I'm trying to monitor, over the long-term, per-process disk IO (a counter of bytes read and written per pid would be ideal). I currently monitor per pid cpu and memory usage using the SNMP Host-Resources MIB, however I don't see any oids for io (disk or otherwise) per oid. The closest I've come to finding what I want -- per-process disk IO stats -- is the Linux tool dstat -- something like "screenshot 3" at: http://dag.wieers.com/home-made/dstat/ which is the output of: dstat -c --top-cpu -d --top-bio --top-latency would be good...iostat, vmstat don't give that sort of info... any suggestions or hints? Thanks, Adi
