PRTG & MRTG OR OTHER SNMP APPLICATION BE ON THE SAME SERVER

Im running mrtg on a win2003 server and Im tired of having to always re-run the setup file when I update my NIC cards.  I want to test other snmp applications, like PRTG & others.
1.      Can they all be on the same server?
2.      If I need to change ports what ports would I need to change.
3.      Ive read thru all the various postings on snmp on this site and still do not have a clue as to which application gives you the most accurate information; I guess each one gives you a little something different.
4.      Im also trying to add various MIBs to my mrtg and have not come across a great tutorial how to incorporate MIBs.

Hi,

Referring to your queries;

1-   Can they all be on the same server?

Yes they can be on one server. Each will query using the UDP port 161. But it is always recommended to use one NMS rather then two which creates un-necessary traffic.

2.      If I need to change ports what ports would I need to change.?

No, you do not need to change the port.

3-     ve read thru all the various postings on snmp on this site and still do not have a clue as to which application gives you the most accurate information; I guess each one gives you a little something different.

All applications use the standard SNMP protocol. The difference comes in reporting and the graphs. Usually the open-source application need to be configured while the properity paid solutions give you easy to use Interfaces with nice graphs and almost zero configuration. But benefit of open-source is the customization which can not be done to prosperity solutions.

4-       Im also trying to add various MIBs to my mrtg and have not come across a great tutorial how to incorporate MIBs.

Elaborating on question #3:

3.      I've read thru all the various postings on snmp on this site and still do not have a clue as to which application gives you the most accurate information; I guess each one gives you a little something different.

MRTG is solely an average based reporting tool. It does not store long term raw statistics and cannot tell you exactly what traffic moved when. It is meant more as an overall observation or percentile reporting tool. MRTG by itself is not so well at tracking customized devices that are non-traffic, however, the brain of MRTG which is RRDTOOL is used by Cacti to gain this functionality (See below)

PRTG is what I call an absolute reporting tool. It can be programmed to keep raw data for any period of time you choose. You can then recreate reports on the data at your whim. Of course, this means you have to maintain the drive space to hold that data. PRTG is commerical software, however, you can download and use a 10 device licence as freeware, or up to 20 if you promote PRTG on your website.

PRTG can also import MIB's and track devices such as APC power bars.

Cacti is another open source tool that falls in the middle. It is highly customizable and can also watch non-traffic SNMP devices such as APC power bars. There is extensive support for Cacti at http://www.cacti.net/. While it is highly customizable, it can also be frustrating to setup.
