Interface bps NAN

Hi!
I want to graph the ports of my Aruba, Firewall and Dlink switches to check their interface usage/bandwidth. I have start with DLink switch but the bps graph is not showing any data.
I am using snmpv2. Its an 1G graph.

./validate.php

Component Version
LibreNMS 1.63-27-ge7b371e1c
DB Schema 2020_04_19_010532_eventlog_sensor_reference_cleanup (164)
PHP 7.2.30-1+ubuntu18.04.1+deb.sury.org+1
MySQL 10.1.44-MariaDB-0ubuntu0.18.04.1
RRDTool 1.7.0
SNMP NET-SNMP 5.7.3
====================================

[OK] Composer Version: 1.10.5
[OK] Dependencies up-to-date.
[OK] Database connection successful
[OK] Database schema correct

I did run tune as well for testing purpose but still the same.
Tuning port 1/16…
Tuning port 1/17…
Tuning port 1/18…
Tuning port 1/19…
Tuning port 1/20…
Tuning port 1/21…
Tuning port 1/22…
Tuning port 1/23…
Tuning port 1/24…
Tuning port 1/25…

How can fix this?
Thanks

I don’t under you asking about Aruba and then dlink switch?

Sorry I didnt get you. What I meant was that I want to graph my network devices interface utilization and they are from different vendor so I am just checking my Dlink switch with Librenms right now.
I looked again nad I can see but its not showing the max value.

If I do real time then I see this

why the graph is not showing that it did touches 800Mbps.
Thanks
