Nagiosgrapher graph-configuration

[Gerd Mueller]

Hi,

add this block to your definition.

define ngraph{
         service_name            Memory RAM
         graph_perf_regex        ;(\d+)$
         graph_value             ram_100p
         graph_units             MB
         graph_legend            total RAM 
         rrd_plottype            LINE1
         rrd_color               00ff00
}

This should do what you want. But nagiosgrapher cannot extend the existing rrd files so you have to remove the old rrd files. 

Cheers,

Gerd
