Switch Interface status weathermap

feds · Post by **feds** » Wed Jan 07, 2009 6:30 pm

Hi, I have been looking through this forum trying to find a way to show interface link status on a weather map with no luck.

This is what I have so far.

I am setting a background image of a cisco 6513 chassis. I want to add nodes for each of the ports and have them display a green icon for up and a red icon for down.

I have been able to get it to show a green icon for the host being up (using TARGET cactihost feature, but I can't figure out how to get this working for an interface on a host.

I am graphing the ifOperStatus for each interface. I used this link to get that working http://forums.cacti.net/about17722.html

I am using the newest version of cacti and weathermap and am running on fedora 10.

Let me know if you require any other info.

Anyone that can help, I would be very thankful

If you have ifOperStatus in an rrd, it should work almost the same as cactihost:... except you need to know a bit about specifying the target.

Your ifOperStatus rrd file won't use traffic_in or traffic_out as the DS names in the file. You can learn more about that stuff here: http://www.network-weathermap.com/node/85

You'll end up with a target something like:
TARGET gauge:/var/www/html/cacti/rra/my_operstatus_234.rrd:ifOperStatus:-

You will need to do a similar custom scale to your cactihost: one, too, of course. (IIRC, 2=down and 1=up for ifOperStatus).

Thank you for the info, I have the TARGET set correct now, and I'm not getting errors about that, but I am now getting errors about my icon missing.

Here is my conf file.

Here is the error:

01/07/2009 07:45:41 PM - WEATHERMAP: Poller[0] [Map 1] test.conf: ICON images/ports_[UNKNOWN].png does not exist, or is not readable. Check path and permissions.

Am I using the wrong syntax for the {node} command? It tried using the following:

{node:this:state}
{node:this:ifOperStatus}

Any idea?

Thanks[/quote][/code]

The value in the rrd will be a number. I think operstatus is either 1 for up or 2 for down. So, you need scale where 1 and 2 are different colours.

SCALE ifstatus 0 1.5 255 0 0
SCALE ifstatus 1.5 2.5 0 255 0

and then 'USESCALE ifstatus in' in your default node. Now the node label will change colour. To change the icon, the easiest way is to use the same SCALE again:

SCALE ifstatus 0 1.5 255 0 0 images/down.png
SCALE ifstatus 1.5 2.5 0 255 0 images/up.png

Then in the node, you can use 'ICON {node:this:inscaletag}' which will contain the text 'tag' from the SCALE line that matches for that node .

You could also create icons called state_1.png and state_2.png and use 'ICON images/state_{node:this:bandwidth_in}.png' and skip the special scale.

Thank you so much....I go it working!!

One small question, I am getting errors in my log that say file port_1.866666.png does not exist

I am using the port_{node:this:bandwidth_in}.png icon, this happens for one or two polling cycles then it picks up the correct number.

Anyone know how to fix this, I tried changing my graph template so it used last instead of average but it didn't help.

Thanks

I think you need to change your rrd definition to absolute instead of gauge. Something like that - check the rrdtool docs. It's rrdtool averaging values that causes this.

You could use {node:this:bandwidth_in:%d} to force it to an integer, but I think it always rounds down, so you'll still get the wrong value, but no error.

Thanks I have used the %d as I'm not too worried about the 1 or 2 polling cycles with a wrong icon. Just didn't want a blank spot on my weather map and an error in the log.

is where did you get bandwidth _in is it in you rra

Howie · Post by **Howie** » Fri Sep 11, 2009 4:46 pm

bandwidth_in is what weathermap calls the 'in' channel of the TARGET regardless of what the rrd file (or any other kind of target) is called. See the 'advanced topics' section in the manual about 'special tokens' for more...

Thank you....

Will try it on Monday

Help Please!!!, head against the wall!!

Before you hit your head on anything READ THE LOGS.

You didn't put a return after the POSITION for the node, so weathermap doesn't know where to put the node. There would be an error for that.

and you need a '-' for the end of the TARGET, so there are two DS names:

Code: Select all

TARGET gauge:/cacti/rra/72/425.rrd:int_status:-

there would be an error for that too.

Thank you, Thank you..... It's Finally going...

One more question.... Explorer is showing "done with errors"

at Line 107

print "<script type=\"text/javascript\" src=\"overlib.js\"></script> \n";

in weathermap-cacti-plugin.php

it seems to be complaining about my OVERLIBGRAPH settings wich is not working.. if I run the overlib link in a separate page it displays the image correctly......

Thank you again for your patience,

If IE is saying this, then it's not line 107 in the PHP, but line 107 in the *output* from the PHP - i.e. the HTML source. Do a View Source and look at line 107 of that... IE sometimes gets the line number a bit wrong though.

My guess would be that you have a node or link with a name that contains characters that aren't valid in a CSS id.
