iostat and I/O bottleneck

[lai56]

which output of command iostat can indicate there is an I/O bottleneck in the system?

tks

there is no iostat -indicatemethebottleneck; iostat can display servicetimes, it is your busines to find out which device is slow, therefore I use 'iostat -xn' if you run this several times you might find the bottleneck
