Re: [hobbit] OSF physical memory, good reference



Henrik,

I have no access to Tru64 4.x systems...
Here are some output examples from "uptime", I have implemented a simple client script which reports the uptime to the hobbit server, every day I had a blackout for 1 hour in de RRD. I have fixed it, the reason for that was:


# date
Sun Aug  7 17:19:22 CEST 2005
# uptime
17:19  up 90 days, 56 mins,  1 user,  load average: 0.00, 0.01, 0.00

# date
Sun Aug  7 17:23:58 CEST 2005
# uptime
17:24  up 90 days, 1 hr,  1 user,  load average: 0.00, 0.00, 0.00

# date
Sun Aug  7 17:24:21 CEST 2005
# uptime
17:24  up 90 days,  1:01,  1 user,  load average: 0.02, 0.02, 0.01

==> There are 13 parameters, if uptime is some days + 1..59 mins (or 1 hr).
==> For the next 23 hours we have just 12 parameters.

Here the output on Solaris 8:
$ uptime
 5:30pm  up 8 day(s), 16:42,  1 user,  load average: 0.06, 0.02, 0.02

On Linux:
$ uptime
 7:30pm  up 8 days, 17:20,  1 user,  load average: 0.00, 0.00, 0.00

And here some outputs from "vmstat -P" from Compaq Tru64 UNIX V5.1B (Rev. 2650)
