Enabling debug logging

Edge for Private Cloud v. 4.17.09

You can enable debug logging for several Edge components. When you enable debug logging, the component writes debug messages to its system.log file.

For example, if you enable debug logging for the Edge Router, the Router writes debug messages to:

/opt/apigee/var/log/edge-router/logs/system.log

Note: Enabling debug logging can cause the system.log file for a component to grow very large in size, and can affect the overall system performance. It is recommended that you enable debug logging for only as long as necessary, and then disable it.

Use the following API call to enable debug logging for a component:

curl -X POST "http://localhost:PORT/v1/logsessions?session=debug"

To disable debug logging:

curl -X DELETE "http://localhost:PORT/v1/logsessions/debug"

Each Edge component that supports debug logging uses a different port number in the API call, as shown in the following table:

Component	Port	Log file
Management Server	8080	/opt/apigee/var/log/edge-management-server/logs/system.log
Router	8081	/opt/apigee/var/log/edge-router/logs/system.log
Message Processor	8082	/opt/apigee/var/log/edge-message-processor/logs/system.log
Qpid Server	8083	/opt/apigee/var/log/edge-qpid-server/logs/system.log
Postgres Server	8084	/opt/apigee/var/log/edge-postgres-server/logs/system.log

Enable debug logging for Edge SSO

To enable debug logging for Edge SSO:

Edit the /opt/apigee/customer/application/sso.properties file (if the file does not exist, create it):
```
> vi /opt/apigee/customer/application/sso.properties
```
Set the following property and save the file:
```
conf_logback_log_level=DEBUG
```

Restart Edge SSO:

> /opt/apigee/apigee-service/bin/apigee-service edge-sso restart
