500-425 Exam Dumps : Cisco AppDynamics Associate Administrator (CAAA)

Before creating a new database collector, you need to perform the following actions:

• Verify the database connection details. You need to provide the host, port, database name, and credentials for the database that you want to monitor. You also need to select the database type and the collector type1
• Create a database user and set user permissions. You need to create a database user with the minimum required permissions to access the database and run the queries that the Database Agent needs. You can use the scripts provided by AppDynamics to create the user and grant the permissions2

A group can contain multiple roles, which means that the users in the group inherit the permissions of all the roles assigned to the group. For example, you can create a group that has both the Administrator and the Analytics Administrator roles, and the users in that group can perform both the administration and the analytics tasks1 References: 1: Roles and Permissions

Snapshots are the detailed records of the execution of a business transaction, including the call stack, the exit points, the errors, and the metrics. To locate snapshots showing slow database response, you can use the following methods:

• Go to the list of snapshots and apply a filter based on slow database response: You can access the list of snapshots from the Business Transaction Dashboard or the Tier Dashboard. You can then apply a filter to show only the snapshots that have a slow database response time, which is the time spent by the business transaction in calling the database. You can specify the minimum and maximum values for the slow database response time, or use the predefined options such as slower than 1 second, slower than 5 seconds, etc. You can also combine this filter with other filters, such as time range, business transaction name, tier name, node name, etc. to narrow down the results1.
• From the flow map, right-click the database icon and select view snapshots: You can access the flow map from the Application Dashboard, the Business Transaction Dashboard, or the Tier Dashboard. The flow map shows the graphical representation of the flow of the business transactions, including the tiers, the nodes, the backends, and the remote services. You can right-click on any database icon on the flow map and select view snapshots to see the list of snapshots that have called that database. You can then sort or filter the snapshots by the database response time column to find the slowest ones2.

The other options are not valid methods to locate snapshots showing slow database response. Going to the dashboard for the database and selecting slowest database calls will show the metrics and the flow map for the database, but not the snapshots. Going to the list of snapshots and selecting analyze for a group of snapshots will show the summary and the comparison of the selected snapshots, but not the database response time.
