[hobbit] Estimating hardware needs for Hobbit server

[Dean Casey]

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 5

Ultra 10 (350 MGz, 512 MB RAM)

E420R (2  - 450 MHz CPUs, 2 GB RAM)

 

Thanks!
