Real time graph works but other graphs does not work

Hello community,

I was wondering if some one can help me or point me to the right direction. I’m new to librenms and I took over this server from some else that left my company. I having issue of some device having graph data but other device ( cisco router, switch , servers) will not pull any data. I can do snmp walk from my librenms server and real time graph works. The validate on the gui and server said there is nothing wrong. Does anyone has some idea where should go next?
