Line 163 in 0cf81c3

"query": "SELECT latest(usec_per_read_op)/1024 as 'I/O Read latency',latest(usec_per_write_op)/1024 as 'I/O Write latency' FROM purePerf TIMESERIES AUTO EXTRAPOLATE "

the formula should be:

latest(usec_per_read_op)/1000
latest(usec_per_write_op)/1000

rather than

latest(usec_per_read_op)/1024
latest(usec_per_write_op)/1024
