TNT4JJava應(yīng)用日志框架
TNT4J是一個(gè)改進(jìn)Log4J新的開源Java應(yīng)用日志框架。用于應(yīng)用程序活動(dòng)的跟蹤、相關(guān)性檢查、診斷，可以跨多個(gè)應(yīng)用程序，運(yùn)行時(shí)，服務(wù)器，地理的位置。這個(gè)API是專門用以解決分布式，并發(fā)，多線程，多用戶應(yīng)用，包括活動(dòng)的相關(guān)性，應(yīng)用程序的狀態(tài)轉(zhuǎn)儲(chǔ)，性能和用戶定義的量度。
以下是它的特性：
Simple programming model to facilitate fast root-cause, log analysis
Automated timing of application activities and sub-activities (elapsed, idle time, message age)
Application state dump framework for reporting internal variables, data structures
Granular conditional logging based on application tokens, patterns, that can be shared accross applications, runtimes
Share logging context across application, thread, runtime boundaries
Inter-log correlation of log entries (correlators and tags) between multiple related applications
Intra-log correlation of related activities and sub-activities between multiple applications and threads
Event location tags such as GPS, server etc.
Message flow direction for composite applications that exchange messages (e.g. SOAP, JMS, and SQL etc.)
User defined properties such as CPU, memory logging, thread statistics per process/thread
Extensible activity, sink, error listeners for pre, post event processing
Granular context such as thread id, process id, server, application name
1. 不需要寫 "logger.isDebugEnabled()"
2. can log based on filter (e.g wait time longer than certain value)
3. share logging context across apps. 調(diào)用路徑信息串聯(lián)起來
4. logging statistics關(guān)于日志的統(tǒng)計(jì)信息
