Iostat graphs missing line data

Hi all,

Hobbit Server 4.2.0 + all-in-one on RHEL 4 BB19c client sending iostat-bf.sh as STATUS

Iostat graph shows up on the web page and the cur,max,min and avg fields all show data greater than 0 for the root and apps disks but no lines on the graph. Other similar clients might show one or two points on the graph, but for the most part thy're blank.

Any assistance would be appreciated -Grs- Gregory R Shea EMC Corporation
