[mrtg] Can't add any devices with cfgmaker

[Mike Gideon]

No. Interface 3 is not commented out.  That section refers to
192.191.191.21_3

 

### Interface 3 >> Descr: '3' | Name: '3' | Ip: '' | Eth:
'00-0d-9d-b5-13-7d' ###

Target[192.191.191.21_3]: 3:public at 192.191.191.21:

SetEnv[192.191.191.21_3]: MRTG_INT_IP="" MRTG_INT_DESCR="3"

 

But like I mentioned there aren't any 192.191.191.21_3 files.

 

Some of the interfaces are commented out.  Approximately half are.  I'm
guessing, those were not active when the config file was created.

Thanks Lyle,

I did  "cfgmaker --output /var/www/mrtg/192.191.191.21.cfg
public at 192.191.191.21"  and got the cfg file.  When I run indexmaker on
it "indexmaker /var/www/mrtg/192.191.191.21.cfg >
/var/www/mrtg/index2.html"

I get a page, but that has problems. It looks like it tried to create a
graph for each interface it found. It looks as if it tried to create a
page /var/www/mrtg/192.191.191.21_3.html, and  192.191.191.21_6.html etc
etc, but there aren't any 192.191.191.21_#.html files anywhere. The
hyperlink looks right http://myserver/mrtg/

192.191.191.21_3.html.  

 

Does it appear like I still don't have the cfgmaker right or is it
something with indexmaker?

 

 

 

Are there # symbols at the front of those lines in the config files?



 

What is a good way to organize many devices?  I was thinking of building
a cfg directory under the mrtg. It looks like each device will have many
associated html files and that could get complicated.  Then perhaps one
master page with a link to all the individual pages I've made with
indexmaker.  What did you do?

 

No, use rrdtool and Routers2.cgi and stop rebuilding those .png files
every 5 minutes.  Huge waste of CPU cycles and severely limits the
number of devices you can monitor using mrtg.

I just installed MRTG on Ubuntu.  

It seems to be working fine.  I added my local linux with

Cfgmaker public at localhost > /etc/mrtg.cfg

 

That is running just fine, updating every 5 minutes like it is supposed
to.  I want to add more devices now but I get an error.  I try 

Cfgmaker public at 192.191.191.21 > /etc/mrtgtry2.cfg

 

It runs a bit then tells me

--base: Get Device Info on public@/etc/mrtgtry2.cfg:

Error:

I can run snmpwalk and get info back:

snmpwalk -Os -c public -v 1 192.191.191.21 system

sysContact.0 = STRING: 

sysName.0 = STRING: ProCurve 2650

sysLocation.0 = STRING: Server Room

sysServices.0 = INTEGER: 74

 

Cfgmaker seems to want to replace the IP addr of the device with the
-output.  

 

Am I doing something simple wrong?

Thanks in advance.

 

Try:

cfgmaker public at 192.191.191.21 -output=/etc/mrtgtry2.cfg

cfgmaker thinks the second part is a second device to poll.
