Cacti Network Grapher Virtual Appliance

cactiWow, it has been a long time since I have posted! It has been a really long time since I posted my MRTG Virtual Appliance. Today I hope to make up for some of that with this post of my Cacti RRDTool based Virtual Appliance. This virtual appliance is based on CentOS 67 and is designed to be lightweight, and stable. It has only a minimum of tools installed to make Cacti work.

The OS is set to DHCP, and Cacti is installed.

The username at the console, and passwords set for everything should be ‘cacti’ this will include root and mysql. **With the exception of the Cacti admin user, which has the password “Cactipw1!” (no quotes)

Cacti is all configured up and includes some plugins, which are not installed by default. It also has some additional host templates for Palo Alto firewalls, Cisco ASA Firewalls, F5 BIG-IP load balancers, and a few other things I have found useful over the years. [UPDATE] the new Cacti 1.x does not yet have all the old templates in place.

There is not a ton of documentation, as I simply have not had time. I have put together a minimal troubleshooting section below. If you are already familiar with Cacti it should be a breeze.  If there are any questions, please leave a comment, and I can assist and update as needed.

TROUBLESHOOTING

Network interface not showing up after you import the template?
Couple things to check;
Does /etc/udev/rules.d/70-persistent-net.rules exist?
If so, lets move it out of the way (this command moves it to the users home directory);
sudo mv /etc/udev/rules.d/70-persistent-net.rules ~/
Now lets check the interface configuration;
cd /etc/sysconfig/
The “network” file here will be where you control your systems hostname, its default hostname is “cacti-template”, change it freely.  If you don’t mind, you can ignore this file.
cd network-scripts/
In this directory you will have your network interface configuration files;
Loopback = ifcfg-lo
Primary Interface = ifcfg-eth0
If your network interface is not showing up, you may have a MAC address issue.  You will need to update the ifcfg-eth0 configuration with your actual MAC address.  The MAC address field in the ifcfg-eth0 configuration file is;
HWADDR
Get the mac address of the physical network adapter from the virtual machine’s settings, and simply replace the existing entry in ifcfg-eth0 with that MAC address.
Once the /etc/udev/rules.d/70-persistent-net.rules file is moved out of the way, and the ifcfg-eth0 configuration is updated, reboot the system and you should have networking.

  1. Okay, so the final solution is issue following command.

    xfs_growfs /dev/mapper/centos_cactitemplate-root

    Looks like XFS is the default filesystem in CentOS.

    Now df -h shows new size.

  2. Hi Kevin,

    I thought I was able to extend the existing logical partition with details as below, to about 40GB. Any one with little experience with Linux, has to be ultra careful to not lose any data. So they should better snapshot the VM and / or take DB backup etc.., if they will try to follow my process.

    1. Shut down the Cacti VM.
    2. Under edit settings of VM, I then changed hard drive size from 8GB to 40GB , selecting hard disk, change provisioned size to 40GB thick. I also increased CPU to 2 vCPUs and RAM to 2GB.
    3. Power on the Cacti VM and SSH into it using root.
    4. lsblk
    5. vgdisplay to check existing filesystem size allocation.
    6. fdisk /dev/sda
    Press p to print the existing partition table details and note it,
    Press d and then 2 to delete existing second partition.
    Press n and then p and then 2 to create new second partition. Enter to accept default for first sector and then again Enter to accept default for last sector.
    Press t then 2 then 8e to change system partition 2 , Linux LVM, and then w to write / save.
    7. Now physical drive has been expanded.
    8. to add this extra available size to the logical drive,
    lvextend -L39G /dev/mapper/centos_cactitemplate-root
    9. vgdisplay and lvdisplay to verify. This shows new expanded partition size, but somehow df -h still showed me the same.

    I am not sure if I simply add the second drive to the OS, it can be used by Cacti.

    Thanks

  3. In my experience it is easier to simply add another virtual disk rather than expanding the original. I am not an expert at that part so I would suggest a search for adding disks in centos7

  4. Hi Kevin, when I installed the OVA, it created a 8GB disk. is there a way to increase disk space for OVA installed VMs? I am not using it in commercial setup, just installed to learn it, and I tried to increase disk space under VM settings, it takes it there, but doing a df -H at Cacti shell still shows the same 7.2G disk etc..

    Thanks much,

  5. Hi Alvaro Arbuet ,

    With virtual machines, on CentOS7, you will not see ifcfg-eth0 file. Instead you will see ifcfg-esp0s3 and ifcfg-lo0. And if you will do ifconfig, you may not find esp0s3, instead there may be ens160 etc. To do static IP, you will create a file under /etc/sysconfig/network-scripts named ifcfg-ens160. If you will do vi ifcfg-ens160 from within network-scripts directory, it will auto create this file, which will be blank. Then press i and you will see at the bottom –insert–, so now you can type following (the Hwaddr is the mac address as you will see under cacti VM settings for the NIC, this is virtual mac assigned by ESXi or KVM etc..
    TYPE=Ethernet
    HWADDR=00:0c:29:ec:12:34
    BOOTPROTO=”static”
    IPADDR=172.16.30.200
    PREFIX=24
    DNS1=8.8.8.8
    GATEWAY=172.16.30.1
    NM_CONTROLLED=no
    ONBOOT=yes

    Now press Esc and then press :wq! to save and exist.

    Technically now you are supposed to restart the service via “system restart network” but I get error. So I just did a reboot at the command line and when it restarts, you will be pinging the new static IP.

    Hope this helps,

  6. hi kevin, how can I change dhcp to static ip? I try change config on ifcfg-ens*** but dont do any
