Logstash is not reading all the logs

https://discuss.elastic.co/t/logstash-is-not-reading-all-the-logs/61302

I want my logstash to read the following pattern of files from the logs directory

Current Date File -> server.log
Historical File Name -> server.log.yyyy-mm-dd

In my system I have 22 files in my logs folder

server.log
server.log.2016-09-22
server.log.2016-09-21
server.log.2016-09-20
server.log.2016-09-19
server.log.2016-09-18
server.log.2016-09-17

and so on in this way everyday files are renamed with date appended to name and current date file is named as server.log

my conf file is as follows

input {

file {
type => "serverlog"
path => ["E:/Code_Athon/test/test1/*server.log*"]
start_position => "beginning"

}

}

I found the above configuration does not work for me and is reading only server.log file. No past files 

I also tried the below configurations

input {

file {
type => "serverlog"
path => ["E:/test/test1/server.log","E:/test/test1/server.log*"]
start_position => "beginning"

}

}

In the above configuration i observed that logstash picked up server.log and server.log.2016-09-21 and it does not go to other
files in past , may be because of performance issues or worker thread , but I did not get any error on console. 

input {

file {
type => "serverlog"
path => ["E:/test/test1/server.log","E:/test/test1/server.log*"]
path => ["E:/test/test1/server.log.--*"]
start_position => "beginning"

}

}

Even this configuration does not solve my issue.

Can anyone suggest what should be my configuration so that my lohgstash can read the current file , past file and daily rollover file
named as server.log

Am i missing any configurations here ?

You may need to change the ignore_older8 setting for the file input plugin in order to make Logstash process older files.
