Method and device for real-time monitoring of oracle monoblock read delay

The invention discloses a method and device for real-time monitoring of oracle monoblock read delay. The method comprises the steps of conducting real-time monitoring of a monoblock read event which is currently generated to obtain the read time required for completing the monoblock read event; outputting the read time. By the adoption of the technical scheme, monoblock read events generated in an oracle system are monitored in real time, and the read time for each monoblock read event is output in real time, so that working staff can obtain the monoblock read delay, namely read time, of each monoblock read event in real time. The method is different from the prior art that the average value of time for monoblock read within a period of time is used as monitored monoblock read delay and output in that the read time of each monoblock read event is output, so that working staff can acquire the read time of each monoblock read event in time, real-time monitoring of monoblock read events is achieved, and then mon
