How can i delete a specific graph data?

For example: I want to delete Series 2;

Just to clarify, are you looks to remove a data source from the rrd, or remove the whole rrd itself?

I believe you will need to modify the plugin to return only the "Total" perfdata, remove the RRD and XML file for this check and wait for them to be recreated. You will lose all of the historical data. I am not sure if there is an easier/better way of doing this.

I would like to remove data source from the rrd, but if its not possible, i'll remove the whole rrd.

How could i remove the RRD and XML file?

You need to first remove stop the datasource from returning in the check, because if it is still returning, it will get added back to the edited/new rrd.
Once you have done that, you could attempt to remove the datasource with a tool like:

Or you can just remove the whole rrd by deleting the file: The rrd will be recreated and the xml overwritten on the next check.

I got it.

I ran the command:

find /usr/local/nagios/share/perfdata -iname Qtde_de_Processos* -exec rm -f {} \;

Thx.
