I have logstash config file setup as shown below. It is monitoring demo directory for specific file pattern. It finds the log file and reads it, but once it reads it I can't ever convince it to re-read it from the beginning. It's normally a good thing that it remembers, but I'm still working out bugs in my conf file and I need to re-load the index from time to time from the beginning of the file. How can I convince it to read that input file from the beginning once again?!
I've tried the start\_position =\> "beginning", but no luck...
```
Here is my config today:
input {
# Log file
file {
path => "C:/logstash-1.5.3/demo/System*.log"
#type => "sysout"
start_position => "beginning"
}
# Standard input file
#stdin { }
}
filter {
if [path] =~ "SLIC" {
mutate { replace => { "type" => "slic" } }
} else {
mutate { replace => { "type" => "sysout" } }
}
grok {
match => [
"message",
"^\[%{DATESTAMP:tslice} GMT\] %{NUMBER} CurrencyExcha %{GREEDYDATA} (%{WORD:status}(\.)?)"
]
}
if "_grokparsefailure" in [tags] {
drop { }
}
}
output {
elasticsearch {
host => localhost
index => "sprint"
}
stdout {
codec => rubydebug
}
}
```

This is a sincedb issue, there's a bunch of other threads on this so just do a search on that and you should be good 🙂

I have an [open pull request](https://github.com/logstash-plugins/logstash-input-file/pull/61) that attempts to document the sincedb files and related matters a little better. Please feel free to comment if it isn't clear or if it doesn't answer your questions.
