Note: Replication lag alarms are sent from version 1.7.6 and onwards. In earlier versions, replication lag alarms were not always properly raised. If you notice replication lag alarms, you may increase the 'MAX REPLICATION LAG' configuration variable or tune replication and queries.

Note:  Cluster 2 cluster replication using PXC requires that server_id and binlog settings are identical on all nodes of the slave cluster. Read more here.

You can verify that SNMP has been enabled by:


1) Check the /var/log/cmon.log file for the following package installation outputs
 
2021-12-23T04:55:56.617Z : (INFO) Installing SNMP requirement: snmp
2021-12-23T04:56:29.649Z : (INFO) Installing SNMP requirement: snmp-mibs-downloader


2) Verify that the ClusterControl (CMON) mib file has been generated / created
 
ls -l /usr/share/snmp/mibs/SEVERALNINES-CLUSTERCONTROL-MIB.txt
-rw-r--r-- 1 root root 47012 Dec 23 04:57 /usr/share/snmp/mibs/SEVERALNINES-CLUSTERCONTROL-MIB.txt

This file can also be copied to the SNMP manager to be used there if needed

• MySQL 8.0: Fixed an issue with parsing privileges in a GRANT statement (INNODB_REDO_LOG_ENABLE privilege was missing)
• Replication: Fixed an issue retrieving/creating user account information in case there was one server in the setup and it was not configured as a master. The error manifested itself as 'Server not found while trying to create an account'

• Replication:Enable/Disable read-only job: Failed to run if auto_manage_readonly=false
• ProxySQL: Failed to sync instance in ProxySQL (GRANT option).

• Deploy a database stack containing your favorite SQL database and HAProxy load balancer.

• Snapshot MySQL process list before cluster failure. 

• CMON Upgrade operations are logged in a log file.
• Many improvements and fixes for PostgreSQL Backup, Restore, and Verify Backup. 
• A number of legacy ExtJS pages have been migrated to AngularJS.

In this release we are introducing cluster-wide maintenance mode, taking snapshots of the MySQL database status and processlist before a cluster failure, and support for new versions of PostgreSQL, MongoDB, Centos and Debian.

We have previously supported maintenance mode for one node at a time, however more often than not you want to put all cluster nodes into maintenance.
Cluster-wide maintenance mode enables you to set a maintenance period for all the database nodes / cluster at once.

To assist in finding the root cause of failed database nodes we are now taking snapshots of the MySQL status and processlist which will show you the state of the database node around the time where it failed. Cluster incidents can then be inspected in an operational report or from the s9s command line tool.
Finally we have worked on adding support for Centos/RedHat 8, Debian 10, and deploying/importing MongoDB v4.2 and Percona MongoDB v4.0.

• Enable/disable cluster-wide maintenace mode with cron based schedule.
• Enable/disable recurring jobs such as cluster or node recovery with automatic maintenance mode.

• Snapshot MySQL status before cluster failure.
• Snapshot MySQL process list before cluster failure (coming soon).
• Inspect cluster incidents in operational reports or from the s9s command line tool.

• Synchronize time range selection between the Overview and Node pages.
• Improvements to the nodes status updates to be more accurate and with less delay.
• Enable/disable Cluster and Node recovery are now regular CMON jobs.
• Topology view with cluster to cluster replication.

In this release we now support cluster to cluster replication for MySQL Galera and PostgreSQL clusters.
One primary use case is for disaster recovery by having a hot standby site/cluster which can take over when the main site/cluster has failed.
We also added support for MariaDB 10.4/Galera 4.x, ProxySQL 2.0 and managing database users for PostgreSQL clusters.

• Asynchronous MySQL replication between MySQL Galera clusters.
• Streaming replication between PostgreSQL clusters.
• Clusters can be rebuilt with a backup or by streaming from a master cluster.

• MariaDB 10.4/Galera 4.x support.
• ProxySQL 2.0 support.
• Database User Management for PostgreSQL clusters.

=========================================================================

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. 

• Deploy a TimescaleDB server with PostgreSQL (v9.6, v10.x and v11.x).
• Turn an existing PostgresQL server (v9.6, v10.x and v11.x) into a TimescaleDB server.

• Database growth graphs. Track the dataset growth on your databases.
• Support for pgBackRest as a backup tool:
• Create full, differential and incremental backups.
• Restore full, differential, incremental backups.
• PITR - Point In Time Recovery is supported.
• Enable compression and specify compression level.

• Cluster deployment and import of 'replication' type clusters available with:
• Percona Server for MySQL 8.0
• Oracle MySQL 8.0 Server
• Support for 'caching_sha2_password'.

• Use our new spotlight search to quickly open pages, find nodes/hosts and perform cluster and node actions.
• Click on the search icon or use the keyboard shortcut CTRL+SPACE to bring up the spotlight.

• 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.

• Support the use of private IPs when you deploy a cluster to AWS.
  • MaxScale - improved support for v 2.2 and later using maxctrl.
• Automatic vendor/version detection for importing MariaDb/MySQL based clusters.
