|

When I run cfgmaker, cfgmaker doesn't get snmp information from servers w/ kernel 2.6. Everything is working okay, but not in 2.6 system.
Is there any issue about this?

For use with apache, I had to change everything that referred to | Code: | | /var/www/localhost/mrtg |
to
| Code: | | /var/www/localhost/htdocs/mrtg |
but otherwise it seems to work fine.
Thanks

i am trying to monitor free disk space but get errors !

so i created a /etc/mrtg/hd.cfg and put this on it:
| Code: |
WorkDir: /var/www/localhost/mrtg
LoadMIBs: /usr/share/snmp/mibs/HOST-RESOURCES-MIB.txt
Target[localhost.hd]:hrStorageSize.9&hrStorageUsed.9:public@localhost
RouterUptime[localhost.hd]: public@localhost
YLegend[localhost.hd]: DISK Utilization
Legend1[localhost.hd]: Root disk
Legend2[localhost.hd]: /usr disk
Legend3[localhost.hd]:
Legend4[localhost.hd]:
LegendI[localhost.hd]: Root disk
LegendO[localhost.hd]: /usr disk
Options[localhost.hd]: growright,gauge,nopercent
MaxBytes[localhost.hd]: 3000
Title[localhost.hd]: DISK / USAGE
PageTop[localhost.hd]: <H1>DISK / Usage</H1>
ShortLegend[localhost.hd]: B
kMG[localhost.hd]: k,M,G,T,P
kilo[localhost.hd]: 1024
|
i dont get what i would like to have and actually i dont really know how to do this i would prefer maybe to have disk usage percentage ! if someone has an idea

|
|
First, thanks for a nice howto!
All my scripts except cpu.sh works fine, I get this error when run:
ERROR: Target[localhost.cpu][_IN_] ' $target->[0]{$mode} + ssCpuRawSystem.0&ssCpuRawSystem.' (warn): Ambiguous use of & resolved as operator & at (eval 6) line 1.
Anyone know what may cause this?
I use the same settings as in the howto with the exception of the workdir |

EDIT
I fixed it, thank you!
This line:
| Code: | Target[localhost.cpu]:ssCpuRawUser.0&ssCpuRawUser.0:public@localhost + ssCpuRawSystem.0&ssCpuRawSystem.
0:public@localhost + ssCpuRawNice.0&ssCpuRawNice.0:public@localhost |
Should be like this:
| Code: | Target[localhost.cpu]:ssCpuRawUser.0&ssCpuRawUser.0:public@localhost + ssCpuRawSystem.0&ssCpuRawSystem.0:public@localhost + ssCpuRawNice.0&ssCpuRawNice.0:public@localhost

Thanks for the wonderful how-to! I've always wanted to get MRTG up and running, but unfortunately I'm still having some basic problems after following your instructions. I think they're way back in snmpd.
I followed all your instructions, replacing only the work-dir in your examples to a different apache directory, but here's the error I get for cpu.sh (I get almost identical errors for mem.sh and swap.sh - traffic.sh and ping.sh seem to work).
| Code: |

Also related I'm sure, but I get a similar error running the cfgmaker command, which basically generates a useless traffic.cfg file for me:
| Code: |
#/usr/bin/cfgmaker --output=/etc/mrtg/traffic.cfg --ifdesc=ip --ifref=descr --global "WorkDir: /home/www/pub/admin/mrtg" --global "Options[_]: bits,growright" public@localhost

|
Sorry for such a newbie question, but I'm not at all familiar with SNMP. There's nothing in my syslog from snmpd, nor in /var/log/net-snmpd.log.
Any ideas? |

the how to is great, thanks.
I've done a script to automatize the adding of a new computer when monitoring many of them.
make free to download/use and submit critics/suggestions
here it is
enjoy.

How bad... Translate the script it into english and I will translate into german if you wish
I'd like to add a question: While making the index-page i get to following error:
| Code: |

Any suggestions?

It _does_ exist. It contains also all files except the one that should analyze traffic. I have no clue...

Hello,
I supose that:
Object required:
* [net-analyzer/net-snmp]
* [media-libs/libgd]
* [net-analyzer/mrtg]
* [sys-apps/dcron]
That you need to:
emerge net-analyzer/net-snmp
emerge media-libs/libgd (Could not be found!)
emerge net-analyzer/mrtg
emerge sys-apps/dcron
Everything works (no errors) but still notting to see

libgd doesn't exist, indeed
type `emerge gd` instead.

Here is mine.
swap, ram and hdd give bad results?
"1kb swap" and in free -m it shows 85mb used...
also my cpu is quite idle (nonstop 0%), this isn't correct as it should be at least have 10% load...

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? 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. So I guess it isn't that either?
Does anyone gnow what might be the broblem, have I missed something?

Great work! got it to work and even added a mysql monitor.
I would like to measure cpu temperature and fan speed as well but I have no clue how to go about it.
Any thoughts?
Thanks

I gave up on the fan speed and temperature, but now suddenly my Traffic monitor stopped working, it looks like it still measures (the numbers are there at the bottom) but the graph is not updated nor being ploted! any thoughts?
I used the exact same traffic.cfg script from the how-to above...

| I was having problems because run-parts wouldn't run any of the scripts, so I read the manpage and by default it won't run any file with a dot in the filename. Works like a charm when I renamed the scripts. Just in case anyone else has the same problem. |
