Non-distinguishable logging calls

Reports SLF4J, Log4j2 logging calls in one class, such as"message: {}", key) with similar log messages. These calls can be non-distinguishable from each other, and this introduces difficulties to understand where a certain log message is coming from.

Example (for Java):

private static void request1(String text) {"Message: {}", text); //similar call doSomething1(); } private static void request2(int i) {"Message: {}", i); //similar call doSomething2(); }

Locating this inspection


Can be used to locate inspection in e.g. Qodana configuration files, where you can quickly enable or disable it, or adjust its settings.

Via Settings dialog

Path to the inspection settings via IntelliJ Platform IDE Settings dialog, when you need to adjust inspection settings directly from your IDE.

Settings or Preferences | Editor | Inspections | JVM languages | Logging

  • Use the Minimum length of a similar sequence option to set the minimum length of similar sequences after which calls will be reported

  • Use the Do not report calls with the 'error' log level option to ignore messages with `error` log level and when there is an exception. It may be useful to hide the warnings, because call sites can still be located using stack traces
