Hi Howie,

I'm working on a multicast map and I want to graph bandwith labels as packets/second instead of bits/s. I have a link like this:

LINK CORE-1-XBEAM
BWLABEL unformatted
TARGET gauge:/path/to/rra/core1_multicast_out_666.rrd:multicast_in:multicast_out
NODES CORE-1 XBEAM

The problem is that I am getting decimal numbers. Is there a way to define exact number in a bandiwth label like you can do in a LABEL or COMMENT sections with sentence like this: {link:this:bandwidth_out:%d}?

PS.:Maybe is not a bug, but using "SET link_bulge 1" only takes the percentage utilisation of traffic in and not traffic out to change the link width. IMHO will be great to take the greater percentage.

Thanks!
MSBS

It's not possible right now, but this is already in my todo list. I want to be able to have millisecond labels for latency and jitter maps. I think someone else wanted dB for S/N ratio.

I'd forgotten about that. Someone pointed it out a while ago. I'll see if I can change it to make a little more sense. I think my plan was actually to bulge each half of the link individually, since they're drawn seperately anyway.

Ok, uhmm...so set BWLABEL as none and make a NODE instead will do the trick.

Thanks Howie, your tool is awesome!

Yes, that would work. Or as you know, you can use the comments, which can take {link:this:...} stuff.

INBWLABELFORMAT (or whatever better name I come up with ) should be in either 0.93 or 0.94. I'm having fun with the new editor at the moment, so 0.93 is a little delayed.

I have solved this with a very simple patch to the weathermap classes..ok more of a hack than a solution, but here goes..

Edit "Weathermap.class.php". Near the top add:

Code:
define('FMT_PACKETS_IN',"{link:this:bandwidth_in:%d}");
define('FMT_PACKETS_OUT',"{link:this:bandwidth_out:%d}");


Underneath this:

Code:
                   if($style=='unformatted')
                    {
                        $format_in = FMT_UNFORM_IN;
                        $format_out = FMT_UNFORM_OUT;
                    }


Add this:

Code:
                    if($style=='packets')
                    {
                        $format_in = FMT_PACKETS_IN;
                        $format_out = FMT_PACKETS_OUT;
                    }


Also edit WeatherMapLink.class.php. Below this:

Code:
            if($this->labelstyle=='--' && $this->bwlabelformats[IN] == FMT_UNFORM_IN && $this->bwlabelformats[OUT] == FMT_UNFORM_OUT)
            {
                $this->labelstyle = 'unformatted';
            }



Add this:

Code:
            if($this->labelstyle=='--' && $this->bwlabelformats[IN] == FMT_PACKETS_IN && $this->bwlabelformats[OUT] == FMT_PACKETS_OUT)
            {
                $this->labelstyle = 'packets';
            }



Finally add this sort of thing to your weathermap config:

Code:
LINK DEFAULT
        BWLABEL packets


Now you get whole number values on the graph. In this example the data source is "packets per second". But if I try to print pps after the value with:

Code:
        INBWFORMAT {link:this:bandwidth_in} pps
        OUTBWFORMAT {link:this:bandwidth_out} pps


...then unfortunately this undoes the new formatting and bandwidth labels are back to decimal.

So..definitely a hack The screenshot shows both situations.

-----------------------------------

By the way, I am trying to achieve the same thing - a multicast weathermap, so I would definitely vote for this feature to be added to Weathermap. Among the many whole number values I want to put on weathermaps:

    unicast packets
    non-unicast packets
    active multicast groups
    connected wireless access points
    wireless users
    vpn users

Why wouldn't it? You changed the format to not include the %d, then you won't get integers. That's what the %d does.

You can do this without changing code just by adding this to either the DEFAULT LINK or any LINKs where you want it.
Code:

INBWFORMAT {link:this:bandwidth_in:%d} pps
        OUTBWFORMAT {link:this:bandwidth_out:%d} pps


There is no 'new feature', aside possibly from the ability to make new named formats. Next release has templates for nodes and links so even if you wanted only half of the links to have this, it's still only one line in each link, and a link template with the formatting in it (and any other formatting fonts etc too), so I don't think it's worthwhile.

Sorry dude, I just couldn't find this documented anywhere. Ideally should be here:

http://www.network-weathermap.com/manual/latest/pages/config-reference.html#NODE_TARGET

Wow, I thought it was. It should be in the advanced section under the special tokens stuff. Wierd.

My actual confusion was how you had it one place, but didn't in the other, but you're right - it's not documented

No dramas

Honestly it's just great to have such a tool where most things have already been thought of

This topic saved my life

Thanks Howie for making this great tool.

Share my usage of Weather Map with this picture.

The small pieces next to the node label (sub node) display temperature and CPU usage. (I use %d formatting to keep it tiny (7% instead of 6.802333333%(a very ugly one))
