### 3.6 Troubleshooting

Flymake uses a simple logging facility for indicating important points in the control flow. The logging facility sends logging messages to the `*Messages*` buffer. The information logged can be used for resolving various problems related to Flymake.

Logging output is controlled by the `flymake-log-level` variable. `3` is the most verbose level, and `-1` switches logging off.
