ERROR: Legend set but no color: Outbound

Post by iperman »

Hi,

I have just upgrade cacti to 0.8.6e, and i have this little problem, when i activate debug mode on graph :

RRDTool Says:
ERROR: Legend set but no color: Outbound

The only type of graph which is impacted is 95th perctentile graph.

Can you help me ?
Thanks

That's Odd. Please send Graph Syntax (logging to DEBUG, and view the graph via Graph Management, then view logfile, it will show syntax). Then post that and the RRD files. Thanks!!!

For those wondering, I'm still here, but lost in the shadows. Yearning for less bugs. Who want's a Cacti 1.3/2.0? Streams anyone?

I'm also having the same problem. I think this problem may be due to changes in rrdtool from 1.0.x to 1.2.x. This error seems to happen when using 1.2.x and your graph template has a data source without an assigned color.

Why would a data source not have an assigned color? When using it to compute a secondary value and graph it instead.

rrdtool requires the data source to exist in the graph before it is used in a computation or a gprint. Sometimes you aren't interested in graphing the data source itself but the computed value instead. In 1.0.x there was a workaround that allowed you to add the data source, set it to zero, and leave the color set to none. This made the data source hide in the background w/o appearing in the graph or legend. This workaround doesn't seem to work anymore in 1.2.x.

Apache Stats seems to be a good example. There is a graph templated titled "Unix - Apache Statistics - Bytes / Request" where the hits are merged with the kBytes to give a computed B/hit data source. In my configuration the graphs this template generates are broken and gives the error: "ERROR: Legend set but no color: kBytes\n". If I edit the graph template and set the hits and kBytes color to anything other than None the graph is generated but the legend now has both hits and kBytes listed (undesireable outcome).

Any ideas?

My environment in case it's necessary...
Cacti: 0.8.6f
rrdtool: 1.2.11
rrdtool 1.2.x features enabled?: yes
rrdtool 1.2.x fontpath set?: yes
Poller: poller.php
OS: SuSE Linux 9.2 (x86-64)

Same
ERROR: Legend set but no color: read io

syntax like
LINE1:c:"read io"
works fine with rrdtool 1.0.x
but with
rrdtool 1.2.x
produce this error

correct with 1.2.x this syntax: LINE1:c#FFFFFF:"read io"


exist any posibility include to graph datasource with "no color" to use it in gprint?

If you are going to use 1.2, you need to alter you templates/graphs to work.
