Hello guys. Need some help parsing this log:

```
TNS-12518: TNS:listener could not hand off client connection
 TNS-12547: TNS:lost contact
  TNS-12560: TNS:protocol adapter error
   TNS-00517: Lost contact
    Linux Error: 32: Broken pipe

```

I just want to store the TNS- Errors in a specific field...
