To know logstash reading progress, I am monitoring .sincedb files. The issue is for large files (say 100-110 MB), .sincedb file is not being created within 0-10 minutes (it takes much more time to create it). I have tried to change the value of 'sincedb\_write\_interval' in config file, but this had no effect. Any idea what is happening here ? What could be the solution for this ?

Please note that the

1. user through which the logstash is being run has the read/write permissions.
2. I have set the path of .sincedb file in the config file.
3. This issue is occurring on versions 2.3.3 as well as 2.4.0.

It is **highly important** to monitor the progress of logstash, without which my application wouldn't work properly as the user needs to be constantly updated about the progress.

Any help would be appreciated... 🙂
