SNMP read issue

Hi Guys,

I’ve suddenly observed that in some of my Arista devices, the librenms doesn’t show port traffic , and doesn’t read mac addresses of the switch, all of the rest it succeeds to pool,such as CPU,temperature, please advise how to troubleshoot this kind of issues? it happens in 20 switches, I know for sure it’s not a MIB issue on the switch as I’ve the same switches in other DC’s and there it shows the traffic

Found the issue, there was no storage space on the server
