MRTG CPU / Memória

Pessoal, instalei o pacote do NET-SNMP e o MRTG num slackware 10, gostaria de monitorar a Memória TOtal / LIvre e o percentual de uso do processador, já tenho isso funcinando com scripts, mas agora tenho que fazer por snmp, alguem tem algum .cfg do mrtg ai que esteja funcinando?

Valeu t+

Ps: Tem q ser por snmp, pois vou monitorar várias máquinas.

Valeu

Tente isto:

Código :

---

snmpwalk -v sua_versão_snmp -c sua_community aaa.bbb.ccc.ddd .1.3.6.1.4.1.2021

---

Exemplo:

Código :

---

snmpawlk -v 2c -c public 192.168.1.1 .1.3.6.1.4.1.2021 > log_snmp

---

Veja o log e vc vai descobrir as mibs que quer usar:

Código :

---

vi log_snmp

---

Irá aparecer algo deste tipo (vou colocar apenas uma parte, pois cria uma arquivo grande):

Valeu, qualquer dúvida, é só postar ai ok. :mrgreen:

Ola Pessoal


Peguei o exemplo do grafico do cpu, so que nao esta funcionando
quando eu dou o comando mrtg cpu.conf da a seguinte msg de erro:

#mrtg cpu.conf
#Unknown SNMP var ssCpuIdle.0
at /usr/bin/mrtg line 1491
Unknown SNMP var ssCpuIdle.0
at /usr/bin/mrtg line 1491
WARNING: Expected a number but got '23:58:04'

Alguem pode me ajudar ?
