Many user trace sessions may run simultaneously. Is automatically resumed by Firebird as soon as room is available.

The log file name can be set in the nf on a per-database (per-service) basis. Output is read by initiated service connection (the log starts and stops with session begin and end). The log files are not deleted by Firebird. The log is not preserved after Firebird shutdown. However the functionality of the two session types are different:Īlways initiated by the user via a special service (application or similar).Īlways initiated only by Firebird itself. The system audit is described in detail in the Firebird 2.5 Release Notes.

The template file nf, found in Firebird's root directory, contains the full list of available events, with format, rules and syntax for composing an audit trace configuration file. It is sufficiently flexible to allow different sets of events for different databases to be logged to separate log files. A configuration file contains list of traced events and points to the placement of the trace log(s) for each event. By default, the value of this parameter is empty, indicating that no system audit tracing is configured. A parameter in nf, called AuditTraceConfigFile, points to the name and location of the trace configuration file, which is consulted every time a system audit session is started.

Audit services: The system audit session is started by the Firebird engine itself.

A user trace does not stay alive when the Firebird server process gets restarted, but needs to be started manually again. Logged statements are stored on the server in a temporary file, until the initiating application fetches the trace data via the services API. Trace sessions can be configured and controlled using this IBExpert menu item.

User trace session: Each trace session has its own configuration, state and output and is managed by users.

Logged statements as input for a security auditĬomparison of user and audit trace sessions.

Usage statistics for resource and load planning.

Examiniation of performance problems when COMMIT RETAINING (soft commit) or COMMIT (hard commit) is used by your application.

Execution trace for an existing (third-party) application (black-box debugging).

Number of executed statements in a particular time period.

The following scenarios are common examples for an audit/trace: With the audit/trace facility, this probably can only be done with advanced data analysis tasks on the log data stream (if at all).

For example, if you wish to know the number of currently active transactions inside a database, simply query the MON$TRANSACTIONS table. Nevertheless, an audit/trace does not replace the monitoring tables, because with the monitoring tables, the user can query a snapshot of the current state of a database, whereas an audit/trace can be compared with a sequential stream of logged statements. It is also possible to save filtered data as a trace log file.

Firebird 3 log_function_start/log_function_finishĪnalysis of large trace logs: The main idea is to retrieve only necessary items from a trace log file using the Grid View mode with applied filter criteria.

START/FINISH of stored procedures and triggers.

PREPARE/START/FINISH/FREE of SQL statements.

Some of the supported statements include:

Engine activity logging for a specified period of time (be it hours or a whole day) for later analysis.

Interactive trace of specified activity in specified database(s).

Two different kinds of traces can be performed: user traces and a system audit.

(This feature is unfortunately not included in the free IBExpert Personal Edition.) This feature enables you to look inside the Firebird engine and log various events for real-time analysis. This menu item supports the Firebird 2.5 Trace and audit services, initially developed from the TraceAPI contributed by Nickolay Samofatov that he had developed for Red Soft Database, a commercial product based on Firebird's code.
