[SOLVED] Change colour of links (not using bandwidth)

[pbickerd]

Hi all,

I have a weathermap set up to monitor the number of active users on a number of sites that I look after.

On this particular map the links are not showing bandwidth but pulling information from an rrd that I set up. I want these links to change colour based on the ammount of sessions. I have set up a scale (and tried using the default but they just wont change colour. I am guessing this is because the code here that changes the colour of these lines is always looking for in:out?

To test this I currently have the node labels changing colour based on the criteria i want. Is there a way to get the links to do this instead?

I am on version 0.941.

I have attached a pic of the map as it is now.

Here is my config:

# That's All Folks!

[Howie]

I think that's working as you want, except:

* you have set the default link bandwidth to 500M. So any session counts will be turned into percentages of 500M. 4/500M is a very small number.

* you are using the default SCALE which has no colour defined for values between 0% and 1%, which is why you get white for this (very nearly) 0% value.

So what you should probably do is set the BANDWIDTH to be the maximum number of sessions on your device, and add a USESCALE sessions to use your nice 0-100 scale.

I can see that it's a little weird to think about. It makes it more logical if you use MAXVALUE instead of BANDWIDTH. It does exactly the same thing, but it makes more sense to think about it.

[pbickerd]

Sorry I should have mentioned what i have already tried.

I did try setting:

BANDWIDTH 100M
USESCALE sessions

On the VGFO-RGS link but it still stayed white. I would have expected at least purple (which is 0 on the sessions scale).

But thinking about it. Would this mean 24M/100M or is it comming up with something like 24bits/100m? I think this is the problem..

If i expect the max number of sesions to be 100, what will the bandwidth need to be set to? Even if i set it to 1k will it stil be calculating 24/1000?

Now on the Node itself I have it using the scale and it does change colour.

Thanks for your reply.

[pbickerd]

Fixed it!!!

Thanks very much for your help. I was being a dumb ass!

I changed the settings in LINK DEFAULT as follows:

LINK DEFAULT
BWLABEL bits
BANDWIDTH 0.1K
USESCALE sessions

And now it works. It gives me a scale of 0-100 matching up with 0-100%.

Thankyou again! I am loving weathermap so far. Really nice tool!

Here is a pic of the working (but not finished) product!.

[Howie]

Yes, for a NODE, the default 'BANDWIDTH' is 100, so 1 'something'=> 1%, which is why that worked for you. For links, you can force that same situation with BANDWIDTH 100 as you have, but be aware that if you get 105 sessions, it will clip that down to 100% because internally weathermap still thinks of an absolute maximum.

So the right way really is to make your scale in terms of percentages, as it should be, and set BANDWIDTH to the actual maximum session count. If that is 100, then it all turns out nicely
