Utilizing the one-line or standalone installer allows you to install the OnSight vCollector on any Linux-based instance.

Resource requirements

The following list provides the minimum Linux VM requirements for a standalone Onsight vCollector deployment:

  • Ubuntu LTS (from 16.04 to 18.04) or RHEL/CentOS 7.x( or newer)
  • Python 2.7x
  • At least 2 CPU cores
  • At least 4 GB of memory
  • 30 GB of available hard disk space 
  • Root access with the ability to create users and install system packages
Information     Note: As your monitoring expands, we recommend 1 core + 1 GB Ram per 1,000 checks.


To install the OnSight vCollector using the standalone installer, perform the following steps. 
  1. Run the following command as root: 
    curl | python /dev/stdin --customer_key <YOUR CUSTOMER KEY>

    where <YOUR CUSTOMER KEY> is your own customer key. To obtain your customer key, select your avatar then select My Account.

    This will add the appropriate repositories to the VM and begin downloading and configuring all dependencies. This process can take up to 15-20 minutes.
  2. Once complete, reboot the VM using the reboot command.
  3. Once the VM is back, login as root again. Upon login, you should see a MOTD which looks similar to the one below:
    Panopta OnSight Monitoring Appliance
    Web Console:
    Agent Proxy:
    OnSight Key: xxxx-xxxx-xxxx-xxxx

  4. You now need to add this vCollector to your Panopta account. Within the Panopta web control panel, select + Add on the top navigation bar then select OnSight vCollector then follow the on-screen instructions. Your OnSight key is what is shown on the MOTD above.
