web monitoring graph problem

[js1]

For a couple of hosts, I'm having problems viewing the web graph. The graphs are blank, and at the bottom of the page, I see these messages:

 Undefined index: item_data[/usr/share/zabbix/httpdetails.php:184]
 Undefined index: item_data[/usr/share/zabbix/httpdetails.php:185]
 Undefined index: item_data[/usr/share/zabbix/httpdetails.php:186]
 Undefined offset: 2[/usr/share/zabbix/httpdetails.php:235]
 Undefined offset: 1[/usr/share/zabbix/httpdetails.php:244]
 Undefined offset: 2[/usr/share/zabbix/httpdetails.php:254]
 DBcondition Error: [i.itemid] =
 Undefined offset: 1[/usr/share/zabbix/httpdetails.php:254]
 DBcondition Error: [i.itemid] =

Other hosts similarly configured work just fine. What can I do to further debug this? I'm using 1.6.8.

if you look at latest data, do you see data for all web items (compare this with other hosts - preferably having the same amount of scenarios and steps) ?
if no (and maybe anyway ) try re-creating one scenario where you see such problems

The checks returns status OK.

    Name  Number of steps  State                            Last check             Status 
    Check  1               Idle till 08 Jan 2010 01:45:07   08 Jan 2010 01:43:07   OK

It's just the graphs don't draw. No speed, response time, or response code is listed.



Our next step was to remove the web check and recreate them.

quick idea - check timezone set on the server (php parameter), and time sync of the client and server

Hello,

Sorry for refreshing this topic but I have the same problem.

I have 2 nodes zabbix server Master and Slave. From slave server I check website. When I check website graph view on master slave I have the same error and blank graph what js1, but when I check website graph view in Slave server everything is correct.

One more interesting things is that I change update interval in web scenerio on Slave server the graph on Master server is OK (but only for a moment). Any idea how resolve this problem?

Timezone (php parameter) on both server (Master/Slave) is the same also date is the same.

I have the same problem with 1.8.3. The data shows right above the graphs in the scenario, and the page refreshes periodically, but the graphs do not graph the data. They simply show [no data] below the graphs.

Edit: I read on another post where deleting everything and starting over fixed his problem, so I tried it. It's working so far.
