Install and configure cacti

Is very important have a good tool to monitor our devices in a networking.

Cacti do this and very well. Cacti offers graphs using rrdtool to monitor the

load average, ping latency, disk space and other relevant information over

SNMP protocol. SNMP use the UDP port 161 for read and 162 UDP for

trap, and use a hierarchial database named MIB (Management

Information Base). MIB is a collection of objects and variables that stores

information about an agent.

In our scenario well monitor two servers the NMS server and well add

another one to our network.

1 # vi /etc/httpd/conf.d/cacti.config

1 # vi /etc/sysconfig/iptables

1 # service iptables restart



check all the tools are installed in our system before install cacti:

- Create graphs:

Management> Devices > device > Add



Create > new graphs

- SNMP Configuation (server client):

123

# yum nstall net-snmp net-snmp-utils# chkconfig --levels 235 snmpd on# vi /etc/snmp/snmpd.conf



check we can collect information about this server:

12

# service snmpd start# vi /etc/sysconfig/iptables

1 # service iptables restart

1 # snmpwalk -v 2c -c public 192.168.1.58



- Add host cacti:

Management > Devices > Add

Create > New Graphs

Management > Graph Trees > Default Tree > Add

- Section graphs:

Hello, Ivan!

Could you tell why wouldnt my Cacti be able to determine the

status of CENTOS machine? Did everything like you said, but still

getting Unknown value in the Status column (@Management-

>Devices) and the RTT stays 0 all the time.

Regards,

Alex

I think need to restart the httpd service before or after iptables

change. I also facing that problem. But after restarting the httpd,

it is ok.
