Estimating hardware needs for Hobbit server
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!
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.

Ultra 5 and 10 are desktop systems. The E420 is a server-class system, but all of them are fairly old - I have all of these at work, and they were probably bought some 6-8 years ago.
But Hobbit doesn't require much hardware. My production Hobbit server is a Sun E220, which is a bit smaller than your E420. And I'm running a Hobbit installation with more than 3000 hosts monitored.
So all of these boxes have enough power to run your Hobbit setup. If you're free to choose, then I'd pick the E420 - it has some server-side goodies like RAID disks with hotswap that the other two don't have. And there's room for running a couple of heavy Hobbit add-on scripts.

Henrik is right, the 420-R definitely would be the best choice among these three - dual CPU's, dual power supplies, better network performance, ability to RAID mirror the disks, more expandability in terms of additional network cards (can even use quad ethernet cards). The SCSI disks in the 420-R usually last longer than the IDE disks in the other two machines, and the 420-R is easier to get parts for nowadays (at least in the USA).
