So slow in loading the log files via stdin plugin

Elastic Stack Beats

Hi guys,

Currently I need to load some logfiles contained in tar (archive) files. To load them into filebeat, I am using gzcat tool to echo the log files inside the archive files using stdin input for filebeat. For a 200mb log file, it takes more than 1 hour. We wonder if there would be any way to speed things up. I was playing with different buffer size and poolsize options but it did not help much. Also, I tried using an SSD drive instead of a regular hard drive but it did not help much either. Any help would be greatly appreciated.

Thanks,
Andy

Could you share your setup, version of filebeat, config file and the log file? 1h for 200mb sounds way too long.

Which output are you using?

filebeat.prospectors:

  • input_type: stdin
    document_type: log

    multiline.pattern: ^[
    multiline.negate: true
    multiline.match: before

filebeat.spool_size: 8192
filebeat.publish_async: true

output.elasticsearch:
hosts: ["localhost:9200"]
template.enabled: false

template.path: "/etc/filebeat/filebeat.template.json"

output.logstash:
hosts: ["localhost:5044"]
bulk_max_size : 2048
loadbalance: true
workers: 4

you're outputting to ES and LS at the same time. One/both might generate back-pressure, slowing down filebeat.
