Server logs, Server ID, and system info
The System Info page is found at Administration > System. It gives you access to detailed information on the state of your SonarQube instance.
You can browse details about your running instance on this page.
If you have a support contract, you might be asked by a support representative to send in your system info, which can be downloaded using the Download System Info button at the top.
If you want to switch to a paid SonarQube edition, you will be asked by your sales representative to send in your Server ID.
Your server ID can be found at the top of the page Administration > System.
If you’re running a commercial instance, you can also find this value on the License page (Administration > Configuration > License Manager)
The following log files are created (log files rotate on a regular basis):
- One per SonarQube process.
- The access log.
- The deprecation log which stores the Web API requests that use deprecated Web API endpoints or parameters.
If you have a support contract, you can download your instance's current log files from the UI. To do so:
- Go to Administration > System and click Download logs in the top right corner.
Server-side logging is controlled by properties set in
<sonarqubeHome>/conf/sonar.properties. The standard output of SonarQube logs can be converted to JSON with the environment variable
SONAR_LOG_JSONOUTPUT=true. A configuration of the log format is currently not possible.
The server-side log level can be customized via the
sonar.log.level property in
<sonarqubeHome>/conf/sonar.properties. Supported values are:
INFO: The default.
DEBUG: For advanced logs. Starting from this log level, some personal user information can be logged.
TRACE: Show advanced logs and all SQL and ElasticSearch requests.
TRACElevel logging slows down the server environment, and should be used only for tracking web request performance problems.
You can tune the log level via controls at the top of the page Administration > System. Changes made here are temporary, and last only until the next time the instance is restarted, at which point the level will be reset to the more permanent value set in
sonar.properties. Regardless, if you change your log level from
INFO, be sure to change it back as soon as is practical; log files can get very large very quickly at lower log levels.
The server-side log level can be adjusted more precisely for the four processes of SonarQube server via the following properties:
sonar.log.level.app: for the Main process of SonarQube (aka WrapperSimpleApp, the bootstrapper process starting the 3 others)
sonar.log.level.web: for the WebServer
sonar.log.level.ce: for the ComputeEngineServer
sonar.log.level.es: for the SearchServer
To control log rolling, use the
time:[value]: for time-based rotation. For example, use
time:yyyy-MM-ddfor daily rotation, and
time:yyyy-MMfor monthly rotation.
size:[value]: for size-based rotation. For example,
none: for no rotation. Typically this would be used when logs are handled by an external system like logrotate.
sonar.log.maxFiles is the maximum number of files to keep. This property is ignored if
The number of Lines of Code (for licensing purposes) in an instance can be found in the System section of the System Info page and on the License page (Administration > Configuration > License Manager) in commercial editions.
