Cannot create graphs or maps in 1.1beta6

[roger69]

When I attempt to create a graph or map, it appears to be successful, however when I try to view the graph or map, I just get the icon in my browser indicating that the image is missing.

Other aspects of 1.1beta6 are working. I have some simple checks of hosts set up and they are returning data.

I get the feeling this is a permissions issue? But I'm not sure where.

Any help appreciated.

Same for 1.1beta7

I did a complete new install of 1.1beta7 on a different Fedora Core 4 box, and have the exact same problem. Monitoring of hosts works great, but when creating graphs or maps, nothing is ever displayed.

Sounds like you might not have the php-gd package installed. Check your apache error logs to see if there are errors related to graph creation.

Bing!

You are correct sir! Apache error_log had:

[client x.x.x.x] PHP Fatal error: Call to undefined function imagecreate() in /var/www/html/zabbix/include/classes/graph.inc.php on line 634, referer: http://test/zabbix/charts.php?groupi...0027&graphid=1
[client x.x.x.x] PHP Fatal error: Call to undefined function ImageCreateFromString() in /var/www/html/zabbix/include/maps.inc.php on line 184, referer: http://test/zabbix/charts.php?groupi...0027&graphid=1

rpm -qa | grep php did not show php-gd as installed.
yum install php-gd, apachectl restart, and I have graphs.

Thanks!

Graphs

No,it's not just an issue of the GD lib, the graphs are created in the database but doesn't show up in any graph editing functions.

I try to add graphs to my template, zabbix frontend does say it has added a graph, and true enough they get into the database but they don't show up anywhere in the PHP gui.

I have tried the SQL from the graphs.php and it just doesn't return *ANYTHING*

The graphs table really DOES contain 3 graphs

graphid,name,width,height,yaxistype,yaxismin,yaxismax,templateid
1,Feed Bandwidth,900,200,0,0,100,10011
2,Feed Usage,900,200,1,0,100,10011
3,Prodsat Queues,900,200,0,0,100,10011

the presence of entries in mysql just tells the frontend that user defined graphs *exist* for any particular object and what they are.

GD is necessary for php to draw and display them.

[rickardp]

Since I have php-gd module installed I don't think that the problem is *THAT* simple, besides in all the other versions of zabbix from 1.0alpha version (yes I have been using them for a long time) just adding a graph can easily be done without GD, it's the adding of items to the graph that needs GD.

The frontend is just not showing the graphs in "configuration -> graphs" or "configuration -> Hosts -> templates -> graphs" that I know is present in the database.

Depending on your distro you may need to add the extension to your php.ini for your respective php installation (3, 4 or 5). Debian/kubuntu/ubuntu do this automatically but others may not.

I guess that GD is installed and running when the command var_dump(gd_info()); return the following info right?

So where are my maps? I have GD installed/enabled. There is a problem here, did the GD stuff really solve your problems or have you not installed 1.1beta7 and tried?

Sorry to be grumpy but zabbix 1.1beta7 is part of a company evaluation for a single monitoring platform and it doesn't look good right now for zabbix since 1.1beta2 lacks a bit in the requirements although there are a lot of adaptions made for the zabbix system running in production right now. But I really need to get the new version going.

Tested GD

Tried out GD by assembling a small php script, and it works well.

<?php
header("Content-type: image/png");
$im = @imagecreate(200, 50)
   or die("Cannot Initialize new GD image stream");
$background_color = imagecolorallocate($im, 255, 255, 255);
$text_color = imagecolorallocate($im, 233, 14, 91);
imagestring($im, 1, 80, 20,  "GD works!", $text_color);

$col1=ImageColorAllocate($im,200,200,200);
$col2=ImageColorAllocate($im,0,0,255);
ImageRectangle($im,1,1,199,49,$col2);

imagepng($im);
imagedestroy($im);
?>

Graphing

Hi rickardp,

I think you're right; theres a problem with the graphing. Only graphs showing
a week or longer show up, all the others produce broken images. Do you have
the same problem?

jono

[rickardp]

Since I have installed all from scratch I cannot even see the graphs that zabbix said I have created (and I can see in the database) in the php frontend, i have tried to cut out the SQL in the graphs.php file and run it, it doesn't return any graphs. I haven't got time to spend on this right now since I'll be away all next week.

Best regards, Rickard

rickardp is right

I see the exact same behaviour as rickardp is describing.
Go to configurations, graphs, create graph, give it a name and hit save.
You get a message saying:
Graph 'name' added
and right underneath it, it says -- No graphs defined.
It's not GD's fault since I can see 'simple graphs' w/o problems, just not custom ones.

The graphs column has the entry for the graph in mysql
mysql> select * from graphs;
+---------+------+-------+--------+-----------+----------+----------+------------+
| graphid | name | width | height | yaxistype | yaxismin | yaxismax | templateid |
+---------+------+-------+--------+-----------+----------+----------+------------+
| 5 | name | 900 | 200 | 0 | 0.0000 | 100.0000 | 0 |
+---------+------+-------+--------+-----------+----------+----------+------------+
1 row in set (0.00 sec)

Any help is appreciated. This may have something to do w/ the earlier no elastic in field list error I mentioned???
Cheers.
