instead of the parse errors from 0.8.5

[fletch]

CF is a consolidation function.

I remembered I had chosen LAST for my graph template instead of the default Average.

Change the lasts to averages and resaved the template.
Deleted the old graphs, created new ones - golden

Hi,

Just stumbled across this through Google and I can confirm I was using a consolidation function of 'Last' in my graph; changed this to 'Average' and all working ok.

Many thanks!

There is a fix for cacti 0.8.7a in the announcement forum; you need an updated functions.php.

[jacobskp]

The updated functions.php did not get rid of this problem. I can still fix it by changing LAST to AVERAGE, but my graph doesn't look the way that I want it.

[otisbrown]

Have you confirmed that LAST is selected in the defined RRA?

[cinergi]

I suffer the same problem and the posted fix doesn't help. See my post here (which should answer otisbrown's question): http://forums.cacti.net/viewtopic.php?p=122040#122040

I ran into the same issue as the OP and this is what I found. If the RRA that is used by the data template that is used by the graph template does not have LAST selected as the consolidation function, when you modify your graph template to use LAST as the consolidation function your graph will not draw. After you make the change to the RRA I believe you will have to recreate the graphs, so the new RRA is generated.

Not REALLY REALLY sure, but quite:
I suppose that this drawback only hold, if you are using the LAST CF for a graph element as LINEx, AREA or STACK. It should not matter on a GPRINT.
To be honest, Up to now, personally I did not find any use of the LAST CF on a LINE. If anyone could please tell me, where this is required? Then I would like to add this as an example to the docs.cacti.net site.

Hi,

I had the same problem with some of my graphs when upgrading cacti from 0.8.6 to 0.8.7.a (I have also updated rrdtool to 1.2.26) - I was sure nothing was wrong with graph templates, and as I could not find any other solution I just deleted the problematic .rrd files ... and than the error dissapeard (and also the hystory from deleted .rrd files ... ).

[gandalf]

This one should be fixed by now. Will be published with next bugfix release.

what release is the fix incorporated into? i have just rolled out a new box running cacti 0.8.7b & rrdtool 1.2.23 with the updated functions.php and am hitting this error when attempting to use LAST in a graph. i have blown away the graph and associated files and started from scratch to no avail.

ideas?

[gandalf]

There are currently two different answers to the same problem. Some users have their problems fixed, some don't. I hope to work at least with one user to get it solved. Please post the whole failing rrdtool graph statement and rrdtool info for the rrd file used to help me debug it
