This question is probably ~20 years old and we've ended up with things like the USB Table Traffic Light that you can buy now for arround 70,-€. [...]

Unfortunately, manufactures for RAID controllers create their own tooling, which makes it difficult to monitor them using generic monitoring protocols. If you are familiar with [...]
Network Attached Storage devices are very popular in small or medium offices or at home to store and share data. Synology is one of the manufactures who build their devices with SNMP support to provide monitoring and managment capabilities. This makes it very easy to let OpenNMS keep an eye on your NAS and it can tell [...]
