    • Agent Based Monitoring (Prometheus):
      • Uptime were set to 0.
      • Disk stats for the controller is now also available.
      • node_disk_written_bytes_total | node_disk_read_bytes_total are now also collected.

  • .Controller:
    • Monitoring/SCUMM: PostgreSQL exporter and MySQL exporter URL password encoding fix which could cause a No data points in Dashboards →Postgres Overview.
    • Monitoring/SCUMM: A fix for disk stats to be properly shown when using LVM volumes in the Nodes →Disk charts.

Maintenance Release: May 7th, 2019

  • Build:
    • clustercontrol-controller-1.7.2-3167

  • Controller:
    • MySQL 8.0: Fixed an issue preventing db users from being created on MySQL 8.0.

    • SCUMM: Preserve the exporters of other clusters in Prometheus configuration during (re)deployment. (Note: Users with multiple clusters and wrong Prometheus configuration may need to re-deploy the Prometheus on the affected [No data point] clusters).
    • Query Monitor: Fixed an issue where queries were dropped following a schema update when upgrading clustercontrol-controller.

We are proud to announce an expansion of the databases we support to include TimescaleDB, a revolutionary new time-series that leverages the stability, maturity and power of PostgreSQL. TimescaleDB can ingest large amounts of data and then measure how it changes over time. This ability is crucial to analyzing any data-intensive, time-series data. For ClusterControl, this marks the first time for supporting time-series data; strengthening our mission to provide complete life cycle support for the best open source databases and expanding our ability to support applications like IoT, Fintech and smart technology.

In this release you can now deploy a TimescaleDB and also turn an existing PostgreSQL server to a TimescaleDB server. PostgreSQL clusters also support a new backup method pgBackRest, database growth charts and improvements to manage your configuration files.

MySQL users can start to deploy and import MySQL 8.0 servers with Percona and Oracle MySQL and our new Spotlight search helps you navigate through pages, find nodes, and perform actions faster.

Finally, we are also providing a beta version to setup CMON / Controller High Availability using several ClusterControl instances wired with a consensus protocol (raft) between them.

Feature Details

  • TimescaleDB – optimized for time-series data using SQL – more documentation coming soon!
    • Deploy a TimescaleDB server with PostgreSQL (v9.6, v10.x and v11.x).

  • PostgreSQL
    • Database growth graphs. Track the dataset growth on your databases.
    • Support for pgBackRest as a backup tool:
      • Create full, differential, and incremental backups.

    • CMON HA is using a consensus protocol (raft) to provide a high availability setup with more than one cmon process.
    • Setup a ‘leader’ CMON process and a set of ‘followers’ which share storage and state using a MySQL Galera cluster.
  • Misc
    • Support the use of private IPs when you deploy a cluster to AWS.
