A log information collection system includes a first storage device, to-be-monitored devices each including a second memory, a monitor device including a third processor, and a management device including a fourth processor. The third processor is configured to allocate a storage region of the first storage device to each of the to-be-monitored devices and control each of the to-be-monitored devices to copy first log information among log information stored in the second memory to the allocated storage region. The fourth processor is configured to collect the first log information stored in the first storage device, when a failure occurred in any of the to-be-monitored devices is detected, by accessing a second storage device to which the first log information is copied from the first storage device or by accessing the first storage device through a first access channel established between the management device and the first storage device.
