<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>Basically, it depends on how many Targets
you have, and whether or not you use external plugins or just SNMP checks.<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>So, if your 100 machines are being checks
for 1 network card and 1 cpu stat, that would be 200 Targets, probably using
SNMP only.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>The main bottleneck for you will be Disk
IO. You should get the fastest disks you can get as slow disk IO slows
down polling and means more threads are running, increasing memory
requirements.<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'><o:p> </o:p></span></font></p>
<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>A 200-Target installation is relatively
small. We run about 14,000 Targets on our dual-Xeon 3GHz linux server
with 4GB RAM, with still some spare capacity. You could certainly manage
with a much smaller server. If running under windows you have a slightly
higher requirement but not much.<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'><o:p> </o:p></span></font></p>
<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>Note that, for performance, you should use
MRTG with RRDtool and a frontend such as Routers2, 14all or mrtg-rrd. While
you can run in native mode, performance is far worse and you will find that you
need a much larger server to cope with the load, as in Native mode MRTG will
recreate all the graph images every 5 minutes, rather than only on demand.
A native-mode MRTG may need 10 times as many resources as an RRD-mode
installation.<o:p></o:p></span></font></p>
