We are currently using filebeat on a lot of servers, Linux Red Hat 7.2 or Windows 2008 server.
We have no issues with linux servers and we have a very low CPU consuption.
We have some troubles with filebeat 5.5.2 on Windows 2008 servers.
When we have high activity on a Windows server (1.6 GB/h), the CPU usage of filebeat is very high (\> 15%) and it affects significantly our performance mesures.
Looking in code, il seems that buffered I/O are used even for heavily written log files.
Can we suspect a performance hole for this specific case ?
Does it exist a tool to monitor specifically the filebeat process on windows ?
My filebeat.yml (5.5.2)
