  • 1.  High `uptime` numbers, even on idle system

    We're a little late in the game upgrading from AIX5.3 to 6.1, but we noticed that with the last couple ML updates to 5.3, and with 6.1 as well, we're seeing high uptime numbers even on an otherwise unloaded system. Checking vmstat shows that there is indeed 1 process in the run queue (but its vmstat)...

    We reported the issue to IBM who basically said "don't use uptime as a determination of system loading". We use the 5 minute value of uptime to report to our alerting systems...

    Anyone have a similar experience? We don't see it on all systems, but most of them. Most are sitting at 1.0 at all times.

    Thanks!

    Just for the record IMHO there is no direct relation between number of processes for 5 minutes (the number in top) and the load of the machine. Check the CPU usage
