I have several FAS running DOT 8.2 7-mode and for some of them the 2 followings counters are not collected :
object type : system
counters : sys_read_latency / sys_write_latency
No errors reported into the log file
I can't seem to find supporting information for this error? Any information would be great

I have never heard of this before but perf counters collected by Harvest that have a value of 0 are not forwarded to Graphite. Could it be that these systems are idle and simply haven't had any read/write traffic yet? An easy test is to just make some read/write traffic and see if the metrics appear. Note that in the Graphite native interface you have to to do a F5 browser refresh for the tree to be updated to display new metrics files.
