Nesse artigo vou falar como adicionar host , remover , mudar o nome e adicionando usuário na linha de comando do observium .

Vamos verificar a resposta de snmp, caso não obtenha resposta você vai precisar configurar para os passos posteriores.

Caso obtenha sucesso vamos aos passos seguintes.
Adicionando um host, lembrando que o nome do servidor adicionado deve está disponível no servidor de dns que ele fará a consulta.
A sintaxe do comando .
root@cacti:~#php /opt/observium/add_device.php
Observium CE 0.16.9.8118
Add Device(s)
USAGE:
add_device.php <hostname> [community] [v1|v2c] [port] [udp|udp6|tcp|tcp6]
add_device.php <hostname> [any|nanp|anp|ap] [v3] [user] [password] [enckey] [md5|sha] [aes|des] [port] [udp|udp6|tcp|tcp6]
add_device.php <filename>
EXAMPLE:
SNMPv1/2c: add_device.php <hostname> [community] [v1|v2c] [port] [udp|udp6|tcp|tcp6]
SNMPv3 : Defaults : add_device.php <hostname> any v3 [user] [port] [udp|udp6|tcp|tcp6]
No Auth, No Priv : add_device.php <hostname> nanp v3 [user] [port] [udp|udp6|tcp|tcp6]
Auth, No Priv : add_device.php <hostname> anp v3 <user> <password> [md5|sha] [port] [udp|udp6|tcp|tcp6]
Auth, Priv : add_device.php <hostname> ap v3 <user> <password> <enckey> [md5|sha] [aes|des] [port] [udp|udp6|tcp|tcp6]
FILE : add_device.php <filename>
ADD FROM FILE:
To add multiple devices, create a file in which each line contains one device with or without options.
Format for device options, the same as specified in USAGE.
OPTIONS:
-p Skip icmp echo checks, device added only by SNMP checks
DEBUGGING OPTIONS:
-d Enable debugging output.
-dd More verbose debugging output.
-t Do not add device(s), only test auth options.

Renomeando o servidor .
Os dois endereços de dns do host devem existir na tabela de dns do servidor de dns consultado para essa operação.
