The following are the spec and example files for limits.conf.
# Version 6.2.0 # # This file contains possible attribute/value pairs for configuring limits for search commands. # # There is a limits.conf in $SPLUNK_HOME/etc/system/default/. To set custom configurations, # place a limits.conf in $SPLUNK_HOME/etc/system/local/. For examples, see # limits.conf.example. You must restart Splunk to enable configurations. # # To learn more about configuration files (including precedence) please see the documentation # located at http://docs.splunk.com/Documentation/Splunk/latest/Admin/Aboutconfigurationfiles # # limits.conf settings and DISTRIBUTED SEARCH # Unlike most settings which affect searches, limits.conf settings are not # provided by the search head to be used by the search peers. This means that if # you need to alter search-affecting limits in a distributed environment, typically # you will need to modify these settings on the relevant peers and search head for # consistent results. # GLOBAL SETTINGS # Use the [default] stanza to define any global settings. # * You can also define global settings outside of any stanza, at the top of the file. # * Each conf file should have at most one default stanza. If there are multiple default # stanzas, attributes are combined. In the case of multiple definitions of the same # attribute, the last definition in the file wins. # * If an attribute is defined at both the global level and in a specific stanza, the # value in the specific stanza takes precedence. # CAUTION: Do not alter the settings in limits.conf unless you know what you are doing. # Improperly configured limits may result in splunkd crashes and/or memory overuse. * Each stanza controls different parameters of search commands. max_mem_usage_mb = <non-negative integer> * Provides a limitation to the amount of RAM a batch of events or results will use in the memory of search processes. * Operates on an estimation of memory use which is not exact. * The limitation is applied in an unusual way; if the number of results or events exceeds maxresults, AND the estimated memory exceeds this limit, the data is spilled to disk. * This means, as a general rule, lower limits will cause a search to use more disk I/O and less RAM, and be somewhat slower, but should cause the same results to typically come out of the search in the end. * This limit is applied currently to a number, but not all search processors. However, more will likely be added as it proves necessary. * The number is thus effectively a ceiling on batch size for many components of search for all searches run on this system. * 0 will specify the size to be unbounded. In this case searches may be allowed to grow to arbitrary sizes. * The 'mvexpand' command uses this value in a different way. * mvexpand has no combined logic with maxresults * If the memory limit is exceeded, output is truncated, not spilled to disk. * This value is not exact. The estimation can deviate by an order of magnitude or so to both the smaller and larger sides. * Defaults to 200 (MB) min_batch_size_bytes = <integer> * Specifies the size of the file/tar after which the file is handled by the batch reader instead of the trailing processor. * Global parameter, cannot be configured per input. * Note configuring this to a very small value could lead to backing up of jobs at the tailing processor. * defaults to 20 MB [searchresults] * This stanza controls search results for a variety of Splunk search commands. maxresultrows = <integer> * Configures the maximum number of events are generated by search commands which grow the size of your result set (such as multikv) or that create events.
