This page lists hardware and software requirements using Database Visibility.
Agent Hardware Requirements
Hardware requirements vary depending on database activity. If your database activity increases, you may need to adjust your hardware configuration.
The machine running the Database Agent should meet following hardware requirements:
- 1 GB of heap space and an additional 512 MB of heap space for each monitored database instance. For less busy databases, you may reduce the heap space to 256 MB per monitored database instance.
- 2 GHz or higher CPU
Examples of heap space allocation:
- Monitoring 5 databases instances requires ( 5 x 512 MB ) + 1024 MB = 3,584 MB
- Monitoring 20 database instances requires ( 20 x 512 MB ) + 1024 MB = 11,264MB
- Monitoring 100 database instances requires ( 100 x 512 MB ) + 1024 MB = 52,224 MB
AppDynamics Controller Sizing Requirements
The controller database should meet the following hardware requirements:
- 500 MB of disk space per collector per day
- 500 MB of disk space for the Events Service per day. By default, the Events Service retains data for 10 days.
For information on additional hardware requirements for the AppDynamics Controller to support Database Visibility, see Controller System Requirements.
Start the Controller Events Service
- The Database Agent runs on a Java Virtual Machine. You must have Java 1.8 or later.
- The operating systems Linux and Windows are supported
- The machine on which the database is running or the machine you want to monitor must be accessible from the machine where the Database Agent is installed and running. This machine must have a network connection, internet or intranet.
- If your databases are behind a firewall, you must configure the firewall to permit the machine running the Database Agent program access to the databases. The database listener port (and optionally the SSH or WMI port) must be open.
- The network bandwidth used between the agent and the controller is approximately 300kb/min per collector for a large database with 200 clients using 50 schemas, processing about 10,000 queries a minute. The actual numbers depend on the type of database server, the number of individual schemas on the server, and the number of unique queries executed daily, and will therefore vary.
