# Php/var/www/html/cacti/poller. php>/dev/null 2> & 1
(8) Use Cacti to monitor Linux Hosts
# Install net-snmp on the monitored linux host
Yum install net-snmp
Vi/etc/snmp/snmpd. conf
# Modify the following parts
# Set the default value in the following line
Com2secnotConfigUser default public
# Change to 10.0.0.52 (cacti) server address)
Com2secnotConfigUser 10.0.0.52 public
# Set systemview in the following line
Access notConfigGroup "" any noauth exact systemview none
# Change to all

# Remove the comment "#" in the following line
# View all supported ded. 1 80
