Hi, I have some big files of log filled each 15 seconds with a heartbeat test result.  
For example one of this file is like this :

```
2018-07-17 10:14:41.646166 TRACE Service:Sales.API Result:OK
2018-07-17 10:14:56.646166 TRACE Service:Sales.API Result:OK
2018-07-17 10:15:10.646166 TRACE Service:Sales.API Result:K0
2018-07-17 10:15:24.646166 TRACE Service:Sales.API Result:OK
2018-07-17 10:18:24.646166 TRACE Service:Sales.API Result:OK

```

For monitoring purpose I am only interested about KO result and detect if the heartbeat ping is not running :

- I want to know if there is a known pattern to aggregate this input and produce at output a summary as follow :
