I am using logstash 2.3.4. I tried to parse a file and output it to stdout. Nothing fancy here. Given below is the config file ` input { file { path =\> "/c/logstash-2.3.4/input.txt" start\_position =\> "beginning" ignore\_older =\> 0 } stdin {} } output { stdout { } } ` Tried everything that is possible. Yet the output fails to appear. Please note that I have already tried everything specified in "[Logstash not showing any output (SOLVED)](https://discuss.elastic.co/t/logstash-not-showing-any-output-solved/28636)" I have deleted sincedb file I have created new files as input files I used stdin as another input source. THAT WORKS FINE What am i missing with respect to text files. Or is logstash not optimised for Windows??? ---

> [@a.madhusudan](#): > > path =\> "/c/logstash-2.3.4/input.txt" This path is on Windows? Please try `"C:\logstash-2.3.4\input.txt"` or `"C:/logstash-2.3.4/input.txt"` Also, running logstash with --verbose will show you what's going on in the background. ---

Thanks This works like a gem I used /c/ as it works in the bash I am using in windows. ---

Hi, ## I am facing the same issue on windows 7. **config file (test.conf):** input { file { path =\> "C:/ElasticSearch/logstash-2.3.4/userdata/sample\_data" start\_position =\> "beginning" sincedb\_path =\> "NUL" ignore\_older =\> 0 } } output { stdout {} } **sample\_data file (some random log):** Date , GPU Core Clock [MHz] , GPU Memory Clock [MHz] , GPU Temperature [°C] , Memory Used [MB] , GPU Load [%] , Memory Controller Load [%] , Video Engine Load [%] , VDDC [V] , 2013-12-30 10:35:32 , 135.0 , 405.0 , 44.0 , 139 , 0 , 5 , 0 , 0.8870 , 2013-12-30 10:35:33 , 135.0 , 405.0 , 43.0 , 139 , 0 , 5 , 0 , 0.8870 , 2013-12-30 10:35:34 , 135.0 , 405.0 , 43.0 , 139 , 0 , 5 , 0 , 0.8870 , 2013-12-30 10:35:35 , 135.0 , 405.0 , 43.0 , 139 , 0 , 5 , 0 , 0.8870 , 2013-12-30 10:35:36 , 135.0 , 405.0 , 43.0 , 139 , 0 , 5 , 0 , 0.8870 , Following is the output from powershell: **PS C:\ElasticSearch\logstash-2.3.4\> .\bin\logstash.bat -f .\bin\test.conf -v** io/console not supported; tty will not be manipulated ←[32mstarting agent {:level=\>:info}←[0m ←[32mstarting pipeline {:id=\>"main", :level=\>:info}←[0m Settings: Default pipeline workers: 2 ←[32mRegistering file input {:path=\>["C:/ElasticSearch/logstash-2.3.4/userdata/sample\_data"], :level=\>:info}←[0m ←[32mStarting pipeline {:id=\>"main", :pipeline\_workers=\>2, :batch\_size=\>125, :batch\_delay=\>5, :max\_inflight=\>250, :level =\>:info}←[0m Pipeline main started My guess is, issue is due to path in windows.

I've removed 'ignore\_older =\> 0' from config file and run, but no success. If needed, I can share --debug output here (although it's very lengthy) Thanks, Abhishek ---

Below are what I got from running Logstash 2.3.3 with your config file and sample data ```auto C:\ELK\logstash-2.3.3\bin>logstash.bat agent -f logstash.conf -r --verbose io/console not supported; tty will not be manipulated ←[32mstarting agent {:level=>:info}←[0m ←[32mstarting pipeline {:id=>"main", :level=>:info}←[0m Settings: Default pipeline workers: 2 ←[32mRegistering file input {:path=>["C:/sample_data"], :level=>:info}←[0m ←[32mStarting pipeline {:id=>"main", :pipeline_workers=>2, :batch_size=>125, :batch_delay=>5, :max_inflight=>250, :l evel=>:info}←[0m Pipeline main started ←[33mReceived an event that has a different character encoding than you configured. {:text=>"Date , GPU Core Clock [ MHz] , GPU Memory Clock [MHz] , GPU Temperature [\\xB0C] , Memory Used [MB] , GPU Load [%] , Memory Controller Load [%] , Video Engine Load [%] , VDDC [V] ,\\r", :expected_charset=>"UTF-8", :level=>:warn}←[0m 2016-08-01T21:58:11.023Z PC-NAME Date , GPU Core Clock [MHz] , GPU Memory Clock [MHz] , GPU Temperature [\xB0C] , M emory Used [MB] , GPU Load [%] , Memory Controller Load [%] , Video Engine Load [%] , VDDC [V] ,\r 2016-08-01T21:58:11.025Z PC-NAME 2013-12-30 10:35:32 , 135.0 , 405.0 , 44.0 , 139 , 0 , 5 , 0 , 0.8870 , 2016-08-01T21:58:11.028Z PC-NAME 2013-12-30 10:35:33 , 135.0 , 405.0 , 43.0 , 139 , 0 , 5 , 0 , 0.8870 , 2016-08-01T21:58:11.028Z PC-NAME 2013-12-30 10:35:34 , 135.0 , 405.0 , 43.0 , 139 , 0 , 5 , 0 , 0.8870 , 2016-08-01T21:58:11.029Z PC-NAME 2013-12-30 10:35:35 , 135.0 , 405.0 , 43.0 , 139 , 0 , 5 , 0 , 0.8870 , ``` Try to run your config on an older version of Logstash to see if it helps. ---

It is working fine now. Problem was with file name extension, I've created data file(sample\_data) using notepad that appends .txt in file name. I am from Unix background, so mostly used vi editor. silly mistake ☹ sorry for chaos. Cheers, Abhishek ---
