How To Install amavis-snmp on CentOS 8
Introduction
In this tutorial we learn how to install amavis-snmp on CentOS 8.
What is amavis-snmp
This package contains the program amavisd-snmp-subagent, which can be used as a SNMP AgentX, exporting amavisd statistical counters database (snmp.db) as well as a child process status database (nanny.db) to a SNMP daemon supporting the AgentX protocol (RFC 2741), such as NET-SNMP. It is similar to combined existing utility programs amavisd-agent and amavisd-nanny, but instead of writing results as text to stdout, it exports data to a SNMP server running on a host (same or remote), making them available to SNMP clients (such a Cacti or mrtg) for monitoring or alerting purposes.
