# Auditing — Event batching > Both log and webhook backends support batching. Below is a list of available flags specific to each backend. By default, batching and throttling are enabled for the webhook backend and disabled for the log backend. audit-webhook-mode defines the buffering strategy.

Both log and webhook backends support batching. Below is a list of available flags specific to each backend. By default, batching and throttling are enabled for the webhook backend and disabled for the log backend. audit-webhook-mode defines the buffering strategy. One of the following: batch - buffer events and asynchronously process them in batches. This is the default mode for the webhook backend. blocking - block API server responses on processing each individual event. blocking-strict - Same as blocking, but when there is a failure during audit logging at the RequestReceived stage, the whole request to the kube-apiserver fails. The following flags are used only in the batch mode audit-webhook-batch-buffer-size defines the number of events to buffer before batching. If the rate of incoming events overflows the buffer, events are dropped. The default value is 10000. --audit-webhook-batch-max-size defines the maximum number of events in one batch. The default value is 400. --audit-webhook-batch-max-wait defines the maximum amount of time to wait before unconditionally batching events in the queue. The default value is 30 seconds. --audit-webhook-batch-throttle-enable defines whether batching throttling is enabled. Throttling is enabled by default. --audit-webhook-batch-throttle-qps defines the maximum average number of batches generated per second. The default value is 10. --audit-webhook-batch-throttle-burst defines the maximum number of batches generated at the same moment if the allowed QPS was underutilized previously. The default value is 15. --audit-log-mode defines the buffering strategy. One of the following: batch - buffer events and asynchronously process them in batches. Batching is not recommended for the log backend. blocking - block API server responses on processing each individual event. This is the default mode for the log backend. blocking-strict - Same as blocking, but when there is a failure during audit logging at the RequestReceived stage, the whole request to the kube-apiserver fails. The following flags are used only in the batch mode (batching is disabled by default for the log backend, and when batching is disabled, all batching-related flags are ignored) … Attribution: Adapted from Kubernetes Documentation under CC-BY-4.0.
