[mrtg] Re: Adding additional hosts / devices

[Peter Glanville]

I use Windows too.
I liked indexmaker, but found it better to upgrade to MRTG + RRD + 
Routers2.cgi
Follow the install routines for each section, upgrading for one host will 
entail minimal changes (RTFM)
You can use CFGmaker to create configs for each device (use a sensible 
naming convention), or create them by hand
Use a Master.cfg that invokes each of the lower level CFGs (as described 
below). Your PC invokes the Master.CFG 
Routers2 front end then show a list of Devices (ie CFG files) and when you 
drill into one, you get a list of Targets (ie interfaces or whatever 
you're monitoring), and you can drill into each for the history.
In fact, you can arrange the CFG files in a meaningful directory/folder 
structure (per building or location for instance, or grouped by hardware 
type: routers, switches, servers etc). Then you first select the folder, 
drill into the device list and then pick the Target/interface.

You can use "dummy" CFG files.
Have a CFG for collecting data, included in the Master.cfg, with the line 
"routers.cgi*Ignore: yes" which means that it does not show up in the web pages.
Then create your own CFG files (not included in Master.cfg) that has a 
selection of Targets from various Devices. This summary gets shown on the 
web, but is not any single collection CFG file.

One option, for multiple CFGs, is to use "cron" to schedule multiple jobs. 
There is a Windows (application, or service) version you can download, and 
then schedule some CFGs to run at minutes 1, 6, 11 etc, and another at 
minutes 2, 7, 12 etc, thereby reducing the cpu processing load by 
spreading the jobs. (remember to set RunAsDaemon: No)

If you want to take this further, drop me line directly

Thanks Paul.

Ok.. So I'm running this on a Windows 2003 server and have one host
running and have used indexmaker to create the index page.

To add more do I simply use the command prompt and type perl Target... ?
This is something I need to get a plain English breakdown on.

If I create individual .cfg files for each host, how does one go about
linking them back to the master? 

Can anyone spare a few minutes giving me a step by step breakdown?


Cheers.

You can do it either way.  It's much more manegable to have each
device in it's own config file IMHO.  You can stil use a single MRTG
process by having one master config file that includes the other
files.

Exampe.  master.cfg
include device1.cfg
include devicd2.cfg
...

then 'mrtg master.cfg' to start the MRTG process.
