Upgraded from 4.2.3 to 4.3.17 and have noticed some strange behavior that
is causing empty (broken) or extra graphs in 4.3.17 for the linux-iostat
graphs as described in
http://www.docum.org/drupal/content/linux-iotstat-graphs The linux-iostats
script has been in use for years with out issue, until the upgrade. Now
that we have upgraded to 4.3.17. There is only one iostat-disk.*.rrd file.
How is first=5&count=4 calculated? it's redundant and empty. The
first=1&count=4 is good. See debug snipit below. is tthe tps:Guage
is being counted as extra graph value? I've looked at this until my eyes
have crossed. Hoping a fresh set of eyes can point me in the right
direct.ion.
