Netweaver

To log, you need a checkpoint group, which can be created on your own or a standard one. Here I reuse the standard group:DEMO_CHECKPOINT_GROUP.

Tcode SAAB, click Display Activate to enter edit mode, set Logpoints to "Log" and date to Today, which means effective on the same day.

It is convenient that most of Netweaver's logging is based on the user level. Create a configuration to turn on the log switch for users who want to turn on logging:

Create a new report named ZCONTEXT. The following code means to write the current report name (contained in the environment variable sy-cprog) and the running environment of the current report (online run or offline run) to the checkpoint group. Because other people may also use the group, use SUBKEY to distinguish between different users.

LOG-POINT ID demo_checkpoint_groupSUBKEY sy-unameFIELDS sy-batch sy-cprog.

CloudFoundry

The total guideline is available on SAP's official Github.

Here is a brief description of the main points.

Slf4j (Simple Log Facade for Java) is recommended for logging in the CloudFoundry environment of SAP cloud platform. That is, the Java code uses the interface provided by slf4j for logging, and the specific logging implementation can be specified through the configuration file.

I made an example, and all the source code is on my github.

My example uses log4j2 as the implementation of logging.

(1) define the version numbers of slf4j and log4j2 in the pom.xml of the Java project.

1.8 1.8 2.1.5 2.8.2 1.7.24

Maintain the relevant dependency in the dependency area of the pom.xml file:

Org.slf4j slf4j-api ${slf4j.version} com.sap.hcp.cf.logging cf-java-logging-support-log4j2 ${cf-logging-version} org.apache.logging.log4j log4j-slf4j-impl ${log4j2.version} org.apache.logging.log4j log4j-core ${log4j2.version} com.sap.hcp.cf.logging cf-java-logging-support-servlet ${cf-logging-version}

(2) create a new log4j2.xml under CLASSPATH and use the following source code:

(3) create a new log instance in SAP cloud platform Cockpit:

(4) use in the code:

Import org.slf4j.Logger; import org.slf4j.LoggerFactory; private static final Logger LOGGER = LoggerFactory.getLogger (ConnectivityServlet.class)

Then use LOGGER.info to log.
