Hello,
I'm in the proccess of setting up a new server for my Netdot installation.
I'm curious about the best way to do it and about performance compared
to others. I've read an old email where Carlos Vicente said, with
2000+ devices the -DIFAT proccess took like 50 minutes, wich seems
amazingly few time to me.
Current Setup:
Hardware: Regular desktop PC, hp compaq 8200 small form factor, 8Gb
RAM, Intel(R) Core(TM) i5-2400 CPU @ 3.10GHz, "normal" 1GB sata disk
Software: Ubuntu LTS 12.04 netdot 1.0.5-rc1 + mysql
devices monitored: 1706
Total Macs in database: 105425
The time it takes to do a updatedevices -DIFAT varies beetwen 10 and 15 hours.
After convincing everyone that Netdot is good stuff, I've been given a
real server in CPD to set it up:
New Hardware is ProLiant DL360 G7, 2 x Intel(R) Xeon(R) CPU E5649 @
2.53GHz, 16GB RAM, 2x160GB SAS disks (actually in raid0)
I have a few constraints, i have to use a God-Sent datacenter
architecture that obligues me to have a frontend and backend stuff,
throwing in some virtualization is also a must. So i'm thinking on
setting 2 virtual machines, one to run the only the database and the
other the rest (apache + polling).
On the same mail i talked about, Carlos said they use one server for
database + apache and another one for polling. So i decided to send
this message to share my thoughts, and maybe get some advice or learn
from other's experiences. With some fact backing me up, maybe i can
get rid of the virtualization and backeend-frontend stuff. Don't think
it will do any good as it all runs of the same hardware, but maybe i
should install on backend apache+mysql (apache backend lol) and on the
frontend just the polling or viceversa.
Greetings,

I saw a HUGE speed increase when I split mysql off to another box.
10-15 hours is definitely not good, likely you have some devices in there that
are not working properly. I suggest running the poller with debug and seeing
where things are hanging up. For me, we had a class of switch (old old 3com's)
that were responding EXTREMELY slow and basically halted the entire
updatedevices process.
