- # ======================== Elasticsearch Configuration =========================
- #
- # NOTE: Elasticsearch comes with reasonable defaults for most settings.
- # Before you set out to tweak and tune the configuration, make sure you
- # understand what are you trying to accomplish and the consequences.
- #
- # The primary way of configuring a node is via this file. This template lists
- # the most important settings you may want to configure for a production cluster.
- #
- # Please consult the documentation for further information on configuration options:
- # https://www.elastic.co/guide/en/elasticsearch/reference/index.html
- #
- # ---------------------------------- Cluster -----------------------------------
- #
- # Use a descriptive name for your cluster:
- #
- #cluster.name: my-application
- #
- # ------------------------------------ Node ------------------------------------
- #
- # Use a descriptive name for the node:
- #
- #node.name: node-1
- #
- # Add custom attributes to the node:
- #
- #node.attr.rack: r1
- #
- # ----------------------------------- Paths ------------------------------------
- #
- # Path to directory where to store the data (separate multiple locations by comma):
- #
- path.data: /var/lib/elasticsearch
- #
- # Path to log files:
- #
- path.logs: /var/log/elasticsearch
- #
- # ----------------------------------- Memory -----------------------------------
- #
- # Lock the memory on startup:
- #
- #bootstrap.memory_lock: true
- #
- # Make sure that the heap size is set to about half the memory available
- # on the system and that the owner of the process is allowed to use this
- # limit.
- #
- # Elasticsearch performs poorly when the system is swapping the memory.
- #
- # ---------------------------------- Network -----------------------------------
- #
- # Set the bind address to a specific IP (IPv4 or IPv6):
- #
- #network.host: 192.168.0.1
- #
- # Set a custom port for HTTP:
- #
- #http.port: 9200
- #
- # For more information, consult the network module documentation.
- #
- # --------------------------------- Discovery ----------------------------------
- #
- # Pass an initial list of hosts to perform discovery when this node is started:
- # The default list of hosts is ["127.0.0.1", "[::1]"]
- #
- #discovery.seed_hosts: ["host1", "host2"]
- #
- # Bootstrap the cluster using an initial set of master-eligible nodes:
- #
- #cluster.initial_master_nodes: ["node-1", "node-2"]
- #
- # For more information, consult the discovery and cluster formation module documentation.
- #
- # ---------------------------------- Gateway -----------------------------------
- #
- # Block initial recovery after a full cluster restart until N nodes are started:
- #
- #gateway.recover_after_nodes: 3
- #
- # For more information, consult the gateway module documentation.
- #
- # ---------------------------------- Various -----------------------------------
- #
- # Require explicit names when deleting indices:
- #
- #action.destructive_requires_name: true
- [root@elk-monitor ~]# ^C
- [root@elk-monitor ~]# cat /etc/logstash/
- conf.d/ log4j2.properties logstash.yml pipelines.yml
- jvm.options logstash-sample.conf main.conf startup.options
- [root@elk-monitor ~]# cat /etc/logstash/logstash.yml
- # Settings file in YAML
- #
- # Settings can be specified either in hierarchical form, e.g.:
- #
- # pipeline:
- # batch:
- # size: 125
- # delay: 5
- #
- # Or as flat keys:
- #
- # pipeline.batch.size: 125
- # pipeline.batch.delay: 5
- #
- # ------------ Node identity ------------
- #
- # Use a descriptive name for the node:
- #
- # node.name: test
- #
- # If omitted the node name will default to the machine's host name
- #
- # ------------ Data path ------------------
- #
- # Which directory should be used by logstash and its plugins
- # for any persistent needs. Defaults to LOGSTASH_HOME/data
- #
- path.data: /var/lib/logstash
- #
- # ------------ Pipeline Settings --------------
- #
- # The ID of the pipeline.
- #
- # pipeline.id: main
- #
- # Set the number of workers that will, in parallel, execute the filters+outputs
- # stage of the pipeline.
- #
- # This defaults to the number of the host's CPU cores.
- #
- # pipeline.workers: 2
- #
- # How many events to retrieve from inputs before sending to filters+workers
- #
- # pipeline.batch.size: 125
- #
- # How long to wait in milliseconds while polling for the next event
- # before dispatching an undersized batch to filters+outputs
- #
- # pipeline.batch.delay: 50
- #
- # Force Logstash to exit during shutdown even if there are still inflight
- # events in memory. By default, logstash will refuse to quit until all
- # received events have been pushed to the outputs.
- #
- # WARNING: enabling this can lead to data loss during shutdown
- #
- # pipeline.unsafe_shutdown: false
- #
- # ------------ Pipeline Configuration Settings --------------
- #
- # Where to fetch the pipeline configuration for the main pipeline
- #
- # path.config:
- #
- # Pipeline configuration string for the main pipeline
- #
- # config.string:
- #
- # At startup, test if the configuration is valid and exit (dry run)
- #
- # config.test_and_exit: false
- #
- # Periodically check if the configuration has changed and reload the pipeline
- # This can also be triggered manually through the SIGHUP signal
- #
- # config.reload.automatic: false
- #
- # How often to check if the pipeline configuration has changed (in seconds)
- #
- # config.reload.interval: 3s
- #
- # Show fully compiled configuration as debug log message
- # NOTE: --log.level must be 'debug'
- #
- # config.debug: false
- #
- # When enabled, process escaped characters such as \n and \" in strings in the
- # pipeline configuration files.
- #
- # config.support_escapes: false
- #
- # ------------ Module Settings ---------------
- # Define modules here. Modules definitions must be defined as an array.
- # The simple way to see this is to prepend each `name` with a `-`, and keep
- # all associated variables under the `name` they are associated with, and
- # above the next, like this:
- #
- # modules:
- # - name: MODULE_NAME
- # var.PLUGINTYPE1.PLUGINNAME1.KEY1: VALUE
- # var.PLUGINTYPE1.PLUGINNAME1.KEY2: VALUE
- # var.PLUGINTYPE2.PLUGINNAME1.KEY1: VALUE
- # var.PLUGINTYPE3.PLUGINNAME3.KEY1: VALUE
- #
- # Module variable names must be in the format of
- #
- # var.PLUGIN_TYPE.PLUGIN_NAME.KEY
- #
- # modules:
- #
- # ------------ Cloud Settings ---------------
- # Define Elastic Cloud settings here.
- # Format of cloud.id is a base64 value e.g. dXMtZWFzdC0xLmF3cy5mb3VuZC5pbyRub3RhcmVhbCRpZGVudGlmaWVy
- # and it may have an label prefix e.g. staging:dXMtZ...
- # This will overwrite 'var.elasticsearch.hosts' and 'var.kibana.host'
- # cloud.id: <identifier>
- #
- # Format of cloud.auth is: <user>:<pass>
- # This is optional
- # If supplied this will overwrite 'var.elasticsearch.username' and 'var.elasticsearch.password'
- # If supplied this will overwrite 'var.kibana.username' and 'var.kibana.password'
- # cloud.auth: elastic:<password>
- #
- # ------------ Queuing Settings --------------
- #
- # Internal queuing model, "memory" for legacy in-memory based queuing and
- # "persisted" for disk-based acked queueing. Defaults is memory
- #
- # queue.type: memory
- #
- # If using queue.type: persisted, the directory path where the data files will be stored.
- # Default is path.data/queue
- #
- # path.queue:
- #
- # If using queue.type: persisted, the page data files size. The queue data consists of
- # append-only data files separated into pages. Default is 64mb
- #
- # queue.page_capacity: 64mb
- #
- # If using queue.type: persisted, the maximum number of unread events in the queue.
- # Default is 0 (unlimited)
- #
- # queue.max_events: 0
- #
- # If using queue.type: persisted, the total capacity of the queue in number of bytes.
- # If you would like more unacked events to be buffered in Logstash, you can increase the
- # capacity using this setting. Please make sure your disk drive has capacity greater than
- # the size specified here. If both max_bytes and max_events are specified, Logstash will pick
- # whichever criteria is reached first
- # Default is 1024mb or 1gb
- #
- # queue.max_bytes: 1024mb
- #
- # If using queue.type: persisted, the maximum number of acked events before forcing a checkpoint
- # Default is 1024, 0 for unlimited
- #
- # queue.checkpoint.acks: 1024
- #
- # If using queue.type: persisted, the maximum number of written events before forcing a checkpoint
- # Default is 1024, 0 for unlimited
- #
- # queue.checkpoint.writes: 1024
- #
- # If using queue.type: persisted, the interval in milliseconds when a checkpoint is forced on the head page
- # Default is 1000, 0 for no periodic checkpoint.
- #
- # queue.checkpoint.interval: 1000
- #
- # ------------ Dead-Letter Queue Settings --------------
- # Flag to turn on dead-letter queue.
- #
- # dead_letter_queue.enable: false
- # If using dead_letter_queue.enable: true, the maximum size of each dead letter queue. Entries
- # will be dropped if they would increase the size of the dead letter queue beyond this setting.
- # Default is 1024mb
- # dead_letter_queue.max_bytes: 1024mb
- # If using dead_letter_queue.enable: true, the directory path where the data files will be stored.
