Thanks for the detailed reply. As you said , I installed the MRTG on Sun
Server and said 'now what'? The reason why I don't know how to use the
udc-snmp and the Cisco mibs is may be I have do a little bit of study on
snmp, like using the snmp command line instructions. I went through the
list-archive and found almost everyone on the list using the OIDs to get
what they want. I didn't get as to how do you use these OID's in the when
you are building your mrtg.cfg file and How do I get these oid's for the
equipments I am using like the E220Rs and Cisco 3660 Access servers. 

As you have said can I build different .cfg files and take everything and do
a cut and paste to a single .cfg file and run the 'mrtg' command to build a
single page where I will get everything? Basically I am missing the first
step from where I need to start and I can carry on from there. Your mail
made me realize that building this is not easy as I had thought. 

Thanks again.

There is plenty of good documentation, it is sometimes hard to find that for

which you  are looking.

In the US, we have a toy called "Tinker Toys." It is a canister full of 
blocks and stick that you can interconnect. You can build whatever you can 
imagine with the blocks and sticks. But there are very few blueprints of 
"this is how you build a transporter."

The same is true with SNMP mibs and MRTG. You have the tools to build what 
ever you want. The creativity is in deciding what do you want to build. The 
creativity is also the hardest part.

Most of the documentation takes a newbie up to the point of getting MRTG up 
and running but doesn't address the question of "now what do I do?" This is 
where the creativity of deciding what you want to "build" comes in.

Some people use cfgmaker and create a seperate .cfg file for each monitored 
device. Or you can combine devices in one larger .cfg file. You can also use

the "Directory" directive to organize your monitored devices into logical 
groupings. I'm showing my ignorance here, because I've never used 
indexmaker, but a lot of people use it to create index pages. You can also 
have different .cfg files that MRTG uses to poll than those that a display 
program like 14all uses. I've found that  organizing the .cfg files and the 
directory structure is a trial and error process.

You really don't need Net-snmp (formerly UCD-snmp) or the Cisco MIB files to

run MRTG. They are very handy in snooping around different agents to see 
what you could see and figuring out what you want to monitor. But, most 
people doing this work wouldn't try to live without them. You can put them 
anywhere you have the free disk space. I will warn you that using them is an

art and can be tricky. There is a whole other mailing list for Net-snmp. 
There is a similar Windows tool called getif 

Congratulations on getting MRTG up and running. Now the creative fun begins.

Good Luck!
