Hey, i just want to practice about using snmp service on icinga. Maybe i want to use check_snmp command. But i dont know how to add the command into icingaweb dashboard. I had read some article that have to download the script check_snmp on Icinga Exchange. so i downloaded it, but i dont know how to install it.
