I am currently upgrading a server from Ubuntu 13.10 to 14.04. Building the 14.04 server from scratch and just moving data over to it.
Problem I am seeing is munin keeps giving me warning of Disk latency per device on the 14.04 server currently not under any load.
Disk latency per device Graphs shows on 14.04 cur min avg max VDA 11.25 366.56n 18.20 43.37
13.10 server under load cur min avg max VDA 222.42u 142.09u 1.44m 25.53m
for Average latency for dev/vda 14.04 I am just going to show average so far
Device IO Time 309.27u IO Wait Time 18.29 Read IO wait time 10.15 Write IO wait time 21.53
for Average latency for dev/vda 13.10 I am just going to show average so far
Device IO Time 209.54u IO Wait Time 1.43m Read IO wait time 318.84u Write IO wait time 7.95m
ioping currently shows about 260u on both servers.
Is this just a munin bug or do I have a problem. If bug how do I fix it?
