ESXTOP and troubleshoot latency on an ISCSI network

9 February 2009

Run esxtop on the console or putty session by typing in ‘ESXTOP’
Press ‘U’ to bring up the disks/LUN’s attached to the host
Now type ‘F’ to display field to add/remove
Now type ‘H’ to enable ‘LATSTATS = Latency stats (ms)’.  You will see a star appear to the left hand side of the line.  Once you see the star press ‘enter’.
Look for the column labelled DAVG/cmd.  This figure should be below 100 but I have seen this recently at 2000 which is really bad!
