<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>1. The port number is probably the
default. The OID depends on what you want to monitor: if you want network
statistics, then MRTG will do this automatically. The community string should
be provided to you by whoever configured and maintains SNMP on the device you
are monitoring.<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'>2. Depends on the OS you are monitoring<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'>2.2, 2.3 these OIDs actually change
depending on how many storage devices are attached<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'>2.4 With SNMP, these come in the standard
location and MRTG can monitor them directly<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'>We use the nsclient agent under windows
and the mrtg-pnsclient.pl script to query it instead of using SNMP, its easier
and possibly more secure.<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'>I suggest you concentrate first on making
it work with just network traffic, and probably on network switches and
routers, before trying to monitor hosts and other host-related metrics. These
require not only more complex configuration to obtain the data but also you
have to do other additional configuration in the labels etc.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:

(network traffic) first before trying to do server monitoring<o:p></o:p></span></font></p>
