Managing database groups

In large monitored environments that include a high number of database instances it might be useful to create separate groups of database instances that share some common attributes, and to monitor the individual groups separately. Using the Databases view on the navigation panel, it is possible to group database instances either by identifying specific database instances, or services that contain specific database objects, and adding them to the group. This view allows you to create, edit, and remove database groups, thereby serving as a filter for the list of database instances.

When grouping database instances by services, you first need to associate the database instances with services and then identify the services that contain one or more objects used by the monitored databases. For more information about services in Foglight, see the Foglight User Help.

To filter the list of databases by selecting services:
* 
IMPORTANT: Ensure that you already have Sybase services defined in Foglight, and that they include Sybase components.
1
To create a Sybase service, using the Service Builder, create a new category with a DB tier and add the applicable Sybase objects to it. For more information about Foglight services, see the Foglight User Help.
2
On the navigation panel, under Databases, click the box on the right of Group by and choose Services.
The Databases view refreshes, showing groups of monitored resources created using the Service Builder dashboard, and containing the Foglight for Sybase database topology. The SLC column, also appearing in this view, indicates the current availability of each service over a given period of time.
3
Select the services that are associated with the database instances that you want to see listed.
The display area refreshes, showing the database instances whose objects are monitored with the selected services.

To create a database sub-group:
1
On the navigation panel, under Databases, select Database Groups and click .
The Add Sub Group dialog box appears.
2
In the Name box, type the name of the sub-group. Optionally, provide the sub-group’s description in the Description box.
3
Select one or more database instances in the Available list and click to move them to the Selected list.
Alternatively, click to select all of the databases instances.
* 
TIP: To remove database instances from Selected, use and , as required.
4
Click Ok.
The sub-group name appears in the list and the database instances you selected in Step 3 appear in the list of databases.
To manage database groups:
•
To remove a database group, select it on the navigation panel and click . When prompted, click Remove.
•
To edit the list of database instances associated with a database group, select it on the navigation panel and click . Make your changes, as required.

Exploring the state of selected database instances

Clicking a database instance in the databases table opens a cue card, which gives you more details about the selected database.

About the Sybase_MDA Agent

The Sybase_MDA Agent monitors the performance of the Sybase Adaptive Server Enterprise 12.5.1 and above. A unique characteristic is the ability for a user to select a “monitoring level” (called Availability Performance and Diagnostic). Each level is associated with a group of tables and their associated collection. By default, Availability and Performance tables are activated and all others are turned off. You can optionally select or clear Configuration, Performance or Space Trending to tune the agent to collect the metrics important to your environment.

In addition, all tables that can return multiple rows have a corresponding entry in the agent properties to limit the incoming data (see the Data Retrieval properties). The Limit Incoming Rows property displays a set of criteria developed to limit the amount of data written to the Foglight database. These values are used strictly to manage the amount of data written to the Foglight database and NOT to configure the Rules. Rules are still configured by registry variables.
