Step 1 - Download and Install

Megamon is packaged as a virtual appliance, which allows you to be up and running in a few minutes.

Request a licence

Before you can install Megamon, you need to request a licence. Megamon is currently available under three licence type editions: Micro, Professional, and Enterprise. The main differentiators between the editions are the number of nodes that are allowed in your networks, advanced escalation rules, and polling features. To decide which edition is right for your organisation, review the feature comparison table.

After you know which edition you want, request a licence through the above URL. Your licence will be sent to your email address.

Download the lastest stable release of Megamon.

 

Run the Megamon Virtual Appliance

After you have downloaded the Megamon Virtual Appliance (MVA), import it into your virtualisation environment, then start it up.

Important: If you use VirtualBox to run your virtualisation environment, you need to change the default Guest OS Type when you import the MVA. By default, VirtualBox selects RedHat (32 bit) for the Guest OS Type, but the MVA must be run as RedHat (64 bit). To change the Guest OS Type, complete the following steps:

  1. Select File --> Import Appliance.
  2. Select the MVA file from your system.
  3. Select Next.
  4. On the Appliance settings window, select RedHat (32 bit) in the Guest OS Type row, then select Linux --> RedHat (64 bit).
  5. Select Import

To run the Megamon installer, navigate to the IP address that the MVA displays on the first screen. You need the licence that was sent to your email to complete the installation process.

During the installation, Megamon creates a Demo site based on the network where it is being installed. When the installation is complete, Megamon displays the Demo site on the homepage. 

 

Change the password for the default user

The default username for Megamon is admin and the default password is admin. When you first use Megamon, you should change the default password. 

  1. On the homepage, select Settings --> Auth in the navigation menu.
  2. Log in using the default username and password.
  3. Select Change Password for the default admin user.
  4. Change the password to something you can easily remember.
  5. Select Save.

 

Configure a static IP address for your MVA (optional)

You can configure your MVA to always use the same IP address when it starts up by assigning a static IP address to it. 

In this example, we use the following values:

  • IP address: 192.168.0.100
  • Subnet: 255.255.255.0
  • Gateway: 192.168.0.1
  • Hostname: server1.example.com

To configure a static IP address for your MVA, complete the following steps in the console:

  1. Make a backup of the ethernet card configuration file:

    mv  /etc/sysconfig/network-scripts/ifcfg-eth0  /etc/sysconfig/network-scripts/ifcfg-eth0.bak
  2. Edit the ethernet card configuration file:
    vi /etc/sysconfig/network-scripts/ifcfg-eth0
  3. Add or change the default values for IPADDR and NETMASK as follows:
    IPADDR=192.168.0.100
    NETMASK=255.255.255.0
  4. Edit the hosts configuration file:
    vi /etc/hosts
  5. Add a line for your MVA as follows:
    192.168.0.100   server1.example.com     server1
  6. Edit the network configuration file:
    vi /etc/sysconfig/network
  7. Add or change the default values for NETWORKING, HOSTNAME, and GATEWAY as follows:
    NETWORKING=yes
    HOSTNAME=server1.example.com
    GATEWAY=192.168.0.1
  8. Reboot the server:
    reboot

 

Enable SSH (optional)

For security reasons, SSH is disabled by default. If you have a private network, you might want to enable SSH.

To enable SSH, complete the following commands from the console:

  1. Log in with your administrator credentials.
  2. Execute the following command:
    megamon_enable_ssh
  3. Log out.
