I would like to monitor the usage of my DS1812+ using PRTG. I have enabled the SNMP both in the synology control panel and in the prtg machine (e.g. I can perform uptime monitoring using SNMP). However, the error "End of MIB view (SNMP error #224)" always occurs when I try to set up SNMP Synology Disk Physically or Logically. Could you please help me on this matter?
