Good day, I'm fairly certain there's a problem with the ssIORawSent and ssIORawReceived counter objects on my net-snmp 5.2.1.rc2 agent, so, I think that this is the right forum to bring this up in. The agent is running on a Linux 2.6.8 host (Fedora Core 2).
It looks like the objects are switched around (and off by a factor of 2 or 3 or so). Polling the device over 5 minutes: Thu Jan 13 14:05:58 MST 2005 UCD-SNMP-MIB::ssIORawSent.0 = Counter32: 1435885920 UCD-SNMP-MIB::ssIORawReceived.0 = Counter32: 709648166 Thu Jan 13 14:10:59 MST 2005 UCD-SNMP-MIB::ssIORawSent.0 = Counter32: 1435887752 UCD-SNMP-MIB::ssIORawReceived.0 = Counter32: 709801446 ... shows ~511 blocks/s "Received from a block device" and ~6 blocks/s "Sent to a block device" (according to the MIB descriptions). Over the same period of time, vmstat shows: -bash-2.05b$ vmstat 300 procs -----------memory---------- ---swap-- -----io---- --system-- ----cpu---- r b swpd free buff cache si so bi bo in cs us sy id wa 0 0 7808 528832 58788 1702492 1 1 1 0 0 2 14 5 78 4 0 1 7808 542404 59968 1672452 0 0 3 244 1103 0 7 2 90 1 So vmstat shows 3 blocks/s "Received from a block device" and 224 blocks "Sent to a block device" (according to the vmstat man page). I am not sure of any other way to verify the quantity of blocks sent or received, but I can tell you that the device was going heavy DB writing and nearly no reading (i.e. vmstat seems to be right). The man pages suggest disk I/O data is in /proc/stat, but I don't actually see it in there. I have repeated the tests under different loads, but the results are all similar. Maybe I'm missing something here? Is there anything else that I could provide? If I knew where net-snmp gets these figures from (someplace under /proc ?) I could compare the data to what the agent reports.
