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.

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.

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 10 (350 MGz, 512 MB RAM)

Thanks!
