Java Backend Detection

Related pages:

The AppDynamics Java Agent automatically discovers common types of remote services as backend systems based on the exit point associated with the backend. If AppDynamics does not automatically discover a backend system used in your environment, check whether it's an automatically discovered type (based on the list below) and compare the default exit points for the type to that used in your application environment.

Each automatically discovered backend type has a default discovery rule. Many backend types have a set of backend naming properties. Where individual properties are configurable, you can configure the property as follows:

Use the property as is.
Use segments of the property.
Run a regular expression on the property. See Using Regular Expressions.
Execute methods on the property. See Using Getter Chains.

For instructions to revise backend discovery rules, see Backend Detection Rules.

Apache Cassandra CQL Backends

By default, AppDynamics automatically detects and identifies exit calls to Apache Cassandra using Thrift and DataStax drivers.

Exceptions returned from Cassandra backends show up as separate exit calls. For the DataStax 1.0 driver, the Java Agent detects an "unknown" Cassandra backend in order to capture the error details.

Cassandra Backend Naming Properties

You can enable or disable the use of the properties below for Cassandra backend identification:

When you configure Cassandra backend naming, consider the following:

For DataStax clients, AppDynamics does not recommend using the keyspace property. Due to driver limitations, the keyspace property is only available when Statement.setKeyspace is called explicitly in Cassandra. This can lead to the discovery of multiple backends.
Thrift clients don't support Cluster Name, Rack or Data Center properties, so those properties return null for Thrift.

Configurable Properties	Default Automatic Cassandra CQL Backend Discovery/Naming
Cluster Name	Yes
Keyspace	No
Host	Yes
Port	Yes
Data Center	No
Rack	No

Apache Kafka Backends

By default, the Java Agent detects publish activity to Apache Kafka as an exit point from a Java node. You can configure the Java Agent to detect Kafka consumer activity as an entry point, see Apache Kafka Consumer Backends.

For sample JDBC backend configurations, see Example JDBC Backend Configuration.

IBM Websphere Message Queue Backends

IBM MQ, also known as IBM WebSphere MQ and IBM MQSeries, is IBM's message-oriented middleware similar to JMS. Several additional properties are configurable, such as host and port. This is useful where you have lots of queues and you want to monitor them based on a subset of the properties.

Java Message Service Backends

JMS backend activity includes all JMS message send and publish activity. By default, AppDynamics identifies JMS back ends using the properties of the JMS server such as: vendor, destination name, and destination type. The default configuration uses all three properties of the JMS queue.

JMS Backend Naming Properties

You can enable or disable the use of the following properties for JMS backend identification:

Configurable Properties	Default Automatic JMS Backend Discovery/Naming

JDBC Backends

JDBC backend activity consists of all JDBC calls including inserts, queries, updates, getting connections from connection pools, and so on.

Class	Method
`oracle.jdbc.driver.PhysicalConnection`	`prepareStatement` `prepareCall` `commit` `rollback`
`oracle.jdbc.driver.OracleStatement`	`executeQuery` `executeUpdate` `execute`
`oracle.jdbc.driver.OracleDataSource`	`getConnection`
`oracle.jdbc.driver.OraclePreparedStatement`	`executeQuery` `addBatch` `execute` `executeUpdate`
`oracle.jdbc.driver.OraclePreparedStatementWrapper`	`execute` `executeQuery` `executeUpdate`

The Java Agent measures the response time for a database call as the round trip time it takes for a JDBC call to return. The response time for a database call includes network round trip time + database connection time + SQL query time or any other time spent in the database.

By default, the agent identifies JDBC backends using the following logical properties of the database:

URL
Host name
Port number
Database schema
Version
Vendor

If a database backend has the same hostname, port number, and database type as a database server already configured in a database Collector, the database backend is automatically matched with the Collector, and drill-downs from the Application Flow Map, Tier Flow Map or Node Flow Map to Database Monitoring are enabled.
