editThe following reference file is available with your Auditbeat installation. It
shows all non-deprecated Auditbeat options. You can copy from this file and paste
configurations into the auditbeat.yml
file to customize it.
For rpm and deb, you’ll find the reference configuration file at /etc/auditbeat/auditbeat.reference.yml
. Under
Docker, it’s located at /usr/share/auditbeat/auditbeat.reference.yml
. For mac and win,
look in the archive that you just extracted.
The contents of the file are included here for your convenience.
########################## Auditbeat Configuration ############################# # This is a reference configuration file documenting all non-deprecated options # in comments. For a shorter configuration example that contains only the most # common options, please see auditbeat.yml in the same directory. # # You can find the full configuration reference here: # https://www.elastic.co/guide/en/beats/auditbeat/index.html #============================ Config Reloading ================================ # Config reloading allows to dynamically load modules. Each file which is # monitored must contain one or multiple modules as a list. auditbeat.config.modules: # Glob pattern for configuration reloading path: ${path.config}/conf.d/*.yml # Period on which files under path should be checked for changes reload.period: 10s # Set to true to enable config reloading reload.enabled: false # Maximum amount of time to randomly delay the start of a metricset. Use 0 to # disable startup delay. auditbeat.max_start_delay: 10s #========================== Modules configuration ============================= auditbeat.modules: # The kernel metricset collects events from the audit framework in the Linux # kernel. You need to specify audit rules for the events that you want to audit. - module: audit metricsets: [kernel] kernel.resolve_ids: true kernel.failure_mode: silent kernel.backlog_limit: 8196 kernel.rate_limit: 0 kernel.include_raw_message: false kernel.include_warnings: false kernel.audit_rules: | # Define audit rules here. # Create file watches (-w) or syscall audits (-a or -A). For example: #-w /etc/passwd -p wa -k identity #-a always,exit -F arch=b32 -S open,creat,truncate,ftruncate,openat,open_by_handle_at -F exit=-EPERM -k access # The file integrity metricset sends events when files are changed (created, # updated, deleted). The events contain file metadata and hashes. - module: audit metricsets: [file] file.paths: - /bin - /usr/bin - /sbin - /usr/sbin - /etc # Limit on the size of files that will be hashed. Default is 100 MiB. file.max_file_size: 100 MiB # Hash types to compute when the file changes. Supported types are md5, sha1, # sha224, sha256, sha384, sha512, sha512_224, and sha512_256. Default is sha1. file.hash_types: [sha1] #================================ General ====================================== # The name of the shipper that publishes the network data. It can be used to group # all the transactions sent by a single shipper in the web interface. # If this options is not defined, the hostname is used. #name: # The tags of the shipper are included in their own field with each # transaction published. Tags make it easy to group servers by different # logical properties. #tags: ["service-X", "web-tier"] # Optional fields that you can specify to add additional information to the # output. Fields can be scalar values, arrays, dictionaries, or any nested # combination of these. #fields: # env: staging # If this option is set to true, the custom fields are stored as top-level # fields in the output document instead of being grouped under a fields # sub-dictionary. Default is false. #fields_under_root: false # Internal queue configuration for buffering events to be published. #queue: # Queue type by name (default 'mem') # The memory queue will present all available events (up to the outputs # bulk_max_size) to the output, the moment the output is ready to server # another batch of events. #mem: # Max number of events the queue can buffer. #events: 4096 # Hints the minimum number of events stored in the queue, # before providing a batch of events to the outputs. # A value of 0 (the default) ensures events are immediately available # to be sent to the outputs. #flush.min_events: 2048 # Maximum duration after which events are available to the outputs, # if the number of events stored in the queue is < min_flush_events. #flush.timeout: 1s # Sets the maximum number of CPUs that can be executing simultaneously. The # default is the number of logical CPUs available in the system. #max_procs: #================================ Processors =================================== # Processors are used to reduce the number of fields in the exported event or to # enhance the event with external metadata. This section defines a list of # processors that are applied one by one and the first one receives the initial # event: # # event -> filter1 -> event1 -> filter2 ->event2 ... # # The supported processors are drop_fields, drop_event, include_fields, and # add_cloud_metadata. # # For example, you can use the following processors to keep the fields that # contain CPU load percentages, but remove the fields that contain CPU ticks # values: # #processors: #- include_fields: # fields: ["cpu"] #- drop_fields: # fields: ["cpu.user", "cpu.system"] # # The following example drops the events that have the HTTP response code 200: # #processors: #- drop_event: # when: # equals: # http.code: 200 # # The following example enriches each event with metadata from the cloud # provider about the host machine.
