Can you name alternative tools used for log processing and transport, similar to Logstash?

Alternatives to Logstash for log processing and transportation include:

• Fluentd — a universal log collector with a large number of plugins, supporting various sources and outputs.
• Filebeat — a lightweight agent from Elastic, designed to send logs to Elasticsearch or Logstash.
• Graylog — a platform for collecting, indexing, and analyzing logs with a web interface.
• Vector — a modern tool for collecting and processing logs and metrics with high performance.
• rsyslog and syslog-ng — classic system daemons for collecting and routing logs.

The choice depends on performance requirements, ease of configuration, and integration with other systems.
