![]() ![]() ![]() To route the data, you must use a heavy forwarder, which has the ability to parse data. Edit nf to specify the receiving host and port. The value 0 prevents truncation completely. Configure the third party receiving host to expect incoming data on a TCP port. LINE_BREAKER: a regular expression that specifies the boundary between two events.Should always be at false unless there are compelling reasons not to. TIME_FORMAT: The format of the timestamp in the strptime() notation (see ).It helps the UF to distribute data more evenly among all the receivers. MAX_TIMESTAMP_LOOKAHEAD: The length of the timestamp. The necessity of using nf in Uf is to improve the load balancing during the forwarding of data from UF to receivers.TIME_PREFIX: a regular expression that describes at which point in the event the timestamp starts to be used as _time.If the data passes through a heavy forwarder on its way from the source to the indexer, the parsing phase is usually performed on the RF: in this case, the corresponding configuration must be rolled out on the RF and not on the indexer: The first 6 parameters are used in the nf on the splunk instance that performs the parsing phase, so in most cases an indexer. In this article we present the basic parameters, in the following articles we will show how to handle special log formats using concrete examples. ![]() The following parameters represent the best practices for defining source types, more precisely for configuring line breaking and timestamp recognition – additional parameters for other aspects are of course possible. This module provides a method to deploy Splunk Server or Splunk Universal Forwarder with common configurations and ensure the services maintain a running. Research at Splunk has shown that in some cases, the correct configuration of the source type for a defined amount of data could be reduced by almost 75%!įor each source type there should be a corresponding configuration in a Splunk installation. However, there is always the risk that the default settings do not detect all special cases in the logs 100% correctly, and on the other hand, the default settings are defined to apply to as many cases as possible – which is anything but performance-optimized. Splunk comes with some default settings that try to cover these aspects as well as possible, even without explicit configuration. Version 9.0.5 This file contains possible setting/value pairs for configuring Splunk softwares processing properties through nf. splitting large blocks of data into individual events, and timestamp recognition. This sourcetype configuration defines very important aspects of processing incoming data in Splunk, including linebreaking, i.e. One of the issues that occurs in almost every health check is the sub-optimal configuration of source types. As Splunk PS Consultants, we often perform so-called health checks, in which we examine the customer’s Splunk installation and document the opportunities for optimization. ![]()
