Galera Clusters
The Galera Clusters dashboard displays all monitored Galera clusters in your environment. The table on the left lists the Galera clusters and current state and health - the percentage of monitored Galera nodes connected to the cluster. When a cluster is selected, the right panel shows a cluster summary, including a health spinner with a time plot popup, the number of running/monitored nodes, cluster membership changes for the selected time window, and a list of nodes. The nodes table displays each monitored node in the cluster with current states, queue sizes, writeset counts, latency, and conflicts. Clicking on the node name drills down to the Galera Node page
Galera Node
The Galera Node page shows Galera-related information for a MySQL server configured as a Galera node. This page shows the current status of the Galera nodes as well as relevant server variables and informational and performance metrics for writesets, flow control, latency, transactions, and replicated data size. At the top right is a summary for the Galera cluster which the node is a part of, showing the number of collected / monitored nodes for the cluster and listing each node in the cluster and their current states. By clicking the name of a different node, the page will update to feature information on the selected node.
