[hobbit] Estimating hardware needs for Hobbit server

[Andy France]

Hi Dave,
 
I'm running Hobbit on a Sun/Sparc/Solaris 9 box which is slightly more
up-spec (but only just!) than your options:
 
bash-3.2$ prtdiag
System Configuration: Sun Microsystems  sun4u Sun Fire V210
System clock frequency: 167 MHZ
Memory size: 512MB
 
==================================== CPUs
====================================
               E$          CPU                  CPU     Temperature
CPU  Freq      Size        Implementation       Mask    Die   Amb.
Status      Location
---  --------  ----------  -------------------  -----   ----  ----
------      --------
  0  1002 MHz  1MB         SUNW,UltraSPARC-IIIi   2.4     -     -
online      MB/P0
 
I currently monitor about 120 devices and my server is also hardly
breaking a sweat.  CPU load average is usually steady at 0.2, and it
uses about 70-80% real memory.
 
This server also runs a legacy Informix/4GL application, I use devmon to
monitor around a dozen devices, and I use a few custom shell scripts for
RRD graph generation.
 
I suspect any of the servers you listed would be fine for Hobbit in this
size deployment.
 
HTH,
Andy.

Hi -
 
I'm currently running my Hobbit server/Apache on Linux-based Dell
Dimension desktop with the following:
 
# grep MemTotal /proc/meminfo
MemTotal:      2075380 kB
# grep name /proc/cpuinfo
model name      : Intel(R) Pentium(R) 4 CPU 3.40GHz
#

It's not even breathing hard.  It's just sitting there idle for the most
part.  (CPU load 0.02, physical mem used 35%, real mem 12%, nothing ever
swapped)
 
I found some older Sun hardware in the lab that I'm considering using as
a replacement, but I don't know how it's specs would compare.  I'm not
familiar with Sun/Sparc hardware all that much.  Can anyone comment on
if what I've scrounged up might be adequate?  At most, I'd expect to
eventually monitor several dozen servers, but probably no more than 100.
 
Ultra 5
Ultra 10 (350 MGz, 512 MB RAM)
E420R (2  - 450 MHz CPUs, 2 GB RAM)
 
Thanks!
