This is the output I get in nagios.log:
[1181921420] Warning: Service performance data command 'echo
'server01\tMemuse\tMemory usage: total:4485.60 Mb - used: 1452.13 Mb (32%) -

5667' for service 'Memuse' on host 'server01' timed out after 5 seconds
And this is what ngraph./log shows:

found...
The first part of check_ntmem.ncfg looks like this (there is more but it is
pretty long):
define ngraph {
graph_legend Memory Used
graph_perf_regex Memory usage=([0-9]+)Mb
graph_value Memory usage
hide yes
rrd_color 00a000
rrd_plottype AREA
service_name Memuse
}

I will definitely try that, thanks.

Correct that is right on the spot.

I appreciate the help you are giving, and sharing your experience, and
apologies for misunderstanding.
Thanks,
