Prometheus is mostly for regularly collected statistics and state. what would you recommend for statistics that are only collected when something happens? stats that aren't available on schedule. as an example, take UPS state changes to battery mode or overvoltage mode. Prometheus can't collect them when they are short lived.
Depends
To me this is where SNMP traps shine, its quite specifically its purpose. Which means alloy, logstash, snmptrapd + promtail, logstashetc. Which fits best depends on what youre doing, I personally lean simple first. Do you want traps by themselves? Remote logs? Do you have a device thats already handling relays that can be triggered? How does the UPS connect? If its serial or USB over to a dedicated machine, that machine should log and send upstream.
