To help with server management, the Service Manager lets you group servers in any fashion you choose. For example, you can manage servers according to purpose. For example, you might group servers by whether the servers handle Internet or intranet data, by whether they power finance or HR applications, or by physical location.
All monitored servers are automatically included in the top
level server grouping, All Servers
. Other
server groupings are replication groups or user-defined groups.
You can create a user-defined group by clicking the
Manage Servers
link. Add a group name and
then click the button. The
new group is displayed immediately.
Replication groups are automatically discovered by MySQL Enterprise Monitor and in this respect differ from user-defined groups. For more information about replication groups see Section 15.14, “The Replication Tab”. However, like user-defined groups you can edit the name of a replication group and add other servers to it.
To add to a group, select the add to group
link. Choose the server or servers you wish to add and then
complete the operation by choosing the button. You can add a server to a group even
if the agent is down.
To remove a server from a group expand the server group tree and
click the remove from group
link. To delete a
server altogether see
Section 15.8.3.3, “Removing a Server From the Dashboard”.
Slaves removed from a replication group are rediscovered and re-added to that group.
To delete an group, you can use the Delete Group link. This deletes the group and removes the servers from the deleted group.
You cannot delete automatically created groups, such as those built during replication discovery, unless the group is empty. If the group is not empty, you get a error.
There are three ways to modify an existing group; by renaming
it, adding to it, or removing it. Select the
rename
link to change the name of a group and
add to group
to add servers. Deleting a group
simply requires clicking the remove all from
group
link. This removes the server group but has no
effect on individual servers.
