Help with adding traffic from IPTV snmp agent

Hello, so I have installed software for monitoring multicast streams. It is running on linux machine (ubuntu 18) and its standalone agent with different port for snmp. I can add that agent to librenms install, i can make sensors for state also, but what i want is to get traffic and CC errors data to librenms install for every multicast stream. There will be a lot of streams. I can add cc errors graphs throught custom oid, from github pull request. i can add traffic, but that traffic is in bytes and i want to be graphed in bits. Is there somebody who can help me with this. That OID is COUNTER.
