rrdtool-1.2.11-3 + cacti-0.8.6f-2 (Monitoring)

Tested on 08/Nov/2005 by SuSE 10.0

RRDTool (Round Robin Database Tool) is a tool to generate graph from any kind of data sources. This tool can replace MRTG.

This tool, perhaps, does not have a data gathering function. It needs some front-end tool to gather data such as, HotSaNIC, and Cacti.

Cacti can be configured on Web by PHP/MySQL.

Install SNMP

Make sure net-snmp is installed, configured, and running.

On Linux, net-snmp-5.2.1-10.i586.rpm is installed, and configuration would look like this (etc/snmp.conf).

#

            # First, map the community name "public" into a
            "security name"

            # sec.name source community

            com2sec public default public

            # Second, map the security name into a group name.

            # groupName securityModel securityName

            group public v1 public

            group public v2c public

            group public usmpublic

            # Third, create a view for us to let the group have rights to:

            # name incl/excl subtree mask(optional)

            view all included .1

            # Finally, grant the group read-only access to the systemview view.

            # group context sec.model  sec.level prefix read write notif

            access public "" any noauthexact all all all

            # System contact information

            #

            syslocation xxxxxxxx

            syscontact foo@host

On Windows 2000, XP, 2003, SNMP Service should be installed, and it would look like this,
On CISCO products, SNMP configuration would like like this,

gw(config)#snmp-server community public RO

Make sure, snmp is running and accessible. If necessary, open 161 tcp, udp ports on the target device.

# snmpwalk -v 1 192.168.1.100 -c public | less

          SNMPv2-MIB::sysDescr.0 = STRING: Hardware: x86 Family 6 Model 9

          MPATIBLE - Software: Windows 2000 Version 5.1 (Build 2600 Uniprocessor
          Free)

          SNMPv2-MIB::sysObjectID.0 = OID: SNMPv2-SMI::enterprises.311.1.1.3.1.1

          DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (80732) 0:1

          SNMPv2-MIB::sysContact.0 = STRING:

          SNMPv2-MIB::sysName.0 = STRING: TS-NEC

          SNMPv2-MIB::sysLocation.0 = STRING:

          SNMPv2-MIB::sysServices.0 = INTEGER: 76

          IF-MIB::ifNumber.0 = INTEGER: 4

          ....

Install Cacti

rrdtool must be installed in default. If not, install

# rpm -ihv rrdtool-1.2.11-3.i586.rpm
You need MySQL, apache, php...etc, and also running. Make sure you have a session module for the php.

# rpm -qa | grep php4-session
php4-session-4.4.0-6
Install cacti.

# rpm -ihv cacti-0.8.6f-2.noarch.rpm

Create database in mysql,

# cd /usr/share/cacti

          # mysqladmin -u root -p create cacti

          Enter password:

          # mysql -p cacti < cacti.sql

          Enter password:

Create a password and access permission to cactiuser.

# mysql -u root -p

          Enter password:

          Welcome to the MySQL monitor. Commands end with ; or \g.

          Your MySQL connection id is 87 to server version: 4.1.10a

          Type 'help;' or '\h' for help. Type '\c' to clear the buffer.

          mysql> GRANT ALL ON cacti.* TO cactiuser@localhost IDENTIFIED BY 'password';

          mysql> flush privileges;

          mysql> \q

          Bye

Edit /usr/share/cacti/include/config.php

...

          $database_type = "mysql";

          $database_default = "cacti";

          $database_hostname = "localhost";

          $database_username = "cactiuser";

          $database_password = "password";

          ...

You may give an access permission from your LAN. Edit /etc/apache2/conf.d/cacti.conf

Alias /cacti/ /usr/share/cacti/

          <Directory /usr/share/cacti/>

             Options None

             order deny,allow

             deny from all

             allow from 127.0.0.1 192.168.0.0/24
