Support for PostgreSQL Servers! - Add Existing PostgreSQL Server (standalone). Only v9.x supported. - Monitor and schedule backups - Query Monitor
Port 9500 must be open on the controller for internal communication between UI and the CMON process
Galera Cluster - Bootstrap Cluster. Select a DB node to initialize the cluster from. Optionally enable/force SST for joining nodes and forcefully stop (SIGKILL) nodes - Stop Cluster forcefully (SIGKILL) or with a graceful shutdown time - Start DB node. Optionally enable SST at startup - Stop DB node forcefully (SIGKILL) or with a graceful shutdown time - Make a non-primary DB node primary - Replication Slave Setup for Galera Cluster (GTID support). Slaves are bootstrapped with a Xtrabackup stream from a chosen Master - Failover replication (GTID only) slave from to a new master - Stage replication slave from master (Xtrabackup streamed from master to slave), useful in event of slave corruption - Enable SSL Replication Encryption on the Galera Cluster. 2048-bit default key and certificate generated on the ClusterControl node and transferred to all the Galera nodes automatically - SSL support between controller and managed nodes - wsrep-recover is used to discover the most advanced Galera Node for recovery operations - Removed manipulation of wsrep_cluster_address in my.cnf files meaning ClusterControl no longer makes any alterations of a node's configuration file - Backup functionality completely re-written, and netcat port for streaming backups is user specified - Restore ClusterControl originated or external made backups on selected hosts - Alarm is raised if a node has set wsrep_cluster_address=gcomm:// - Improved logging and hints to assist with failed recovery attempts - Enable/Disable Node/Cluster Auto Recovery from UI
Advanced HAProxy Deployment Settings - Set for example client and server timeouts, max connections for frontend and backend. Select which backend servers are 'active' or 'backup' - It is possible to enable/disable nodes part of a load balancer. - Built-in HAProxy Statistics. No longer need to launch separate window to monitor the HAProxy performance - Template configuration is stored on the controller in /usr/share/cmon/templates/haproxy,cfg , mysqlchk.*, and mysqlchk_xinetd and allows for pre-install modifications.
Deadlock and long running queries detection - db_long_query_time_alarm (specify in cmon.cnf). If a query takes longer than db_long_query_time_alarm to execute an alarm will be raised containing detailed information about blocked and long running transactions. db_long_query_time_alarm = 0 (disable), default value 5
MySQL Replication / Single MySQL Server - Failover replication (GTID only) slave from to a new master - Stage replication slave from master (Xtrabackup streamed from master to slave), useful in event of slave corruption
MongoDB Cluster - New Overview page with global lock stats.
A new more “modern” front-end theme - Re-organized Cluster specific actions into an easy to access list. - A global alarm list which shows alarms per cluster. No need to drill into each cluster to see the alarms anymore.
New configuration options (cmon.cnf): - enable_mysql_timemachine =[0|1] , default is 0, meaning it is disabled. - cmondb_ssl_key= path to SSL key, for SSL encryption between CMON and the CMON DB. - cmondb_ssl_cert = path to SSL cert, for SSL encryption between CMON and the CMON DB - cmondb_ssl_ca = path to SSL CA, for SSL encryption between CMON and the CMON DB - cluster_ssl_key= path to SSL key, for SSL encryption between CMON and managed MySQL Servers. - cluster_ssl_cert = path to SSL cert, for SSL encryption between CMON and managed MySQL Servers. - cluster_ssl_ca = path to SSL CA, for SSL encryption between CMON and managed MySQL Servers. - cluster_certs_store = path to storage location of SSL related files, defaults to /etc/ssl/<clustertype>/<cluster_id>
Monitoring: - New binary format for host statistics which consumes less space (cpu, memory, disk, network stats) - Fixed disk statistics collector to support non 4K block sizes
Security: - E-mails do not contain IP addresses when hostnames are specified in the cmon configuration - Password will not be logged (to jobs for example) or sent anymore
Alarms: - Alarm will be raised when there is a missing MySQL GRANT - Alarm will be raised/sent when there is a high IO wait for a period (>=50% average in 10 minutes) - New alarm for Galera configuration problems - Improved alarm emails (for example: high cpu/mem usage mails will contain the output of 'top' command)
RPC: - Several new RPC interfaces (directly on the daemon) for jobs and statistics handling - The web client has started to migrate over to use RPC API calls instead of the CMON API
Testing: - Acceptance testsuite which runs daily using vm instances
Other: - Job failures are much better explained - Huge refactor for cluster handling, it is now mostly unified - Improved host/node handling (makes it possible later on to add support for multiple services on a single host) - Better CentOS7 / systemd support - cmon init script updates (and unified across distros [redhat/debian]) - Support for more detailed SSH logging if needed - Agents are no longer supported
