Hi Steve,

I have seen the options that you mention below in the documentation, but I haven't managed to make any changes to the Targets menu.

I tried changing the cfgmaker by using --ifdesc=descr or --ifdesc=alias or --ifdesc=name and changed the ifdefault on routers2.conf to ifdefault = cfgmaker, but there is no change to the Targets menu.
If you look at the pasted information on Interface 1281 on my previous email, the only location where there is reference to the configured Interface description on the Foundry switch is:
<td>Description:</td>
<td>v255 Testing node </td>
It's the wording 'Testing node' that I want to appear on the menu.

I finally managed to get the description manually changed using option 1 below. That is I added a line in the mrtg.cfg file, below the Target as follows:
routers.cgi*ShortDesc[172.xx.xx.202_1281]: xxxx
That might be my last option, as it will take for ever to change over 1000 interfaces. Or can this be done while creating the mrtg.cfg with cfgmaker??

At the moment I think routers2 uses your option 2 below to create the menu. The problem is that the MRTG_INT_DESCR is not the actual description configured on the interface but the description that MRTG retrieves from the router which is e.g. GigabitEthernet 1/1 or ve255.

Finally I don't know how I would use 3. Title[]: xxxxx other stuff. The line already exists in the mrtg.cfg file but it's not used to create the menu.

Thanks for your help and quick response!

Regards,

Tony

We also monitor foundry load balancer switches here. In fact, I have a nifty check script check_foundry which will extract active and total connections for a given vServer (it also does pServer checks for Nagios) and then graph these as a stacked area. I’ve attached a copy of an example graph image.



To put your interface descriptions on the Targets menu, you need to use one of the following methods (in order of Routers2 preference)

1. routers.cgi*ShortDesc[]: xxxx

2. SetEnv[]: MRTG_INT_DESCR=”xxxxx”

3. It uses the IP address if known

3. Title[]: xxxxx other stuff



You can also set the ifdefault option in the routers2.conf to change the way routers2 decides on a default Targets menu label.



When you use cfgmaker to generate the configuration files, if you use the --ifdesc= option you can specify a different default to put in the configuration file. It looks like you are getting --ifdesc=name, but you might want to try --ifdesc=descr or --ifdesc=alias to see if this is more what you want.



I know documentation on all this is a bit weak. I’ve a new book in production with lots of detail on MRTG/RRD/Routers2 that will help people – if you attend the LISA08 conference I’m going to have advance copies there at cost. There’s also goingto be more detailed online documentation.

Hi Steve,



Thanks for your work on routers2.

I have set up mrtg, rrdtool and routers2 although the devices I am monitoring are a number of Foundry switches with a couple of hundred interfaces each. What I want to get working, is to have an easy way of putting the interface descriptions to the left/right hand 'targets' window/frame on internet exlporer. At the moment I am getting the interface numbers i.e. GigabitEthernet1, 2, 3 etc. In our organization, this is of no use to anyone who is trying to find info on a system connected to the Foundry switch.

I found some reference on the how to, the mailing lists and the examples, but I feel I am still far from making this work.

Here is the extract of an interface from my mrtg.cfg configuration:



### Interface 1281 >> Descr: 'v255' | Name: 've255' | Ip: '10.130.4.252' | Eth: '' ###



Target[172.xx.xx.202_1281]: 1281:d0NoTr3aD@172.16.20.202:
SetEnv[172.xx.xx.202_1281]: MRTG_INT_IP="10.xx.xx.252" MRTG_INT_DESCR="v255"
MaxBytes[172.xx.xx.202_1281]: 125000000
Title[172.xx.xx.202_1281]: Traffic Analysis for 1281 -- UK1-ESW-01
PageTop[172.xx.xx.202_1281]: <h1>Traffic Analysis for 1281 -- UK1-ESW-01</h1>



<div id="sysdetails">
<table>
<tr>
<td>System:</td>
<td>UK1-ESW-01 in London Hosting Centre</td>
</tr>
<tr>
<td>Maintainer:</td>
<td>Anthony Hassiotis </td>
</tr>
<tr>
<td>Description:</td>
<td>v255 Testing node </td>
</tr>
<tr>
<td>ifType:</td>
<td>Layer 2 Virtual LAN using 802.1Q (135)</td>
</tr>
<tr>
<td>ifName:</td>
<td>ve255</td>
</tr>
<tr>
<td>Max Speed:</td>
<td>125.0 MBytes/s</td>
</tr>
<tr>
<td>Ip:</td>
<td>10.130.4.252 ()</td>
</tr>
</table>
</div>

Probably the best way to achieve what you want is to use a cfgmaker template to add the routers.cgi*ShortDesc[] directive, setting the menu link label to be exactly what you want.

I will try to get a working template posted here shortly.
