Advisor Categories

The following types of Advisor are provided:

  • Administration: Checks the MySQL instance installation and configuration.

  • Agent: Checks the status of each MySQL Enterprise Monitor Agent.

  • Availability: Checks the availability of the MySQL process and the connection load.

  • Backup: Checks whether backup jobs succeed or fail, required resources, and information about MySQL Enterprise Backup specific tasks.

  • Cluster: Checks the status of the monitored MySQL Cluster.

  • Graphing: Data for graphs.

  • Memory Usage: Indicate how efficiently you are using various memory caches, such as the InnoDB buffer pool, MyISAM key cache, query cache, table cache, and thread cache.

  • Monitoring and Support Services: Advisors related to the MySQL Enterprise Monitoring services itself.

  • Operating System: Checks the Host Operating System performance.

  • Performance: Identifies potential performance bottlenecks, and suggests optimizations.

  • Query Analysis: Advisors related to Queries and Query Analysis.

  • Replication: Identifies replication bottlenecks, and suggests replication design improvements.

  • Schema: Identifies schema changes.

  • Security: Checks MySQL Servers for known security issues.

It is also possible to create custom Advisors.

To display the Advisors in each category, click on the Category name. For a full description of the default advisors, see Chapter 21, GUI-Based Advisor Reference and Chapter 20, Expression-Based Advisor Reference.

Advisors configure the type of data collected by the Agent. If you do not want to monitor for a specific type of data, disabling the Advisor responsible for that data type instructs the Agents to stop collecting that data.

Advisor Listing Table

The listing table displays all categories, Advisors, monitored instances, and displays information on the configuration of the Advisors.

The configuration information is displayed in the following columns:

Note

Group and Host Menu

Each advisor contains the list of all groups defined in MySQL Enterprise Monitor. To see these groups, expand the contents of the Advisor by clicking on the Advisor’s name. This enables you to specify the Advisors you want to run for each group.

The top-level advisor contains the global configuration for all groups. That is, the configuration at the advisor-level applies to all groups and hosts it contains. Each nested group, and the monitored hosts contained in the group, have a drop-down menu enabling you to override the global configuration for each group or host, or disable the advisor for the specific group or host. Any change in advisor configuration at the group or host level, overrides the global configuration specified at the advisor level.

To open the Group menu, expand the Advisor and select the drop-down icon next to the Group name. The same menu is used for each host within the group. The menu contains the following items:

  • Override Advisor Configuration: opens the Advisor edit dialog, enabling you to change the Advisor's configuration for the assets in the group. Changes made at the group level, only affect the assets within the group.

    Important

    If a host, Host1 for example, exists in multiple groups and a configuration override is applied to one of those groups, it does not affect Host1. Data is still collected and events generated for Host1 because it exists in different groups within the same advisor. To ensure the override applies to Host1, you must apply the same override to Host1 in each group which contains it.

  • Disable Advisor: disables the Advisor for the selected group or host.

Advisor Filter

The Advisor filter enables you to search for specific Advisors, groups, hosts, or assets using text or regular expressions. To open the filter, click the filter button. For information on the named filters, see Section 15.3.5, “System and User-defined Filters”.
