syslog-ng Store Box 7.4.0 - Administration Guide

Example: Accessing updates example

A customer's Support Service Agreement for syslog-ng Store Box (SSB) has expired and the customer did not renew it. At the time of expiration, the latest available versions were SSB 4 LTS and SSB 4 F3. In this case, the customer can access the current and future revisions of these versions, but they will not have access to future releases such as 4 F4 or 5 LTS when they are released.

Buying a subscription-based license automatically includes product support and access to the latest software versions.

You can download your licenses and the purchased software from the support portal.

Example: A simple example

Scenario:

• You want to deploy an syslog-ng Store Box (SSB) appliance as a log server.
• 45 servers with syslog-ng PE installed in client mode send logs to the SSB log server.
• 45 networks devices without syslog-ng PE installed send logs to the SSB log server.

License requirements: You need a syslog-ng Store Box license for at least 100 Log Source Host (LSH) as there are 90 LSHs (45+45=90) in this scenario.

Example: Using alternative log servers with syslog-ng PE clients

Scenario:

• You want to deploy an SSB appliance as a log server.
• 45 servers with syslog-ng PE installed in client mode send logs to the SSB log server.
• 45 networks devices without syslog-ng PE installed send logs to the SSB log server.
• 100 servers with syslog-ng PE installed send log messages to a log server without syslog-ng PE installed.

License requirements: You need a syslog-ng Store Box license for at least 200 LSHs as there are 190 LSHs (45+45 that send logs to a syslog-ng PE log server, and another 100 that run syslog-ng PE, 45+45+100=190) in this scenario.

Example: Using syslog-ng PE relays

Scenario:

• You want to deploy an SSB appliance as a log server.
• 45 servers with syslog-ng PE installed in client mode send logs directly to the SSB log server.
• 5 servers with syslog-ng PE installed in relay mode send logs to the SSB log server.
• Every syslog-ng PE relay receives logs from 9 networks devices without syslog-ng PE installed (a total of 45 devices).
• 100 servers with syslog-ng PE installed send log messages to a log server without syslog-ng PE installed.

License requirements: You need a syslog-ng Store Box license for at least 200 LSH as there are 195 LSHs (45+5+(5*9)+100=195) in this scenario.

Example: Multiple facilities

You have two facilities (for example, data centers or server farms). Facility 1 has 75 AIX servers and 20 Microsoft Windows hosts, Facility 2 has 5 HP-UX servers and 40 Debian servers. That is 140 hosts altogether.

• Scenario: The log messages are collected to a single, central SSB log server.

  License requirements: You need a syslog-ng Store Box license for 150 LSH as there are 140 LSHs (75+20+5+40) in this scenario.

• Scenario: Each facility has its own SSB log server, and there is no central log server.

  License requirements: You need two separate licenses: a license for at least 95 LSHs (75+20) at Facility 1, and a license for at least 45 LSHs (5+40) at Facility 2. You need a license for 100 LSHs at Facility 1, and a license for 50 LSHs at Facility 2.

• Scenario: The log messages are collected to a single, central SSB log server. Facility 1 and 2 each have a syslog-ng PE relay that forwards the log messages to the central SSB log server.

  License requirements: You need a syslog-ng Store Box license for 150 LSH as there are 142 LSHs (1+75+20+1+5+40) in this scenario (since the relays are also counted as an LSH).

• Scenario: Each facility has its own local SSB log server, and there is also a central SSB log server that collects every log message independently from the two local log servers.

  License requirements: You need three separate licenses. A syslog-ng Store Box a license for at least 95 LSHs (75+20) at Facility 1, a license for at least 45 LSHs (5+40) at Facility 2, and also a license for at least 142 LSHs for the central syslog-ng Store Box log server (assuming that you want to collect the internal logs of the local log servers as well).
