Connecting Logstash to OBS

Overview

Logstash collects data from a multitude of sources, transforms it, and then ships it to the storage system. This section describes how to connect Logstash to OBS.

Precautions

Logstash 7.10.2 or later is recommended.

Procedure

The following uses logstash-7.10.2 as an example.

Download logstash-7.10.2-linux-x86_64.tar.gz and decompress it to the /opt/logstash-7.10.2-linux-x86_64 directory.

Check whether the connection is successful.

Example: Use file as the source and OBS as the destination.

Create a configuration file file2obs.conf. Table 1 describes the parameters. For more information, see Logstash Reference.

         
          
            
            
              input {
  file {
    path => "/opt/nginx/logs/access.log"
    start_position => "beginning"
  }
}

output {
  s3 {
    endpoint => "obs endpoint"   # The endpoint should be an HTTP or HTTPS URL
    access_key_id => "ak"
    secret_access_key => "sk"
    bucket => "obs bucket name"
    size_file => 1048576
    time_file => 1
    prefix => "logstash/"
    enable_metric => true
  }
}
