CIS (Controller) Additional Troubleshooting

• AS3 Log level: A new command-line option was introduced in Controller v1.12 that logs the AS3 error response. Add below to the arguments block in the Controller deployment manifest file. The logs will appear in the Controller pod logs

"--log-as3-response=true",

• BIG-IP restnoded logs: There are two key daemons responsible for iControl REST and iControl LX Extensions. The two logs for these daemons are:

/var/log/restjavad.0.log

/var/log/restnoded/restnoded.log

• AS3 Declaration Validator: If you are using Microsoft Visual Studio Code, you can follow instructions below to install a validator for your declaration. This will identify syntax errors and do auto tab complete. Make sure to save the file first as .json extension.
