| Parameter | Description | Example | ||
|---|---|---|---|---|
| Engine parameters | ||||
| LogFileName | Engine's log file name. If this parameter is commented or empty, the engine.log" will be used. | LogFileName = FIXAntenna_C++.log | ||
| LogDirectory | This property is the path of the directory in which the logs for all incoming (if LogIncomingMessages is set to 'true') and outgoing FIX messages are stored. It is possible to specify a path related to the EngineRoot directory. For example if LogDirectory is set to '\logs\' then the real path is $(EngineRoot)/logs. The specified directory must exist. | LogDirectory = logs | ||
| Session parameters | ||||
| Debug.LogSessionExtraParameters | If this property value is true, general and extra session parameters of primary and backup connections will be printed to the log file. If this property value is false, only general session parameters of primary and backup connections will be printed to the log file. All FIXEdge-specific session parameters will be printed to the log regardless of Debug.LogSessionExtraParameters property value. | Debug.LogSessionExtraParameters = true | ||
| Session parameters: Storages | ||||
| LogIncomingMessages | This property provides an option to log incoming FIX messages (those received) from a counterparty FIX Engine. They will be stored in the directory specified by the LogDirectory parameter in a file with the extension 'in'.
| LogIncomingMessages = true | ||
| TimestampsInLogs | An option to write timestamps in the log files. This parameter is optional, the default value is true.
| TimestampsInLogs = true | ||
EnableIncrementalLogFileCreation | Setting property "true" will reserve 10Mb of disc space for logging. If the log file reaches 10Mbs, another 10Mbs will be reserved, and so on. When the property is set to "true" FixAntenna performance is greatly increased. | EnableIncrementalLogFileCreation = true | ||
| Persistents.LogIncrementSize | This property specifies the amount of memory reserved for memory-mapped file message storage for out/in file.
| Persistents.LogIncrementSize = 1000000 | ||
| Persistents.IdxIncrementSize | This property specifies the amount of memory reserved for memory-mapped file message storage for idx file.
| Persistents.IdxIncrementSize = 10000 | ||
| SplitPersistentMsgStorage.MaxSliceSize | This property specifies the maximum size of one slice for sliced message storage. Note: Storage slices are created with step, specified with Persistents.LogIncrementSize parameter value. If the MaxSliceSize value is no multiple of Persistents.LogIncrementSize, the result file size will be less, than specified. If value is less than LogIncrementSize, LogIncrementSize value will be used. Recommended value: any multiple of Persistents.LogIncrementSize Default value is 500000000 - 500Mb. | SplitPersistentMsgStorage.MaxSliceSize = 500000000 | ||
| SplitPersistentMsgStorage.BackupDir | This property is the path of the directory, where sliced message storage will search for log files in case they are not found in the primary location. It is the user's responsibility to move files from the primary location to the backup. The default value is empty - backup path disabled. | SplitPersistentMsgStorage.BackupDir = logs/BackupDir | ||
| MessageStorage.IndexRebuildEnabled | Optional. If this parameter is set to 'true', FIX Engine will try to restore the index file from the log file in case the index file is missed or corrupted. The default value is false.
| MessageStorage.IndexRebuildEnabled = false | ||
| NewFeatures.EnableOptimizedPersistentMMIndex | Optional. This property enables the method of maintaining the start-up of FIX sessions with log files in the PersistentMM storage marked with the 'correctly stored' flag. If this property is set to 'true' FIXEdge will skip the check of the 'stored correctly' log files in order to improve performance. Formats of PersistentMM log files with and without enabled NewFeatures.EnableOptimizedPersistentMMIndex property are incompatible. The default value is 'true'.
| NewFeatures.EnableOptimizedPersistentMMIndex = true | ||
| Session parameters: Unregistered Acceptors parameters | ||||
| UnregisteredAcceptor.SessionStorageType | Optional. Commented. Defines the storage type for unregistered sessions. Valid values: "persistent" | "persistentMM" | "splitPersistent" | "transient" | "null" | UnregisteredAcceptor.SessionStorageType = persistent | ||
| Backup parameters | ||||
| BackupDirectory | Relative path to the backup folder. This folder will be used for message storage files of the backup connections. | BackupDirectory = logs/backup | ||
| HiddenLogonCredentials | Optional. Provides an option to mask password in in/out log files. Valid values: "true" | "false". Default value: HiddenLogonCredentials = false | HiddenLogonCredentials = true | ||
| Logging parameters: refer to Logging parameters page for details. | ||||

| Parameter | Description | Example | ||
|---|---|---|---|---|
FixLayer.FixEngine.Sessions.ArchivePath | Defines the path to move log files after the session is closed. Note: directory must exist otherwise the backup procedure will fail.
| FixLayer.FixEngine.Sessions.ArchivePath = FixEdge1/log/archive | ||
| FixLayer.FixEngine.Session.Session_Name.StorageType | Mandatory. Defines the session storage type. Valid values: "persistent" | "persistentMM" | "splitPersistent" | "transient" | "null" | FixLayer.FixEngine.Session.TestFIXAcceptor.StorageType = persistentMM | ||
| FixLayer.FixEngine.Session.Session_Name.LogDirectory | Optional. Defines the path to the directory in which logs of the primary connection of the session are stored. If this property was not specified with value then the value of the LogDirectory will be used. Since FIXEdge C++ 6.14.3 release, If this property was specified with the non-existent path then FIXEdge C++ will try to create a new directory in the specified path.
| FixLayer.FixEngine.Session.TestFIXAcceptor.LogDirectory = FixEdge1/logs | ||
| FixLayer.FixEngine.Session.Session_Name.Backup.LogDirectory | Optional. Defines the path to the directory in which logs of the backup connection of the session are stored. If this property was not specified with value then the value of the BackupDirectory will be used.
| FixLayer.FixEngine.Session.TestFIXAcceptor.Backup.LogDirectory = FixEdge1/logs/backup | ||
| Logging parameters: refer to Logging parameters page for details. | ||||
If you want FIXEdge to store logs in system logs or print it to the console you should change Log.Device property:
