syslog-ng Store Box 7.0.4 LTS - Installation Guide

Installing SSB under Hyper-V

The following describes how to install a new SSB under Hyper-V.

To install a new SSB under Hyper-V

  1. Create the virtual machine for SSB using the following settings:

    • Choose Generation 1 for the virtual machine.

    • Allocate memory for the virtual machine. SSB requires a minimum of 1 GiB of memory, in addition to the memory limit of the indexed logspaces. The recommended size for the memory depends on the exact environment, but consider the following:

      • The base system requires 256 MiB.

      • The syslog-ng server running on SSB requires between 128 MiB and 1 GiB of memory, depending on the message load and on the configuration of SSB.

      • For every logspace, SSB requires additional memory to index the incoming messages. The amount of memory allocated for the indexer can be set individually for every logspace.

    • Configure a fixed size disk with at least 8 GiB space.

      About 5 GB is required for the base system, the remaining disk space is used to store data.

    • Do not use RAID for the hard disk, use the data duplication features of your virtual environment instead. That way, a single hard disk is sufficient for the system. If you need to use the built-in RAID support of SSB for some reason, use two hard disks, and SSB will automatically use them in software RAID.

      		 Caution:

      Hazard of data loss When you install or reinstall SSB in a virtual environment, always create new hard disks. Using existing hard disks can cause unexpected behavior and operational problems.

    • SSB requires that you use either 1 network card or 4 network cards. If you wish to use more than one network card, then after completing the steps of the New Virtual Machine Wizard, add the additional network cards in the Settings of the virtual machine.

      		 Caution:

      Hyper-V offers two kinds of virtual Network Adapters (NICs): Legacy and Synthetic. Due to a known issue (Hyper-V network adapters are mapped to a different eth on every boot), using Legacy and Synthetic NICs within the same configuration will result in improper network setup. If you have to use more than one NICs, we recommend using only Legacy NICs.

  2. Log in to your support portal account and download the latest syslog-ng Store Box installation ISO file. Note that you need to have purchased SSB as a virtual appliance or have partner access to download syslog-ng Store Box ISO files. If you are a partner but do not see the ISO files, you can request partner access within the support portal.

  3. Mount the ISO image and boot the virtual machine. Follow the on-screen instructions to install SSB.

    Once installation successfully completes, the virtual machine will restart automatically.

    In case installation fails, a message will be displayed instructing you to press Ctrl+Alt+Delete to reboot the virtual machine.

Increasing the virtual disk size of SSB under a virtual machine

Increasing the virtual disk size of SSB version 4.9 or later under a virtual machine

SSB can only use fixed disk space assigned to the virtual host. If you must increase the size of the virtual disk, complete the following steps.

Prerequisites:

The following prerequisites are essential for the resize procedure to work:

  • The machine that SSB is running on must be a virtual machine. This procedure will not work on a physical machine.

  • The version running on the virtual machine must be a newly installed SSB 4.9 or later version. This procedure will not work if the SSB installation was upgraded from an earlier version.

  • No software RAID.

To increase the size of the virtual disk

  1. To ensure that no data is lost in case of an error, create a full system backup (configuration and data backup). For detailed instructions, see Data and configuration backups.

  2. Power down the virtual machine.

  3. Increase the storage size.

  4. Restart SSB.

    If you have encountered any errors, contact our Support Team.

    NOTE: Depending on the original size of the virtual disk and on the size you will expand it to, starting the virtual machine for your SSB device after you expanded the size of your virtual disk may take a long time.
