We have 150 hosts. Switches, servers and routers. 6 operators too.

We're using a pair of P4 2.8 GHz machines with 1GB of memory.

You've obviously never tried to run other NMSes :)

RE: CPU usage

We're running JFF on a 1.5 Ghz laptop with 512MB of RAM; it's monitoring
over 700 interfaces (about 75 hosts, including a couple of 7200's that
have about 150+ interfaces each).  We're running Fedora Core 3 on the
box.  The box runs between 30-50% CPU usage, with a few spikes into the
high 50's.

Sounds like there might be something else going on with the
machine...maybe dig into which processes are using up that much CPU and
seeing if there's something not right there?

Thanks,

Sizing of servers

Hello,
  We are often getting queries on the email list about what sort of
servers are required for such and such number of hosts or interfaces.

I was going to put a section in the documentation giving some examples
of real-world implementations so that others know what people are using
and what sort of performance they could expect.

So if, possible, probably direct to me, could people send some metrics?
Things that would be useful would be:
 Monitored Hosts:
 Monitored Interfaces:
 CPU:
 Memory:
 Disks: (just the type, sata, scsi or ide)
 OS:
 Load: (5 minute average, across say a week, or cpu%)

For one installation I'm aware of it would be

CPU			Memory	Disks	Hosts	Interfaces	OS				Load
P4 2.8 GHz	1GB		SATA	150		2000		Debian sarge	5avg max 2
Database and pollers on separate identical servers.

I'll compilie the lot into one chunk and send it to the list and put
it in the documents.

 - Craig

Slow accessing Reports

Hi guys, sorry if this has already been covered, but I
couldn't seem to find an answer in the archives.
I'm having problems with the time it takes to generate
SLA Reports.  If the report is for the last day, it
will take approximately 30 seconds.  If I try to get a
report of the last month it can take over 5 minutes
for the page to load.  Is there any way to improve
these times as I doubt my users will bother waiting so
long.  By the way I've checked the processes using top
and can't seem to spot anything unusual.

Thanks again.
Matt.

Using php5 by any chance?

Go for php4...although php5 has a setting for it but seems to ignore.

No rrd updates for serial interfaces

evnin'

Anybody has an idea why rrd files for serial interfaces
on Ciscos aren't updated?

All other interfaces are..like ethernet/fast/giga/pos etc.

jffnms-0.8.2
rrdtool-1.0.49
php-4.4.0

But multilink ppp interfaces are drawn (from channelized e3)
