Hello I have an APC UPS connected via USB to a Synology NAS. I use PRTG to monitor several SNMP oid and it works ok. im using synology's mib which i already imported to prtg. i have two questions since Im interested in using prtg to monitor everytime the UPS transfers.
- im currently monitoring input voltage but logically, the scanning interval is too high compared to the speed of the voltage changes. how can i monitor when the ups transfers from mains to battery?
- I have OID 220.127.116.11.4.1.6518.104.22.168.1.0 which returns a string with the latest transfer reason. it usually shows "input voltage out of range". i already added this sensor to the prtg device page but im finding difficult to understand how to log a new ups message when it transfers from main voltage to battery.
