Alerting via SNMP TRAP

Install Prerequisites (skip that in case of Virtual Appliance)

AIX
Download Net-SNMP packages and install them.
Do not use the latest packages for AIX, it does not work, use net-snmp-5.6.2.1-1! It will not work with AIX standard OS cmd /usr/sbin/snmptrap!
```
# umask 0022
# rpm -Uvh net-snmp-5.6.2.1-1 net-snmp-utils-5.6.2.1-1 net-snmp-perl-5.6.2.1-1
```

Linux
Follow this to get installed SNMP support in the tool on RHEL8 and CentOS8.

# umask 0022
# yum install net-snmp
# yum install net-snmp-utils
# yum install net-snmp-perl

Linux Debian/Ubuntu
```
% umask 0022
% apt-get install snmp libsnmp-perl snmp-mibs-downloader
```
Assure that this line is commented out in /etc/snmp/snmp.conf
```
#mibs :
```
If apt-get does not find snmp-mibs-downloader package then enable contrib and non-free repositories.
