Hi, i installed logstash as a shipper on a window box with the help of nssm, and configured as below:
input {
file {
type =\> "autolog"
path =\> "E:/elkcluster/log"
}
}
output {
redis {
host =\> "xxx.xxx.xxx.xxx"
port =\> 6379
data\_type =\> "list"
key =\> "dummy"
}
}
Redis is on a linux box, and started with default ports. Below is its logging, looks ok to me.
4554:M 15 Jul 15:35:58.677 # Server started, Redis version 3.0.2
4554:M 15 Jul 15:35:58.678 \* DB loaded from disk: 0.000 seconds
4554:M 15 Jul 15:35:58.678 \* The server is now ready to accept connections on port 6379
I've placed one dummy log file (with two lines: testing, hello world!) in the e:/elkcluster/log folder, but it's seems nothing is going on between the logstash and redis. I'm not sure what went wrong, please help.

By default Logstash tails the input files. What happens if you append a line to the logfile with `echo foo >> E:\elkcluster\log` ?

i don't see any log update at redis side
logstash logging doesn't show anything related to processing the file..
