.

In our last blog post on this topic we covered the basics of the new REST  API available with Tungsten version 7.0.0. In this post, Part 2, we explore the REST API in more detail, including payloads and advanced functionality. The API provides a vast pool of capabilities, and here we barely scratch the surface of what can be accomplished.
