Specifying a monitor log directory

The log2file filter’s log path is defined as

platformio/platformio-core/blob/7aaa9c028bcb1c1af650b4a81096764a1de0ac57/platformio/device/monitor/filters/log2file.py#L29-L36


      
          def __call__(self):
              log_file_name = "platformio-device-monitor-%s.log" % datetime.now().strftime(
                  "%y%m%d-%H%M%S"
              )
              print("--- Logging an output to %s" % os.path.abspath(log_file_name))
              # pylint: disable=consider-using-with
              self._log_fp = io.open(log_file_name, "w", encoding="utf-8")
              return self

so it will always log to the <current directory>/platformio-device-monitor-<data>.log file. If you want to log to a different directory, you woudl have to change <current directory> by invoking the PlatformIO monitor / run command from a different folder.

cd /logs
pio run -d <your original project path> -t monitor
