Recently, the company is working on a cactiez-based project. Cactiez has a function that generates an alarm when the host goes down, for example, when the memory exceeds the threshold (or hard disk, traffic, etc, an alarm is triggered when the memory exceeds the threshold. The problem is that we do not know how to extract the data collected by SNMP from The RRD file and compare it with the threshold. Does anyone know? Thank you first.
