Hi all, hope someone can help me to solve this.
I am showing a weathermap on the LCD TV in my office so we can take a look on whats going on the network.

Everything goes fine, but after an hour or so the screen scroll up and i have to adjust it again. How can a i fix this ? Im using Firefox to show the wathermaps.
I add some pics to show the problem.

What i see:

The tabs are normally missing for you?

I don't understand your pictures...

Sorry, i will try to explain it better:

If i dont manually hide the tabs the maps doesnt fit in the screen well. I take some more pics. I hide tabs using the scroll bar...

Normal view:

after some page refreshs...

I didnt know that the normal way to show the maps is including tabs.

Maybe when the cacti cut your connection and he should connect you with the guest login ?

The normal way is including tabs.

I would expect that it would refresh more often than every hour, too.

I will try to add something for the next version to do real full screen maps, for you.

You've got a lot of space on your page. Maybe you could make the height of your graphic smaller, so the picture and tabs would show, without haveing to tweek it. That's what I've done with mine.

If you manually run the rebuild php script with:
php weathermap-cacti-rebuild.php

You can see the image files that are generated. Then simply create a symbolic link from the directory to where they are stored and display that image file on your LCD. Takes cacti out of the equation. We use this .php script to cycle between a number of different urls. Work pretty well.

cycle.php code:

Code: Select all

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html lang="en">
<head>
<title></title>
<style type="text/css">
body, html { background-color:black; margin: 0; padding: 0; width: 100%; height: 100%; overflow: hidden; }
iframe { border: none; }
</style>
<script type="text/javascript">
var Dash = {
    nextIndex: 0,

    dashboards: [
        {url: "http://yourdomain.com/weathermap.png", time: 5},
        {url: "URL-2", time: 10},
        {url: "URL-3", time: 20},
        {url: "UrL-4", time: 5}
    ],

    display: function()
    {
        var dashboard = Dash.dashboards[Dash.nextIndex];
        frames["displayArea"].location.href = dashboard.url;
        Dash.nextIndex = (Dash.nextIndex + 1) % Dash.dashboards.length;
        setTimeout(Dash.display, dashboard.time * 1000);
    }
};

window.onload = Dash.display;
</script>
</head>
<body bgcolor="#000000">
<iframe name="displayArea" width="100%" height="100%"></iframe>
</body>
</html>

That will work too!

You might also need to remove/change the .htaccess file in weathermap/output/ directory, depending on which version of weathermap it is. I think some versions might block direct access from the web for that directory.

Do not know if it will help, but I had a problem by more or less similar: a large screen (3 x 1.5 m) divided between Weathermap, nagios and google maps. I made a html file and put a refresh in 120 seconds page cacti. The solution works only with Firefox and does not work with IE. When I have a restart then it appears the login screen and the tabs, but soon disappears.

This is what my symbolic link looks like, I created it in an area that a normal web user could get to.

Code: Select all

lrwxrwxrwx  1 root     root         65 2011-05-13 12:43 fund-util.png -> /var/www/cacti/plugins/weathermap/output/525b5e07e8cdd979fb16.png
