[mrtg] Re: One config & per customer access

Thu Apr 3 22:07:54 MEST 2003

80 hosts in one config file! How do you manage it?

The way we do it is like this:

\data
	\clients
		\client1 --All the .rrd & .html files are here
			\mrtg - contains the mrtg.cfg files one per device

		\client2
			\mrtg
		\and so on...

I have one cfg file per device. Much easier to manage and easier to distinguish what you are actually looking at when you view the graphs.
In the \clients directory I have an index.html with links to all the client directories. In each client dir. I have a .htaccess for basic authentication. This allows a single client to come in and see only their data. I also have a customized index.html in each client directory. These contain links to each of the clients' devices via the 14all.cgi.

14all takes some time to load all the graphs, but it's only tough when looking at the big switches that have a lot of interfaces. Routers and firewalls are not an issue.

We have about 18 clients and 80 devices. No idea how many individual "targets." A small shit-load load I suppose.

This is running on a Compaq DL360 1.4Ghz.

I hope this helps.

Subject: [mrtg] One config & per customer access

Hi,

I know this was disussed several times but I found no real solution for me from reading the archives, sorry. The explanation is getting quite long, I'll try to make it as clear as possible..
Currently I have 
- ONE big mrtg config-file with approx. 80 individual hosts and about 900 targets 
- using mrtg 2.9.25 with rrdtool
- RH-Linux 7.1 on a Dual PIII 866, 256 MB
- mostly using mrtg-rrd.cgi (0.5/0.6) for displaying graphs
- Apache 1.3.27 with basic-authentication
- each host has it's own "Directory" (by hostname) and most graphs are in subdirectorys underneath the hosts, which makes viewing/browse quick and clear; 
I'm quite happy this is all working fine so far ;)

Now, I want wo give some customers access view "their" hosts' graphs, customers can be seperated easily by hostnames/diectorys (customer1=host2,host3,host6; customer2=host1,host7 etc.) and here I'm, stuck; I wonder what you guys are doing ?
- 14all.cgi: is no option, I don't like the graphs it creates, it's very slow and eats up my CPU's (is it normal 14all.cgi takes 25 secs for 8 graphs on this box killing up almost both cpu's ??)

- routers2.cgi: I haven't managed to configure it to display all my hosts as devices correctly without splitting up the config-file to one config-file for each host. I've set "routerdefault = hostname" and played around with most config-options, but still get only the first device from each cfg under devices and then all graphs together in a list (you could imagine how this looks like with 900 targets)..
Is there any way to make it work without splitting-up the config to "one-each-host" ?
Otherwise I think it would work because of the Username- option in config is quite what I look for.
If I split the config up, how would you suggest to arrange it (subdirs?) to make access-control as easy as possible for apache/routers2.cgi ?

- Finally mrtg-rrd.cgi: I like the graphs and everything else, the only "bug" is it doesn't display subdirectory underneath a host directory but this could be (hopefully) fixed with my little perl know-how if nescessary ;). But I have see no chance to seperate display by customer (the only option I see is to create one mrtg-rrd_customer.cgi with sepearte cfg-file for each customer which makes things quite complicated for operation/changes)

All in all, is there a suggestion for a combination of MRTG-RRD displaying graphs quickly on Apache with Basic-auth (not many concurrent users viewing them) while handling with an as least complex config as possible when changing something ? (currently I see I'd have to change 10 config/cgi-files in 5 directorys for one customer and restart 3 deamons ;)

Are there any good frontends with quite "original-mrtg-like" output requiring few to no own configuration (besides mrtg.cfg) that I've missed ? I also looked at cati but this seems even more complex..

Thanks for any comments.
