SNMP & MRTG made in easy (Power Under Control ;)

First I have to say that this is very good and easy HOWTO. Thanks for that.

But I have a broblem. That being that mrtg doesn't generate the images for the web page. Actually it doesnt generate or have any images on the page, only the slots where they should be. Not even the mrtg advertisement at the bottom of the web page.

I did everything as told and I didn't get any errors what so ever, except "/usr/bin/mrtg: bad interpreter: No such file or directory" when running the scripts. In HOWTO there was said that ignore any errors concerning running the scripts, so I guess that it's perfectly normal? Or am I deeply lost on this one? Are those scripts the ones tha generate the images? Then I thought that maeby my snmp doesn't work, but when running this command "snmpwalk -v 1 -c public localhost IP-MIB::ipAdEntIfIndex", it showed all my ethernet ip's correctly for every ethernet devices. A bit stange is that I didn't change the snmpd.conf at all, still it did show my ip addresses correctly. Is that what it suppose to do?

Does anyone gnow what might be the broblem, have I missed something?

I'm going to answer myself to my own question.

n00b mode *ON*

That bad interpreter wans't what supposet to happen, and thank god for google. I found out that the /etc/cron.mrtg/*.sh files did have everything in same line. Of course it supposed to be that the #!/bin/sh has to be on it's own line and the rest on it's own. So here is a little pointer for those who have this same broblen and is running n00b mode *ON*.

n00b mode *OFF*

Some people pm'ed me for my mrtg cfg's and so on, so from now on I've set them online right here
With those configs you should be able to make these stats.
All credits go to whoever made parts of the config and the .sh or .pl script(s). most of it came from Google or Gentoo forums.

looking good!

I've got similar stats, just without the lm_sensor stuff.

Question: I don't see you using uptime.cfg or the mrtg-countapps.sh, any particular reason?

EDIT: looking back through this thread, I notice I haven't even thanked the author!

So I'd like to thank khazad-dum and the others in this thread for the excellent how-to!
I've been using the stats as a quick rundown of system status for a year now, and it works great!

I use mrtg-numprocs.sh instead of countapps (worked better I think)

And I dont use uptime.cfg because I couldn't set it to display monthly or yearly instead of daily (on mrtg.rootspirit.com).
When I changed the index (using indexmaker) it sets all scripts to yearly instead of only the uptime script.

That explains why I couldn't quickly determine what new functionality countapps would give

thanks.

Should be (4 typo-errors):

I also recommend increasing the timeout for snmpwalking to 3 or more (retry times default to 5)...

used bits and pieces of this and it was extremely helpful, thanks.

I would want that they give all info of the net interfaces are in kb and not in bits
How to??

Sorry for my english...

Great HOW-TO!
Is there any way I can get to see the actual traffic...like which IP's I am connecting to and vice versa?

Thanks!

Hi guys. I have trouble running MRTG on my gentoo installation.

I am running apache webserver and it works fine (the docs are located at /var/www/localhost/htdocs/).

I ran through the howto described first in this post, and I got no errors at all. *EDIT* When i run /etc/cron.mrtg/traffic.sh I get this error, saying: "bash: /etc/cron.mrtg/traffic.sh: Permission denied" - but it said in the howto to ignore warnings. .."

EDIT AGAIN (sorry, ftw) - my traffic.sh was not executable.. So i CHMOD it (700), ran it three times (got warnings), and it is working just fine.

I only followed the "traffic guide" though, as this is my main interest, thus only mrtg and net-snmp have been installed. When I come to think of it, maybe this is why I have the problem I have.. I'll post this reply anyways..

When I try to use http://colonel/mrtg (as colonel is the machine name) I have the option to press "localhost_eth0 Traffic Graph" as a link. When I do that, I am being redirected to http://colonel/mrtg/localhost_eth0.html, but that file is not present at all (404 Not Found) in the mrtg folder.

I saw in the source code of the mrtg/index.html that it was supposed to be an *.png file there, as an image, but it won't be displayed (it's not present in mrtg folder either).

What have I done wrong, and what can be done to show them stats?

I have read through this MRTG guide and the other one.. Couldn't find any answers.
