How to resolve the issue of log4j2 asynchronous log con…
When using log4j2 for asynchronous log consumption, if the consumption thread gets blocked, you can try the following solutions:
- Utilizing an Asynchronous Appender: By using the asynchronous Appender in log4j2, logs can be written to a queue and returned immediately, with background threads responsible for writing logs to the desired output. This helps reduce the main thread’s wait time for logging and prevents blocking.
- Adjusting the size of the log consumption thread pool can enhance the system’s ability to handle multiple tasks concurrently. It is recommended to adjust the thread pool size according to the actual situation to meet the system’s requirements.
- Using an asynchronous log consumer allows for customizing asynchronous log consumption, utilizing multiple threads to process logs. This can be achieved by implementing log processing asynchronously through techniques such as thread pools and queues, avoiding blocking the main thread.
- Utilizing an asynchronous log queue: You can use a blocking queue as a temporary storage for logs, writing the logs into the queue and then immediately returning, with a background consumer thread retrieving the logs from the queue for processing. ArrayBlockingQueue and LinkedBlockingQueue are examples of blocking queues that can be used for this purpose.
The above are some common solutions, and the specific choice can be adjusted and optimized according to the actual situation.
