Configuration changes of syslog-ng peers
Peers running syslog-ng Premium Edition 3.0-6.0.x automatically send a notification to syslog-ng Store Box(SSB) when their configuration has changed since the last configuration reload or restart. Note that peers running syslog-ng Premium Edition version 7.0.x do not send such notifications. These log messages are available at Search > Peer Configuration Change. Note that the log messages do not contain the actual modification, only indicate that the configuration was modified. The following information is available:
-
Timestamp: The time stamp received in the message — the time when the log message was created in YEAR-MONTH-DAY HOUR:MINUTE:SECOND format.
-
Hostname: The hostname or IP address of the client whose configuration has been changed.
-
Version: The version number of the syslog-ng application that sent the message.
-
Sender address: The IP address of the client or relay that sent the message directly to SSB.
-
Signature: The signature of the syslog-ng client.
-
Fingerprint: The SHA-1 hash of the new configuration file.

Status history and statistics
The syslog-ng Store Box(SSB) appliance displays various statistics and the status history of system data and performance on the dashboard at Basic Settings > Dashboard. The dashboard is essentially an extension of the system monitor: the system monitor displays only the current values, while the dashboard creates graphs and statistics of the system parameters.
The dashboard consists of different modules. Every module displays the history of a system parameter for the current day. To display the graph for a longer period (last week, last month, or last year), select the Week, Month, or Year options, respectively. Hovering the mouse over a module enlarges the graph and displays the color code used on the graph.
To display the statistics of a module as a table for the selected period, click on the graph.
