Some Graphs Break After Upgrade to Cacti 0.8.7a

TheWitness

All,

If you obtain some broken graphs after upgrading to Cacti 0.8.7a, please use the attached lib/functions.php to resolve the issue.

"I" appologize for this inconvenience.

Regards,

TheWitness

Tried this. Although it fixes my originally broken graph, it now breaks the existing HOST MIB graphs (disk stats etc) which were working before ???

What exactly is broken with it?

Post the graph debug for it and an rrdtool info on that file. The underlaying issues is older versions of cacti didn't properly create all CF's for average, max, min, and last.

BSOD2600 - My mistake. I have a custom CDEF which shows the amount of free space on the graphs (HOST MIB). This wasn't working yesterday before Larry's fix, and I was able to determine that it was no longer a,b,- but actually a,c,-

Larry's fix reverted the graphs back to their default behaviour, so the CDEF no longer worked, and effectively busted the graph. I have changed my CDEF back to a,b,- which seems to have resolved the problem

Thanks

Actually, since applying the new functions.php, I have come across an error (possibly associated with PIA):

Notice: Undefined index: monitor.php: in C:\wamp\www\Cacti\lib\functions.php on line 1632

This error varies depending on which plugin I am using (always the same line number though). The previous version of this file didn't exhibit this issue, so I am hazarding a guess that something is missing which the PIA requires ?

Thanks

Ok, found it. After a bit of investigation, it actually is PIA related - the following is missing on line 1628:

$nav = do_hook_function('draw_navigation_text', $nav);

To make life a little easier, here's a revised version of functions.php, which needs to be copied to cacti\lib

Anytime I click a plugin I got this notice:

Notice: Undefined index: weathermap-cacti-plugin.php: in /work/cacti-0.8.7a/lib/functions.php on line 1632

This happens with lib/functions.php attached here in this thread

Strange, as this works for me (this file is the one with the changes). Which PIA are you using ?

Thank you

After I upgraded to 0.8.7a, the graph were stop graphing. And I used the official patch to fix that problem, it still doesn't work. Is there I can provide to help trouble shooting ? Or there's anything I missed ?

Thank you.

This fixes actual graphing, not collection of data which you have. Follow http://docs.cacti.net/node/283

My problem sloved, thank you.
The reason my cacti stoped graph was the file privilege problem.

The functions.php that TheWitness uploaded fixes the problem for me, however I now see a warning when I go to graph_view.php (without any parameters)

Warning: Cannot modify header information - headers already sent by (output started at /usr/share/cacti/site/lib/functions.php:1941) in /usr/share/cacti/site/include/top_graph_header.php on line 54

I'm using the debian package and my guess is that the maintainers changed some things. The file that mcutting uploaded broke pretty much everything

Double check file permissions on that new file / cacti files.

nope, they're exact the same. I'll do some diff's and see if I can find a fix that way.
