Load balance the output hosts
editLoad balance the output hosts
editFilebeat provides configuration options that you can use to fine tune load balancing when sending events to multiple hosts.
To enable load balancing, you specify loadbalance: true
when you configure
the output. For example:
output.logstash: hosts: ["localhost:5044", "localhost:5045"] loadbalance: true
The loadbalance
option is available for Redis, Logstash, and Elasticsearch
outputs. The Kafka output handles load balancing internally.
The load balancer also supports multiple workers per host. The default is
worker: 1
. If you increase the number of workers, additional network
connections will be used. The total number of workers participating
in load balancing is number of hosts * workers
.
Example:
filebeat.inputs: - type: log paths: - /var/log/*.log output.logstash: hosts: ["localhost:5044", "localhost:5045"] loadbalance: true worker: 2
In this example, there are 4 workers participating in load balancing.
