For the past month my Cent 5.6 server has suffered random I/O spikes that last from several minutes to many hours. I'm struggling to find the ideal tool to help track down the culprit, and hope the users here can offer some suggestions.
I've got Webmin installed which tells me basic I/O usage in %, but stops short of pointing out process I/O usage. I've also installed Cacti, but it doesn't appear I can run down the problem with it either. Using the vmstat command (vmstat 1 10) tells me almost nothing useful.
Please offer some guidance.
