Estimating hardware needs for Hobbit server
list Dave Haertig
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. Regards, Henrik

If you put hobbit on that E420R, you'll have more then enough to monitor your environment. I have my hobbit server on an HP- RP5400 2x540 MHz - 6 GB ram. I'm monitoring 311 "hosts" (90 printers, 12 HPUX/Linux machines and the windows servers). The hobbit server has been averaging 54% idle and a .7 load over the last 4 months. Most of the monitoring on the windows servers is not via the hobbit client but via SNMP walking the HP Insight manager MIB on the windows server. So the hobbit server is doing most of that work. .....Bruce

I'm hosting Hobbit on a 420R right now, monitoring 500+ hosts - 1gb RAM 2x 450-MHz cpu's. On this server, the Hobbit server, client binaries and data files are all NFS-mounted. In our environment, the system is clustered but everything normally runs on one side (this box). Nineteen of the monitored systems have the client installed, set up to report all default data (test columns) plus two custom tests. The same 420R also runs HPOV SNMP discovery (Network Node Manager 6.1) since I can't convince the powers that-be to drop that expensive product, even though hobbit + devmon will do nearly all of what we use hpov for in our environment; Veritas Cluster 4.1; a small custom-written in-house application; two small static web sites (in addition to the Hobbit dynamic web site); a number of small cron job perl and shell scripts; and daily rsync jobs of /etc/aliases, a custom scripts directory, and a couple of ".profile" files. The system only has 1gb of physical RAM, and uses nearly all of that all the time (but that doesn't cause any problems on the Solaris OS). CPU utilization is usually well under 10%, with occasional spikes to 15-18%. In my experience a 420-R should be more than enough muscle to run Hobbit, even in a fairly complex environment with several hundred servers monitored. Dean Casey

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). Dean Casey
