An information processing apparatus includes a memory that stores on a storage unit a log related to an operation performed on a device that is a monitoring target, and an instruction unit that, if a fault occurs in the monitoring target device in response to an operation performed by an operator, gives an instruction to the memory to change an amount of memory of the log stored on the memory from a first amount of memory to a second amount of memory different from the first amount of memory, and if the fault re-occurs in response to the operation subsequent to the instruction, instructs the memory to change the amount of memory of the log from the second amount of memory back to the first amount of memory.
