I just upgraded from 0.8.6j to 0.8.7b and a few of my graphs no longer function the same.
Whenever I add a data source to a graph to get a total, the Maximum on the Legend only displays the value for the data source the Legend was created under. The Current and Average value seem to be correct.
The dip in the new graph is when I moved the RRDs over but similar graphs with no dips are behaving exactly the same. I've tried re-creating a graph a similar way and it no longer functions the same. Basically I just want to take mutiple data sources and represent them as 1 single data source on a graph. I know about the aggregate plugin but I'm not sure why this is no longer working.
Cacti Version - 0.8.7b Plugin Architecture - 2.0 Poller Type - CMD.php Server Info - Linux 2.6.18-53.el5 Web Server - Apache/2.2.3 (Red Hat) PHP - 5.1.6 PHP Extensions - libxml, xml, wddx, tokenizer, sysvshm, sysvsem, sysvmsg, standard, SimpleXML, sockets, SPL, shmop, session, Reflection, pspell, posix, mime_magic, iconv, hash, gmp, gettext, ftp, exif, date, curl, ctype, calendar, bz2, zlib, pcre, openssl, apache2handler, gd, mysql, mysqli, PDO, pdo_mysql, pdo_sqlite MySQL - 5.0.22 RRDTool - 1.2.26 SNMP - 5.3.1 Plugins
It appears the NEW version of the command has 3 new variable with MAX in them. I'm seeing similar behavior in other graphs that are broken in this fashion.

Just a guess, try switching rrdtool to 1.2.26 or the 1.3 beta. I recently solved a problem with large graphs breaking after 0.8.7b. Turns out the older rrdtool 1.2.15 I was using had issues and upgrading to 1.2.26.
Otherwise, going to need a dev to figure out why the new graph format doesn't work. Could post your question (with old/new graph outputs) on the rrdtool mailing list too.

Hmm, it seems the old box was running RRDtool 1.2.23 and the new box RRDtool 1.2.26. Perhaps something screwed up between those 2 releases.
I have tried to seek help from the RRD community as well as downgraded my RRDTool back to what was working on the original install (1.2.23) and the behavior still occurs.
Right now, I'm leaning towards it being a bug in this version of Cacti.
I'm still looking for a resolution to this post. I have no clue why the MAX values on my additive AREA graphs are incorrect. Please advise on how I'm supposed to fix this issue.
The graph DEBUG shows, that you have DEFs for data source with cf=AVERAGE and those with cf=MAX. When using "SIMILAR_DATA_SOURCES_NODUPS" or the like, AVERAGE and MAX will be considered not to be SIMILAR.

Thats just the thing, nothing changed in the config from 0.86j to 0.87b. I'm aware that the debug now shows MAX where my old install did not. The question is, how do I get rid of them? The graphs are built exactly the same as they were in 0.86j and they worked fine. You can see from the screenshot that they are all CF=AVERAGE except for the initial LEGEND.
It would be easier if the linked data was posted inline.
Let's take e.g.
LINE3:cdefbd#00FF00FF:"Outbound" \
It refers to cf=MAX, outbound. Since there is only a single MAX outbound DEF, the sum over all MAX outbound's equals this single one. If you'd like to see the sum of AVERAGE outbound's, simply visit that graph item and change cf from MAX to AVERAGE

Well I changed the MAX to AVG but it had no effect. The Maxiumum is still incorrect in the graphs and the debug looks the same. There is a hidden MAX somewhere in here that gets created using 0.8.7b using this graph type.
