vector source There are too many source files

[mlonV]

Use sources as file, hundreds or thousands of files, cpu directly 100%
Why doesn't the "ignore_older_secs" parameter to file feel valid?
It seems that time beyond "ignore_older_secs" should not be detected. I don't know whether there is a problem with my other parameter configuration.

top metrics:

conf sources:
[sources.victory_phpapp]
type = "file"
include = ["/data/logs/app*.log"]
host_key = "hostname"
ignore_older_secs = 60
max_line_bytes = 5242880

Why load so many files already beyond "ignore_older_secs"?
