Licensing model and modes of operation

A Log Source Host (LSH) is any host, server, or device (including virtual machines, active or passive networking devices, syslog-ng clients and relays, and so on) that is capable of sending log messages. Log Source Hosts are identified by their IP addresses, so virtual machines and vhosts are separately counted.

The syslog-ng Store Box appliance as a central log-collecting server that receives messages through a network connection, and stores them locally, or forwards them to other destinations or external systems (for example, a SIEM or a database). The SSB appliance requires a license file, this license file determines the number of Log Source Hosts (LSHs) that can send log messages to the SSB server.

Note that the number of source hosts is important, not the number of hosts that directly sends messages to SSB: every host that send messages to the server (directly or using a relay) counts as a Log Source Host.

For technical reasons, the syslog-ng Store Box appliance itself counts as two LSHs in standalone mode, and three LSHs in high-availability (HA) mode. This is automatically adjusted when One Identity generates the license file.

Notes about counting the licensed hosts

Caution:
  • If the actual IP address of the host differs from the IP address received by looking up its IP address from its hostname in the DNS, the syslog-ng server counts them as two different hosts.
  • The chain-hostnames() option of syslog-ng can interfere with the way SSB counts the log source hosts, causing syslog-ng to think there are more hosts logging to the central server, especially if the clients sends a hostname in the message that is different from its real hostname (as resolved from DNS). Disable the chain-hostnames() option on your log source hosts to avoid any problems related to license counting.
  • If the number of Log Source Hosts reaches the license limit, the SSB server will not accept connections from additional hosts. The messages sent by additional hosts will be dropped, even if the client uses a reliable transport method (for example, RLTP).
  • If the no-parse flag is set in a message source on the SSB server, SSB assumes that the message arrived from the host (that is, from the last hop) that sent the message to SSB, and information about the original sender is lost.

Licensing benefits

Buying a syslog-ng Store Box (SSB) license permits you to perform the following:

  • Deploy one instance of the syslog-ng Store Box appliance as a central log collector server.
  • The syslog-ng Store Box license also allows you to download the syslog-ng Premium Edition application (including the syslog-ng Agent for Windows application) and install it on hosts within your organization (on any supported platform) to use it as a log collector agent (client) for syslog-ng Store Box. You cannot redistribute the application to third parties.

The syslog-ng Store Box license determines the number of individual hosts (also called log source hosts) that can send log messages to SSB.

License grants and legal restrictions are fully described in the Software Transaction, License and End User License Agreements. Note that the Software Transaction, License and End User License Agreements and the syslog-ng Store Box Product Guide apply only to scenarios where the Licensee (the organization who has purchased the product) is the end user of the product. In any other scenario — for example, if you want to offer services provided by syslog-ng Store Box to your customers in an OEM or a Managed Service Provider (MSP) scenario — you have to negotiate the exact terms and conditions with One Identity.
