AppProfileSafe writes two independent log streams to separate folders. This page explains where each log type is stored, how files are named, and how rotation works.

Application Log Location

The application log is stored in the folder configured by <LogFolder> in settings.xml. If no value is set, it falls back to the application's base directory.

Timestamps are in ISO 8601 UTC format. The Component column identifies the class or service that produced the entry.

Application Log Rotation

When app.csv would exceed MaxLogSizeBytes (default: 10 MB), rotation occurs automatically:

1. The oldest rotated file (app.N.csv where N = MaxLogFiles) is deleted if it exists.
2. Each remaining rotated file shifts up by one number: app.1.csv → app.2.csv, etc.
3. The current app.csv is renamed to app.1.csv.
4. A new app.csv is created with a fresh CSV header row.

Rotation settings are configured in settings.xml under the <Logging> element. See Logging & Diagnostics for the available settings.

Audit Log Location

Audit logs are stored in the folder configured by <AuditFolder> in settings.xml.

Unlike the application log, audit logs are not rotated by size. Instead, a new file is created automatically at the start of each month. Old files are archived or deleted based on the retention policy.

Audit Log CSV Columns

Each audit CSV file contains one header row followed by pipe-separated entries with the following columns:

TimestampUtc,SequenceNumber,UserId,UserSid,AuthMethod,MachineName,OsVersion,
ApplicationVersion,Interface,Action,Target,Success,Details,DurationMs,
FileCount,DataSize,RegistryValueCount,ErrorMessage,EntryHash,PreviousHash

The EntryHash and PreviousHash columns form a SHA-256 hash chain for tamper detection. For a full explanation, see Audit Logging.
