The WAN Utilisation Distribution Report uses 'mode=>MAX' to ensure it is using the most accurate summarized data available for the task at hand.
NMIS currently doesn't export data using 'mode=>MAX', so a proposed replacement for '/path/to/nmis/cgi-bin/node.pl', named 'node_max.pl' can be made available to replace or run alongside 'node.pl'.
In this case we have chosen to run 'node_max.pl' alongside 'node.pl' which requires an extra steps to get NMIS to provide the desired data.
We must first place 'node_max.pl' at '/path/to/nmis/cgi-bin/node_max.pl' then set the required ownership and permissions:
sudo chmod 0770 /path/to/nmis/cgi-bin/node_max.pl sudo chown nmis:nmis /path/to/nmis/cgi-bin/node_max.pl
Open NMIS, login and choose the desired node we wish to work with - in the example image below we have chosen BANORTE_CAJ_N40051_NIHON_PLAST_II_RT01 highlighted in blue:
NMIS will then open a form for that desired node - to get NMIS node.pl to open click on one of the graph images - for example the graph highlighted in blue on this image:
