Wait for the output to acknowledge all events before shutting down. If Filebeat shuts down while itвЂ™s in the process of sending events, it does not In situations where the defined output is blocked and has not confirmed allД®vents, Filebeat will keep trying to send events until the output acknowledges Filebeat is able to achieve this behaviorД«ecause it stores the delivery state of each event in the registry file. How does Filebeat ensure at-least-once delivery? editДЇilebeat guarantees that events will be delivered to the configured output at

See Registry file is too large for details about configuration options that you can set to resolve this issue. If your use case involves creating a large number of new files every day, you might find that the registry file grows to be too large. For each file, Filebeat stores unique identifiers to detect whether a file was harvested previously. Because files can be renamed or moved, the filename and path are not enough to identify a file. When Filebeat is restarted, data from the registry file is used to rebuild the state, and Filebeat continues each harvester at the last known position.ДЇor each input, Filebeat keeps a state of each file it finds. While Filebeat is running, the state information is also kept in memory for each input. If the output, such as Elasticsearch or Logstash, is not reachable, Filebeat keeps track of the last lines sent and will continue reading the files as soon as the output becomes available again. The state is used to remember the last offset a harvester was reading from and to ensure all log lines are sent. How does Filebeat keep the state of files? editДЇilebeat keeps the state of each file and frequently flushes the state to disk in the registry file. New lines are only picked up if the size of the file has changed since the harvester was closed. The log input checks each file to see whether a harvester needs to be started, whether one is already running, or whether the file can be ignored (see ignore_older). Each input type can be defined multiple times. By default, Filebeat keeps the file open until close_inactive is reached.Д¬losing a harvester has the following consequences:ДЇilebeat currently supports several input types. This has the side effect that the space on your disk is reserved until the harvester closes. If a file is removed or renamed while itвЂ™s being harvested, Filebeat continues to read the file. The harvester is responsible for opening and closing the file, which means that the file descriptor remains open while the harvester is running. The harvester reads each file, line by line, and sends the content to the output. What is a harvester? editДЄ harvester is responsible for reading the content of a single file. These components work together to tail files and send event data to the output that you specify. Understanding these concepts will help you make informed decisions about configuring Filebeat for specific use cases.ДЇilebeat consists of two main components: inputs and harvesters. In this topic, you learn about the key building blocks of Filebeat and how they work together.
