**my perfmon is working but i found a problem with 1 counter "No valid counters"**

**This is the counter**  
C:\>typeperf "\[ASP.NET](http://ASP.NET) Applications(\*)\Requests/Sec"

"(PDH-CSV 4.0)","\ERIKP-PC\[ASP.NET](http://ASP.NET) Applications(\*)\Requests/Sec"  
"09/09/2015 19:20:00.341","0.000000"  
"09/09/2015 19:20:01.341","0.000000"  
"09/09/2015 19:20:02.344","0.000000"  
"09/09/2015 19:20:03.346","0.000000"  
"09/09/2015 19:20:04.349","0.000000"

**Looks good but when i try it in logstash like this**

input {  
perfmon {  
interval =\> 10  
counters =\> ['\[ASP.NET](http://ASP.NET) Applications(\*)\Requests/Sec']  
}  
}

**i get**

{"message":"","@version":"1","@timestamp":"2015-09-09T15:44:23.443Z","host":"ERIKP-PC"}  
{"message":"Exiting, please wait...","@version":"1","@timestamp":"2015-09-09T15:44:23.611Z","host":"ERIKP-PC"}
