// What is Cacti? Cacti is a network system that inputs system-generated quantifiable data and presents the data in spiffy graphs. Net-Admin In the Net-Admin world, it gives you time-critical and time-historical data to help you make important decisions. Typical data inputs are things like: switch-port-utilization, environmental information (temperature, humidity, etc.), system criticals: storage space, CPU time, etc. Security-Admin Combined with SIEM and other system data sources, Cacti can be used to generate security baseline and normalization patterns. It’s also a quick sanity check on the network.

Installing Ubuntu 16.04 We are installing from the ISO ubuntu-16.

Canon Mp970 Printer Error 5200. You will be prompted to create a MySQL root account password. Create the password (don’t leave it blank), keep it handy (you’ll need it soon when working with mysql and mysqladmin) and continue on. After installation, login. Note all those updates we need to do!

Update Base System sudo -s apt-get update apt-get upgrade reboot -h now Configure Network After the updates are completed, setup your network stack. Then reboot.: sudo -s nano /etc/network/interfaces Notes on nano: CTRL+O to write changes, CTRL+X to close Update your network settings and reboot once more. Reboot -h now Note on sudo & root Most of the work done from here on out is done at root since most this work is done within /opt/ and installing bits. Sudo-s Install Pre-Reqs After the reboot login once again.

Ickler // we installed and got Cacti up and running. Now, we’re going to add our first switch into Cacti’s services. Switch: This is an HP-Procurve line switch. Because we’re going to configure the switch from the command line the general configuration will apply to multiple models within the ProCurve line. The Web-Interface could also be used. The general configuration necessary is to enable SNMP services on the switch.

The SNMP services will be listening on the switch’s management interface/IP. I make the assumption that you already have configured the switch to have an IP address on your (management) network. Additionally, I make the assumption you can access the switch’s CLI via SSH, Telnet, or Serial. SNMP Strings & SNMPv1 Caution SNMPv1 allows a simple SNMP query to the SNMP service. These queries are not encrypted, but also are not complicated to setup. We’ll cover V2 and V3 later. Your SNMP *read* string shouldn’t be the default “read” – come up with something more clever.

This string is used to authenticate the SNMP agent (cacti) to the SNMP service on the switch to query information. In this example, we are using “SomeReadString” Configure SNMP on Switch: SSH or telnet or serial into the HP Procurve switch Enable Config Snmp-server community “SomeReadString” Snmp-server contact “ TheAdmin@YourDomain.com ” End Write Memory Add the Device (switch) to Cacti: Login to Cacti and click on “Devices” Click on “Add” Enter Description: Name the switch in Cacti Enter Hostname: The IP of the switch Device Template Net-SNMP Device SNMP Version: 1 SNMP Community: **Your “Read” string from above “SomeReadString” Press Create at the bottom. Create Graphs in Cacti for the Device After pressing create, if everything is configured properly, information for the switch will imediately populate, followed by additional options. Click on Create Graphs for this Device. Scroll down to the “Data Query [SNMP – Interface Statistics]” Section. Select each interface that you would like to graph, or select all of the graphs. Change the graph type to “In/Out bytes with Total Bandwidth” Then click on “Create” at the bottom.
