I just did a fresh install of the newest observium (0.13.7.4200). Everything is working well except for my nexus 5k devices show a draw error for memory. Memory stats for the switches was working in previous observium releases. Here is the output from the poller below. I can get the memory from snmp via command line, I assume some mibs are messed up?
