Why Monitor?  Optimize database and application performance

–  Performance tuning –  Problem prevention and faster problem resolution

 Lower support costs –  Effective remote/on-premise monitoring and troubleshooting –  Catch problems before they impact the customer –  Identify trends across your customer base

  Increase revenue –  Improve margins by reducing internal development costs of custom monitoring/reporting

tools –  Provide higher SLAs to customer


A Virtual MySQL DBA Assistant!

  Web-based, global view of MySQL/Cluster applications (on-premise and Cloud deployments)

  Automated, rules-based monitoring and alerts (SMTP, SNMP enabled)

  Query capture, monitoring, analysis and tuning, correlated with Monitor graphs

  Real-time Replication Monitor with auto-discovery of master-slave topologies

  Integrated with Oracle Support

Enterprise Monitor - View 1 group

Concentrate on one group of servers (did you notice the group has been renamed?)


Saves time writing, deploying, versioning, maintaining custom scripts. Visualize problems and tuning opportunities you cannot find yourself.

Event Notification

 When a threshold is reached or other issue is identified you are notified, or

  If the severity level changes from a lower status to a higher one

–  The notification is displayed within the MySQL Enterprise Dashboard

–  Events can also trigger additional notifications, such as an email or an SMS text message, or SNMP traps

Severity Level


Dashboard Notifications


 Centralized monitoring of queries without Slow Query Log, SHOW PROCESSLIST;

 Aggregated view of query execution counts, time, and rows

 Visual “grab and go” correlation with Monitor graphs

 Enabled via Connectors (PHP, JDBC, .Net) or MySQL Proxy Saves you time parsing atomic executions from logs. Finds problems you cannot find yourself.

MySQL Query Analyzer


Example query exec with variable substitution

Trace query exec back to source code

Full exec EXPLAIN

Query Execution Drill Downs


  Auto-detects, groups/maintains Master/Slave topologies

  Consolidated, real time status/synch check

  Notifications on Synch Issues   Proactive vs reactive

Saves you time monitoring and collecting replication status/synch data from MySQL command line.

Automated Replication Monitor


Integrated with My Oracle Support

• Collect MySQL diagnostics and upload to MOS SR • Track SRs from Enterprise Dashboard • Create/maintain SRs (CY 2011) • Saves DBA time • collecting data for Support team, tracking status

Which versions of MySQL can I monitor?

 MySQL Enterprise Monitor can monitor any MySQL server running MySQL 4.1 or higher

 The advisors and rules provide specific support for different versions


Authentication

 MEM authentication system  LDAP  PAM


Service Manager Requirements

Recommended: Put the Service Manager on its own server

Minimum Recommended Large (200+ servers)* 2 or more cores 4 or more cores 4 or more cores 2 or more GB RAM 8 or more GB RAM 16 or more GB RAM Disk/I/O subsystem for write-intensive database

RAID10, RAID 0+1 Fast RAID (0+1, 10) array with a number of spindles and fast disks (possibly SSDs) is ideal.

Manager and Agent Roles

 Manager can perform all operations  Agent can be used for individual logins for each agent


DBA Role
