7.1 Debugging a Deployment

If you experience errors when deploying services, use the following information to help debug the issue.

(Optional) Remove the services that are currently deployed on the target node(s).
It is cleaner to remove services before attempting a redeployment. See Section 5.4, “Removing Services”.
Redeploy services with debug output.
The kollacli command has the following options which can be used for debugging purposes.
-v, --verbose
This option controls the verbosity of the output. You repeat the v, to increase the verbosity, so -vv gives you more than -v, and -vvv gives you more than -vv.
--debug
This option enables the display of traceback on errors.
--log-file
This option enables you capture output to a log file, appending content if the file already exists.
To deploy with increased verbosity:
```
$ kollacli deploy -vv
```
To deploy with increased verbosity, with traceback on errors, and logging output to a file:
```
$ kollacli deploy -vvv --debug --log-file log-out.txt
```
If you are unable to resolve the issue, you might need to gather the log files (see Section 7.3, “Collecting the Log Files”) and contact Oracle Support.
