Initial Release: Feb 25th, 2016

  • Build number:3
    • clustercontrol-1.2.12-1007
    • clustercontrol-cmonapi-1.2.12-156

  • Operational Reports (BETA). Generate, schedule and email out operational reports. The current default report shows a cluster’s health and performance at the time it was generated compared 1 day ago.
    • The report provides information on Node availability, Backup summary, Top queries, Host and Node stats. We will add more options and report types in future releases.
  • Custom Advisor dialog. Create threshold based advisors with host or MySQL stats without needing to write your own JS script.
  • Notification Services (new clustercontrol-nodejs package). Currently only email and pagerduty notifications are used by custom advisors. More to come.
  • Local Mirrored Repository. Create a local mirror of a database vendor’s software repository. This allows you to freeze the current versions of the software packages used to provision a database cluster for a specific vendor and you can later use that mirrored repository to provision the same set of versions when adding more nodes or deploying other clusters.
  • Export graphs as CSV, XLS files.
  • Search the content in the system logs.
  • MySQL based clusters
    • Galera
      • MariaDB 10.1 support.
      • Enable binary logging for a node. This node can then be used as the master for a replication slave or use the binary log for point in time recovery.
      • Delayed replication option when adding slave to the Galera Cluster. Delay the replication with N seconds.
      • Enable/Disable SSL encryption of Galera replication links.
    • MySQL Replication Master
      • Oracle MySQL 5.7 as vendor. Limitation: Percona Xtrabackup is not supported for MySQL 5.7 yet.
      • Semi-sync replication option.
      • Find the most advanced MySQL slave server to use for Master promotion.
    • MySQL Replication Slave
      • Delayed replication option (MySQL 5.6). Delay the replication with N seconds.
      • New table lists delayed replication slaves in the cluster.
    • New Backup options
      • Auto Select backup host. Allow ClusterControl to automatically select which node to take the backup on.
      • Enable backup failover node. If the selected backup node is down a failover node will be elected.
      • Galera: De-syncing a node with the highest local index and then used as the backup failover node.
      • MySQL Replication: Random slave node used as the backup failover node.
      • “No backup locks” for xtrabackup/innobackupex. Use FLUSH NO_WRITE_TO_BINLOG TABLES and FLUSH TABLES WITH READ LOCK instead of LOCK TABLES FOR BACKUP.
    • Configuration Management
  • MongoDB
    • Support for MongoDB 3.2
  • Postgres
    • Support for Postgres 9.5
