I don't understand... Do you mean that you just get grey arrows? Do you get any error message? Have you tried the --debug option?

I get just gray arrows. The message I am getting is

ReadData: Link sync-core had no valid data

When I ran --debug I get:

ReadFromRRD: Target DS names are traffic_in and traffic_out

ReadFromRRD: Our line is 1121115300: -1.#IND000000e+000 -1.#IND000000e+000

Then I tried fetch with the command line, I get data up to line #1121115000. It seem like it's grabbing the last line, how can I tell it to grab the 3 to last line? or what last line that is valid?

Howie,

I figure how to do that. Now I am getting live data. Thanks for telling me to use the --debug option. It was really helpful.

Thanks!!!!
Dave

What did you change? Is there something I need to fix? It looks like my method for matching the valid RRD output is still not right... I have a backup plan for that though.

I am using still using rrdtool 1.0 so when it was pulling the data it was thinking that the last line was good, so it took the last line instead of the good line.
ReadFromRRD: Found a good line: 1121115300: -1.#IND000000e+000 -1.#IND000000e+

So I saw the line where you comment out,
# if($col=='nan') { $dataok=0; } //this is probably needed for rrdtool > 1.0.

I added:
if($col=='-1.#IND000000e+000') { $dataok=0; } //to solve this problem, so now it ignore anything that has the -1.#IND000000e+000 value, which is the last data.

I am doing this in windows because I couldn't get gd to work in unix.

I was wondering if there is a way to draw one arrow instead of two because I am doing a ping legacy map, instead of traffic.

Thanks!

Hi,
I use Howie's weathermap. But I have a problem:
I have two backbone connection between two routers and I dont know how can I show both links.
When I try to create two links between nodes one of them is covered by other. I think that it occurs due to same position coordinate of nodes.
So I need to cornered links.
IS there any way to show both links between nodes?

Not at the moment with my map. The only solution right now would be to have two nodes for the same router. You can make one of the nodes invisible by having no label or icon for it.

The other solution is weathermap4rrd, which I believe lets you go round corners in a link.

And, i prefer to wait new version

what a pity ! Weathermap4rrd is great !

Seriously you're right Howie's tool is good too. I just confirmed that Weathermap4rrd support corner arrows.

bye

http://wotsit.thingy.com/haj/cacti/php-weathermap/

Lots of bugfixes. Lots of tweaks - font sizes, formattable timestamps & text changes, more config error warnings. There's a full changelist on the page.

Most important: weathermap.php is now just called weathermap! If you overwrite your old version, then be sure to change any scripts, otherwise you'll have half of one version, and half of another. The reason is to make it clear that the command-line script is not a 'normal' PHP page.

Also, you can now subscribe to an RSS for new releases, if you like that sort of thing. There's likely to be a 0.7 along fairly soon. This was mainly to get all the fixes that have piled up. My Real Job has calmed down a bit, so I have a few more features to put in pretty soon.

Hello Howie,

Thanks for the upgrade, will install it soon.
Are you still working on the editor too?
The Editor from weathermap4rrd is quite impressive and it would be great to have an editor like that for weathermap integrated in cacti (plugin).

Yes. I have a chunk of Javascript and CSS done for it. Now that I have a little spare time again, I hope to get back to it

Got to pay the bills somehow first though! It doesn't help that I keep adding new options and moving the goalposts.

I'm still not sure how integrated it could be with Cacti though. The Powers That Be for Cacti didn't seem very keen, and I still don't know exactly how it would fit in. The only thing I'd like is that it's possible to embed a weathermap in a Graph Tree, so that you can give it to a customer along with their normal graphs, and so that they don't have to mess around with logging in to get popups like the do now.
