Max graph size

Post by syn »

using cacti 0.8.8f
I've tried RRDtool 1.4.7 and 1.5.5
If a graph is over 80 lines of data, RRD tool dies.
example debug output:

Code: Select all

It appears the indexing convention conflicts at "cf,cf"

Any ideas?

My speculation was correct.
Changing

Code: Select all

$lookup_table = array("a","b","d","c","e","f","g","h","i","j")
to

Code: Select all

$lookup_table = array("a","b","d","e","f","g","h","i","j","k")

Can you give the file, line and function in which you changed that? It may be an issue that does not exist in the latest Cacti but I want to be sure :)

The same fix can be applied to the latest version too. I'll create a push request and apply your fix.
