Another "exciting" development. I added another interface on a different router. This one is located in Sweden. This configuration is almost identical to the setup of the NON-working interface located in Germany. Same port name, same port type, same port speed and CDR, even the portions of the mrtg.cfg file that pertain to these ports is identical (as far as I can see) except for the obvious difference of IP and port number.

The strange part, is that the one in Sweden works, the one in Germany still does not...

Are the mrtg sections for both these interfaces the same, or even slightly different? If different, can you post the respective sections of you mrtg file?

They look the same to me, but I'll post them here anyway. Doesn't hurt to have a couple extra pairs of eyes on it. One thing to note. Usually, with the way these routers are configured, we monitor the sub-interfaces (in this case Se0/1/0.100), rather than the physical interfaces (Se0/1/0) because the sub-interfaces are configured for whatever CDR we pay for, while the port is configured slightly differently. On the working router, the sub-interface is the one that we added, and it's working fine. I logged into the Germany router (the one that isn't working) to look at the ports, and the sub-interface says it's not passing traffic, but the physical interface is. I thought that might have been my problem so I added the physical interface instead, but it still didn't work. A "sh int Se0/1/0" on the router itself shows that it definitely is passing traffic, though.

This may take a bit of work but can you post your entire mrtg.cfg? If you have multiple configs please post the config with the broken interface checks, and also post the first bit of the main mrtg.cfg up until the first interface starts. Thanks!

Yeah that did take a while, heh. Here is the full mrtg.cfg with company info removed. The NON-working router is the last entry in the config, and I have added a comment where the config for that router begins. I had to upload as an attachment as it's to many characters to post.

OK, so, we have a script that has been already setup and ready to properly parse out configs and separate them for mrtg optimization. I will do some quick testing this weekend and ship it off to you, but presently your config is still just going to be one gigantic config by the time you are done, fyi.

I'm confused what you mean by this:

Do you mean you have a script that is going to optimize my current mrtg config, but that we will have to live with it the way it is until I hear back from you? If that's the case, that's not a problem at all. Or are you saying that the script that is writing the mrtg.cfg file is already setup to optimize the format of the config?

This is only a small portion of what we will be adding overall, I just stopped here when I ran into an issue. If you mean that, in general, our config file will end up being gigantic by the time we are done, I have also already prepared for that. Until a better solution to mrtg is created, this is what we're planning to deal with. If need be, I'll break it up into multiple mrtg.cfg files so I don't run into issues further down the road. Also, I appreciate all the help from everyone so far. These forums have yet to let me down, so thanks for that.

Yes the script will break up your configurations for you so they are checked separately. I think Spenser is still working on it.
