So, you need to check if your secondary plugin works with the primary setting. The retry wait time doubles each time (1.0sec, 2.0sec, 4.0sec, ...) until retry_max_interval is reached. This action is suitable for streaming. Parser Plugins. Language Bindings. If the queue length exceeds the specified limit (queue_limit_length), new events are rejected. If plugins continue to fail writing buffer chunks and exceeds the timeout threshold for retries, then output plugins will delegate the writing of the buffer chunk to the secondary plugin. limit" and "queue limit" parameters (See the diagram below).

If true, the output plugin will retry after a randomized interval not to do burst retries. parameter for details), the sleep interval can be up to approximately 131072 seconds (roughly 36 hours) in the default configurations. Please consider improving destination settings to resolve BufferOverflowError or use @ERROR label for routing overflowed events to another backup destination (or secondary with lower retry_limit). Since td-agent will retry 17 times before giving up by default (see the retry_limit parameter for details), the sleep interval can be up to approximately 131072 seconds (roughly 36 hours) in the default configurations. Enable Elastic Search output plugin. Write any input, filter or output plugin in C language. *.log, buffer_path /my/buffer/myservice/access.myservice_name.*.log.

For other configuration parameters available in. There are three types of output plugins: Non-Buffered, Buffered, and Time Sliced. For td-agent, run For oms-agent, run But, we recommend to use in/out forward plugin to communicate with two Fluentd instances due to at-most-once and at-least-once semantics for rigidity.. Google Cloud BigQuery. The initial and maximum intervals between write retries. If retry_timeout is the default, the number is 17 with exponential backoff. The interval doubles (with +/-12.5% randomness) every retry until, Same as Buffered Output but default value is changed to, If this article is incorrect or outdated, or omits critical information, please.
