The Global Settings control the main configuration parameters for the entire MySQL Enterprise Monitor system, including your email notifications, data purge, and My Oracle Support credentials.
The Global Settings tab is divided into these sections:
Configures the settings for email notifications by MySQL Enterprise Service Manager. Configure the From Address SMTP Server settings. If your server requires authorization, complete the necessary server login details, and whether SSL is required.
Because alert notification via email is a key component of the
MySQL Enterprise Monitor Advisor solution, consider configuring an SMTP
account for at least one recipient. Choose the
Settings tab and go to the
Global Settings screen by clicking the
appropriate link. Here you configure the email settings that
apply to the currently logged-in user.
Outgoing Email Settings on the
left of this page.
Ensure that the
Enable Email Notifications
checkbox is checked and enter information as appropriate.
The default value for the SMTP port is
If your mail server runs on a different port, specify the
port, separated from the server name by a colon. For example,
if your mail server runs on port 587, enter
into the SMTP Server text box.
An email server must be available for sending email alerts.
The SMTP client uses Transport Layer Security (TLS) if the SMTP server supports it.
If your SMTP server incorrectly indicates that it supports TLS, check the Disable JavaMail TLS/SSL check box.
To enter the SMTP server password, check the Update Password On Save box first. When you return to this dialog to update settings other than the SMTP password, leave this box unchecked to avoid blanking out the saved password. If the SMTP password does change later, check the box again and enter the new password.
To test your configuration immediately, add an email address to the On Save, Send Test Email Message to box.
For more information, see Outgoing Email Settings.
The SNMP Traps section of the Global Settings tab lets you enable Simple Network Management Protocol so that your Network Management System (NMS) can handle MySQL Enterprise Monitor events. SNMP notifications are off by default. To enable the checkboxes that associate specific rules with SNMP traps, click the Enable SNMP Notifications checkbox first.
MySQL Enterprise Service Manager includes support for both SNMPv1 and SNMPv2. You can select the SNMP version to use by clicking the corresponding Use SNMPv1 or Use SNMPv2 radio button.
In the Target 1 or Target
2 text box enter the IP address or hostnames of
your NMS listeners. The port number defaults to the well-known
162. If you are not using this
port, enter the port that your Network Management System is
Enter the appropriate community string in the
Community String text box. The default
value for this string is
For the trap address for Advisor traps, you can optionally elect to use the address of the agent that triggered the alert, rather than the address of the MySQL Enterprise Service Manager. To do this, click the Use the remote MySQL agent host IP address as the SNMP trap agent address for Advisor traps. For internally generated SNMP traps (that is, with MySQL Enterprise Service Manager) you can also specify an alternate address by putting the IP address in the SNMP trap agent address for internally generated traps box.
To ensure that the specified target is valid, check the
On Save, Send Test Trap check box. The
remaining check boxes configure how your NMS responds to
MySQL Enterprise Monitor. Check the Up/Down Application
check box to configure NMS for starting up or shutting down
the MySQL Enterprise Monitor. For configuration of advisor events, choose a
level of severity and check the Advisor event with
the severity of
check box. Finally, choose the Application
Error check box to configure NMS to support
application error traps. Be sure to save your settings before
To enable SNMP traps, check
Enable SNMP Notifications checkbox,
then check the
Use SNMP Traps checkbox for
each rule that should result in an SNMP trap. For instructions
on doing this, see Section 2.3.2, “Scheduling Rules”.
The Management Information Base (MIB) file associated with
SNMP trapping is called
the location this file see
Section C.1.4, “The Management Information Base (MIB) File”.
The MIB file supplied with MySQL Enterprise Service Manager is not directly compatible with OpenNMS. For a sample of the modifications to make, see the comments for Bug #41714.
Server Locale setting determines the
language of notification for the following items:
The naming conventions for shared resources such as a replication group name prefix.
The initial value in this drop down list box is the locale for the OS on which the Dashboard is running.
You can alter the hostname and port used to identify the MySQL Enterprise Service Manager when reporting notifications. This can be useful if the server hostname, and the hostname you want to use when connecting to your MySQL Enterprise Service Manager.
Only change the Port setting if you have altered or redirected the original port used when installing MySQL Enterprise Service Manager. Entering the incorrect information does not affect the accessibility of your system, except when clicking links within the notification messages.
The Data Purge Behavior section of the
Global Settings tab lets you remove old
log files and also old data from the repository. The default
purge interval is
28 days. To purge data,
change this setting by choosing from the drop-down list.
52 weeks, for example, removes all
data that is older than a year.
Purging data permanently removes information from the repository. Since events are derived from data contained in the repository, they are purged along with the data.
Ensure that there is adequate disk space for the repository. If you are monitoring numerous servers and running many rules the size of the repository can increase rapidly. Choose purge behavior accordingly.
The purge process is started approximately once every day, or when the MySQL Enterprise Dashboard is restarted. If you change the purge duration from a larger timespan to a smaller one, the data may start to be purged immediately.
The system assumes that you will close events (or they will be auto-closed). The purge functionality only purges closed events and related data. Note that leaving events open for long time spans will use more data storage space.
You can configure the data purge behavior for a number of different systems individually:
Remove Historical Data Collection Older Than configures the duration that the main data about your servers is retained. This includes all data collections, including CPU, memory and connections and activity statistics.
Remove Query Analyzer Data Older Than configures the duration that the query analyzer statistics and information about individual queries is retained.
Notes for setting purge behavior:
Purging can be carried out manually by enabling the
innodb_file_per_table for the
repository database and then using an
TABLE operation to reclaim space from deleted
rows in the table.
If you set the purge value to a very low timespan value
when the previous setting was quite high, then the space
used for the data that was purged is not reclaimed from
the InnoDB tablespaces. You can do this by running
OPTIMIZE TABLE on the MySQL tables for
MySQL Enterprise Service Manager to reclaim the space from the purged rows.
MySQL Enterprise Monitor keeps track of all the databases and tables in a server, as well as the amount of RAM, disk space, and other items. A re-inventory updates this information in case you have added or dropped databases and tables. Depending upon the configuration of your system, this operation can tax resources. If you are monitoring many remote servers this is an operation you may want to perform in off-peak hours only.
My Oracle Support Credentials
You can specify the credentials for logging into the My Oracle Support site. These should match the user name and password that you have registered with Oracle for access to the support site.
Only administrators can change the
Support Credentials section; for other users, this
section does not show up in the interface. For more
information about different users and their rights see
Section 2.8.4, “Managing Users”. Specifying incorrect
credentials results in the error message, “Your
credentials do not appear to be valid.”
HTTP Proxy Settings
You might want to update your HTTP Proxy Settings if your MySQL Enterprise Service Manager is not directly connected to the internet. The proxy settings are used when updating the information within the What's New tab. For more information, see Section 2.9, “The What's New Tab”.
You can update your Advisor Bundle and the associated rules and graphs by importing a new Advisor Bundle. To update your Advisor Bundle using a bundle file that you have previously downloaded:
Click Choose File and locate your Advisor Bundle on your computer.
Click Save to upload the updated bundle and validate the contents.
To update the Advisor Bundle automatically over the web, click the update advisors button.
You can configure LDAP Authentication to be used for the users that are provided access to the MySQL Enterprise Dashboard. To use LDAP authentication, it must have been enabled and configured within the settings.
The configurable elements for LDAP authentication are:
Use LDAP for Authentication
To enable LDAP authentication, click the Use LDAP for Authentication checkbox.
LDAP is Authoritative
If you want to make LDAP the authoritative (only) authentication mechanism, check the LDAP is Authoritative checkbox. Note that if you select this option and the LDAP service is misconfigured, you can lock yourself out of MySQL Enterprise Dashboard entirely.
Primary Server Hostname
Hostname or IP address of the primary LDAP directory server.
Port number of the primary LDAP server. You must change this option to the port used for SSL connections if you have enabled encryption.
Secondary Server Hostname (optional)
Hostname or IP address of the secondary/failover LDAP directory server.
Port number of the secondary/failover LDAP server. You must change this option to the port used for SSL connections if you have enabled encryption.
Encryption type required for communication with the LDAP
server(s). Supported options are
Authentication should follow any referrals provided by the
server. The default is to use whatever the LDAP directory
server is configured to do. If you are using Microsoft
Windows Active Directory, you must set this option to
The authentication mode to use. Choices are
as User, which binds to the LDAP directory using
the credentials given to login to MySQL Enterprise Service Manager.
Comparison requires an LDAP
login/password that can see the configured password
attribute to make a comparison with the given credentials.
Update Password On Save box and password fields
To enter the LDAP server password, check the Update Password On Save box first. When you return to this dialog to update settings other than the LDAP password, leave this box unchecked to avoid blanking out the saved password. If the LDAP password does change later, check the box again and enter the new password.
User Search Pattern
Pattern specifying the LDAP search filter to use after
substitution of the username, where
marks where the username should be substituted for the DN.
User Search Base (leave blank for top level)
The entry to use as the base of the subtree containing users. If not specified, the search base is the top-level context.
Search entire subtree
The search scope. Set to
true to search
the entire subtree rooted at the *User Search Base entry.
The default value of
false requests a
single-level search including only the top level.
Map LDAP Roles to Application Roles
Specifies whether MySQL Enterprise Service Manager should use the roles defined in LDAP to map to MySQL Enterprise Monitor application roles. If enabled, and LDAP is not configured to be authoritative, if a user authenticates successfully via LDAP and has a valid mapped role, they are granted permissions to the application. Roles are mapped according to the entries in the Application Role/LDAP Role(s) fields, which take comma-separated lists of LDAP roles to map to the given MySQL Enterprise Monitor roles.
If you select this option, you are provided with additional fields that let you configure how roles are looked up within the LDAP server.
For more information on LDAP authentication and integration with Tomcat, see Tomcat Documentation.
These settings change the way host names are displayed in the Dashboard, typically by shortening the names to avoid cluttering the display with repetitive information:
The Show MySQL server names as field
controls whether the Dashboard displays fully qualified
domain names (the default); or only the host name,
omitting the repetitive suffix such as
or host names transformed by a substitution expression,
for example to turn a long multi-part host name into a
The syntax for the substitution expression is a name-value
pair separated by an equals sign, with a regular
expression on the left side and the replacement text on
the right side. The regular expression follows the Java
To keep special characters (particularly dot) from being
interpreted within the regular expression, escape them
\ or make a single-item character
[.] for example. If the right
side contains whitespace, a comma, or is an empty string,
surround it with single or double quotation marks. You can
use backreferences such as
$2, and so on to substitute parts of
the regular expression into the replacement text; you
cannot use the
$ character in the
replacement text except as part of a backreference. You
can include more than one replacement expression by
separating them with commas. Some examples include:
dx521\.example\.com=Staging dx984[.]example[.]com=Production database-server-(.*?)\.example\.com=$1 ^database-server-="", [.]example[.]com$="", dx521="Staging DB", dx984="Production DB"
If you use incorrect syntax in the replacement expression,
the original hostname is displayed with a suffix such as
( ! ); this suffix varies depending on
your locale setting.
The Display connection endpoint
values controls whether the detailed connection
part of the hostname (such as the TCP/IP port number) is
displayed. By default, it is always shown. You can set it
to never be shown, or to only be shown if it is not the
standard value. For TCP/IP connections, the default port
is 3306. For socket connections, the default endpoint
