Пытался менять параметры “poll_interval” и “read_rate_limit_ms” в wb-mqtt-serial.conf, но результата не заметил. Из оборудования у нас к нему подключены как минимум МСМ8, 9 термометров по 1-wire и MAP12E. Пробовал через веб-интерфейс отключать (снимать галочку) каналы 1w и rs485 - LA падал разве что чуть ниже 3. Возможно у нас всегда так и было. Стоит ли с этим разбираться?
В анализ дисковой активности еще не пробовал. Спасибо.
