JDLogger
.NET 애플리케이션을 위한 경량화된 SQLite 기반의 로깅 라이브러리입니다.
프로그램 로깅과 데이터 로깅을 모두 지원하며, 구조화된 로그 데이터를 쉽게 저장하고 조회할 수 있습니다.
주요 기능
- SQLite 기반의 영구 저장소
- 계층적 로깅 스코프 지원
- 구조화된 로그 데이터 저장
- 예외 정보의 상세한 기록
- 다양한 형식(CSV 등)으로 로그 내보내기
- 커스텀 로그 모델 지원
- 손쉬운 예외 처리 및 로깅
- Thread-Safe하게 설계된 로깅
시작하기
설치
dotnet add package JDLogger
초기화
- 초기화를 하지 않고 사용하는 경우
jd__program_log.db
라는 파일로 자동으로 초기화됩니다.
// 기본 초기화
JDLogger.Initialize("my_log.db");
// 커스텀 매퍼와 함께 초기화
JDLogger.Initialize("my_log.db", new[] {
new ProductLogMapper()
});
사용 예제
1. 기본적인 로깅
static void ApplicationLogExample()
{
var log = JDLogger.BeginScope<Program>();
log.Log(LogLevel.Information, "프로그램 시작");
// 로그 조회 및 내보내기
log.Where(entity => entity.Level == LogLevel.Information)
.Export("log.csv", JDLoggerFormatter.Csv);
}
2. 커스텀 데이터 로깅
static void ProductLogExample()
{
var log = JDLogger.BeginScope<TestSequence>();
var productLog = new ProductLog
{
LotId = "LOT001",
ProductName = "TestProduct",
};
log.Log(productLog);
}
3. 로그 처리기
- 로그가 작성 된 이후 처리를 위한 처리기 등록이 가능합니다.
static void ProductLogExample()
{
var log = JDLogger.BeginScope<TestSequence>();
// 로그 처리기 등록
log.WhenLogged<TestSequence, ProductLog>(x => {
Console.WriteLine(x.ProductName);
});
// 테스트용 로그 작성
var productLog = new ProductLog
{
LotId = "LOT001",
ProductName = "TestProduct",
};
log.Log(productLog);
}
4. 예외 처리 및 로깅
- 예외가 발생할 가능성이 높은 작업을 기록합니다.
operationName
를 통해 어떤 작업 도중 예외가 발생 했는지 작업 단위의 추적이 가능합니다.
static void UseTryCatchExample()
{
var log = JDLogger.BeginScope<TestSequence>();
// 자동 예외 로깅
log.TryCatch(() =>
{
string[] s = ["a", "b", "c"];
for (int i = 0; i < 100; i++)
{
Console.WriteLine(s[i]); // will throw exception
}
}, operationName: "indexReferenceJob", @continue: true);
// 오늘 발생한 에러 로그 조회
foreach (var ex in log.All().Today().Where(entity => entity.Level == LogLevel.Error))
{
Console.WriteLine(ex.ExceptionData);
}
}
5. 타임아웃 로깅
static void TimeoutExample()
{
var logger = JDLogger.BeginScope();
// 동기 버전 사용
bool isTimeout = logger.Timeout(() =>
{
Console.WriteLine("시작");
Thread.Sleep(5000); // 오래 걸리는 작업
Console.WriteLine("중지");
}, milliseconds: 3000, operationName: "긴 작업");
if (isTimeout)
{
Console.WriteLine("타임아웃 발생");
}
}
6. 객체 상태 덤프
static void UseDumpExample()
{
var log = JDLogger.BeginScope<DumpExample>();
// 객체 상태 덤프
var settings = new AppSettings() { Identifier = "Test" };
log.Dump(settings, LogLevel.Critical, message: "객체 상태 덤프");
// 예외 덤프
try
{
throw new NullReferenceException("Exception 데이터 덤프 예제");
}
catch (Exception ex)
{
log.Dump(ex);
}
}
로그 조회를 위한 확장 메서드
시간 기반 필터링
// 오늘 기록된 로그만 조회
var todayLogs = log.All().Today();
// 특정 기간의 로그 조회
var lastWeekLogs = log.All().Between(
DateTime.Now.AddDays(-7),
DateTime.Now
);
로그 레벨 필터링
// 에러 로그만 조회
var errorLogs = log.All().OfLevel(LogLevel.Error);
// 크리티컬 로그만 조회 후 CSV로 내보내기
log.All()
.OfLevel(LogLevel.Critical)
.Export("critical-logs.csv", JDLoggerFormatter.Csv);
최근 로그 조회
// 최근 100개의 로그 조회
var recentLogs = log.All().Recent(100);
// 최근 10개의 에러 로그 조회
var recentErrors = log.All()
.OfLevel(LogLevel.Error)
.Recent(10);
필터 조합하기
// 오늘 발생한 에러 중 최근 5개만 조회
var recentTodayErrors = log.All()
.Today()
.OfLevel(LogLevel.Error)
.Recent(5);
// 지난 주의 크리티컬 로그를 CSV로 내보내기
log.All()
.Between(DateTime.Now.AddDays(-7), DateTime.Now)
.OfLevel(LogLevel.Critical)
.Export("last-week-critical.csv", JDLoggerFormatter.Csv);
커스텀 로그 모델
사용자 정의 로그 모델을 생성하여 특정 도메인의 데이터를 로깅할 수 있습니다:
public class ProductLog : ILogModel
{
[ExportIgnore] public string Scope { get; set; }
public DateTime Time { get; set; }
public string LotId { get; set; }
public string ProductName { get; set; }
}
로그 내보내기
로그를 다양한 형식으로 내보낼 수 있습니다:
// CSV로 내보내기
log.All().Export("logs.csv", JDLoggerFormatter.Csv);
// 헤더를 지정해서 CSV로 내보내기
log.All().Export("logs.csv", new CsvLogFormatter("a,b,c,d,e,f"));
// Json로 내보내기
log.All().Export("logs.csv", JDLoggerFormatter.Json);
// Tab(\t)로 구분된 포멧터로 내보내기
log.All().Export("logs.txt", JDLoggerFormatter.Tabs);
// 헤더를 지정해서서 Tab(\t)로 구분된 포멧터로 내보내기
log.All().Export("logs.txt", new TabDelimitedFormatter("a\tb\tc\td\te\tf"));
// 커스텀 포맷터 사용
var customFormatter = new CustomLogFormatter();
log.All().Export("logs.txt", customFormatter);
ExportIgnore
Attribute를 사용하여 내보내는 컬럼을 무시할 수 있습니다.
// 커스텀 데이터 로깅 모델의 Scope 출력 제어어
public class ProductLog : ILogModel
{
[ExportIgnore] public string Scope { get; set; }
public DateTime Time { get; set; }
public string LotId { get; set; }
public string ProductName { get; set; }
}
