BW Graphs upper limit is not correct

[theomakaros]

The issue is that a bw graph created in the beginning with upper limit 100 in the templates' scaling option but the auto scale option were enabled with the sub-option " Use --alt-autoscale-max (accepting a lower limit)" enabled also.
This upper limit value is not enough and changed to 1000.
The issue is that the consumed bw is 300 or 400Mbps , which is verified from the firewall.
The graph has a peak value of 110 M, consequently i do not have a valid monitoring history.
The graph operates correctly only when i uses the real time choice.
Attached can be found the corresponding pngs.

Does any one faces the same issue ?

Cacti version : 1.2.24

This is a classic beginner's issue. You really should be graphing with the 64-bit counters and then ensuring that the max value in the rrdfile is correct. Oftentimes if the SNMP agent does not return the correct ifHighSpeed then cacti will set the max value in correctly in the rrdfile. I don't think that's your problem here though I think it's that you're doing 32-bit counters versus 64-bit.

Hello TheWitness thank a lot for the help.
You are correct. I have read this in a former post also and i created an 64-bit Bandwidth graph but i kept facing the same issue. After your reply i observed that the new 64-bit graph were using the same rrd file.
When i deleted the rrd file and created a new one 64-bit graph , cacti created a new rrd file and the issue resolved. png for reference

For new user like me that will have the same problem :

You can locate which rrd file is used from the graph if you turn on the debug mode : Link for reference

The path of the rrd file is : /var/www/html/cacti/rra
