48 Hour Graphs not working

[nelsonab]

It seems that every time I attempt to get a 48 hour graph I get empty graphs. Currently we're running 1.1.

This happens with both individual and screen views. To reproduce I first select a 24 hour graph, then increase it by 24 hours.

Is anyone else seeing this same behavior?

[peter_field]

Yes, I can reproduce this. Running 1.1.2.

Display a graph over 24 hours, add 24 hours, and all I get is a little sample of data on the left of the graph, and I cant move left or right.

If I change to week, month, or year I have data.

I can also change to week view and decrease by 24 hours at a time, which works right down to 3 days, but when it goes to 2 days, same problem.

Also interesting is when I move left or right in 2 day view, the working time moves, but the small sample of data on the left of the graph doesn't move or change.

Try to open your php.ini and double memory settings.

I have memory_limit = 16M and it works, it didnt work with 8M.

You probably will have to reload your apache after that.

[peter_field]

I set the memory_limit to 16M and restarted and still it doesn't work. It does works for 1 day, and for 3 days, but not 2 days. Seems weird.

I have the same problem here, no 48h graph
I tried to set memory_limit to 16M, same behavior
but in my phpinfo, i found in the configure command '--disable-memory-limit'
so i'm not sure this will fix anything for me

[AlfieRB]

I have the exact same problem using version 1.1.2. My memory limit is also set to 16M, and it seems to make no difference. And stops working at 2d, but seems to start working again between 2.5 and 3 days. Anyone have any insight?

[muthukrishan]

Iam using version 1.1.2 and the graphs are not showing for 1Hr average, but it is able to show for 2 Hrs, etc.

I'm having the same problem. Have a look at the my last post in my thread to see if you've got a similar setup:

[cadbury]

after some tests, it start screwing at 25h, and it go well after 3d2h for me

[peter_field]

Heres a sample of one of my configs:

I know this sounds stupid but make sure your using the correct libs/frontend with your version of zabbix.

I am still having this problem with 1.1.2 so i ended up downgrading back to 1.1.1 and that worked for the time being.

New versions of zabbix are able to be added and changed quite easily with the setup i've got here. Heres an idea (we're able to select between 1.1, 1.1.1 and 1.1.2):

All we need to do is do a service zabbix_server stop
then change the version variable to 1.1.2 and save the file.
and do a service zabbix_server start and hey presto!

Here's the /etc/rc.d/init.d/zabbix_server file:

all other zabbix related files are stored in /opt/zabbix

there is a new directory structure though:

/opt
/opt/zabbix
/opt/zabbix/bin
/opt/zabbix/libs
/opt/zabbix/libs/1.1
/opt/zabbix/libs/1.1.1
/opt/zabbix/libs/1.1.2
/opt/zabbix/www
/opt/zabbix/www/1.1
/opt/zabbix/www/1.1.1
/opt/zabbix/www/1.1.2

the above file creates soft links to the correct directory. and uses the correct zabbix executable in the bin folder. we have 3 executables there which is zabbix_server-1.1 zabbix_server-1.1.1 zabbix_server-1.1.2

so with a new release it's a whole lot easier to manage :)

I found a temporary fix. I modified the graph.inc.php under selectData function from if($this->period <= 24*3600) to if($this->period <= 71*3600). Could it be that the trends database is empty between 1d1h and 2d13h why the original settings in graph.inc.php do not work.
from http://www.zabbix.com/forum/showthread.php?t=4248
does anybody else tested this?

[alj]

I set the memory_limit to 16M and restarted and still it doesn't work. It does works for 1 day, and for 3 days, but not 2 days. Seems weird.

Actually i noticed - if you select "Period" to +*h (any number of hours) then press "+24h" it breaks graph instantly no matter how many hours was set originally.

So it is broken for me too.
Zabbix 1.1.2, debian-testing standard package.

after changing graph.inc.php, it work well (for me with 73*3600, i had no graph for 3d and 3d1h else)

[richlv]

zabbix 1.1.3, the problem still seems to be there.
graphs break in the interval 25h - 2d8h.
fix suggested indeed works (i had to set it to 56*3600), but, of course, periods after 2d generate quite slowly.

as already suggested, it seems periods between 25h - 2d8h. don't have trend data stored, but frontend believes they have.
the fix probably either has to increase this value in the fronted, as done here, or (probably the correct solution) fix trend data not getting stored.

it would be nice to receive an upstream fix, as it is pretty trivial for the fronted and probably only slightly more difficult for trend storing :)

edit: oh well, here's the simplest patch ever, for 1.1.3 (it seems missing periods change over versions...)
as usual, -p 1 from the frontend index directory itself.

Hi,

i get this problem with oracle for all graph.
My fix is:
in include/classes/graph.inc.php, and line 926, 933 and 943, i replace the 'i' with the commented instruction.
But i don't understand why the alias 'i' is not valid.

see attached file.

Thanks
